Inclusionary Housing

The City of Portland has identified the need for a minimum of 23,000 additional housing units to serve low and moderate-income households. The Inclusionary Housing program is designed to help meet this need, working to preserve economically diverse neighborhoods and housing affordability.

About the Program

Inclusionary Housing requires that all residential buildings proposing 20 or more new units provide a percentage of the new units at rents affordable to households at 80% of the median family income or below.

The City has defined additional regulatory options under the umbrella of this requirement. Permit applications must include one of the options to provide affordable housing in their proposal, or applicants can opt to pay a fee-in-lieu at permit issuance.

All permit applications subject to or electing into Inclusionary Housing are reviewed by the Portland Housing Bureau. PHB staff are available to assist with questions.
