Multifamily ceiling insulation bonus incentive now available

Energy Trust is offering a limited time ceiling insulation bonus incentive for all qualifying small multifamily properties, which include duplexes, triplexes, fourplexes and side-by-side units. The bonus is available for qualifying projects where the material is purchased and installed between June 1 – October 31.  

During the bonus period, the total incentive for multifamily properties will be $1.25/sq ft per qualifying project, making this a $1.00/sq ft bonus on top of the standard $0.25/sq ft incentive. This limited time incentive is only available in Oregon and will align with incentives for single-family rental property programs and the Savings Within Reach program. 


  • Side-by-side, duplex, triplex and fourplex properties 
  • Max beginning R-value cannot exceed R-11 
  • Must insulate to R-38 
  • Residences must be primarily heated by PGE, Pacific Power, NW Natural, Cascade Natural Gas or Avista
