Section 8 vs. Project-Based Vouchers: Key Differences
Meta description: Compare Section 8 Housing Choice Vouchers and project-based vouchers, including where the subsidy stays, how moving works, rent rules, and how to apply.
“Section 8” is often used as if it describes one type of housing assistance, but it includes programs with different rules. A Housing Choice Voucher (HCV) generally lets a household rent an eligible home in the private market, while a project-based voucher (PBV) is attached to a particular apartment. Both are part of the federal Section 8 program and can help eligible households afford rent. The main difference is whether assistance follows the household or stays with the unit.
What “Section 8” Means
Section 8 refers to federal rental assistance authorized under Section 8 of the U.S. Housing Act. The U.S. Department of Housing and Urban Development (HUD) funds the programs, and local public housing agencies (PHAs) administer much of the assistance. A PHA may be called a housing authority.
Two programs commonly compared under the Section 8 label are the Housing Choice Voucher program and the Project-Based Voucher program. The names can be confusing: a PBV is not separate from Section 8. It is one form of Section 8 assistance. Another program, Project-Based Rental Assistance (PBRA), also provides subsidies tied to properties but has different rules and contracts.
In both HCV and PBV programs, the household generally pays a portion of its income toward rent, and the subsidy helps cover the approved amount above that contribution. Eligibility, rent limits, available units, and administrative procedures depend on federal rules and the local PHA.
Housing Choice Vouchers: Assistance Generally Follows the Household
A Housing Choice Voucher is commonly called a tenant-based voucher because the assistance is issued to an eligible household rather than permanently assigned to one apartment. The household searches for a rental home that meets program requirements, and the PHA evaluates the proposed unit and rent before assistance begins.
Depending on local program rules and the landlord’s participation, an HCV may be used in an apartment, a townhouse, a single-family home, or another eligible rental. The unit must pass applicable housing-quality requirements, and the rent must be approved as reasonable under program rules. The landlord must agree to participate and sign the required contract with the PHA.
Because the voucher is tenant-based, the household may be able to move to another eligible unit while keeping assistance, provided it follows notice and program procedures. In many cases, voucher holders can also use “portability” to move to a different PHA’s jurisdiction. Portability is not an automatic right to move at any time: the household must meet applicable requirements, coordinate with the PHAs, and find an approved unit. Initial residency rules may also apply.
Project-Based Vouchers: Assistance Is Tied to an Apartment
A project-based voucher is assigned to a specific unit in a property covered by a contract between the PHA and the property owner. The household receives assistance while it lives in that designated unit and meets program requirements. If the household moves out, the subsidy generally remains with the apartment for the next eligible household, rather than traveling with the departing resident.
PBV apartments may be located in privately owned buildings, including properties developed or renovated with affordable-housing financing. The PHA selects units and contracts with owners to provide assistance. A property may have PBV apartments alongside units that are not subsidized, so not every resident in a building necessarily receives the same type of assistance.
In general, a resident who leaves a PBV unit does not take the project-based subsidy to a different apartment. Federal rules provide a pathway to request tenant-based assistance after a year of PBV assistance, but access depends on the applicable rules and voucher availability. If tenant-based assistance is not immediately available, the household may need to remain on a waiting list or continue following the PHA’s procedures.
Section 8 vs. Project-Based Vouchers at a Glance
| Feature | Housing Choice Voucher | Project-Based Voucher |
|---|---|---|
| Common name | Tenant-based voucher or HCV | PBV or project-based voucher |
| Where assistance is attached | Generally follows the household | Stays with a designated unit |
| How a home is selected | Household searches for an eligible rental | Household applies for an available PBV unit |
| Moving to another home | Often possible with PHA approval and required procedures | Assistance generally does not transfer with the household |
| Portability between jurisdictions | May be available under HCV portability rules | Not through the PBV subsidy itself; a household may later qualify for tenant-based assistance |
| Landlord participation | Landlord must accept the voucher and meet program requirements | Owner has a contract with the PHA for designated units |
| Availability | Depends on the local HCV waiting list and funding | Depends on PBV properties, unit turnover, and local application procedures |
How Rent and the Subsidy Are Determined
Both programs generally require residents to contribute a share of their income toward rent and utilities. In many cases, the family’s required contribution is calculated using adjusted income, with rules that account for certain deductions and circumstances. It is not always exactly 30% of take-home pay. Federal regulations set the calculation framework, while the PHA applies the rules to the household’s circumstances.
For an HCV, the PHA uses a payment standard to determine the maximum subsidy calculation for the household’s voucher size and area. The approved rent, utility allowance, household contribution, and payment standard all affect the final amount. A household may sometimes choose a unit with rent above the payment standard, but it generally must pay the difference, and limits apply to the amount it can pay at initial lease-up.
