Section 8 Tenant Qualification Rules and Income Limits Explained

Section 8 eligibility is determined by the local Public Housing Agency using income limits published annually by HUD — not by the landlord. Still, understanding how the qualification process works helps you make sense of what a voucher actually represents, and where your responsibilities as a landlord start and stop.

How HUD income limits work

Each year, HUD publishes income limits for every county and metro area in the country, expressed as a percentage of that area's median family income (AMI) and scaled by household size. The three thresholds that matter for Section 8 are Extremely Low Income (30% of AMI), Very Low Income (50% of AMI), and Low Income (80% of AMI). By federal rule, at least 75% of the vouchers a PHA issues each year must go to Extremely Low Income households — the program is specifically targeted at the lowest-income renters, not just anyone under the Low Income threshold.

How a household actually qualifies

An applicant applies directly to their local PHA, not to a landlord or to HUD centrally. The PHA verifies the household's income against the current limits for their area and household size, checks citizenship/immigration status requirements, and runs the household through the PHA's own screening (some PHAs also screen for criminal history or prior program violations, separate from whatever screening a landlord later runs). Approved applicants are placed on a waitlist — often a long one, since demand for vouchers substantially exceeds the supply funded by Congress in most areas — and issued a voucher once one becomes available.

The 30% rule

Once issued a voucher, a household generally pays about 30% of its monthly adjusted income toward rent and utilities, with the voucher covering the difference up to the PHA's payment standard for that unit size. "Adjusted income" accounts for certain deductions (medical expenses, childcare, and a few others), so it's not simply 30% of gross income — the PHA calculates this precisely during the household's annual recertification.

What a landlord should verify — and what's not your job

As a landlord, you're not the one determining eligibility, verifying income against HUD limits, or managing the waitlist — that's entirely the PHA's role. What you should verify directly is that the voucher is current and valid (vouchers have an expiration window, typically 60-120 days from issuance, within which the holder has to find a unit), and that the voucher's authorized bedroom size is compatible with your unit. Beyond that, your screening (credit, background, references) proceeds exactly as it would with any applicant — the voucher itself already represents that HUD's income determination has been made.

Where to find real numbers for your area

Because income limits vary by county and change annually, don't rely on a rule of thumb or an outdated figure. HUD publishes the current, official numbers by area at huduser.gov/portal/datasets/il.html, and your local PHA can also confirm the specific limits and payment standards in effect for your property's location.
