Your application paperwork

This is a free, federally funded program that lowers your energy bills by improving your home's energy efficiency. After you qualify (up to 200 percent of the federal poverty level, 60 percent of state median income, or 80 percent of area median income), a local agency does a free energy audit and installs measures at no cost. The Washington State Department of Commerce runs it through local weatherization agencies, so you apply through the agency that serves your area.

Steps to apply

  1. Confirm you qualify by income (up to 200 percent FPL, 60 percent SMI, or 80 percent AMI) and that you own or rent the home.
  2. Find and contact the local weatherization agency that serves your county (Commerce does not take applications directly).
  3. Complete the agency's intake application with your income, ownership, and household information.
  4. The agency does a free energy audit, then installs the approved measures at no cost to you.

Documents you will likely need

  • Proof you own or rent and live in the home (renters need the owner's written permission).
  • A recent utility bill for the home.
  • A government-issued photo ID.
