Tuolumne County limits building coverage by zoning district. Agricultural zones limit coverage to 25% of parcel or 4,000 sq ft, whichever is less. Residential zones have their own coverage standards under Title 17.
Tuolumne County's zoning ordinance (Title 17) regulates lot coverage β the percentage of a parcel covered by buildings and impervious surfaces. Agricultural zones (A-10, A-20) limit building coverage to 25% of the parcel or 4,000 square feet, whichever is less, for accessory structures including garages. Residential zones have their own coverage standards that vary by district. The county's Sierra foothill terrain and large lot sizes in rural areas mean most properties have coverage well below maximums. Impervious surface coverage affects stormwater runoff and may be additionally regulated through grading permits and development review. Lot coverage calculations include all roofed structures.
Exceeding lot coverage: building permit denial or code compliance enforcement. Variance available through Planning Commission.
