Auburn sits on the line between King and Pierce County, and that decides which office reviews your permit. Build Sherpas draws the plans and runs the permit, whether it goes to the City of Auburn, King County, or Pierce County.

Auburn address, which county reviews it
Lakeland Hills is inside the City of Auburn, so the City of Auburn handles the permit. Lea Hill is mixed, so we check your parcel first and tell you which office you are dealing with. Codes, forms, and fees differ between them.
What Build Sherpas does here
We don't build, and we don't engineer or stamp. Where engineering is required, our sister firm Dow Engineering PLLC, in the same office, handles it. Air leakage tests come from WA Blower Door.
