In recent years, Congress has increasingly acknowledged how buildings and building codes may

determine the expense and severity of a disaster. Yet the federal government exercises little direct

control over building codes. In general, subfederal governments exercise authority over how
building codes are developed, adopted, and enforced.

Congress has authorized the Federal Emergency Management Agency (FEMA) to utilize a range of policy tools that may
promote a resilient built environment and enforcement of hazard-resistant building codes despite the limitations on federal
authorities. Under both long-standing and recently enacted statutory authorities, FEMA may provide funding to states and
localities to adopt and enforce hazard-resilient building codes, require that federally funded reconstruction efforts adhere to
recent hazard-resistant building codes, and restrict federal funding to rebuild in certain hazard-prone areas. FEMA has, in
turn, recently taken a range of actions to promote the adoption and enforcement of hazard-resistant building codes across the
country, and monitored the weakening or absence of building codes at the subfederal level.
FEMA’s authorities with respect to building codes have generated a number of policy discussions. Issues facing the 118th
Congress include determining the proper role of the federal government in building code and land use policy, how to develop
hazard-resistant building codes in an age of climate change, and how to ensure that code requirements align with FEMA’s
goals to promote equitable disaster recovery and ensure the fair treatment of survivors.
Congress has seen significant legislation introduced in recent years to address the causes and consequences of climate
change—including appropriations and new authorities that enhance FEMA’s building code policies and related activities.
Several recent hearings dedicated to FEMA oversight have centered on the agency’s response to the hazards that climate
change may intensify or make more frequent. In addition, FEMA itself has made climate adaptation a top priority in its
FY2022-26 Strategic Plan. Congress’s potential enhancement of these authorities and oversight of existing authorities could
strengthen FEMA’s role in promoting hazard-resistant building code compliance or, conversely, modify or limit FEMA’s
work in this policy area. This report summarizes this background, discusses FEMA’s role in building code adoption and
compliance, and offers relevant considerations for Congress.

Building Resilience: FEMA’s Building Codes Policies and Considerations for Congress

Introduction
In 1990, a representative of the Federal Emergency Management Agency (FEMA) testified before
Congress that “earthquakes do not kill people, the built environment does.”1 This saying, as well
as similar sentiments, has been included in testimony since at least 1973, well before FEMA
existed.2 According to seismologists and other experts, it is not seismic shaking but “the collapse
or failure of … structures … that ... kill most of the people in an earthquake.”3 Emergency
managers and engineers have long echoed the point that the nature of the built environment often
determines the severity of a disaster no matter whether the inciting event is an earthquake,
hurricane, flood, or fire. How buildings withstand seismic shaking, high winds, floodwaters, or
falling embers may determine the number of casualties, how long the power is out, and how many
millions of dollars would be needed if rebuilding. The potential for hazards to become dangerous,
disruptive, or costly often depends on where and how people build.4
Nearly one-third of the U.S. housing stock is considered to be at high risk of a natural disaster.5
Given that Americans are estimated to spend approximately 90% of their time indoors,6
individuals are most likely to experience a hazard inside of a building. The impacts of natural
hazards are expected to increase during the useful lifetime of much existing and new U.S.
property and infrastructure,7 placing an increasing burden on federal, state, and local
governments, as well as individuals and businesses.
For these reasons, FEMA and other federal agencies have long stressed the importance of hazard-
resistant building codes and land use policy as a means to mitigate disaster losses. The federal
government, however, exercises limited control over such codes and policies. The authority to
adopt, administer, and enforce building codes and facilitate land use largely resides with state,
tribal, territory, and local governments (SLTTs), which do not consistently exercise these
authorities. FEMA has found most jurisdictions lack hazard-resistant codes, and 35 states
received FEMA’s lowest ranking for adopting hazard-resistant building codes.8
To encourage resilience, Congress has authorized FEMA and other federal officials to incentivize
SLTT adoption and enforcement of hazard-resistant building codes and land use policies, and to

require code compliance in federally funded projects. For its part, FEMA has expanded agency
efforts to promote the use of hazard-resistant codes, design, and land use to reduce the risk of
human casualty and structural damage. May has been observed as National Building Safety
Month for several years,9 advocating the importance of building codes.
The 118th Congress faces fundamental questions regarding the built environment in the face of
more numerous, costly, and disruptive disasters.10 Where is it wise to build? How should
buildings in hazardous locations be constructed? The 118th Congress may decide how the federal
government engages with these questions, promotes a hazard-resilient built environment, and
reduces future disaster-related losses.
Terms
Building Codes—Building codes are officially adopted comprehensive specifications regulating building
construction, materials, and performance to protect the public health, safety, and welfare.11 Building codes may
reference more than one design standard.
Design Standard—A design standard is a specified criteria or standard that dictates that a provision, practice,
requirement, or limit be met;12 for example, the use of the 1% annual chance flood or the degree of protection of
a structural project.
Code Development, Adoption, Administration, Enforcement—Building code development refers to
the process of authoring, revising, and approving building codes. Adoption refers to a government’s codification
of a given set of building codes as legally required minimum standards within a given jurisdiction. Administration
and enforcement refers to permitting, certification of compliance and occupancy, fee col ection, training and
employing relevant staff, inspection, monitoring of unpermitted activities, identification of corrective action, and
similar activities.
Natural hazards—FEMA defines natural hazards as environmental phenomena that have the potential to impact
societies and the human environment. Hazardous weather and climate events include severe storms, tropical
cyclones, drought, wildfires, and extreme heat or cold. Other natural hazards include avalanche, earthquake,
landslide, tsunami, and volcanic activity. FEMA distinguishes between natural hazards and natural disasters, which
the agency defines as the negative impact fol owing an actual occurrent of a natural hazard in the event that it
significantly harms a community.13
Value of Building Codes
The federal government has allocated increasing resources to disaster relief and recovery,14 and
the Government Accountability Office (GAO) has found that the rising number of natural

