How permitting works in Washington
Washington counties are the mandatory permitting authorities for all unincorporated land. Their role is to provide a local office for residents to submit plans and receive inspections, ensuring that the state-mandated building code is applied uniformly across the county's rural and suburban areas.
Mandatory state code; local City/County enforcement.
