The county charges fees for the work associated with reviewing plans & drawings, and inspecting properties, construction sites and building work to make sure development meets regulations. We also collect impact fees for projects that increase the need for community services like fire services, parks, schools, transportation and environmental protection.

Elected Officials Authorize these Fees
Permitting fees are reviewed and adopted by the Thurston County Board of Commissioners. Thurston County government is authorized by the Washington State legislature to issue permits in unincorporated areas of Thurston County and collect fees. Permitted projects must meet state and federal laws for community growth, health and safety.  Some county departments and divisions are funded by the county's general fund which is a tax-sourced fund. Permitting is self-supporting through fees and does not rely on Thurston County's general fund.