Information, “Billion-Dollars Weather and Climate Disaster,” website, https://www.ncei.noaa.gov/access/billions/. The

1980–2022 annual average is 8.1 events (CPI-adjusted); the annual average for the most recent five years (2018–2022)
is 18.0 events (CPI-adjusted). Overall losses also increase over time; see Adam Smith, “2021 U.S. Billion-dollar

disasters and increasing reliance on the federal government for response and recovery assistance
is a key source of federal fiscal exposure.15 In the United States, as in many countries, these
increasing costs can be attributed to a combination of factors, including increased development in
areas that are susceptible to natural hazards, rising property values in hazardous areas, and
climatological and environmental changes. The role of inadequate building codes is less
frequently considered a contributor to natural disaster losses, despite long-standing information
that may support this connection. For example, although South Florida had one of the strongest
building codes in the nation in 1992, a quarter of the $16 billion in insured losses from Hurricane
Andrew were attributed to Dade County’s failure to enforce its building code.16 Subsequent
research revealed that the construction practices in place at the time were not only insufficient to
withstand the powerful winds, but had also magnified the damage.17 Thirty years later, studies of
damage from Hurricane Ian in southwest Florida found that residential buildings constructed to
the 2002 Florida Building Code or later suffered minimal observable structural damage from
either wind or storm surge, even during a historic storm surge of the magnitude induced by
Hurricane Ian.18
Experts have also pointed out how hazard-resistant building codes reduce earthquake damage. In
2010, both Chile and Haiti were hit by major earthquakes. The magnitude 7 earthquake19 in Haiti
killed an estimated 220,000 people, injured 300,000, and left 1.5 million homeless. The much
stronger magnitude 8.8 earthquake20 in Chile killed less than 800 people, most due to the resulting
tsunami, and caused relatively little structural damage.21 Some of the difference in outcomes
might be attributable to variations in seismic and site characteristics, while much of the difference
in casualties and structural damage has been attributed to the adoption and enforcement of strong

19 The Moment Magnitude, MW, is an indicator of the amount of energy released during an earthquake. The MW scale is
logarithmic, with an increase of one step corresponding to a tenfold increase in the measured amplitude of the ground
motion of the earthquake, and 32 times more energy release. In other words, an MW 8.0 earthquake releases 32 times
more energy than an MW 7.0 earthquake. For more information on how earthquakes are measured, see CRS Report

building codes in Chile, in contrast to the virtually nonexistent and poorly enforced building
codes in Haiti.22
The National Institute of Building Sciences also emphasized the importance of building codes in
a widely cited study which found that adopting the most recent building code could save $11 for
every dollar invested in hazard-resistant codes and standards, and above-code design could save
$4 for each dollar invested. The study also found that adopting the 2015 International Code
Council building codes added about 1% in costs relative to 1990 standards.23
Building Codes and FEMA: Background
State, Local, Federal, and Nonfederal Roles
Role of the International Code Council and Code-Development Organizations
In 1994, the three groups publishing model codes merged to form the International Code Council
(ICC), 24 which published the first International Building Code in 1995.25 The ICC continues to
develop and publish model codes and guides to building practices that are now adopted, adapted,
and enforced at the state, territorial and local level.26 The ICC’s “family” of I-Codes includes
codes for different types of dwellings (e.g., residential, new, existing structures), and was most
recently updated in 2021.27
Federal Role
In the last decades of the twentieth century, the federal government—including FEMA—helped
to develop and promote hazard-resistant building codes promulgated by the ICC and other code-
developing organizations like the American Society of Civil Engineers (ASCE).28
The federal government continues to collaborate with the ICC and similar organizations to help
develop, revise, and promote hazard-resistant model building codes.29 The ICC updates I-Codes
on a three-year cycle and includes hearings and opportunities for public comment.

Building Resilience: FEMA’s Building Codes Policies and Considerations for Congress

