Portland Neighborhoods We Serve
We serve homeowners across Portland including North Portland neighborhoods like Kenton, St. Johns, Arbor Lodge, Humboldt, and Boise, Northeast Portland neighborhoods including King, Sabin, and Beaumont-Wilshire, and Southeast Portland neighborhoods such as Woodstock, Reed, Sellwood-Moreland, and Mount Tabor.
Many Portland homes in these neighborhoods are craftsman bungalows, Tudor revivals, and mid-century ranches built between 1920 and 1970. These homes are excellent candidates for ADU additions, full gut remodels, and secondary structure builds. We assess each property individually given the age-related conditions common in Portland's housing stock.
Portland BDS Permitting Process
All residential construction within Portland city limits is permitted through the Portland Bureau of Development Services. Portland BDS has specific ADU regulations that were significantly updated in 2018 and 2020, making detached ADUs easier to permit than they were previously. Portland now allows ADUs on all single-family and some multi-family lots without owner-occupancy requirements.
Portland BDS permit review for ADUs and additions typically runs longer than Clark County, often 8 to 16 weeks or more for complex projects. We submit complete applications with all required drawings to minimize review comments and get to construction as quickly as the process allows.
