A plain-language guide

How affordable housing actually works in Seattle.

It's confusing — there's no single phone number to call or office to visit. But that's also good news: there are several different programs, each designed for different situations. This guide walks you through them in plain English so you can figure out which ones apply to you.

Reading time: about 6 minutes.

The three main paths

Almost every affordable apartment in Seattle falls into one of these three categories. They overlap sometimes — a single building can be both a tax-credit property and accept your voucher.

1. Project-Based Subsidized

Apply at the building

The government pays part of your rent — but the subsidy stays with the building. If you move out, the help stays put.

  • Rent is capped at about 30% of your monthly income.
  • Funded by HUD or USDA. The owner has a contract to keep rents affordable.
  • Apply directly at the property's leasing office.
  • Income limits apply — usually under 50% of Area Median Income (AMI).
Example: a 1-bedroom that rents at market for $2,200 might cost you $450/mo if you earn $1,500/mo.

2. Tax Credit / Bond Apartments (LIHTC)

Apply at the building

Privately-owned apartments with rents kept below market because the owner gets state tax breaks in exchange.

  • No personal subsidy — but rent is set well below market.
  • Income limits apply (usually 30%, 50%, 60%, or 80% of AMI tiers).
  • Apply directly at the property.
  • Most accept Housing Choice Vouchers if you have one.
Example: a 60% AMI 1-bedroom might be $1,400/mo when the open market would charge $2,200, no income subsidy needed.

3. Public Housing & Vouchers (Section 8)

Apply with Seattle Housing Authority

Either move into a building SHA owns (public housing) or get a portable voucher you can use at most apartments.

  • Apply at SHA — both lists are open year-round.
  • Public housing: SHA owns the building. Rent is ~30% of income.
  • Voucher (Section 8): you find your own apartment, voucher pays the difference between fair-market rent and 30% of your income.
  • Vouchers are portable — they go with you when you move.
Example: with a voucher, you find a $2,000/mo apartment that accepts vouchers. If you earn $1,500/mo, you pay $450 (30%) and the voucher covers the rest.

Other paths to know about

Beyond the three big categories, there are specialized programs designed for specific situations.

Permanent Supportive Housing (PSH)

Long-term apartments paired with on-site case management, designed for people exiting homelessness or with disabilities.

Usually no time limit. Wraparound services (case manager, mental health, addiction treatment) are part of the deal. Referral typically goes through the King County Regional Homelessness Authority — you don't apply directly.

Rapid Re-Housing

Short-term help (3–24 months) with rent and move-in costs to bridge a crisis back to stability.

Aimed at households who became homeless recently and just need a runway. Your case manager finds the apartment and the program pays a declining share of rent until you can take over.

Emergency Shelter & Transitional Housing

Immediate beds, day-to-day or 30–90 days at a time, often as a step toward permanent housing.

Connect through the King County Regional Homelessness Authority (regionalhomelessauthority.org/find-services). Some programs are family-specific; others serve youth, veterans, or domestic-violence survivors.

Senior & Disability-Specific (HUD 202 / 811)

Buildings reserved for seniors 62+ (HUD 202) or people with disabilities (HUD 811). Rent ~30% of income.

Smaller pool than mainstream subsidized housing but specifically designed for the population — accessibility features and supportive services are usually built in.

Where do I start?

Pick the situation closest to yours.

If…

I'm currently unhoused or in shelter

Start with PSH and rapid re-housing — these programs prioritize unhoused households. Connect through the King County Regional Homelessness Authority for an assessment and referral.

If…

I already have a Housing Choice Voucher

Browse buildings that accept vouchers — most tax-credit properties do. Filter our listings by 'accepts vouchers' to narrow the list.

Browse voucher-friendly listings

If…

My income is low but I'm currently housed and stable

Apply at multiple project-based and tax-credit buildings simultaneously. Also get on the Seattle Housing Authority waitlist — both public housing and vouchers — even if the wait is years. There's no penalty for waiting.

If…

I'm a senior (62+) or have a disability

HUD 202 and 811 buildings are specifically for you. Many other affordable buildings also have set-aside units. Use our accessibility filter on listings to find buildings with ADA units.

Plain-English glossary

The acronyms and jargon you'll keep running into.

AMI (Area Median Income)
The middle income for a household of your size in your county. HUD updates the numbers every April. Income-restricted apartments are usually labeled by AMI tier (30%, 50%, 60%, 80%).
In King County (2024), 50% AMI for a household of 2 is about $54,800/year. So a '50% AMI' apartment is open to a 2-person household earning up to that.
30% of income (rule of thumb)
Many subsidies cap your rent at 30% of your gross monthly income. Below that line, housing is considered affordable.
If you earn $1,500/month, your rent in a subsidized building would be capped at about $450/month.
Housing Choice Voucher (Section 8)
A portable subsidy you take to any apartment whose owner accepts vouchers. The voucher pays the difference between fair-market rent and 30% of your income.
You find a $2,000/mo apartment. You earn $1,500/mo. You pay $450 (30%); the voucher covers $1,550.
Project-Based vs. Tenant-Based
Project-based subsidies stay with the building when you move out. Tenant-based subsidies (vouchers) go with you.
Waitlist
A queue of households waiting for a unit to open up. Some lists are years long; some are closed entirely. Many use random selection rather than first-come-first-served.
PHA (Public Housing Agency)
The local agency that runs public housing and vouchers. In Seattle, that's the Seattle Housing Authority (SHA). Outside Seattle in King County, it's the King County Housing Authority (KCHA).
LIHTC (Low-Income Housing Tax Credit)
A federal tax credit for property owners who keep rents below market for low-income households. Most 'affordable apartments' you see in Seattle are LIHTC properties.