State and Local Roles
Most states and local jurisdictions adopt model codes that are created on a national or
international level by standards-developing organizations like the ICC, and amend them where
needed prior to adoption into state laws and local ordinances. Building codes are administered at
a community level; the federal government cannot mandate the level of code enforcement in
states or communities. Some states have adopted statewide building codes that apply to virtually
every type of structure while others employ lesser degrees of regulation and code applicability.
Statewide codes sometimes allow certain individual jurisdictions (e.g., cities or a particular class
of counties) to deviate from the standard, weakening the model minimum code in response to
objections based on the cost of compliance.30
Building Codes Adoption and Enforcement Shortfalls
Nearly two-thirds of Americans live in communities that have not adopted the latest model
building codes,31 and many jurisdictions do not consistently adopt and enforce building codes—
leading to significant threats to public health and individual safety—particularly in the face of a
hazard.32 According to FEMA, 35% of localities across the country have adopted “modern
building codes without weakening the natural hazard-resistant provisions.”33 Most inhabitants are
unaware that they may live in substandard, vulnerable structures, which increases the risk of
damage and casualty.34 Further, FEMA has found that a majority of areas with natural hazard risk
in the United States have not adopted current versions of hazard-resistant building codes.35 In
many regions, low-income or otherwise socially vulnerable households are more likely to live in
areas of higher risk to natural hazards.36 In addition, the U.S. Surgeon General has found that
socially vulnerable populations, including individuals with low-incomes, identifying as racial or
ethnic minorities, and those with disabilities, are more likely to live in substandard housing.37
Often citing these risks, FEMA advocates for the adoption, strengthening, and enforcement of
SLTT building codes.38
Many jurisdictions particularly struggle to adopt and adequately enforce codes in the wake of a
disaster. Local officials may face a large number of damaged structures and a high volume of
permit applications, and there may be pressure on local officials to waive requirements that are

perceived to hamper rapid reconstruction or “getting back to normal.”39 The sudden, widespread
increase in building activity, loss or displacement of workers, and other factors may lead to
personnel shortfalls. For this reason, some jurisdictions have established mutual aid agreements to
allow building departments to augment staff in times of need. FEMA encourages and tracks such
agreements.40
Developing Hazard-Resistant Codes in an Age of Climate Change
Reliance on Historic Hazard Data
In general, existing building codes and standards in the United States are designed to respond to
risks of hazards based on current and historic climate conditions. For example, the ICC codes, or
I-Codes, that FEMA often considers the “consensus-based codes” to which many FEMA-funded
projects must be rebuilt are currently updated every three years. The use of consensus-based
codes, specifications, and standards may not necessarily incorporate the latest hazard-resistant
design,41 and that design may not provide sufficient protection against extreme events or future
conditions.
Standard-developing organizations generally have not used forward-looking climate information,
relying instead on historical observations rather than incorporating long-term planning for climate
hazards or employ climate projections. Further, standards-developing organizations vary in
whether they update the climate information in design standards, building codes, and voluntary
certifications on a regular basis.42 Recent increases in the frequency and intensity of extreme
weather events attributed to climate change,43 coupled with the use of historical data, means that
the codes may more accurately reflect historical dangers than current or future risk.44
For example, the International Building Code allows for some degree of protection against sea
level rise in its elevation requirements, but the ICC recognizes that the code may need to evolve

to respond to changing risk.45 Since 2015, the I-Codes have required at least one foot of freeboard
be incorporated into elevation requirements,46 designed with reference to the elevation of current
assessments of the 1%-annual-chance flood (a flood event with a 1% chance of being equaled or
exceeded in a given year).47 This risk calculation does not account for changes in water level and
hazard probability associated with climate change and extreme events. For example, one study
found that as sea level rises, by the late 21st century the historical 100-year flood would occur
annually in New England and Mid-Atlantic regions and every 1-30 years in the southeast Atlantic
and Gulf of Mexico regions.48
Incorporating Climate Risk into Building Standards
The I-Codes used throughout the United States are developed through a consensus-based process;
because changes to the I-Codes cannot be unilaterally mandated, the ICC is considering potential
strategies that align with the current format of the codes. These include an overlay document
(standard or guideline) that communities seeking to address future climate risk can adopt
alongside their code, or the development of a stand-alone standard that addresses the process that
jurisdictions can use to factor climate change into their codes. Some local jurisdictions, including
New York City and Southeast Florida, have developed design guidance that addresses climate
risk. In New York this guidance currently applies to municipal buildings but may be extended to
all buildings in the future. Local governments in Southeast Florida have developed common sea
level rise projections that can be incorporated into zoning or building code requirement.49
An example of enhanced hazard-resistant standards are the FORTIFIED Home performance-
based engineering and building standards developed by the Insurance Institute for Business and
Home Safety (IBHS), a regular partner of FEMA on building-code related efforts.50 These
standards are designed to help strengthen new and existing homes through the installation of

The ICC participates in the Global Resiliency Dialogue (GRD), a joint initiative with research organizations from
Australia, Canada, New Zealand, and the United States. The GRD is working to inform the development of building
codes that draw on both building science and climate science to improve the resilience of buildings and communities to
intensifying risks from weather-related natural hazards. ICC, Global Resiliency Dialogue,

freeboard. The Base Flood Elevation (BFE) is defined as the water surface elevation of the base flood, which is the 1%-
annual-chance flood, commonly called the 100-year flood. The probability is 1% that rising water will reach BFE
heights in any given year.
47 The area that will be inundated by the 1%-annual-chance flood is known as the Special Flood Hazard Area (SFHA).

