ADU Demand in Clackamas County
Clackamas County and its incorporated cities have seen increasing ADU construction activity since Oregon passed statewide ADU legislation that removed many local barriers. Lake Oswego, Milwaukie, and Happy Valley are among the most active ADU markets in the county. Willamette Falls-adjacent neighborhoods in Oregon City and West Linn have strong demand for additions and remodels given the age and character of the housing stock.
Canby, Gladstone, and rural Estacada properties offer large lots where detached ADUs, oversized garages, and shop buildings are feasible without the tight setback constraints that urban lots face.
Permitting in Clackamas County
Unincorporated Clackamas County properties use the Clackamas County Department of Transportation and Development for building permits. Incorporated cities each have their own building departments: Lake Oswego, Milwaukie, Oregon City, West Linn, Happy Valley, Canby, and Gladstone all issue their own permits. We identify the correct authority for your parcel and handle all permit documentation.
