Backyard cottages sprouting in Seattle
“…in late 2009, the Seattle City Council adopted legislation allowing smaller second homes, so-called “backyard cottages,” to be built citywide…
Seeking to promote both affordable housing and a gentle, scarcely visible increase in density in single-family neighborhoods, the City Council in 2006 decided to allow what are officially called “detached accessory dwelling units” in a limited part of the city.
This pilot program in Southeast Seattle allowed backyard cottages only east of Interstate 5 and south of Interstate 90. The program proved satisfactory to the City Council and it made construction of backyard cottages legal throughout the city in December 2009.”
