To build Section 8 housing, you secure Project-Based Voucher commitments from a local Public Housing Authority through its competitive selection process, layer that rental subsidy with Low-Income Housing Tax Credits and other public funding, clear federal environmental and labor requirements, and execute a development agreement with the PHA before any construction begins. The Housing Assistance Payments contract that follows completion locks in rental subsidy for an initial term of up to 20 years, and that guaranteed income is what makes lenders and tax credit investors willing to fund the deal.
What a Project-Based Voucher Actually Gives You
The Project-Based Voucher program, authorized under Section 8(o)(13) of the U.S. Housing Act of 1937, attaches rental assistance to specific units in your building rather than to individual tenants. Each month the PHA pays you the difference between what the tenant owes (generally 30 percent of adjusted income) and the contract rent. That predictable revenue stream is the foundation your capital stack sits on.1eCFR. Part 983 Project-Based Voucher (PBV) Program
Not every unit qualifies for the subsidy. Federal rules cap assisted units at the greater of 25 percent of total units in the project or 25 units. In areas where vouchers are hard to use, the PHA can raise the ceiling to the greater of 25 units or 40 percent. Units serving exclusively elderly households, eligible youth, or residents receiving supportive services do not count against the cap at all, which is why supportive-services partnerships show up in so many PBV deals.2eCFR. 24 CFR 983.54 – Cap on Number of PBV Units in Each Project (Income-Mixing Requirement)
Your tenant projections should also account for the income-targeting rule: at least 75 percent of families admitted to a PHA’s Housing Choice Voucher program each fiscal year must be extremely low-income, meaning household income at or below 30 percent of area median income.3eCFR. 24 CFR 982.201 – Eligibility and Targeting
Winning a PBV Award
You cannot walk into a PHA with a proposal and expect vouchers. PHAs must select projects competitively, through one of two methods. The more common one is a Request for Proposals: the PHA publishes a notice inviting developers to submit plans for PBV housing, and the RFP cannot be written so narrowly that only one site or developer could realistically respond. Alternatively, a PHA may select a project that has already won a competitive award under another government housing or community development program within the past three years, without issuing a separate RFP.4eCFR. 24 CFR 983.51 – Proposal and Project Selection Procedures
Limited exceptions to competition exist. A PHA may noncompetitively select a project where it holds an ownership interest as part of a public housing improvement initiative, or where the project is converting from public housing or another HUD program. Any noncompetitive path has to be disclosed in the PHA’s 5-Year Plan before it is used.5eCFR. 24 CFR Part 983 Subpart B – Selection of PBV Proposals and Projects
Before selecting any proposal, the PHA verifies three thresholds: the property qualifies as eligible housing (new construction, rehabilitation, or existing), it complies with the unit cap, and it passes site selection standards. Knowing these thresholds before you tie up a site saves months.
Building the Capital Stack
No single source funds a Section 8 project. You layer subsidies, each covering a different role.
Low-Income Housing Tax Credits
LIHTC is the largest source of equity for affordable housing in the country. Authorized under Section 42 of the Internal Revenue Code, the credit goes to developers who build or rehabilitate rental housing where a set percentage of units are reserved for households below specified income thresholds. In practice, you sell the credits to investors for upfront equity that funds construction. Credits are calculated as a percentage of the building’s qualified basis and claimed annually over 10 years.6Office of the Law Revision Counsel. 26 USC 42 – Low-Income Housing Credit
LIHTC equity for construction plus PBV rental income for operations is the combination most lenders and investors want to see. Most state housing finance agencies cap developer fees on LIHTC projects at around 15 percent of total development costs, though some states apply lower percentages or per-unit dollar caps.
HOME, CDBG, and State and Local Sources
The HOME Investment Partnerships Program provides formula grants to state and local governments to build, buy, or rehabilitate affordable housing. Participating jurisdictions use HOME funds to expand affordable rental supply.7Office of the Law Revision Counsel. 42 USC 12741 – Authority
Community Development Block Grants offer flexible funding local governments can direct toward housing and related infrastructure. At least 70 percent of CDBG funds must benefit low- and moderate-income persons, so affordable housing fits naturally.8Office of the Law Revision Counsel. 42 USC 5301 – Congressional Findings and Declaration of Purpose
State and local housing finance agencies add below-market loans, bond financing, and soft debt. Conventional private lending fills the last gap, secured by the project’s PBV rental income.
