In unincorporated San Diego County, one-story detached sheds under 120 square feet are exempt from building permits if they maintain at least 6 feet clearance from other buildings. Larger sheds require permits. All sheds must comply with zoning setbacks and lot coverage.
Under San Diego County's adopted building code (California Building Code with local amendments), one-story detached accessory buildings used as tool and storage sheds are exempt from building permits if: the floor area does not exceed 120 square feet, the structure maintains at least 6 feet clearance from other buildings on the lot, and no electrical, plumbing, or mechanical work is involved (those require separate permits). Sheds over 120 square feet require a building permit with plan review and inspections. All sheds must comply with County Zoning Ordinance setback requirements, which vary by zone (typically 5-10 feet from property lines). Lot coverage limits apply. In fire-prone areas (much of unincorporated San Diego County), sheds may need to meet fire-resistive construction requirements. Prefabricated sheds over 120 sq ft must bear a state HCD insignia.
Sheds over 120 sq ft without permits may result in stop-work orders, required after-the-fact permits with additional fees, or demolition orders if they cannot meet code.
