Federal Real Property Profile Public Data Set
Federal real property consists of land, buildings, and structures owned, operated, or leased by the
federal government. Established by the Federal Property and Administrative Services Act of
1949, the General Services Administration (GSA) provides real property services—including the
acquisition, operation, and disposal of buildings and land—to any federal agency that lacks the
authority to do so itself.1 As part of the agency’s real property asset management program, GSA
aggregates data in a number of resources, including the Federal Real Property Profile, to help
agencies better understand the federal inventory.
In Executive Order No. 13327 (effective February 6, 2004), GSA was first directed “to establish
and maintain a single, comprehensive, and descriptive database of al real property under the
custody and control of al executive branch agencies, except when otherwise required for reasons
of national security.” However, under this order the agency was not required to make the data
available to the public.2
In December 2016, Congress passed the Federal Assets Sale and Transfer Act of 2016 (FASTA),
requiring the General Services Administration to “(1) publish a database of al federal real
property under the custody and control of al executive agencies, other than federal real property
excluded for reasons of national security, and (2) make such database available to other federal
agencies and accessible by the public at no cost through GSA’s website.”3
In December 2017, GSA released the first Federal Real Property Profile (FRPP) public data set,
which was an extract of the larger FRPP Management System (FRPP MS) data set for FY2016.
FRPP data are split into two separate public data sets: civilian agencies and Department of
Defense.
Federal Real Property Profile Data for Civilian Agencies
https://www.gsa.gov/policy-regulations/policy/real-property-policy/asset-management/federal-
real-property-profile-frpp/federal-real-property-public-data-set
Each year, federal agencies submit descriptive information on the nature, extent, and use of their
real property assets to GSA to be included in the FRPP MS database. The Federal Real Property
Council (FRPC)4 defines the data elements and technical requirements for data submission and
provides any updates in the FRPC Guidance for Real Property Inventory, also known as the FRPP
data dictionary, available at https://www.gsa.gov/policy-regulations/policy/real-property-policy/
asset-management/federal-real-property-council-frpc/frpc-guidance-library. Criteria for data
submission in the fiscal year of the data set impact the type of information that may be extracted
from the data set.

Following the FRPC guidance, reporting agencies select and submit data to the FRPP MS—
which also means selecting assets to be excluded from the public data set. As such, the public
data set is not as complete as the FRPP MS data set. For example, of the 398,000 assets included
in the FRPP MS database, 305,000 are presented in the public data set for FY2018. The most
recent data available to the public are presented in an Excel spreadsheet available for download at
the website listed above, along with other archived data sets.
Potential Uses of Data
The FRPP public data set is the best source for identifying the federal real property owned or
leased by a specific agency or utilized for a specific purpose within a geographic area. The data
include information on reporting agency, real property type (e.g., building, land, or structure), real
property use (e.g., office, park, or monument/memorial), legal interest indicator (e.g., leased,
owned, or museum trust), addresses, congressional district, and utilization, among other data
points. For a full list of data covered in the spreadsheets and definitions for these categories, see
the FRPP Data Dictionaries available at the Federal Real Property Council Library website linked
above.
The data in the spreadsheets can be sorted and filtered by column to extract various information
of interest to Congress. For example, the Excel columns can be sorted to extract data on
buildings, structures, or land that the federal government owns or leases in a specific district,
county, or state, or the columns can be filtered to view just the properties owned by a specific
federal agency.
Data Limitations and Caveats
In February 2020, the Government Accountability Office (GAO) published a study of the FRPP
public data set titled Federal Real Property: GSA Should Improve Accuracy, Completeness, and
Usefulness of Public Data.5
The GAO study highlighted several limitations of the data, including the following:
 The reported data contain incomplete or inaccurate data, such as incomplete or
incorrectly formatted street addresses.
 GSA and individual reporting agencies withheld information that reduces the
completeness of the public data, such as the bureau within an agency that reports
the data for a property, the entity that uses the asset, and the number of federal
employees working at each property.6
 Agencies withheld publicly available information on some listed assets, and
entirely withheld other assets from the database, while choosing to include
similar assets in an inconsistent manner. For example, the FCC withheld al of its
real property assets despite listing the locations and functions of the FCC offices
on the agency’s own public website.7

