Section 8 and HUD eligibility, explained

Eligibility for HUD-assisted housing comes down to a handful of factors: income, household composition, citizenship or eligible immigration status, and — for some programs — additional criteria such as age or disability. The exact rules vary slightly by program and are administered locally, but the framework below holds for almost every property listed on Rent Affordable.

1. Income

Your household's income must fall under a published threshold for your county and household size. HUD recalculates these limits every year. There are three commonly-used tiers:

Extremely low income — at or below 30% of Area Median Income (AMI) or the federal poverty line, whichever is greater.
Very low income — at or below 50% of AMI. Most project-based Section 8 households fall here.
Low income — at or below 80% of AMI. Some HUD programs allow this ceiling, but project-based Section 8 typically does not.

By federal rule, at least 75% of new admissions to Housing Choice Voucher and Project-Based Section 8 programs each year must come from households at or below 30% AMI.

2. Household composition

HUD counts every person who will live in the unit as a household member, including children, elderly parents, and live-in aides. Your household size determines both the income limit you compare against and the number of bedrooms you qualify for. Many properties follow occupancy guidelines like "two persons per bedroom" with adjustments for age and gender.

3. Citizenship or eligible immigration status

At least one member of the household must be a U.S. citizen or hold an eligible immigration status (such as Lawful Permanent Resident or refugee). Mixed-status households can still receive prorated assistance — only the eligible members count toward the subsidy calculation. You will be asked to declare status on the application; declaring honestly is critical.

4. Background and screening

Federal law requires PHAs and property owners to deny assistance to anyone subject to lifetime sex-offender registration, anyone convicted of producing methamphetamine in federally-assisted housing, and certain other categories. Beyond those federal bars, individual properties may run criminal-background, credit, and rental-history checks. Each property publishes its own screening criteria — ask before you apply if you have concerns.

5. Program-specific criteria

Section 202 — household head, spouse, or sole member must be 62 or older.
Section 811 — household must include at least one adult with a qualifying disability.
Project-Based Section 8 — varies by contract; some are designated for elderly, family, or special-needs populations.

How rent is calculated

Once you're admitted, your monthly rent is generally the greatest of:

30% of your monthly adjusted income, or
10% of your monthly gross income, or
The "minimum rent" set by your local PHA (commonly $25–$50).

"Adjusted income" subtracts deductions for dependents, elderly or disabled household members, child care, medical expenses, and certain other items. The federal subsidy makes up the difference between your share and the property's contract rent.

How to confirm your numbers

You can look up your local AMI and income limits on HUD User's Income Limits page (search "HUD income limits" plus your county and year). When you apply at a property listed on Rent Affordable, the on-site management can confirm the exact limits in effect for your area and household size.
