Building and land use permits in unincorporated King County

DDES issues new permits for property in unincorporated King County only. Check jurisdiction and zoning first to determine whether property is in unincorporated King County or within city limits.

For property within a city boundary (Seattle, Bellevue, Renton, etc.) in King County, contact the city directly for its permitting regulations, not DDES. See links to cities and towns at www.choosewashington.com/counties/Cities.asp?county_id=53 (external link).