Not al categories of data are reported for each property within the spreadsheets. For example,
some properties do not include district or utilization information. Also, the latest real property
data are from FY2018; the status of some properties listed may have changed.
According to the Federal Real Property Council’s 2019 Guidance for Real Property Inventory
Reporting, agencies are also not required to report the following real property data:
 Land easements or rights-of-way held by the federal government.
 Public domain land (including lands withdrawn for military purposes) or land
reserved or dedicated for national forest, national park, or national wildlife refuge
purposes, except for improvements on those lands.
 Land held in trust or restricted-fee status for individual Native Americans or
Native American tribes.
 Land, and interests in land, that are withheld from the database by agency heads
for reasons of national security, foreign policy, or public safety.
 Real property data exempt from public disclosure under FASTA in cases when
the data are already exempt under section 552(b) of the Freedom of Information
Act (FOIA) (5 U.S.C. §552(b)).8
Department of Defense
https://catalog.data.gov/dataset/fy-2017-federal-real-property-profile-data-for-department-of-
defense
The Department of Defense Real Property Profile data are split into five spreadsheets organized
by military branch, including Air Force, Army, Navy, Corps of Engineers, and Department of
Defense Washington Headquarters Service. Due to FASTA’s exclusion of data on properties and
interests in properties for reasons of national security, foreign policy, or public safety, fewer DOD
properties are included in the public data set. Those that are included tend to be more prominent
properties such as bases, airports, naval shipyards, training centers, or proving grounds.
Additional y, the DOD data spreadsheets include fewer data categories than provided for the
civilian agencies. For example, the military branch data include only instal ation name; number of
buildings, structures, or land owned/leased at each instal ation; total square feet; and city/state
where the instal ation is located.
Federal Real Property Map
https://frppmap.gsa.gov/frppmap/
In July 2018, GSA unveiled a GIS-enabled map compiled from the data contained in the FRPP
public data set for civilian agencies that al ows users to view federal real property in an
interactive visual tool. Users can conduct a spatial query (select an area using a shape tool) or
enter address information into a search tool to view the federal real property located in the
geographic area specified.

According to GSA’s 2019 user guide for the FRPP Map, the map also contains eight predefined
views that al ow users to filter results, including the following:
 Disposed View: real property assets disposed during FY2017.
 Excess View: real property declared excess at the end of FY2017.
 Master View: al worldwide real property assets included in the FRPP public data
set.
 Status View: real property assets by status categories.
 Sustainability View: view real property assets by whether or not they have been
evaluated and/or meet criteria for a sustainable federal building.
 U.S. Assets View: real property assets located in the United States.
 Utilization View: real property assets by utilization categories.
 Assets by Congressional District: heat map view of real property assets by
number of assets in each congressional district.9
Users may also filter results from the predefined views above by additional query criteria,
including reporting agency, real property type, and real property use, among other criteria.
In addition to a visual representation of data on a map, users can view results of searches in an
attribute table that provides similar data to the FRPP public data set. Results can be downloaded
from the attribute table into a comma-separated values (CSV) file, but downloads are limited to
2,000 results at a time. For instructions on using the map’s search capabilities, consult GSA’s
Federal Real Property Profile Map User Guide (January 2019), available at https://www.gsa.gov/
cdnstatic/FRPP%20Map%20User%20Guide%20%20January%202019.pdf.
Data Limitations
Because the data for the map are extracted from the FRPP public data set, the same data
limitations previously discussed apply. In the 2020 study of the FRPP public data set, GAO also
found that of the 305,000 assets listed in the public data, approximately 214,000 had some street
address information, and 70,000 of those entries fully met GSA’s standard for complete and
correctly formatted address information. Additional y, GAO noted issues with the accuracy of
geo-coordinates (latitude and longitude) provided for some assets.10 As such, results for a specific
geographic area in the FRPP public data set Excel spreadsheet filtered by city, state, or
congressional district may not always match the results filtered for the same geographic area in
the FRPP map. Also, the FRPP map is slow to load and al ows users to download 2,000 results
from the attributes table at a time; therefore it may be best used for searching/querying smal er
data sets and geographic areas.

