Section 8 Housing Vouchers: A Complete Guide
The Section 8 Housing Choice Voucher program is the largest federal rental assistance program in the United States, helping approximately 2.3 million households afford housing. The voucher amount is directly tied to HUD Fair Market Rent data, making FMR one of the most consequential numbers in housing policy.
How Housing Choice Vouchers Work
The Housing Choice Voucher program provides a subsidy that covers the gap between what a family can afford (defined as 30% of their adjusted gross income) and the local payment standard. The payment standard is set by local Public Housing Authorities (PHAs) at between 90% and 110% of the Fair Market Rent for the area.
For example, if the 2-bedroom FMR in a county is $1,200 and the PHA sets the payment standard at 100% of FMR, a family earning $24,000 per year would pay $600 per month (30% of gross income divided by 12), and the voucher would cover the remaining $600. The family can choose any unit that meets housing quality standards, as long as the rent is at or below the payment standard.
Look up the FMR in any county to understand voucher payment standards in that area using our county comparison tool.
Eligibility Requirements
Section 8 eligibility is primarily based on income. HUD sets income limits at 50% and 30% of Area Median Income (AMI) for each county, adjusted for family size. At least 75% of new voucher recipients must have incomes at or below 30% of AMI (extremely low income).
Income limits vary dramatically by location. In San Francisco County, the 50% AMI limit for a family of four exceeds $70,000, a figure that would disqualify a family in most rural counties. See our Fair Market Rent guide to understand how HUD determines area median income benchmarks.
Beyond income, applicants must be US citizens or have eligible immigration status, pass a criminal background screening (policies vary by PHA), and provide documentation of income, assets, and family composition.
The Waiting List Problem
The most significant barrier to Section 8 is not eligibility but supply. According to the National Low Income Housing Coalition, only about 1 in 4 eligible households receives any form of federal rental assistance. Waiting lists in major metro areas extend for years, and many PHAs close their lists entirely because demand far outstrips available vouchers.
Wait times vary dramatically, in major metro areas, waits can exceed 5-10 years, while some rural housing authorities have shorter queues.
Finding Housing with a Voucher
Once approved, voucher holders typically have 60-120 days to find a unit. The unit must pass a Housing Quality Standards (HQS) inspection and the landlord must agree to participate in the program. In tight rental markets, finding a willing landlord can be challenging, particularly where FMR is below actual market rents.
Voucher holders can use their voucher anywhere in the country through a process called "portability." This allows families to move to areas with better schools, safer neighborhoods, or more job opportunities. However, the payment standard changes to match the new area's FMR, which can increase or decrease the subsidy.
How FMR Directly Affects Your Voucher
Because the payment standard is derived from FMR, changes in Fair Market Rent directly affect how much housing a voucher holder can afford. When HUD increases FMR in an area, PHAs may increase payment standards, giving voucher holders access to more units. When FMR decreases, voucher holders may face reduced subsidies.

Frequently Asked Questions
Section 8 Housing Choice Vouchers cover the difference between 30% of your adjusted gross income and the payment standard, which is typically set between 90-110% of Fair Market Rent. For example, if the payment standard is $1,200 and your income-based share is $400, the voucher covers $800.
To qualify for Section 8, your household income must be below 50% of the Area Median Income (AMI) for your county. Priority is given to families at or below 30% AMI (extremely low income). Eligibility also considers family size, citizenship status, and criminal background depending on the local housing authority.
Section 8 waiting lists vary dramatically by location. In high-demand areas like New York and Los Angeles, waits can exceed 5-10 years. In some rural areas, the wait may be under 1 year. Many housing authorities close their waiting lists entirely due to overwhelming demand.
In some states and cities, landlords cannot legally refuse Section 8 voucher holders, this is called source of income discrimination protection. However, in states without such protections, landlords can decline to participate in the voucher program. Currently about 15 states and many large cities prohibit source of income discrimination.