For a PBV unit, the rent must comply with applicable program limits and the PHA-owner contract. The household’s contribution is calculated under program rules, and the PHA pays the covered subsidy to the owner. The exact rent and utility arrangements can vary by unit and lease, so applicants should ask the property or housing authority for a written estimate before signing.
Important: Neither program guarantees that every advertised rent will be approved. The PHA must review the proposed tenancy and rent, and the unit must satisfy applicable requirements. A household should not assume that a voucher will cover a particular apartment until the PHA confirms approval.
Eligibility, Waiting Lists, and Applying
Eligibility for HCV and PBV assistance is based on factors such as household income, family size, citizenship or eligible immigration status, and other federal and local rules. Income limits vary by area and household size. PHAs may also apply preferences, such as preferences for people experiencing homelessness or living in substandard housing, when permitted by their policies.
HCV and PBV waiting lists may be separate. A PHA might accept applications for one program but not the other, and some PBV properties may have their own application process or waitlist managed by the owner or PHA. An open waiting list does not guarantee a prompt offer: wait times depend on funding, turnover, application volume, and local selection policies.
- Find the administering PHA. HUD’s PHA directory can help locate housing authorities by state or city.
- Check which lists are open. Ask whether the agency accepts HCV applications, PBV applications, or both.
- Review local preferences and documents. Application requirements may include income, household, identity, and eligibility information.
- Keep contact details current. A missed notice or outdated address can affect an application’s status.
- Confirm the type of assistance offered. Ask whether an offer is tenant-based or tied to a specific PBV unit.
Applications should be made through the relevant PHA or authorized property contact. Applicants should be cautious about anyone charging a fee to secure a place on a government housing voucher waiting list. Official agencies provide instructions on legitimate application steps.
What Happens If a Household Wants to Move?
Moving With a Housing Choice Voucher
An HCV household can generally request to move, but it must follow its lease, provide required notice, and coordinate with the PHA. The next home must meet program standards, and the rent and landlord must be approved. A move to another jurisdiction may involve portability procedures and communication between the current and receiving PHAs.
Moving may affect the household’s share of rent or the amount of assistance. A different home may have a different rent, utility cost, payment standard, or bedroom size. The PHA can explain how those factors apply before the household commits to a new lease.
Moving From a Project-Based Voucher Unit
A household leaving a PBV apartment usually gives up the subsidy attached to that unit. Federal regulations generally allow a family that has received PBV assistance for at least one year to request tenant-based assistance. The PHA must handle the request under applicable rules; whether a voucher can be issued right away depends on availability and program administration. Residents should ask the PHA about the process well before planning a move.
Some PBV residents may be able to move to another assisted unit in the same property, but that depends on available units, the PHA’s contract, and program rules. A move to a different property does not ordinarily transfer the original unit’s PBV subsidy to the new home.
Advantages and Trade-Offs
HCVs offer more housing choice. A household can search across eligible private-market rentals and, when allowed, may move while retaining tenant-based assistance. That flexibility can help with a job change, family needs, or a move to another area. The trade-off is that finding a landlord, an affordable unit, and a home that passes program review can take time.
PBVs can connect assistance to a specific affordable unit. Applicants may have access to housing in a property with contracted assistance, and the search for a participating landlord is not the same as with an HCV. The limitation is reduced mobility: the subsidy generally stays with the apartment, and moving may mean losing that particular assistance unless tenant-based assistance becomes available.
Neither option is universally better. The practical choice depends on the household’s priorities, available housing, local waitlists, and the rules of the administering PHA. In some places, a PBV unit may become available sooner than an HCV; elsewhere, the opposite may be true. Availability is local and changes over time.
Common Misunderstandings
- “Section 8” always means a portable voucher. Not necessarily. The term can refer to multiple kinds of assistance, including PBVs.
- A PBV resident can take the subsidy to any apartment. Usually not. The subsidy is attached to a designated unit, although a tenant-based assistance request may be possible under federal rules.
- A landlord must accept every HCV. Federal program participation requires the landlord’s cooperation, and state or local laws on source-of-income discrimination vary. Local protections may apply.
- A voucher pays the full rent. Typically, the household pays a calculated portion, while the subsidy covers an approved amount subject to program limits.
- Every apartment in a PBV building is subsidized. Only designated units are covered by the project-based contract.
Where to Verify Program Rules
Because local procedures and availability differ, applicants and residents should confirm details directly with the administering PHA. Useful questions include whether a waiting list is open, how rent is calculated, which units are covered, what moving rules apply, and whether tenant-based assistance may be requested after living in a PBV unit.
Authoritative information is available from HUD’s housing resources, the HUD Public Housing Agency directory, and federal regulations for the Housing Choice Voucher program and Project-Based Voucher program. These sources can help distinguish general federal rules from policies that vary by PHA.
