In unincorporated Bexar County there are no general height or style limits, but San Antonio caps residential fences at 6 feet in rear and side yards and 4 feet in front yards, with stricter corner-visibility rules.
Fence standards across Bexar County depend on which jurisdiction your address sits in. Unincorporated Bexar County has no zoning or height ordinance for fences, so height is typically governed by recorded plat notes, HOA covenants, or Texas common law of nuisance if a fence is built in bad faith solely to annoy a neighbor, the classic spite fence doctrine. San Antonio's Unified Development Code limits residential fences to 6 feet in rear and interior side yards, 4 feet in front yards, and requires a 25-foot visibility triangle at intersection corners where fences cannot exceed 3 feet. Fences over 7 feet are classified as structures and need a building permit. Commercial and agricultural properties follow separate rules. Fair Oaks Ranch, Hill Country Village, and Grey Forest include scenic or hillside restrictions, and many Stone Oak area HOAs require wrought iron or masonry rather than wood. Barbed wire is generally prohibited on residential lots inside cities.
