Shed permit rules in Riverside, CA — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
One-story detached storage sheds 120 sq ft or smaller are exempt from a building permit under California Residential Code R105.2 and Riverside Municipal Code Title 16, but they must still meet zoning setbacks in RMC Chapter 19.440 (Accessory Buildings and Structures).
Sheds, playhouses, and similar one-story detached accessory structures up to 120 square feet are exempt from a building permit per California Residential Code Section R105.2, which Riverside has adopted through RMC Title 16. Anything larger than 120 sq ft, or any shed with electrical, plumbing, or mechanical service, requires a full building permit issued by the City of Riverside Building & Safety Division (3900 Main Street, 3rd Floor). Even when no building permit is needed, RMC Chapter 19.440 (Accessory Buildings and Structures) still applies: the shed must respect the side and rear yard setbacks of the underlying residential zone, cannot be placed in the required front yard, and cannot block utility or drainage easements. Riverside lies inside CAL FIRE-mapped Very High Fire Hazard Severity Zones in parts of the city; sheds in those areas must use ignition-resistant materials per Chapter 7A of the California Residential Code.
Building a shed without a required permit, or in violation of zoning setbacks, is a municipal code violation enforced by Code Enforcement under RMC Title 1 (administrative citations). Riverside's administrative citation fines under RMC §1.17 are typically $100 for the first violation, $200 for the second within a year, and $500 for each subsequent violation, plus the cost of bringing the structure into compliance or removing it.
