Step 1: Does Your Project Need a Permit?
The most important thing to remember when navigating the permitting process, is to start early and ask often! Of course, one of the first questions is whether you need a permit at all.
Which Projects Require Permits?
A permit is required for most new residential and commercial construction in Thurston County. Please click here for guidance.
If you are purchasing land, ask the seller if the county has already issued permits for sewage disposal, drinking water supply, site access etc.
If you have the tax parcel number for the property, a Permit Assistance Center Employee can check the status of prior approvals for you. Commonly requested (but not all) information is also available online through our "Search Permit Archives" database.
If you do not know the tax parcel number, call the Thurston County Assessor's Office at (360) 786-5410 or look up the number on the Assessor's Parcel Search website. Important: When using parcel search, use the street address and the street name only. Do not use directions or words such as "Way" or "Avenue" or "Blvd." For example, for Thurston County Building 4, you'd type in 929 and then Lakeridge -- not 929 Lakeridge Drive S.W.
