Pet Groomer Rules

Thurston County classifies pet grooming as a 'personal service' under its Olympia Urban Growth Area zoning code, the same use category as barbershops and beauty shops. TCC 23.06.040's Table 6.01 permits personal services outright in every commercial district, and TCC 23.05.040's Table 5.01 does the same across all four village and shopping-center districts.
