It is required by the city of Portland when selling your house after January 1, 2018. If you are selling with an agent, on your own, or simply advertising your home for sale, then you must obtain a Home Energy Score Report.
The Home Energy Score Report may only be performed by a state licensed Home Energy Assessor and is good for 2 years.
A Home Energy Score Report will become void and invalid if any alteration or remodel is done that affects the heated square footage of your home. A new Home Energy Score Report must then be obtained.
