Seattle's HomeWise Weatherization Program offers no-cost energy-efficiency improvements to eligible households, including insulation, air sealing, heating-system work, ventilation and certain appliance replacements after an assessment.

Why it matters. A drafty home can raise winter bills while making rooms uncomfortable. In older Beacon Hill houses and Rainier Valley rental buildings, the issue may be the building envelope or equipment rather than simply the thermostat setting.

On the ground. The program serves eligible homeowners and renters within Seattle and certain Seattle City Light customers outside city limits. Renters in small buildings may need to coordinate with owners; eligibility depends on income, heating source and housing arrangement.

Step 1. Record the home's heating source, utility account information and where heat loss or moisture appears.

Step 2. Review HomeWise income limits and documentation before applying; eligible applicants are contacted for a professional energy audit.

Step 3. If you rent, ask about the program's multifamily rules and coordinate with your landlord rather than commissioning unauthorized improvements.

Before acting. An application does not promise every upgrade. Program staff determine eligible work after review and assessment, and processing time varies. Do not pay a contractor who claims to guarantee a HomeWise award.

Weatherization and bill discounts solve different problems. A discount reduces an eligible bill while the household remains enrolled; insulation and air sealing can reduce the amount of energy a building needs. Some households may need both kinds of assistance.

Before an assessment, note whether cold rooms, condensation, drafts or aging equipment are the main concern. A dated record helps explain the problem, but it is the program's specialist who decides which work is suitable and funded.

Renters should keep the discussion practical and documented. Ask the property owner about permission and access, explain that HomeWise manages qualified contractors, and avoid paying deposits to someone claiming to represent the program without verifying directly with Seattle's Office of Housing.
