Seattle Mayor Jenny Durkan signed the code changes approved by city council last week that are intended to increase the number of backyard cottages being built in Seattle. The Mayor also signed an executive order to address other issues that restrain construction including reducing construction cost, permitting time and complexity and exploring financing options for ADUs. The code changes will go into effect on August 8th. Limits to new house size (FAR restrictions) will go into effect six months from now.