Land Use Planning and Hazard Zones
Building codes define what can be built, and how, but generally do not address the question of
where to build—this must be done through land use planning or zoning. The federal government
does not have direct authority over local zoning and land use decisions. The regulation of land
use falls under the states’ police powers, which the Constitution reserves to the states, and the
states delegate this power down to their respective political subdivisions.65 Typically, states
delegate much of their authority for zoning and land use regulation to units of local government.66
Based on this delegated authority, local governments employ zoning ordinances and related
regulations to restrict the location, type, and characteristics of future development and use of land
under their jurisdiction.67 Zoning ordinances are the main instrument to restrict and steer the
development of land within the jurisdiction of a local government. Typically, they contain text-
based and map-based parts that indicate permitted and conditional uses for lots.68

Building Resilience: FEMA’s Building Codes Policies and Considerations for Congress

Planning policies can reduce risk through their control of land use and spatial configurations in
cities. Zoning plans, which govern the location, type, and intensity of new development, may
designate areas for specific purposes or to identify areas of high exposure. For example, by
strategically directing funding for road and utility infrastructure, governments can greatly
influence how and where communities develop.69 Governments may also acquire properties in
hazard-prone locations with public funds and convert them to less hazardous uses; for example,
buying out homes in the floodplain and using the land for a park. This can include acquisition (of
undeveloped land, development rights, or damaged buildings), transfer of development rights to
safer locations, building relocation, and/or demolition of individual or multiple structures.70
FEMA’s Authorities and Land Use Planning
Despite its lack of direct powers to regulate land use planning on nonfederal lands, the federal
government can exercise considerable influence through federal law; for example, the
Endangered Species Act (P.L. 93-205), the Energy Policy Act (P.L. 102-486), the Clean Water Act
(P.L. 95-217), and the National Environmental Policy Act (P.L. 91-190). Much of FEMA’s
authority over land use planning stems from its role in administering the National Flood
Insurance Program (NFIP), which is described below.
Mitigation Plans
The Stafford Act (P.L. 93-288, as amended; 42 U.S.C. §§5151 et seq.) and FEMA regulations
require SLTT governments to have a FEMA-approved mitigation plan as a condition of receiving
certain non-emergency Stafford Act assistance and FEMA mitigation grants, including assistance
through the following programs:71
• Public Assistance (PA) categories C-G;72
• Fire Management Assistance Grants (FMAG);73
• Building Resilient Infrastructure and Communities (BRIC);
• Hazard Mitigation Grant Program (HMGP);
• Hazard Mitigation Grant Program Post Fire (HMGP Post Fire);
• Flood Mitigation Assistance (FMA);

Category E is buildings and equipment, Category F is utilities, and Category G is parks, recreational, and other. See
CRS In Focus IF11529, A Brief Overview of FEMA’s Public Assistance Program, by Erica A. Lee.
73 If a state or tribal government does not have a FEMA-approved mitigation plan in accordance with 44 C.F.R.
§204.51(d)(2), it must formally submit a mitigation plan for FEMA’s review and approval within 30 days of the
FEMA-State Agreement for the FMAG program. FEMA has 45 days to review the plan. FEMA will not approve an
application for assistance under the FMAG program if the state or tribal government does not have an existing FEMA-
approved mitigation plan or fails to submit one within the required timeframe. See FEMA, Fire Management

• Rehabilitation of High Hazard Potential Dams (HHPD); and
• Safeguarding Tomorrow Revolving Loan Fund Program (STRLF).
The mitigation plan demonstrates the SLTT government’s commitment to reduce risks from
natural hazards and serves as a guide for decisionmakers as they commit resources to reducing
the effects of natural hazards.74 States and tribes can submit enhanced hazard mitigation plans in
order to receive increased funds under HMGP. An enhanced hazard mitigation plan should
document that, to the extent allowed by SLTT law, the STT requires or encourages local
governments to use a current version of a nationally applicable model building code or standard
that addresses natural hazards as a basis for design and construction of STT-sponsored mitigation
projects.75 For states with a mandatory statewide building code, the enhanced plan must provide
evidence that the state, among other things, does not allow local governments to weaken the
hazard-resistant provisions of the state building code.76 Enhanced plans must also demonstrate
commitment to a comprehensive mitigation program through a combination of activities that may
include use of a model floodplain ordinance that includes and goes beyond the NFIP minimum
requirements and is coordinated with the state building codes.77
Community Disaster Resilience Zones
The Community Disaster Resilience Zones Act of 2022 (P.L. 117-255, CDRZA), signed into law
in December 2022, amended the Stafford Act to establish a statutory structure to identify and
designate communities most at risk from natural hazards. It also authorized the President to
increase the federal cost share under Section 203 of the Stafford Act—Predisaster Hazard
Mitigation78—to 90% for CDRZA-designated communities and to use funding set aside under
Section 203(i).79
The CDRZA required FEMA to identify and designate Community Disaster Resilience Zones
(CDRZs). At a minimum, CDRZs must include the 50 census tracts assigned the highest
individual hazard risk ratings nationwide. The CDRZA also directed FEMA to ensure geographic
balance by considering designations in coastal, inland, urban, suburban, rural areas and tribal
lands, with not less than 1% of census tracts in each state assigned high individual risk ratings
designated as CDRZs. CDRZs hold their designation for a period not less than five years and
should be reviewed and updated every five years.
The CDRZA requires FEMA to maintain and update a natural hazard assessment program and
products for the public’s use that show the risk of natural hazards through use of risk ratings at the
census tract level. FEMA intends to use the National Risk Index (NRI)80 to satisfy this

