SDCI Closures, Service Updates, and Inspection Requirements

SDCI customer service areas remain closed until further notice and continue offering services online. King County has approval from the State Department of Health to allow all private construction activities that are low-risk and adhere to strict COVID 19 Job site Requirements. The City of Seattle has issued requirements for construction projects seeking inspections. The City WILL NOT INSPECT any site that does not follow these requirements.


Summary: Seattle has three zones in which single family homes are the predominant type of development: SF 9600, SF 7200 and SF 5000. The abbreviation “SF” stands for Single Family, and the numbers following the abbreviation indicate the minimum lot area generally needed to build a home in that zone.1 Other than the differing lot size requirements, Land Use Code standards that regulate the size and location of buildings are the same for all single family zones. Development in Residential Small Lot (RSL) zones is subject to different standards and is beyond the scope of this Tip.
