Santa Ana Permit Requirements Rules (2026): What You Need to Know
Some RestrictionsThe Short Version
In Santa Ana, most wood, chain link, and wrought iron fences up to 6 feet in height do not require a building permit under the California Building Code as locally adopted, but all fences must comply with the city's zoning height limits and setback requirements. Masonry, concrete block, and brick walls over 4 feet in height require a building permit with engineered structural drawings. Any fence or wall exceeding 6 feet in height requires both a building permit and may require a zoning variance. Front yard fences require Planning Division review to confirm compliance with the 42-inch height limit.
Full Breakdown
Santa Ana's fence permit requirements are governed by the California Building Code as locally adopted in Municipal Code Chapter 8 (Building Code) and the zoning regulations in Chapter 41 (Zoning). Under the building code, fences constructed of wood, chain link, or wrought iron that do not exceed 6 feet in height are generally exempt from the building permit requirement. However, these fences must still comply with all applicable zoning height limits, setback requirements, and material restrictions — the building permit exemption does not waive zoning compliance. Fences in front yards must meet the 42-inch height limit and may require Planning Division review before installation.
For masonry, concrete block, brick, and stucco walls, a building permit is required for any wall exceeding 4 feet in height. The permit application must include structural engineering calculations and drawings prepared by a California-licensed structural engineer, as these wall types are subject to seismic loading requirements particularly important in Southern California. The building permit review process for masonry walls typically takes two to four weeks and includes plan check fees based on the project valuation.
Any fence or wall exceeding 6 feet in height — regardless of material — requires a building permit from the Building Division. Additionally, if the proposed height exceeds the zoning code maximum for the applicable yard area (42 inches for front yards, 6 feet for side and rear yards), a zoning variance must be obtained from the Planning Division before the building permit can be issued. Variance applications require a public hearing and are evaluated based on the specific circumstances of the property.
When a fence is built on top of a retaining wall, the combined height determines the applicable permit threshold. Residents should contact the Santa Ana Building Division at (714) 667-2700 or the Planning Division at (714) 667-2750 before beginning any fence or wall project to confirm permit requirements for their specific situation.
What Happens If You Violate This?
Installing a fence without a required building permit is a code violation. After-the-fact permit applications carry additional fees and penalties. Fences that exceed zoning height limits without a variance are subject to code enforcement action requiring modification or removal. Non-compliant masonry walls without structural engineering may be ordered removed as a safety hazard. Contact Code Enforcement at (714) 667-2780.
