Before You Build in Victorville, CA: Permit & Rule Checklist (2026)

Victorville exempts only short fences from a building permit: walls and fences up to three feet tall in rear or side yards, or eighteen inches in front yards, need no permit under the locally amended California Building and Residential Codes. Anything taller triggers the standard building permit process through the Building Department.

Victorville only exempts short retaining walls from a permit: up to thirty inches measured from footing to top in rear or side yards, or eighteen inches from grade in front yards, unless the wall holds back a surcharge or impounds Class I, II or IIA liquids, which always needs a permit regardless of height.

Victorville caps fences and walls at eight feet citywide under Sec. 16-3.24.080, measured from the lowest ground level abutting the wall, unless a stepped design is used or the Planning Commission approves otherwise. Table 8-2 layers tighter district rules on top of that ceiling: most front yards allow no fence, while rear and side yards are capped at seven feet, six feet in R-2 through R-4.

Victorville enforces the California Swimming Pool Safety Act (H and S Code 115920-115929). Pools need at least two approved drowning-prevention features, typically a 60-inch enclosure and self-latching gate.

Victorville requires a building permit for any in-ground pool, spa, or above-ground pool deeper than 18 inches. Plan check covers the Swimming Pool Safety Act, setbacks, electrical bonding, and fencing compliance.

Victorville's Development Code caps a new accessory dwelling unit at 850 square feet for a studio or one bedroom and 1,000 square feet for two or more bedrooms, per Table 8-1. Table 8-3 sets a uniform 4-foot side and rear setback in every residential zone and limits a detached ADU to 16 feet in height, 25 feet if attached to the primary home.

Victorville lets homeowners convert an attached garage into an accessory dwelling unit without meeting standard residential setbacks. Development Code Section 16-3.07.030(a)(4)(ii) waives all side- and rear-yard setbacks for a garage or living area inside the primary dwelling that becomes an ADU, while any new construction outside that existing footprint is capped at a four-foot setback.

Victorville's Development Code caps an unpermitted backyard shed at 7 feet in height with no setback if it stays behind the roofline, but any structure needing a building permit, or taller than 7 feet, must sit at least 5 feet off the property line. Table 8-2 limits total accessory structure size to 400 square feet or 40% of the main house's floor area, whichever is greater.

Victorville Water District limits sprinkler irrigation to fixed clock windows year-round under Conservation Stage 1.

From October 1 through May 31, watering is allowed only between 9:00 a.m. and 3:00 p.m. Handheld hoses with shut-off nozzles and low-volume drip systems are exempt from the clock restriction.
