Federal Buildings & Public Construction — GSA Public Buildings Service

The federal government is the largest property owner in the United States, with over 371,000 buildings and structures encompassing roughly 3.4 billion square feet of space — offices, courthouses, laboratories, data centers, post offices, border stations, military facilities, and more. The General Services Administration's Public Buildings Service (PBS) is the landlord for most civilian federal agencies, responsible for constructing, acquiring, leasing, and managing the space where approximately 1.1 million federal employees work. Under 40 U.S.C. §§ 3301–3315, only the Administrator of GSA may construct or acquire buildings for the government (with limited exceptions for agencies with independent building authority), and any construction or lease project — often involving Buy American Act requirements — exceeding a prospectus-level threshold (currently approximately $3.961 million (FY2026) for construction or $3.961 million (FY2026) annual rent for leases) must receive approval from both the Senate Committee on Environment and Public Works and the House Committee on Transportation and Infrastructure through the submission of a formal prospectus.

Current Law (2026)

Legal Authority

• 40 U.S.C. § 3302 — Prohibition on construction except by Administrator (only the GSA Administrator may construct or acquire buildings for the government, unless another agency has specific statutory authority)
• 40 U.S.C. § 3303 — Continuing investigation and survey (Administrator must continuously investigate and survey federal space needs and develop plans for meeting them)
• 40 U.S.C. § 3304 — Acquisition of buildings and sites (Administrator may acquire buildings and sites by purchase, condemnation, donation, or exchange; buildings must be designed for maximum efficiency and economy)
• 40 U.S.C. § 3305 — Construction and alteration of buildings (Administrator may construct or substantially alter buildings; projects exceeding the prospectus threshold require Congressional committee approval)
• 40 U.S.C. § 3307 — Congressional approval of proposed projects (Administrator must submit a prospectus to Congress for approval before undertaking major construction, alteration, or lease projects; prospectus must describe the project, justify the need, and state the estimated cost)
• 40 U.S.C. § 3308 — Architectural or engineering services (implements the Brooks Act for GSA — selection of architects and engineers must be based on qualifications, not price)
• 40 U.S.C. § 3312 — Compliance with nationally recognized codes (federal buildings must meet building codes, fire codes, and accessibility standards)

Federal Buildings Fund

The Federal Buildings Fund (FBF) — established by 40 USC §§ 581-592 — is a revolving fund that finances the construction, purchase, alteration, and operation of federal civilian buildings managed by GSA. Unlike most federal programs funded by direct appropriations, the FBF operates on a rent-based model: federal tenant agencies pay "rent" to GSA for the space they occupy, and GSA uses those receipts to fund building operations, maintenance, and capital improvements.

How the rent model works: Each federal agency budgets for "rent" as a line item in its annual appropriations request. GSA sets rent rates based on commercial market comparables (typically at or slightly below market rates for equivalent space). In FY2024, the FBF collected approximately $12 billion in rent from federal agencies. This makes GSA one of the largest "landlords" in the United States — managing roughly 370 million square feet of space in 8,400+ owned and leased buildings.

Capital investment discipline: The FBF model creates financial discipline — GSA can only spend what it collects in rent, plus Congressional "spend authorities" that allow it to make capital investments above current receipts (essentially internal borrowing against future rent). New federal building construction projects above a threshold (~$3.961M (FY2026)) require a "prospectus" approved by the House and Senate Public Works committees before GSA can proceed — giving Congress direct oversight of major building investments.

Lease vs. own decisions: GSA manages both owned buildings (paid for through FBF capital investment) and leased buildings (private sector landlords). As of 2024, GSA leases roughly 170 million sq ft — a significant private real estate market; GSA is the nation's largest single tenant. DOGE's 2025 effort to reduce the federal real estate footprint focused on reducing GSA's leased space, which can be terminated with proper notice, before addressing owned buildings.

