Financial Incentives for Energy Efficiency Initiatives

Take control of tenant comfort by weatherizing your multifamily property. Air leaks and insufficient insulation contribute to drafts and uncomfortable temperatures. We offer incentives for window retrofits and insulation upgrades to help you improve tenant comfort and reduce energy use. Upgrades are available for owners of electrically heated apartment buildings, condominiums, retirement communities, and/or cooperatives with 5 or more units located in the our service area.

Review our multifamily weatherization incentives and multifamily weatherization program requirements.

If 50% or more of your building tenants are income-qualified, your project may be eligible to participate in City of Seattle Office of Housing HomeWise program which offers incentives up to 90% of project cost.

Commercial building retrofits of lighting fixtures, lighting controls, and HVAC controls can provide excellent energy and cost savings. Multifamily buildings with 5 or more units are eligible for common area upgrades and projects can include multiple energy conservation measures.

Review our commercial retrofit program requirements and commercial retrofit incentive list.

Typical incentives include common area and in-unit lighting, windows and insulation, appliances, whole-house fans, heat recovery ventilators, heat pump water heaters, heat pump dryers, heat pumps for in-unit space heat, Built-Green certification, and custom energy efficiency measures.

We are currently redesigning our new construction offerings for equipment or performance above and beyond what is required by the Seattle Energy Code. Please check back later this year.

We have partnered with distributors to offer instant discounts for qualified lighting, heating, and cooling solutions.
