Portland building & ADU permits
Recent permit activity, updated continuously.
Portland is Oregon's largest city and a national zoning-reform pioneer: Oregon's HB 2001 ended single-family-only zoning statewide, and ADUs are allowed by right within urban growth boundaries. Portland's permit layer carries no ZIP field, so Igni reverse-geocodes each permit's location to a ZIP using the free US Census geocoder before classifying it.

ADU types in the recent set
Housing law — Oregon
Oregon allows accessory dwelling units by-right in single-family zones within urban growth boundaries, with no owner-occupancy requirement and no extra off-street parking mandate.
HB 2001 (2019) legalized middle housing statewide — duplexes in mid-size cities and up to fourplexes, cottage clusters and townhouses in large cities and the Portland metro.
Portland ADU rules
Portland allows accessory dwelling units in its single-dwelling zones by right, meaning a proposal that meets the objective standards in Title 33, Chapter 33.205 of the City Code is approved through the building permit without a discretionary hearing. A lot with a house can generally have one ADU, or two where the lot has city-street frontage and meets the minimum lot size; ADUs may be interior conversions, attached additions, garage conversions, or new detached structures.
Oregon state law (ORS 197A.425) bars cities from imposing owner-occupancy or extra off-street-parking requirements on ADUs, so Portland requires neither. An ADU is generally limited to 75 percent of the main building's living area or 800 square feet, whichever is smaller, with basement conversions exempt from that size cap; detached units are typically held to about 20 feet in height (lower when placed inside required setbacks).
Portland's modern ADU rules grew out of its Residential Infill Project, which took effect in 2021 and also allows up to four units (or more with affordable housing) on many residential lots. The city's long-standing system-development-charge waiver for ADUs remains in effect, lowering one of the larger soft costs of building one.