How It Works

GSA's Public Buildings Service operates through the Federal Buildings Fund (FBF) — a revolving fund that collects rent from tenant agencies at market-comparable rates and uses that revenue to fund building operations, maintenance, construction, and leasing. This self-funding model means PBS operations come from agency rent rather than direct tax appropriations, though Congress controls the FBF through the appropriations process and sometimes redirects building fund revenue to other purposes. For any construction project, major renovation, or lease exceeding the prospectus threshold (~$3.961 million (FY2026)), GSA must submit a prospectus — a formal authorization request describing the project, justifying the need, estimating cost, and explaining alternatives — to the Senate Environment and Public Works Committee and the House Transportation and Infrastructure Committee; both must pass a resolution of approval before GSA can proceed. This requirement gives Congress direct control over major federal building decisions and creates predictable political dynamics around project siting, as legislators actively seek federal facilities for their districts. Federal courthouse construction is a major category of GSA work: the Judicial Conference identifies and prioritizes needs, GSA designs and builds to specialized requirements (courtroom layout, security systems, chambers, detention facilities, and public access), and costs routinely exceed $100 million for major facilities.

GSA is also the government's largest office tenant, leasing approximately 180 million square feet of privately owned space for federal agencies. The leasing program operates through competitive solicitations — GSA issues solicitations for offers describing space requirements, private building owners submit proposals, and GSA evaluates them on price, technical quality, location, and other factors; below the prospectus threshold, GSA has delegated leasing authority to some agencies. All federal buildings must comply with nationally recognized building codes (International Building Code and NFPA codes), accessibility standards (ADA/Section 504), energy efficiency requirements mandated by the Energy Independence and Security Act and executive orders targeting federal building emissions, and Interagency Security Committee physical security criteria. GSA's Facilities Standards for the Public Buildings Service (P100) sets additional design requirements specific to federal construction projects.

Implementing Regulations

• 41 CFR Part 102-71 through 102-85 — GSA Federal Management Regulation (FMR) — facility management, space allocation, building security, design standards, construction management, and real property disposal

• 36 CFR Part 68 — Secretary of the Interior's Standards for Historic Preservation — applies to federal buildings listed on the National Register of Historic Places, governing rehabilitation, restoration, and new construction in historic contexts

• 10 CFR Parts 433–435 — DOE Federal building energy efficiency standards. 10 CFR Part 433 — Energy Efficiency Standards for the Design and Construction of New Federal Commercial and Multi-Family High-Rise Residential Buildings (implementing 42 U.S.C. §§ 6831–6832 under the Energy Conservation Standards for New Buildings Act and EISA 2007): establishes two overlapping requirements for new covered federal buildings. The energy efficiency performance standard (§ 433.100) requires all federal agencies to design new commercial and multi-family high-rise buildings to achieve energy performance at least as good as the ASHRAE Standard 90.1 edition that was in effect when design began — the same benchmark as Part 434 but set as the outer minimum. The Scope 1 fossil fuel-generated energy consumption requirement (§ 433.200), added by EISA 2007, goes further: new EISA-subject federal buildings must achieve a 55% reduction in Scope 1 (on-site fossil fuel combustion) energy consumption relative to a comparable building that just barely meets ASHRAE 90.1 — pushing federal buildings toward electrification and away from on-site natural gas, fuel oil, and coal. Agencies may petition for a downward adjustment (§ 433.202) if the fossil fuel reduction target is technically infeasible for a specific building type. Green building certification (§ 433.300): if an agency chooses a green building certification system (LEED, Green Globes) to demonstrate compliance, the system must meet minimum performance criteria published by DOE — the regulation prevents certification systems with weak energy standards from substituting for the fossil fuel requirements. 10 CFR Part 434 — Energy Code for New Federal Commercial and Multi-Family High Rise Residential Buildings — the mandatory energy performance standard that all federal agencies must meet when constructing new commercial buildings and new multi-family residential buildings of four stories or more, implementing 42 U.S.C. §§ 6831–6832 and 42 U.S.C. § 8253. Key provisions:

