Building Construction Information
Douglas County, like all local jurisdictions, requires permits for construction and land use activities. In addition,
Transportation and Land Services has been structured to provide a "one stop" approach to obtaining all your local construction and land use permits.
Certain permits are required prior to beginning construction, alteration, and/or demolition of all structures in Douglas County. The State of Washington requires all cities and counties to enforce an assortment of construction-related codes, all of which are intended to establish a minimum standard of safety, health, efficiency and accessibility throughout the state.
Check with us before beginning any project to determine what, if any, permits you might need.