80 The National Risk Index (NRI) is an online mapping application that identifies communities most at risk from 18
natural hazards and maps a community’s expected annual loss, social vulnerability, and community resilience. The NRI
provides a baseline relative risk measurement for each county and census tract in the United States. Currently the NRI
does not account for future conditions or anticipated impacts due to climate change. See FEMA, National Risk Index

requirement of the CDRZA, and to use the NRI to identify the communities which are most in
need of assistance for resilience-related projects and thus to be designated as CDRZs. FEMA
issued a notice and request for information on implementation of the CDRZA,81 and expects to
designate CDRZs later in 2023.82
The Federal Flood Risk Management Standard
FEMA, along with other federal agencies, is required to comply with Executive Order (E.O.)
11988—Floodplain Management,83 and E.O. 11990—Protection of Wetlands.84 These Executive
Orders require federal actions85 to avoid, to the extent possible, the long- and short-term adverse
impacts associated with the occupancy and modification of floodplains and to avoid direct and
indirect support of floodplain development wherever there is a practicable alternative. FEMA
implemented E.O. 11988 and E.O. 11990 in regulations in 44 C.F.R. Part 9, which requires
FEMA to use a systematic decisionmaking process to evaluate the potential effects of projects
located in, or affecting, floodplains (the eight-step process).86
In January 2015, President Obama signed Executive Order 1369087 which, among other things,
established a Federal Flood Risk Management Standard (FFRMS) for federally funded projects
that required a higher level of flood resilience than E.O. 11988.88 Federally funded projects are
defined as actions where federal funds are used for new construction, substantial improvement, or
to address substantial damage to structures and facilities.89

Source: CRS, adapted from FEMA, Guidelines for Establishing a FFRMS, p. 51.
Notes: The FFRMS floodplain is the 500-year floodplain, or the area inundated by the 0.2% annual-chance flood.
The current floodplain (the SFHA) is the area inundated by the 1% annual-chance flood.
E.O. 13690 modified the requirements of E.O. 11988, largely by redefining the floodplain at the
foundation of federal floodplain management policy. Rather than relying on the Base Flood
Elevation (BFE) floodplain,90 E.O. 13690 provided that the floodplain be determined by one of
three methods:
1. the freeboard value approach;91
2. the 0.2% annual-chance (500-year) flood approach;92 or
3. the climate-informed science approach.93
FEMA has produced policy guidance for partial implementation of the FFRMS for certain
programs by requiring the use of the FFRMS freeboard approach for certain noncritical actions

guidelines do not require the use of the NFIP definitions of substantial damage and substantial improvement (footnote
144).
90 The Base Flood Elevation (BFE) is defined as the water surface elevation of the base flood, which is the 1%-annual-
chance flood.
91 The floodplain obtained through the freeboard value approach in the FFRMS is defined as the elevation and flood
hazard area that result from adding an additional two feet to BFE for noncritical actions and adding an additional three
feet to BFE for critical actions, which are defined as any activity for which even a slight chance of flooding would be
too great. FEMA’s Guidelines for Establishing a FFRMS provides additional guidance to assist agencies in determining
whether an action is critical.
92 The 500-year floodplain is defined as the area subject to flooding by the 0.2%-annual-chance flood.
93 Defined as the elevation and flood hazard area that result from using a climate-informed science approach that uses
the best-available, actionable hydrologic and hydraulic data and methods that integrate current and future changes in
flooding based on climate science. For additional information on the methods of calculating the FFRMS floodplain, see

involving structures in the Special Flood Hazard Area (SFHA).94 The interim policy applies to
structures in the SFHA that receive funding from any FEMA program (Individual Assistance,
Public Assistance, and Hazard Mitigation Assistance) but does not address the expansion of the
horizontal floodplain or the application of the FFRMS to critical actions. FEMA intends to fully
implement the FFRMS by rulemaking; full implementation of the FFRMS will require an update
to 44 C.F.R. Part 9.95
National Flood Insurance Program Requirements Related to Planning and
Building Codes
The National Flood Insurance Act of 1968 (NFIA)96 requires participating communities to adopt
the minimum NFIP requirements through zoning, floodplain ordinances, and/or building codes.
However, FEMA’s view is the agency has no direct involvement in the administration of local
floodplain management ordinances or in the permitting process for development in the
floodplain.97 Instead, FEMA sets minimum standards that communities must adopt in order to
participate in the NFIP. The NFIA authorizes FEMA to develop criteria designed to encourage,
where necessary, the adoption of adequate state and local measures which, to the maximum event
feasible, will
1. constrict the development of land which is exposed to flood damage where
appropriate;
2. guide the development of proposed construction away from locations which are
threatened by flood hazards;
3. assist in restricting damage caused by floods; and
4. otherwise improve the long-range land management and use of flood-prone
areas.98
In order to accomplish these goals, FEMA has set forth minimum floodplain management
standards in federal regulations.99 These standards only have the force of law because they are
adopted and enforced by a SLTT government. Communities are required to adopt these minimum
floodplain management standards in order to participate in the NFIP.100 FEMA’s land use criteria,
once adopted by the community, take precedence over any less restrictive or conflicting local
laws, ordinances, or codes for floodplain management.101 However, NFIP-participating
communities are permitted and encouraged to adopt higher standards than the minimum set forth
in regulation. FEMA has determined that the flood provisions in the 2021 I-Codes meet or exceed

