How to apply for Weatherization Assistance Program — Washington

Who it's for

Washington's Weatherization Assistance Program makes home energy-saving improvements for income-eligible homeowners and renters — insulation, air sealing, and related repairs that lower utility bills. Households qualify with income up to 200% of the federal poverty level, 60% of the state median income, or 80% of the area median income, whichever applies. Apply through the local weatherization agency for the county — the Commerce page lists each county's agency.

What you'll need

• Proof of household income
• Utility bills
• Home ownership documentation (renters: owner's permission)

Where to apply

Step by step

1. Find the local weatherization agency for your county using the Washington State Department of Commerce website — each county has its own agency that handles applications.
2. Gather proof of household income for everyone living in the home, such as pay stubs, benefit letters, or tax documents.
3. Collect recent utility bills for the home you want weatherized.
4. If you own your home, gather your home ownership documentation. If you rent, get written permission from your landlord before applying.
5. Apply online through your local county weatherization agency — the Department of Commerce page lists each agency and its application process.
6. Submit your completed application and all required documents to the local agency for review.

What to expect: After submitting, the local weatherization agency will review your application to confirm income eligibility — eligibility is based on the highest of three published percentage standards (200% of the federal poverty level, 60% of state median income, or 80% of area median income), so check with the agency if you are unsure whether you qualify. If approved, the agency will schedule an energy assessment and any approved improvements, such as insulation, air sealing, or related repairs, as funding allows — processing times and scheduling vary, so ask your local agency for an estimate. This program is a one-time benefit per home, so no annual renewal is needed once work is completed.
