Shed Installation · San Francisco County, California
In San Francisco County, a Shed Installation under 120 sq ft generally does not require a building permit. At or above 120 sq ft, a permit is required.
The City and County of San Francisco exempts one-story detached tool and storage sheds from building permits provided the floor area does not exceed 120 square feet. Furthermore, the shed must not be more than 10 feet high. The exemption is strictly limited to non-habitable storage, and only one permit-exempt storage shed is allowed per lot or yard without obtaining a building permit. Building permits in San Francisco County are handled under the San Francisco Department of Building Inspection building code. Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with City and County of San Francisco Permit Center.