94 The Special Flood Hazard Area (SFHA) is defined by FEMA as an area with a 1% or greater risk of flooding every
year.

the minimum NFIP standards.102 NFIP minimum standards apply to all new construction in the
SFHA, and requirements for structures in SFHAs cannot be suspended or waived.
In addition to providing flood insurance and requiring communities to reduce flood damage
through floodplain management, the NFIP identifies and maps the nation’s floodplains. Maps
depicting flood hazard information, known as Flood Insurance Rate Maps (FIRMs), are used to
promote awareness of flood hazards and determine the appropriate minimum floodplain
management criteria for flood hazard areas.103 While FEMA is generally responsible for the
development of flood maps, the community itself must pass the map into its local or state law for
the map to be effective (i.e., in force). FIRMs are used for both building code and floodplain
management requirements in SFHAs.104
FEMA: Code Requirements for Funded Projects
Code Requirements: Authorities, Developments, and Variations
across Programs
The Stafford Act, the National Flood Insurance Act, federal regulations, and FEMA policy
generally require recipients of federal assistance to comply with applicable building codes when
conducting federally funded construction projects. Each FEMA grant program includes different
code compliance requirements. For example, a city may rebuild some structures under the PA
program and in line with the required International Building Code (IBC), while repairs to other
projects may be completed under the Hazard Mitigation Grant Program (HMGP), which only
requires compliance with local codes.
These variations have generated criticism. ASCE has urged FEMA to be consistent in the
minimum standards it applies across all of its programs.105 Congress examined this issue at a

Reform Act (DRRA, P.L. 115-254). Many of DRRA’s changes enhanced FEMA’s authorities to
require compliance with consensus-based standards that may exceed locally adopted codes. Table
2 summarizes requirements by FEMA program.
Building Code Development, Adoption,
Enforcement: FEMA Assistance and Incentives
Several FEMA programs provide financial and technical assistance to nonfederal governments for
building code adoption, enforcement, and development—not just assistance to rebuild individual
structures (as summarized in Table 3). Such assistance may be particularly valuable in post-
disaster contexts, when many facilities are undergoing rebuilding simultaneously and
governments may be overwhelmed with permitting, inspections, and their own rebuilding
projects. Governments may be able to receive support for enforcing codes and standards in a wide
range of facilities, including those ineligible for other FEMA assistance (e.g., for-profit entities).
In August 2022, FEMA released a playbook for jurisdictions adopting and enforcing building
codes that included an overview of relevant FEMA assistance.108 Significant updates to these
requirements are forthcoming, such as the adoption of the ASCE 7-22 Flood Supplement 2, which
includes new provisions that protect against 500-year flood events and introduces a new
requirement for relative sea level change as it relates to an individual structure.109
Public Assistance
DRRA amended the Stafford Act to authorize assistance for SLTT governments to administer and
enforce building codes.110 In 2019, FEMA released guidance that partially implemented these
new authorities, primarily through the Public Assistance program. Under that policy, which
remains active, FEMA may provide assistance to fund building code enforcement on disaster-
damaged facilities within 180 days of the related Stafford Act declaration.111

108 For example, FEMA may provide assistance to cover the costs of hiring, training, and supervising building code
staff, reviewing and processing applications for building permits, and inspecting structures under construction for
compliance (apart from the costs incurred while executing the actual reconstruction).

Building Resilience: FEMA’s Building Codes Policies and Considerations for Congress

Hazard Mitigation Assistance
Requirements related to building codes for Hazard Mitigation Assistance (HMA) programs (i.e.,
the Hazard Mitigation Grant Program, the Flood Mitigation Grant Program, the Safeguarding
Tomorrow Revolving Loan Fund Program, and Building Resilient Infrastructure and
Communities) are only mentioned in HMA guidance. All mitigation reconstruction activities112
must be completed in accordance with the latest published editions of the International Codes and
FFRMS requirements. FEMA is to use the latest published edition of ASCE-24 or its equivalent
as the minimum design criteria for all HMA-assisted mitigation reconstruction projects in flood
hazard areas.
Close-out113 requirements for all HMA grants include comments and documentation to support
that the project was completed in compliance with all required permits and building codes and
standards (if applicable).114 However, there is no explicit requirement for proof of compliance
with building code requirements, in contrast to PA, where noncompliance can result in potential
denial or de-obligation of PA funding for a facility.115
Hazard Mitigation Grant Program
The Hazard Mitigation Grant Program (HMGP) is authorized by Stafford Act Section 404—
Hazard Mitigation,116 with the objective of ensuring that the opportunity to take critical mitigation
measures is not lost during the reconstruction process following a disaster. There is no mention of
building code requirements for HMGP in Stafford Act Section 404, nor in HMGP regulations.117
Safeguarding Tomorrow Revolving Loan Fund Program
Hazard mitigation loans are available through the Safeguarding Tomorrow Revolving Loan Fund
Program (STRLF).118 The STRLF program was created by the STORM Act (Safeguarding
Tomorrow through Ongoing Risk Mitigation Act, P.L. 116-284), which amended the Stafford Act
by authorizing FEMA to enter into agreements with eligible entities to establish hazard mitigation
revolving loan funds.119 Funds made available through the STORM Act may be used to assist
homeowners, businesses, certain nonprofit organizations, and communities to reduce risk in order
to decrease the loss of life and property, the cost of flood insurance, and federal disaster

