Shed permit rules in Pittsburg, CA — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
Sheds and accessory structures under 120 square feet generally do not require a building permit in Pittsburg under California Building Code Section 105.2. Larger sheds and any structure with electrical, plumbing, or mechanical must be permitted and meet zoning setbacks (typically 3-5 feet from side/rear property lines).
Shed and small accessory-structure regulation in Pittsburg follows the California Building Code (CBC) Section 105.2 and California Residential Code (CRC) Section R105.2, as adopted into the Pittsburg Municipal Code, plus local zoning setback rules. Per state code, one-story detached accessory structures used as tool and storage sheds, playhouses, and similar uses that do not exceed 120 square feet in floor area are exempt from building permits. The exemption does not waive zoning compliance, so the structure must still meet Pittsburg's accessory-structure setbacks (commonly 3 feet from side and rear property lines for small sheds in single-family zones) and height limits (usually 10-15 feet for non-permitted sheds). Any shed that includes electrical wiring, plumbing, or gas piping still requires the applicable trade permits. Sheds larger than 120 sq ft require a building permit with foundation review, wall bracing, and potentially structural engineering. Accessory structures cannot be used as habitable space; to be lived in, they must meet ADU standards under CA Gov Code 65852.2. In fire hazard areas, accessory structures may need to comply with Chapter 7A ignition-resistant construction. HOAs may impose color, siting, and material rules beyond the municipal code.
