Land use inspection

Land use inspections

Department of Permitting land use inspectors monitor construction of roads, parking lots, road frontage (such as curbs, gutters, sidewalks), drainage facilities, erosion control, and other site work on developments or building permits to ensure County regulations and permit requirements are met. Inspections are limited to projects located in unincorporated King County and some cities with an Interlocal agreement with the Department of Permitting.

Land use inspections are typically related to subdivisions (plats), short subdivisions (short plats), commercial developments, right-of-way permits, and some grading and residential permits with site improvements.

Land use inspections staff provide site inspections, approvals, complaint response, bond release, bond forfeiture, and engineering review of design plan changes, as well as issue an extension to right-of-way use permits (limited).

Schedule a land use inspection by calling 206-296-6600, or go to land use inspections for detailed information on how and when to call and schedule land use inspections.