112 Mitigation reconstruction is the construction of an improved, elevated structure that conforms to the latest building
codes on the same site where an existing structure and/or foundation has been partially or completely demolished or
destroyed. See FEMA, HMAPPG, p. 75.
113 Close-out is the end of the grant process, when the award recipient must submit the final financial and programmatic

consisting of grants from the federal government or a state, or private investment. RLFs can make loans targeted to
specific types of borrowers or for specific types of activities, and are designed to use loan repayments to recapitalize
the fund and therefore make additional loans. This may create an ongoing source of funding and potentially reduce the
need for annual appropriations.

payments. The program is intended to provide states with funding that will help them carry out
their own hazard mitigation projects.120 Eligible entities include states and territories, and the
tribal governments that received a major disaster declaration pursuant to Section 401 of the
Stafford Act.121 As a new program with its first funding round in FY2023, the STRLF is not
mentioned in FEMA guidance or regulations.
Flood Mitigation Assistance Grant Program
The Flood Mitigation Assistance (FMA) grant program is another pre-disaster mitigation funding
program operated by FEMA. The FMA program is funded entirely through revenue collected by
the NFIP,122 and FMA grants are only available to communities that participate in the NFIP,123 to
assist in efforts to reduce or eliminate flood damage to buildings and structures insurable under
the NFIP, particularly repetitive loss124 and severe repetitive loss125 properties. There is no
mention of building code requirements for FMA in the National Flood Insurance Act or in FMA
regulations other than NFIP minimum standards.126
Building Resilient Infrastructure and Communities
DRRA Section 1234 amended Section 203 of the Stafford Act—Predisaster Hazard Mitigation127
to allow use of pre-disaster mitigation funding to establish and carry out enforcement activities
and implement the latest version of consensus-based codes.128 Section 1234 also expanded the
criteria to be considered in awarding pre-disaster mitigation funds, including the extent to which
the applicants have adopted hazard-resistant building codes and design standards.129 FEMA
introduced a new program, Building Resilient Infrastructure and Communities (BRIC),130 in
FY2020 to replace the Predisaster Mitigation Grant Program (PDM).131 In each of the first three
years of BRIC, one of FEMA’s main priorities has been to increase funding to applicants that
facilitate the adoption and enforcement of the latest published editions of building codes. As of
June 2023, the majority of states and territories did not qualify for the BRIC building code point
allotment (see Figure 2).

Building Resilience: FEMA’s Building Codes Policies and Considerations for Congress

FEMA intends to increase its emphasis on building code criteria in future BRIC grant cycles.132 In
FY2022, building code-related activities accounted for up to 40 points of the total 100-point
BRIC technical evaluation criteria score.133 Concerns have been expressed that communities in
states without building codes may be at a disadvantage for competitive awards.134 For example, a
community that has adopted the latest codes could be considered noncompliant if it is in a state
that does not meet the BRIC technical evaluation criteria135 for building codes.136 In addition,
concerns have been expressed that BRIC technical criteria recognize resilience efforts narrowly
and give preference to communities with certain mitigation practices, particularly those within
states, territories, and tribes that have adopted recent versions of the ICC codes, while ignoring
other categories of mitigation, like state floodplain management practices that go above NFIP
minimum standards.137 FEMA responded to some of these concerns in the FY2023 Notice of
Funding Opportunity, offering points under the technical criteria for locally adopted building
codes and alternative higher standards, such as additional freeboard.138
For FY2023, FEMA has designated additional Building Codes Plus Up funding for BRIC. An
additional $2 million is available to each state or territory to carry out eligible building code
adoption and enforcement activities, for a total of an additional $112 million. An additional $25
million is available to tribes to carry out eligible building code adoption and enforcement
activities. In both cases this applies to both ICC code- and energy code-related activities.139
BRIC Direct Technical Assistance
FEMA introduced a new form of assistance for the BRIC program, known as non-financial Direct
Technical Assistance (DTA),140 which is intended to help communities build capacity and develop
applications to support underserved populations.141 The establishment, adoption, and enforcement

selected eight communities to receive DTA in FY2020, 20 communities in FY2021, and 46
communities in FY2022.143 FEMA intends to select 80 communities for DTA in FY2023.144
Applications for DTA in FY2022 were oversubscribed, with 109 communities applying.145
National Flood Insurance Program
DRRA Section 1206(a) amended Stafford Act Section 402—General Federal Assistance146 to
allow state and local governments to use general federal assistance funds for the administration
and enforcement of building codes and floodplain management ordinances, including inspections
for substantial damage compliance.147 If a building in an SFHA is determined to be substantially
damaged, it must be brought into compliance with local floodplain management standards. Local
communities can require the building to be rebuilt to current floodplain management
requirements even if the property previously did not need to do so. FEMA does not make a
determination of substantial damage; this is the responsibility of the local government, generally
by a building department official or floodplain manager. Particularly following a major flood,
communities may be required to assess a large number of properties at the same time, and, as a
result, additional resources may be needed. This provision affords an additional source of funding
to support communities in carrying out such activities.
The NFIP Community Rating System (CRS) is a voluntary incentive-based program that rewards
communities for adopting floodplain management practices to a higher standard than the NFIP
minimum standards by providing reduced-cost flood insurance premiums to policyholders in the
community.148 The CRS program, as authorized by law, is intended to incentivize the reduction of
flood and erosion risk, for example through community adoption of hazard-resistant building
codes to exceed the minimum NFIP requirements, as well as the adoption of more effective