Subsidy Layering Review
When you combine PBV assistance with tax credits, grants, or tax concessions, HUD requires a subsidy layering review before the PHA attaches assistance to the project. The review confirms you are not stacking so much public money that the project receives excessive assistance. The PHA cannot execute the development agreement or HAP contract until HUD or a HUD-approved housing credit agency completes it. If your funding changes between the review and the point at which all units are under a HAP contract (a revised LIHTC allocation, a new grant), you must disclose it, and a second review may be required. Existing housing that already meets HQS and needs no development work is exempt.9eCFR. 24 CFR 983.153 – Development Requirements
Pre-Construction Compliance That Stops Projects
Two federal requirements catch new developers off guard, and either can freeze a project.
NEPA Environmental Review
Every HUD-assisted project completes an environmental review under the National Environmental Policy Act before federal funds are released. The responsible entity, usually the local government or PHA, maintains a written Environmental Review Record covering historic preservation, floodplains, wetlands, endangered species, and air quality, among other laws.10eCFR. Part 58 – Environmental Review Procedures for Entities Assuming HUD Environmental Responsibilities
The rule that catches people: you cannot commit HUD funds or non-HUD funds in a way that limits reasonable alternatives until HUD or the state approves the Request for Release of Funds. Spending on construction before clearance can disqualify the entire project. The review may be a categorical exclusion or a full Environmental Impact Statement, depending on scope and location.
Davis-Bacon Prevailing Wages
Section 12(a) of the U.S. Housing Act of 1937 requires Section 8 contracts to include a provision paying laborers and mechanics wages no less than the prevailing rates in the locality, as determined by the Department of Labor under Davis-Bacon. The threshold applies to construction contracts above $2,000.11Office of the Law Revision Counsel. 40 USC Subchapter IV – Wage Rate Requirements
The trigger is whether the work counts as “development,” which HUD defines as construction or rehabilitation after the proposal selection date. Routine maintenance and one-for-one replacement of worn-out equipment do not trigger Davis-Bacon. Remodeling that changes the nature of units, reconstruction, and substantial upgrades do. On projects of nine or more PBV units, HUD treats any development activity on existing units initiated within 18 months after the HAP contract effective date as covered development requiring prevailing wages. Noncompliance is grounds for terminating the HAP contract, and prevailing wages in many markets sit well above typical construction labor rates, so budget for it early.12Federal Register. Applicability of Davis-Bacon Labor Requirements to Projects Selected as Existing Housing Under the Section 8 Project-Based Voucher Program – Guidance
Uniform Relocation Act
If your project rehabilitates occupied buildings, the Uniform Relocation Assistance and Real Property Acquisition Policies Act applies. You must take reasonable steps to minimize displacement and, where feasible, offer existing tenants a chance to return to a suitable unit in the completed project. Anyone permanently displaced by acquisition, rehabilitation, or demolition receives relocation assistance including moving expenses and replacement housing payments. Tenants who move temporarily during construction are entitled to reimbursement of out-of-pocket expenses and advance written notice. Relocation assistance is an eligible project cost, so build it into your development budget.13eCFR. 24 CFR 882.810 – Displacement, Relocation, and Acquisition
Design and Construction Standards
Several overlapping standards govern how the building must be built. Design around them; do not retrofit.
Fair Housing Act Accessibility
Covered multifamily dwellings first occupied after March 1991 must include specific accessibility features: readily accessible common areas, doorways wide enough for wheelchair passage, an accessible route through each dwelling, accessible light switches and outlets, reinforced bathroom walls for later grab-bar installation, and kitchens and bathrooms with wheelchair maneuverability.14Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing
Section 504 of the Rehabilitation Act
Any program receiving federal financial assistance must comply with Section 504, which imposes accessibility obligations beyond the Fair Housing Act’s design standards and reaches the full range of a project’s operations, not just physical design.15Office of the Law Revision Counsel. 29 USC 794 – Nondiscrimination Under Federal Grants and Programs
Lead-Based Paint
For rehabilitation of housing built before 1978, federal lead-based paint rules apply. The Residential Lead-Based Paint Hazard Reduction Act defines “target housing” as pre-1978 housing, excluding housing for the elderly or persons with disabilities and zero-bedroom units where no children under six reside. Disclosure and hazard reduction can be a substantial line item on older buildings.16Office of the Law Revision Counsel. 42 USC 4851b – Definitions
Housing Quality Standards
Every unit must meet HUD’s Housing Quality Standards before the PHA executes the HAP contract, and continue meeting them for the life of the contract. HQS covers sanitary conditions, heating and cooling, structural integrity, electrical, water supply, and adequate living space. The PHA inspects before the initial lease and at least every two years thereafter. Unresolved deficiencies can lead to abatement of assistance payments for the affected units.17eCFR. 24 CFR Part 982 Subpart I – Dwelling Unit: Housing Quality Standards, Subsidy Standards, Inspection and Maintenance
Energy Efficiency
New construction on HUD-financed projects must meet minimum energy efficiency standards based on the 2021 International Energy Conservation Code and the 2019 ASHRAE 90.1 standard. HUD extended the compliance deadline for Section 8 PBV projects through December 31, 2026, with specific initiation events to be set in further program guidance.18Federal Register. Final Determination: Adoption of Energy Efficiency Standards for New Construction of HUD- and USDA-Financed Housing; Additional Extension of HUD Compliance Dates
The Development Agreement and HAP Contract
New construction and rehabilitation projects use a two-stage contract sequence. Understanding both stages keeps your schedule realistic.