  • § 434.4 — Mandatory adoption: federal agencies must design and construct new covered buildings to achieve energy performance at or better than the ASHRAE Standard 90.1 (Energy Standard for Buildings Except Low-Rise Residential Buildings) in effect when design begins; for major renovations costing more than 25% of the building's replacement value, the standard also applies to the renovated portions; the building must achieve the code's performance requirements — there is no waiver for cost or schedule constraints
  • § 434.5 / § 434.6 — Applicability and definitions: "new federal building" means any building constructed for federal use or where the federal government has operational control, including buildings constructed by contractors for government use; "commercial building" means any building other than a low-rise residential building; "major renovation" applies when renovation costs exceed the statutory threshold; temporary structures (less than 3 years' use) and historic structures listed on the National Register may qualify for exceptions
  • §§ 434.100–434.800 — Performance standards by system: the code establishes requirements across eight building system categories: (1) building envelope (insulation R-values, window U-factors, air infiltration limits); (2) lighting and power (lighting power density limits by occupancy type, daylighting controls, occupancy sensors); (3) HVAC and service water heating (minimum equipment efficiency ratings, economizer requirements, ventilation controls); (4) electric power (transformer efficiency, power factor correction); (5) energy monitoring and control systems; (6) individual metering for multi-tenant buildings; (7) life-cycle cost analysis; (8) sustainable design practices. Each category has prescriptive path requirements (specific component standards) and an energy budget alternative path (whole-building energy simulation demonstrating equivalent performance)
  • Life-cycle cost analysis: federal agencies must perform a life-cycle cost analysis for all major energy-consuming building systems — comparing initial capital cost against net present value of energy savings over the building's life; the analysis must use DOD's FEMP-approved analytical tools; the agency must select the design option with the lowest life-cycle cost unless operationally infeasible
  • § 434.600–434.700 — Commissioning and documentation: federal buildings must be commissioning-tested before occupancy — verifying that all energy systems (HVAC, lighting, controls) are installed, calibrated, and operating as designed; commissioning reports are retained as permanent records; post-occupancy energy audits are required within 4 years

  Part 434 was established under the 1988 Federal Buildings Energy Efficiency Standards and has been updated to track ASHRAE 90.1 as the commercial building energy code benchmark. The ASHRAE standard is updated every 3 years; DOE typically adopts new editions into Part 434 on a lagged basis. Federal building energy efficiency requirements also interact with Executive Order 14008 (climate order, 2021) and subsequent executive actions requiring net-zero emissions for new federal buildings by 2045 — Part 434 sets the regulatory floor, while executive orders establish aspirational goals that may exceed it. For federal construction contractors, architects, and engineers: compliance with Part 434 is a procurement requirement embedded in federal construction contracts; failure to meet the standard can result in required costly retrofits post-construction. 10 CFR Part 435 — the complementary rule for new Federal low-rise residential buildings (1–3 stories; typically family housing at military installations and federal housing projects). Part 435 uses the International Energy Conservation Code (IECC) as the benchmark standard rather than ASHRAE 90.1 (the commercial standard in Part 434). New federal low-rise residential buildings must be designed and constructed to achieve energy performance at least as good as the most recently published IECC edition. The "Scope 1 fossil fuel-generated energy consumption" requirement (§ 435.200) implements EISA § 433's mandate to reduce fossil fuel consumption in new federal buildings — federal military family housing, on-base quarters, and federally operated residential facilities must comply. Contractors and architects on federal residential construction projects are required to deliver energy modeling demonstrating IECC compliance with construction documents.

