Portland’s housing stock spans over a century, from Craftsman bungalows in inner SE and NE to mid-century ranches in outer neighborhoods. The city sits in the Cascadia subduction zone, and unreinforced masonry buildings remain a significant earthquake risk. Industrial legacy along the Willamette’s east bank means DEQ cleanup sites are common. Oregon’s Measure 50 creates a gap between assessed and real market value that can affect tax planning. Permit history is dense in neighborhoods undergoing ADU and infill development.
