Research notes

Fourplex tier applies to cities with population ≥25,000, and to all cities inside the Portland Metro service district regardless of population. Triplexes, fourplexes, townhomes, and cottage clusters permitted by-right in all SF zones. Implementation deadline was June 30, 2022. Cities cannot impose design standards that effectively prohibit middle housing. DLCD provides model code under OAR 660-046.