• 10 CFR Part 436 — Federal Energy Management and Planning Programs — the operational companion to Part 434's building code standards, governing how federal agencies manage their existing facilities' energy consumption through analytical methodology, performance contracting, and procurement requirements. Part 436 implements 42 U.S.C. §§ 8253–8259 and 42 U.S.C. § 8287. Key provisions:

  • Subpart A — Life Cycle Cost Analysis Methodology: all federal agencies must use DOE's standardized life-cycle cost (LCC) analysis methodology when evaluating energy efficiency investments in existing federal buildings and systems; LCC analysis compares the total cost of an investment over its useful life (initial cost + operating costs + maintenance costs - salvage value, all discounted to present value) against alternatives; the agency must select the alternative with the lowest life-cycle cost unless there are compelling non-economic reasons to do otherwise; DOE publishes annual discount rates, fuel price projections, and price escalation factors for use in the analysis; the LCC methodology prevents agencies from making short-sighted energy investment decisions based on upfront cost alone
  • Subpart B — Energy Savings Performance Contracts (ESPCs): federal agencies may finance energy efficiency upgrades through Energy Savings Performance Contracts — long-term contracts with private Energy Service Companies (ESCOs) under which the ESCO performs the audit, designs and installs improvements, and guarantees that energy savings will be sufficient to pay back the investment over the contract term (up to 25 years); the agency pays nothing upfront; the ESCO is paid from a portion of the verified energy savings; at contract end, the agency owns the improvements and retains all remaining savings. ESPCs allow cash-strapped agencies to make major building improvements without Congressional appropriations. Key requirements: ESCO must guarantee minimum energy savings; verified measurement and verification (M&V) confirms actual savings; DOE's Federal Energy Management Program (FEMP) pre-qualified list of ESCOs streamlines acquisition; the contract must include a performance period during which the ESCO's payments are contingent on delivering guaranteed savings. The federal ESPC program has delivered $22+ billion in energy projects since 1998, improving energy efficiency in hospitals, military bases, courthouses, and laboratory facilities
  • Subpart C — Agency Procurement of Energy Efficient Products: federal agencies must purchase ENERGY STAR-certified products or products designated by DOE's FEMP as the most energy efficient in their class — this applies to all product categories for which a designation exists (motors, refrigerators, computers, lighting fixtures, HVAC equipment, water heaters); the mandate applies whenever an agency buys, leases, or provides financial assistance for covered product categories; exceptions require documented justification; FEMP publishes updated recommended specifications and product lists annually
  • Subpart F — General Operations Plans: each federal agency must prepare and maintain a 10-year energy management plan setting conservation goals and describing planned measures; annual energy reports submitted to DOE document progress; energy reduction targets are set governmentwide by executive order (currently: 30% energy intensity reduction by 2030 relative to 2015 baseline); agencies that miss targets must explain why and what corrective action is planned

  The federal government is the single largest energy consumer in the U.S., spending approximately $25 billion annually on energy for facilities and vehicles. Part 436's ESPC program is particularly significant because it provides a market-based mechanism to modernize federal facilities without appropriations — ESCOs take on the financing and performance risk, and the government pays only from verified savings. The FEMP technical assistance program provides agencies with tools, training, and expertise to implement Part 436 requirements. Federal energy managers certified through FEMP's training programs are required at major federal installations. The interplay between Part 434 (building code standards for new construction) and Part 436 (energy management in existing buildings) gives DOE comprehensive coverage across the federal facility lifecycle.

No standalone federal buildings reform bills have been introduced in the 119th Congress. Federal construction and property provisions appear in GSA authorization and broader government operations legislation — see Federal Property Management and Government Operations.

Recent Developments

The post-pandemic federal return-to-office debate has significant implications for GSA's building portfolio — with federal telework reducing office occupancy, GSA has been consolidating space and disposing of underutilized buildings. The CARES Act funded COVID-related building modifications (ventilation, spacing). GSA has set ambitious sustainability goals, targeting net-zero emissions for the federal building portfolio by 2045 and prioritizing energy-efficient building design and renovation. The deteriorating condition of many aging federal buildings (the federal deferred maintenance backlog exceeds $40 billion) has prompted calls for increased investment in the Federal Buildings Fund. The GSA leasing program has faced criticism for above-market rent payments and poor space utilization in some markets.
