Full Breakdown
Thurston County Code Chapter 21.69 lets residents run a home occupation in any residential zone as a matter of right if there are no exterior structural changes, no outdoor sales or storage, no employees besides household residents, and no sign. Add one outside employee, indoor storage, or signage meeting Section 21.75.180, and the business needs administrative site plan review under Chapter 21.84, capped at 500 square feet of building area. Anything beyond that, more employees, exterior alterations, customer traffic, requires a special use permit under Chapter 21.87, which still caps building area at 500 square feet and bans drive-through service.
Violations & Fines
Operating past the by-right limits without site plan review or a special use permit is a zoning code violation Thurston County Community Planning can cite and order corrected.
