Privacy fences in Bexar County are generally allowed up to 8 feet in rear yards and 4 feet in front yards. San Antonio requires the finished side facing outward. Permits are required for masonry walls and fences over 8 feet.
San Antonio Unified Development Code regulates fence heights: up to 8 feet in rear and side yards, 4 feet in front yards (3 feet if solid in certain zones). Front-yard fences must allow at least 50% visibility in most residential zones. The finished or attractive side must face outward toward neighbors and streets. Masonry walls and fences over 8 feet require building permits and possibly engineering. All fences must comply with sight-triangle requirements at intersections. In unincorporated Bexar County, the county building code applies with similar standards. Prohibited materials in residential areas include razor wire and electrified fencing. Swimming pool fences must comply with specific barrier requirements under the International Building Code.
Non-compliant fences may be cited through code enforcement with fines up to $2,000 per day. Unpermitted masonry walls may require retroactive permits.
