Density Bonus Law
Portland's Residential Infill Project (RIP), effective August 2021, fundamentally restructured single-dwelling zones (PCC 33.110) to allow duplexes, triplexes, and fourplexes by right in most residential lots, with a density bonus to six units when at least half are affordable. The Inclusionary Housing program (PCC 33.245), in effect since February 2017, provides Floor Area Ratio (FAR) and height bonuses for buildings of 20+ units that include affordable units.

Portland uses PCC 33.130 (Commercial/Mixed Use zones) and PCC 33.140 plan-district overlays to direct higher-density mixed-use development along MAX Light Rail and frequent-bus corridors. PCC 33.130.040 establishes the Center & Corridor concept, and station-area plan districts (Gateway, Lents, North Macadam, Central City) apply tailored FAR bonuses, reduced parking minimums, and affordable-housing requirements. Oregon's Climate Friendly and Equitable Communities rules (OAR 660-012) reinforce these standards statewide.
