Permit Requirements: Anza vs Corona

Riverside County requires a building permit for fences over 6 feet and for retaining walls over 3 feet above lower grade, per California Building Code and Ordinance 457. Fences on property lines between neighbors generally do not need a permit at 6 feet or under, but permits are still needed if engineered footings, masonry, or pool-barrier compliance is involved.

Corona requires building permits for fences over 6 feet tall, all retaining walls over 4 feet (measured from bottom of footing), pool enclosures, and walls supporting surcharge loads. Standard residential fences 6 feet or shorter typically do not require a permit but must comply with zoning height and setback rules.
