Victorville, CA Accessory Structures: Shed Rules (2026)

California Residential Code Section R105.2 and California Building Code Section 105.2 list common exemptions from building permits including one-story detached accessory buildings used as tool and storage sheds, playhouses, and similar uses, provided the floor area does not exceed 120 square feet. Victorville adopts these codes through Victorville Municipal Code Title 15. Even permit-exempt sheds must comply with zoning in Title 17 Development Code: typical minimum setbacks of three to five feet from rear and side property lines, maximum height around 10 to 12 feet, and a rear-yard coverage cap (commonly 30 percent). High Desert wind loading is significant: Victor Valley typical Risk Category II design wind speeds hit the 110 mph range, so even small sheds benefit from anchoring to a slab or ground anchors to avoid becoming wind-borne during Santa Ana events. Sheds with plumbing, gas, or electrical service require separate trade permits regardless of size. Sheds over 120 square feet or with habitable features require a full building permit. Placement cannot damage Joshua trees — CDFW authorization is required if a shed pad will disturb one.
