Fence Regulations in San Antonio, TX

If you live in San Antonio or are thinking about moving there, fence regulations are one of those things you probably won't think about until they affect you directly. San Antonio has 4 specific rules on the books covering different aspects of fence regulations, and some of them might surprise you.

Retaining Walls

San Antonio requires a new or repaired retaining wall to be designed by a registered professional engineer, with plans approved by the director of public works before a building permit issues. Walls must resist the maximum lateral pressure of retained material, and unsafe walls can be declared a public nuisance.

Key details: Governing article: SAMC Ch. 6, Art. IX, Secs. 6-181 to 6-196. Design requirement: Registered professional engineer plans. Approval needed before permit: Director of public works sign-off. Dangerous wall repair cost: Borne entirely by the owner. Penalty: Misdemeanor, separate offense per day.

Sec. 6-196 makes it unlawful to erect, construct, enlarge, alter, repair, move, improve, remove or demolish a retaining wall contrary to Article IX. A violation is a misdemeanor, punishable under Sec. 1-5, with each day a violation continues, is committed or is permitted treated as a separate offense.

Height Limits

San Antonio UDC §35-514 limits solid front-yard fences to 3 feet and open/decorative fences to 4–5 feet in front yards. Rear and side yards allow up to 8 feet under certain conditions. Historic districts require HDRC approval. Permits are required for all fences except exempt repairs.

Key details: Front Yard (Solid): 3 ft max. Front Yard (Open): 4 ft max. Max Height: Up to 8 ft (conditions). Permit: Required (6-month validity).

Fence without permit: citation. Non-compliant height: removal or modification required. Fine $100–$2,000.

Fence Permit Requirements

San Antonio requires a building permit before constructing or substantially replacing a residential fence, issued by the Development Services Department for a flat $25 fee. The only exemption is for minor repairs: work on fences six feet or shorter that replaces less than 25 percent of the fence's total contiguous length does not need a permit.

Key details: Residential fence permit fee: $25.00 flat rate. Exempt height: Fences six feet or shorter. Exempt repair scope: Under 25% of fence length replaced. Issuing agency: Development Services Department. Governing sections: SAMC Sec. 10-6(e), Sec. 10-38.

Fence work that exceeds the Sec. 10-6(e) exemption, replacing 25 percent or more of a fence's run, building over six feet, or new construction, requires a DSD permit before work begins. Building or replacing a fence without the required permit leaves the work unpermitted and subject to a stop-work order; the owner must apply for the permit and pass inspection to bring the fence into compliance.

Material Restrictions

San Antonio UDC §35-514 specifies approved fence materials: wood, chain link, stone, rock, concrete block, masonry brick, decorative wrought iron, or similar durable materials. Prohibited materials include plywood under 5/8", particle board, paper, plastic tarp, and items not designed as fencing.

Key details: Approved: Wood, chain link, stone, iron. Prohibited: Particle board, tarp, thin plywood. Barbed Wire: Prohibited residential. Setback: None: can be on property line.

Non-compliant materials: citation, modification required. Fine $100–$2,000. Barbed wire in residential: removal required.

The rules around material restrictions in San Antonio lean permissive, but that does not mean anything goes.
