The new accessory dwelling unit regulations go into effect on August 8, 2019. This was a multiyear effort to help increase the number and variety of housing options in single-family zones and to remove barriers to developing accessory dwelling units in the city.
Recent legislation (Council Bill 119544) made it easier for property owners to build accessory dwelling units (i.e., backyard cottages) to give more housing options for people living in Seattle. In our digital age, having more people living on one parcel will likely also mean increased internet usage – and an increased need for broadband capacity. A home may already have an internet service connection, but that doesn’t necessarily mean that connection can easily be extended or shared with a new residence on the parcel.

The City of Seattle wants to remind homeowners of the grace period through June 30 for legalizing existing unauthorized backyard cottages. Under new regulations that went into effect December 4, 2009, backyard cottages became legal throughout Seattle. Previously, backyard cottages, also known as detached accessory dwelling units or DADUs, had been allowed only in southeast Seattle neighborhoods since 2006. Included in the December legislation is a grace period that allows owners of existing, unauthorized backyard cottages the opportunity to legalize their unit without penalty. Owners have until June 30, 2010 to apply for a building permit and until December 31, 2010 to obtain final inspection of the unit.
