Insulate Ann Arbor

Helping multifamily properties in Ann Arbor be comfortable, efficient, and healthy.

Rebates for Multifamily Properties

The Ann Arbor Office of Sustainability and Innovations, in partnership with DTE Energy, has launched Insulate Ann Arbor; a rebate program designed to help multifamily rental properties reduce energy use and lower operating costs.

Insulate Ann Arbor offers rebates for insulation and air sealing at multifamily rental properties in Ann Arbor– two of the most cost-effective ways multifamily properties can reduce energy costs and comply with the City’s Green Rental Housing Ordinance. 

Up to $75,000 or 50% of total project costs is available per property, with up to $250,000 or 90% of total project costs available per income-qualified property. Funds are limited and rebate payments are dependent on fund availability.
