Despite supply chain disruptions, a protracted concrete strike, labor shortages and high construction costs, a record 495 DADU’s were built in Seattle last year. This DADU located in the Green Lake neighborhood sold as a condo in September for $945,000. It is representative of the increasing number of DADUs being build by larger homebuilders for sale. A trend that is likely to continue even as rising interest rates and cooling housing prices slow construction of larger new homes and multi-family projects.
