On October 6, 2008, the Seattle City Council adopted Council Bill 116275. This bill amends land use and zoning standards for Single Family zones to address the bulk, design, and environmental impacts of new structures on existing homes and the character of single family neighborhoods. Proposed amendments would address: the size of homes, garage size and location, eligibility of historic lots for development, and house design.

The amendments are anticipated to go into effect in mid-November.
