Shed permit rules in Corona, CA — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
Corona allows sheds up to 120 sq ft without a building permit under CRC R105.2, but zoning setbacks (3-5 ft) still apply. Sheds over 120 sq ft need full building permits.
Under the California Residential Code §R105.2 (adopted by Corona via CMC Title 15), one-story detached accessory structures used as tool sheds, playhouses, and similar uses do not require a building permit if they do not exceed 120 square feet in floor area. However, electrical, plumbing, and gas work to a shed always requires permits regardless of size. Even permit-exempt sheds must comply with Corona zoning standards in CMC Title 17: typical placement standards are 3-5 feet from rear and side property lines (5 feet if the shed has a wall over 6 ft tall), located behind the front building setback line, and not in required side-yard access easements. Maximum height for accessory structures in residential zones is typically 12 feet (one story). Cumulative coverage of accessory structures cannot exceed a percentage of the rear yard (often 30-50%). Sheds over 120 sq ft require a building permit, plan check, foundation, and may trigger additional fire-rating requirements if within 3 feet of the property line. Pre-fab metal sheds, plastic resin sheds (Rubbermaid, Lifetime), and wood sheds (Tuff Shed) are all permitted if they meet size and setback rules. HOAs commonly impose additional restrictions on shed materials, color, and visibility from the street.
