In unincorporated Orange County, one-story detached sheds under 120 square feet are exempt from building permits. Larger sheds require permits. All sheds must comply with zoning setbacks, lot coverage, and fire-zone requirements.
Under the California Building Code as adopted by Orange County, one-story detached accessory buildings used as tool and storage sheds are exempt from building permits if: floor area does not exceed 120 square feet, height does not exceed 12 feet, and no utility connections are involved (electrical, plumbing, and mechanical require separate permits). Sheds over 120 square feet require a building permit with plan review. All sheds must comply with zoning setbacks (typically 5 feet from property lines, varying by zone), lot coverage limits, and height restrictions for accessory structures. In fire hazard areas, fire-resistive construction may be required. Prefabricated sheds over 120 sq ft must bear a state HCD insignia. The county's online permit system (ePermit) handles many standard applications.
Unpermitted sheds over 120 sq ft face stop-work orders, required permits with double fees, or demolition if they cannot meet code.
