Residential Infill Project: Right-sizing new homes and increasing housing options that blend into single-family neighborhoods

The Residential Infill Project (RIP) is exploring ways to allow more housing units in single-family neighborhoods.

By applying better controls on house size and improving the way houses relate to each other, accessory dwelling units (ADUs), duplexes and triplexes can be carefully introduced into residential neighborhoods, while keeping the size and scale of new buildings relatively small.

Portland’s single-family neighborhoods used to allow a lot more middle housing, such as courtyard apartments, duplexes and stacked flats.

These housing types provide options to detached single-family homes at a lower price point. We’re trying to bridge the gap between past zoning and the present to create more housing stock and choices for Portland’s growing population. — Morgan Tracy, RIP Project Manager

But where will these new regulations/rules apply? A housing overlay zone is also being considered as part of RIP to answer that question.

Currently, staff are following City Council direction to include neighborhoods that are approximately five blocks (a 5-minute walk) from designated centers, corridors with frequent bus service, and MAX stations.

Also included are neighborhoods that may be slightly farther from centers and corridors but are still close to downtown, have good transit access, include a well-connected street grid and are near schools, parks and jobs.
