Energize - Multifamily Homes Program

Learn how to apply for the Energize - Multifamily Homes Program.

The Energize – Multifamily Homes program provides services and County-managed installations in affordable housing apartments to improve energy efficiency, indoor air quality, and resident comfort, and to lower energy costs. Both subsidized and non-subsidized apartment buildings are encouraged to apply. This program is available to buildings located in King, Kitsap, Pierce, and Snohomish Counties.

 

Applications are now open!

 

Applicants are strongly encouraged to submit their application before January 23rd.

*To apply for this program, you must own or operate a multifamily apartment building serving low-income residents (see eligibility criteria below). If you are a tenant of an apartment building serving low-income residents and think your building may be a good candidate for this program, fill out our tenant referral form!

What does this program provide?

Services provided to program participants may include a combination of the following items:

  • Heat pump installation to provide high efficiency heating and cooling
  • Insulation, air sealing, and ventilation (also known as weatherization) to improve energy efficiency, health, and comfort
  • Heat pump water heaters for low-cost water heating
  • Energy benchmarking to track building energy use; this is aimed at supporting buildings subject to WA Clean Buildings Performance Standards
  • Technical assistance to create decarbonization project plans; financing guidance is also available through King County for buildings receiving this service

Who is eligible?

This competitive program is open to affordable apartment buildings of 5 or more units located in King, Kitsap, Pierce, or Snohomish County. Housing must be considered permanent rental housing to participate in this program. Program services will prioritize frontline communities, defined as buildings located in any of the following geographies:

  • Puget Sound Clean Air Agency overburdened communities 
  • WA Environmental Health Disparities Map score of 9 or more 
  • 2024 U.S. EPA defined low-income and disadvantaged communities  

Generally, these geographies share poorer air and soil quality, higher noise pollution, closer proximity to hazardous waste treatment and storage facilities, and greater risk of related negative health outcomes. Additionally, they experience reduced resiliency to climate change. 

Search your building address on the map at the bottom of this page to see if your property is located in a frontline community geography.

What does "affordable apartment" mean?

Affordable apartment buildings are subsidized or unsubsidized buildings with 5 or more units that have at least 50% of rentable units serving residents earning at or below 80% of County Median Income. King County will perform income verification for all prospective participants prior to issuing final approval for services.

How will my application be reviewed?

How will my application be evaluated?

Applications will be reviewed by King County and scored based on the following categories:

  1. Building Equipment: Replacing fossil fuel-powered equipment is prioritized in this program, especially buildings with fossil fuel space and/or water heating. Fossil fuel energy sources include fuel oil and natural gas.
  2. Building Characteristics: All building sizes are encouraged to apply if they meet, or believe they meet, the eligibility criteria. The benchmarking service may prioritize buildings with a gross floor area (GFA) of greater than 20,000 square feet.
  3. Priority Geographies: The program will prioritize buildings located in frontline communities (please see definition under Who is Eligible).
  4. Climate Preparedness Potential: Geographies most affected by the impacts of climate change may receive priority for program services.

King County reserves the right to select candidates that align with program priorities.

Applications are now open! King County will begin reviewing applications on January 23rd, 2026. We encourage applicants to submit by or before this deadline. King County anticipates closing the application when all available funding has been allocated.
