Section 8, officially called the Housing Choice Voucher program, helps low-income families, seniors and people with disabilities rent a home from a private landlord. You usually pay about 30% of your adjusted monthly income toward rent and utilities, and your local public housing agency (PHA) pays the rest, up to a limit, straight to the landlord. You apply through a PHA, applying is free, and waiting lists are common.
The program is funded by the U.S. Department of Housing and Urban Development (HUD) and run by local public housing agencies. According to HUD's page for voucher tenants, you can use a voucher to rent a house, townhouse or apartment in the private market, as long as the unit passes inspection and the rent is approved.
HUD's tenant page lists these basic requirements:
Under the federal rule (24 CFR 982.201), most applicants must be "very low income," which 24 CFR 5.603 defines as income at or below 50% of the median family income for the area. The same rule requires that at least 75% of the families a PHA admits from its waiting list each year be "extremely low income," so the lowest-income applicants make up most new admissions.
There is no single national income limit. HUD sets limits for each area and family size, and the FY2026 limits took effect May 1, 2026. Here is one example from HUD's data:
FY2026 income limits for the Phoenix-Mesa-Chandler, AZ area (Maricopa and Pinal counties):
| Family size | Very low income (50%) | Extremely low income |
|---|---|---|
| 1 person | $39,350 | $23,600 |
| 2 people | $45,000 | $27,000 |
| 3 people | $50,600 | $30,350 |
| 4 people | $56,200 | $33,700 |
These numbers apply only to the Phoenix area. Look up your own county with HUD's income limits tool, and see our guide to Section 8 income eligibility for how income is counted. Your PHA makes the final decision on whether you qualify.
Three numbers decide how much you pay and how much the PHA pays.
Your share is called the total tenant payment. Under 24 CFR 5.628, it is the highest of 30% of your monthly adjusted income, 10% of your monthly gross income, a welfare rent in some cases, or the PHA's minimum rent. Adjusted income is your income after deductions the rules allow, such as for dependents, child care, and some medical costs for elderly or disabled families.
The payment standard is the most the PHA will pay toward rent and utilities for your voucher size. Each PHA sets its own, usually between 90% and 110% of HUD's Fair Market Rent for the area (24 CFR 982.503). HUD publishes Fair Market Rents every year, generally effective October 1.
The gross rent is the landlord's rent plus any utilities you pay yourself.
The PHA's payment, called the housing assistance payment, is the lower of the payment standard minus your share, or the gross rent minus your share (24 CFR 982.505). The PHA sends that money directly to the landlord, and you pay the landlord the rest.
Say your adjusted monthly income is $1,500, so 30% is $450, and your PHA's payment standard for your voucher size is $1,600.
There is a cap on that second situation. When you first move into a unit that costs more than the payment standard, your share cannot be more than 40% of your monthly adjusted income (24 CFR 982.508). In the example, 40% of $1,500 is $600, so a $550 share is allowed. The PHA will not approve a unit that would push you over the cap.
Applying and getting on a waiting list cost nothing. HUD's Office of Inspector General warns that "housing authorities and government agencies will never ask you to pay for admission to housing assistance programs or to join a waitlist" (HUD OIG fraud bulletin, August 1, 2024). Scammers post fake waitlist openings on social media. Check with your PHA at the phone number on its official website, and report scams to the HUD OIG Hotline at 1-800-347-3735.
Once you have a voucher, these are your costs:
Most of the wait happens before you get a voucher. USA.gov says waiting lists and long waits are common because HUD and PHAs have limited funds, and PHAs may close their lists when they get too many applications. HUD's tenant page says only that waits can be lengthy, so ask your PHA how long its list is.
Here is the usual order of events:
If your application is denied, the PHA must send you a notice that gives the reason and explains how to request an informal review (24 CFR 982.554). HUD says you typically have 10 to 14 days to ask in writing, so check the deadline in your letter right away. Free legal aid programs listed at LawHelp.org can help you prepare.
HUD's tenant page and 24 CFR 982.551 set out what you must do to keep your assistance:
The PHA verifies income with third-party sources at each review, so a new job or raise that goes unreported can come to light later and put your voucher at risk.
Vouchers can move with you. If you lived outside the PHA's area when you applied, you may have to rent in that area for the first 12 months. After that, you can generally move anywhere in the U.S. that has a voucher program, after you give proper notice. Our guide to transferring a Section 8 voucher to another state covers the process.
Some PHAs also let voucher holders put the assistance toward buying a home. PHAs don't have to offer this. According to HUD's homeownership program page, you must be a first-time homeowner, meet minimum income requirements and complete counseling with a HUD-approved housing counseling agency. Ask your PHA whether it takes part.
Yes. Housing Choice Voucher is the official name of the Section 8 voucher program. HUD also runs Section 8 project-based programs, which are tied to specific buildings, so ask which kind a property or waitlist is for.
Usually not. Most people pay about 30% of their adjusted monthly income. If your income is very low or zero, your share may be the PHA's minimum rent, which can be up to $50 a month, and you can ask for a hardship exemption if you cannot pay it.
It depends on where you live. HUD notes that some communities prohibit landlords from discriminating against voucher holders, so check your state and city rules or ask your PHA.
Yes. HUD says you can apply to more than one PHA and don't have to live in the area to apply. If you are approved by a PHA where you did not live when you applied, you may need to rent there for the first 12 months.
Call the housing agency at the number on its official website or find it in HUD's PHA directory. Real PHAs never charge to apply or to join a waitlist. Don't give your Social Security number or birth date in reply to a social media ad.