Inventory of Owned and Leased Properties
https://www.gsa.gov/tools-overview/buildings-real-estate-etools/inventory-of-gsa-owned-and-
leased-properties
GSA publishes and regularly updates an Inventory of Owned and Leased Properties (IOLP) that is
divided into two categories: owned buildings and leases.
The Owned and Leased Data Sets both include the following data for each listed property:
 Location code, or GSA’s alphanumeric identifier for the building.
 A building’s status as Federal y Owned (F) or Leased (L).
 GSA-assigned region for building location.
 Building address.
 Map coordinates of the building.
 Total rentable square feet in building.
 Square feet of vacant space in building.
 Construction date of building.
 Congressional district where building is located, Senator/Representative of the
congressional district, and their web address.
Also, the Leased Data set includes the following:
 GSA’s alphanumeric identifier for the lease.
 Lease effective date.
 Lease expiration date.
The inventory provides the most up-to-date list of federal y owned or leased real property. It does
not include as much detail as the FRPP public data, such as reporting agency, real property type,
real property use, and utilization. The latest inventory can be accessed and downloaded at
https://catalog.data.gov/dataset/inventory-of-owned-and-leased-properties.
Inventory of Owned and Leased Properties Map
https://www.iolp.gsa.gov/iolp/
GSA maintains an interactive map representing the data in the Inventory of Owned and Leased
Properties, which can be accessed at the web address above. The map provides a visual
representation of the extent of federal real property ownership and leases in a specific geographic
area.
The IOLP map includes four predefined searches, which can be selected from drop-down menus
on the map web page, including the following:
 Property within a Senator or Representative’s jurisdiction (GSA Owned or
Leased).
 Property by state or congressional district (GSA Owned or Leased).
 Lease property search (GSA Leased Only).
 Owned property search (GSA Owned Only).

General Services Administration Lease Inventory
https://www.gsa.gov/real-estate/real-estate-services/leasing-policy-procedures/lease-inventory.
GSA’s lease inventory includes information such as lease number, address, latest action affecting
term of lease (e.g., renewal, new, extension), percentage occupied, annual rent, lessor, and
percentage of space occupied by office, warehouse, or special functions. After the 15th of each
month, GSA posts an updated listing of the inventory to the web page linked above.
Although the inventory is updated more frequently than the FRPP public data and includes lease-
specific information not contained in the FRPP, the lease inventory does not include information
on the leasing agency, property use, property type, or congressional district.
Federal Real Property Summary Reports
https://www.gsa.gov/policy-regulations/policy/real-property-policy/data-collection-and-reports/
frpp-summary-report-library
Prior to the passage of FASTA in 2016 and the subsequent release of the FRPP public data set, the
primary source of real property data available to Congress and the public was the Federal Real
Property Report (FRPR), which provides aggregate data on executive branch agency portfolios.
The report, which is published by the FRPC, draws on information stored in GSA’s FRPP
database. The council establishes data definitions and determines what data to collect and report,
while GSA collects and maintains the data.11
GSA maintains a library of current and archived FRPP Summary Reports, at the website listed
above. The Summary Reports include a data set in the form of an Excel spreadsheet and a
separate Summary of Findings for each fiscal year. The open data set includes data from the past
fiscal year such as statistics on Buildings Real Property Use by Square Footage and Costs,
Utilization of Buildings, Land Acreage and Costs by Agency, Land Dispositions by Method,
Number of Structures and Costs by Agency, Total Land Acreage by State, and other statistics.
Some spreadsheets also include comparison data from the past three fiscal years.
The Summary of Findings provides high-level summaries of data such as national totals of
buildings, structures, and land owned or leased by the federal government, as wel as analytical
comparisons of data from year to year, such as the percentage change in buildings owned by the
federal government or the net proceeds from disposal of real property.
Overal , the data from GSA’s FRPP Summary Reports could be useful in comparing national real
property data against data for a specific geographic region or agency. Because the summary
reports draw data from the FRPP database, the same limitations discussed in the section on the
FRPP public data set apply to the summary reports.