Vulnerability Index (SVI) score equal to or greater than 0.6; (3) qualify as an economically disadvantaged rural

FMA within the last five years. The SVI uses United States Census Data to determine the social vulnerability of every
census tract, ranked on 15 social factors. SVI scores range from 0 to 1, with 1 representing the highest level of social
vulnerability. For example, a SVI ranking of 0.6 means that 60% of census tracts in the nation are less vulnerable than
the tract of interest. Category (4) includes communities with disadvantaged populations as referenced in E.O. 14008
that (1) have had multiple major disaster declarations within the past five years; (2) have limited funds; or (3) have

increase a community’s “class” rating in the CRS on a scale of one to ten, with one being the
highest ranking. As CRS ratings increase, residents of the community receive increasing
discounts on their NFIP premiums. FEMA implemented new guidance for the CRS on January 1,
2021, which for the first time includes prerequisites related to building codes. To qualify for class
8 (for which residents receive a 10% discount on their premiums), the community must adopt and
enforce throughout its SFHA at least a one-foot freeboard requirement for all residential buildings
constructed, substantially improved, and/or reconstructed due to substantial damage. The
freeboard standard must be applied to all residential buildings, whether single-family, multi-
family, or manufactured. This prerequisite can be met through the enforcement of local
ordinances or building codes, and/or state building codes.150

Additional FEMA Technical Assistance
FEMA also provides technical expertise to jurisdictions through Mitigation Assessment Teams
(MATs). These teams deploy to areas affected by disasters, analyze structural damage, and
develop recommendations for local construction methods and building code improvements.152
FEMA has recently taken action to broaden its own capacity to promote the adoption,
administration and enforcement of modern building codes, hiring Regional Specialists in Building
Codes in all 10 FEMA Regions.
FEMA: Building Codes Advocacy and Leadership
Since its founding, FEMA has assumed an active role in the development and promotion of
hazard-resistant building codes, including the activities summarized in the sections below.
Research and Development
Several statutes direct FEMA to collaborate with other federal agencies such as the National
Institute of Standards and Technology (NIST) and private code development organizations like
the ICC to develop hazard-resistant building codes and standards.153 Additionally, FEMA has
assumed a leading role in researching the benefits of building codes, and raising awareness about
code adoption and enforcement. In 2011, the agency initiated a four-party study on the value of
avoided disaster-related physical damages attributed to the use of modern building codes.154 The
most recent part of this study was published in November 2020, Building Codes Save.155 The
report concluded that about half of the buildings struck by a disaster after 2000 avoided losses as
a result of accordance with I-Codes for an estimated aggregate saving of $1.6 billion annually.156
The study projected that I-Code savings would increase to $3.2 annually by 2040, for cumulative
savings of $132 billion.157
FEMA has also helped research, promote, and identify financial and technical support for the use
of “nature-based solutions.” Nature-based solutions refer to building methods that integrate
environmental features and processes into the build environment rather than rely on entirely

artificial, “gray” infrastructure (e.g., “green roofs” fitted with planting medium and vegetation
that reduce rain runoff and energy costs).158
Multiagency Coordination
FEMA leads several multiagency efforts to promote the use of hazard-resistant codes across
federal programs and facilities, including the Mitigation Framework Leadership Group
(MitFLG).159 MitFLG was established through Presidential Policy Directive 8, as directed by the
Post-Katrina Emergency Management Reform Act of 2006 (PKEMRA, P.L. 109-295), and
includes representatives from more than 15 federal agencies as well as SLTT government
representatives that collaborate to increase resiliency to hazards in communities across the
country.160 MitFLG’s efforts include the development of a range of guidance, plans, and executive
orders relevant to hazard mitigation, including the 2019 publication of the National Mitigation
Investment Strategy (NIMS).161 NIMS identifies and tries to coordinate state, local, private, and
federal support for mitigation measures and guide implementation. MitFLG reviewed over 100
agency programs that fund construction or repair of facilities to ensure each program requires
adherence to consensus-based codes.162
FEMA is also working to increase federal personnel with expertise in developing and
implementing codes and standards. For example, FEMA’s Building Codes Strategy called for the
creation of building codes specialists in each FEMA region, and FEMA has reported that each
region will have the position filled by the end of FY2023.163
Public Awareness
FEMA has also supported efforts to raise awareness regarding the importance of building codes.
One recent example is the No Codes, No Confidence campaign developed by the nonprofit
consumer advocate Federal Alliance for Safe Homes (FLASH). With financial support from the
Department of Homeland Security, and in partnership with FEMA and ICC, among others, No
Codes, No Confidence developed events, videos, and other materials to inform individuals about
building codes in their own community, and whether their residences are built to modern, hazard-
resistant designs.164
Monitoring Building Code Adoption
FEMA tracks building code adoption status for SLTTs (an effort called Building Code Adoption
Tracking, or BCAT). FEMA tracks state or territory requirements for building code adoption, the
