What is Portland's Residential Infill Project (RIP), and what does it allow?
Answered by AskBaily Editorial · Updated
Short answer
The Residential Infill Project, adopted 2020, reformed Portland's single-family zoning to allow up to four units (duplex, triplex, fourplex) on most R5 / R7 / R10 lots, plus cottage cluster developments of up to six units. RIP preempted most prior single-family-only restrictions, capped parking minimums, and scaled housing density. It is the single biggest zoning reform Portland has shipped in a generation.