Agreement to Enter Into a HAP Contract
Before any construction begins, the PHA and owner execute a development agreement. You commit to building the units to HQS and all applicable federal requirements; the PHA commits to entering a HAP contract when the work is complete. The agreement describes the site, the number and size of contract units, estimated initial rents, the scope of work, and the completion schedule.19eCFR. 24 CFR 983.154 – Development Agreement
Construction cannot start before the agreement’s effective date, with limited exceptions. For new construction, development begins with excavation or site preparation. For rehabilitation, it begins when physical work on the housing starts. Starting before the agreement is in place violates the program rules.
The HAP Contract
Once the work is complete and units pass HQS inspection, the PHA and owner execute the Housing Assistance Payments contract. The initial term can run up to 20 years per contract unit, with a minimum of one year. Extensions can be negotiated at any time before expiration, each lasting up to 20 years, with the total remaining term never exceeding 40 years at any point.1eCFR. Part 983 Project-Based Voucher (PBV) Program
How Rent Is Set
The rent the PHA pays is not what you ask for. Initial rent to owner is the lowest of three amounts: 110 percent of the applicable fair market rent for the unit’s bedroom size (minus any utility allowance), the reasonable rent as determined by the PHA, or the rent you request. In the development agreement the figure is an estimate; the actual initial rent locks in when the HAP contract begins.20eCFR. 24 CFR 983.301 – Determining the Rent to Owner
After that, contract rents adjust annually using Operating Cost Adjustment Factors that HUD publishes for each state. OCAFs track changes in wages, utilities, and insurance, exclusive of debt service.21Federal Register. Notice of Certain Operating Cost Adjustment Factors for 2026
Filling the Units
Leasing PBV units does not work like a market-rate building. Applicants come from the PBV program waiting list, and the PHA controls its structure. The PHA may keep a single central list covering all PBV projects, combine the PBV list with the tenant-based voucher list, or maintain separate lists for individual projects. If it chooses project-specific lists, it may delegate the list to the owner, but the owner submits a written waiting list policy to the PHA for approval, covering selection procedures, admission preferences, and how the list is opened and closed.22eCFR. 24 CFR 983.251 – How Participants Are Selected
Even where the owner runs the list and picks a family, the PHA makes the final eligibility determination. You cannot offer a unit until the PHA confirms program eligibility.
Living With the Contract
Signing the HAP contract is not the finish. The PHA inspects units at least every two years to verify continued HQS compliance. Deficiencies trigger written notice and correction deadlines; persistent noncompliance can lead to abatement of housing assistance payments, meaning you stop receiving subsidy on the affected units until the problems are fixed.17eCFR. 24 CFR Part 982 Subpart I – Dwelling Unit: Housing Quality Standards, Subsidy Standards, Inspection and Maintenance
Before the contract expires, the PHA decides whether an extension is appropriate to continue providing affordable housing or expand opportunities. Extensions are negotiated between the PHA and owner, up to 20 years per extension, subject to the 40-year total remaining term cap. If the contract expires without an extension, each assisted family can elect to use tenant-based voucher assistance to stay in the project, provided the unit meets HQS and the rent is reasonable.1eCFR. Part 983 Project-Based Voucher (PBV) Program
That last piece matters for long-term planning. If the project-based contract ends and residents convert to tenant-based vouchers, you keep the tenants but lose the guaranteed project-based revenue stream that your original financing was underwritten against. Most owners pursue extensions well before expiration to protect financing stability and preserve value for investors and lenders.
