FENCE RULES – SAN ANTONIO (CITY), TEXAS

OVERVIEW

This page covers residential fences inside the City of San Antonio, Texas, including homes with agricultural acreage. The applicable zoning, actual property boundaries and any historic, corridor or neighborhood conservation district affect the project.

San Antonio requires a permit for new fences and most rebuilding. Its minor-repair exemption is limited to qualifying repairs of fences no higher than 6 feet. The ordinary front-yard limits are 3 feet for a solid fence and 5 feet for a combined or predominantly open fence; side and rear fences generally stop at 6 feet, with several specific 8-foot exceptions. Corner and driveway visibility can require a lower fence. Wood and chain-link are expressly recognized, while vinyl/PVC must satisfy the rule for similarly durable materials. Drainage easements, retaining walls, pools and special districts require separate attention.

Quick question	San Antonio answer
Permit or approval	New construction, expansion and work outside the limited minor-repair exemption require a fence permit. Repairs of a fence no higher than 6 feet qualify only up to 25% of its overall contiguous length.
Typical fence height	Front: 3 feet solid or 5 feet combined/predominantly open. Side/rear: 6 feet, with defined 8-foot branches. Qualified large lots can have a 6-foot predominantly open front fence.
Placement & property lines	Keep the fence on the lawful property and outside restricted sight areas or unauthorized public-property encroachments. Drainage easements and sport-court fences have additional placement rules.
Common fence materials	Wood: expressly recognized. Vinyl/PVC: not separately named; the similar-durability standard applies. Chain-link: expressly recognized, subject to yard, pool and special-district restrictions.
Important local conditions	Fence rules may be further affected by historic, corridor and neighborhood conservation districts, corner or driveway visibility, changes in grade, adjacent uses, pools, drainage easements and recorded restrictions.

The table above is for quick reference. The corresponding sections below explain the additional fence rules. Before purchasing materials or beginning construction, read the sections that apply to the property, review the linked official sources, and confirm site-specific questions with San Antonio Development Services Department or the responsible office identified for that issue. Updated November 2026.

GOVERNANCE

The San Antonio City Council adopts the Unified Development Code and building-related codes. The Development Services Department administers fence permits, zoning and code enforcement. Its Traffic review evaluates clear-vision areas. The Historic Preservation Officer and the applicable Development Services official determine compatibility in historic, corridor and neighborhood conservation districts. The Floodplain Administrator and Public Works handle the relevant floodplain, drainage and public-property issues.

San Antonio UDC §35-514 supplies the principal fence standards; City Code Chapters 6 and 10 add height procedures, maintenance and permit rules. San Antonio has adopted the 2024 International Residential Code and International Swimming Pool and Spa Code with local amendments. Applicable planned-development approvals, publicly imposed plat conditions and special-district rules remain part of the property’s requirements.

• Agricultural land and operations: Texas Agriculture Code §§251.005–251.006 protect qualifying agricultural operations and agricultural improvements, including fences serving the specified agricultural purposes. A city requirement applies to an agricultural operation inside city limits only if the statutory imminent-danger, less-restrictive-means and public-health findings are satisfied; city requirements do not apply to an agricultural operation outside city limits under §251.005. State and federal duties remain. Acreage alone does not make a residential privacy fence an agricultural improvement or establish an exemption. The linked statewide guide explains the conditions.

• Cultivation and livestock: Agricultural fencing standards depend on the land’s actual use, animal class and applicable local stock-law territory. Determine that scope before choosing a fence for cultivated land or livestock. These sufficient-fence standards are separate from ordinary yard-fence maximums; the statewide guide explains their height, gate and construction branches.

PERMIT AND APPROVAL REQUIREMENTS

• New fences and repairs: UDC §35-514 requires a building permit before fence construction, repair or expansion, except work expressly exempted by City Code §10-6(e). The fence exemption covers minor repairs to fences no higher than 6 feet; replacement of up to 25% of the overall contiguous length is minor repair. It does not exempt a new 6-foot fence. Work beyond that scope requires the permit.

• Application and inspection: The City’s fence information bulletin directs single-family, duplex and triplex projects to the Residential Fence Application in BuildSA, even when the lot has nonresidential zoning. Submit a basic site plan showing existing structures/buildings as a PDF. A recorded or proposed plat is not required for this application, but the owner remains responsible for the boundary. The published fee schedule lists a $25 residential fence permit fee; applicable additional processing or trade charges are separate. The City reviews the documents before issuance and payment. It does not require an inspection of the fence itself under this process; compliance remains enforceable.

• Electrical gates: An electrically controlled gate or electrical lighting system requires a separate electrical permit obtained by the licensed/registered electrical contractor and the applicable electrical inspections.

• Special districts and height relief: In a historic district, corridor overlay or neighborhood conservation district, the designated official must find compliance and compatibility before issuing the fence permit. Use the actual district standards. Higher-front-fence special exceptions and other variances follow the applicable UDC process. Chapter 6’s separate over-6-foot procedure and its express exceptions are described below.

• Retaining walls: City Code §10-6(e) exempts a retaining wall no higher than 4 feet measured from grade at the front of the wall to its top, unless it supports a surcharge or impounds the listed flammable liquids. This local measurement differs from footing-bottom measurements in some model codes. UDC §35-514 separately requires retaining walls along or within a public right-of-way to meet the building code and Chapter 6 Article IX; those over 3 feet require engineer-designed, signed and sealed plans. A required protective barrier atop a retaining wall is not treated as a fence under that provision.

• Drainage and floodplain work: A fence crossing a drainage easement must satisfy the applicable drainage design and access conditions. A fence within an easement in the 100-year floodplain requires a floodplain development permit. Other regulated floodplain development remains subject to Appendix F. Obtain the applicable review before placing posts, fill or a wall in a regulated drainage area.

• Private pool construction: New pool barriers follow the 2024 ISPSC and San Antonio amendments. The City reduces the temporary barrier minimum to 3 feet for an in-ground pool or spa construction site, from first excavation until the permanent barrier is complete. This is not the permanent-barrier minimum. Qualifying existing private pools built before January 1, 2010 also have the specific maintenance rule below.

FENCE PLACEMENT RULES

Use the deed, recorded plat, survey and easement instruments to establish the lawful fence line. The ordinary fence section does not state one universal numeric setback from every private boundary. Existing fences, curbs, parcel maps and mowing lines are not conclusive boundary evidence. Do not build over a neighbor’s property line.

• Public property and sight areas: City Code §6-1 prohibits placing a fence or other obstruction on City-owned or controlled real estate without the City Council’s ordinance consent. Keep streets, sidewalks and lawful access clear. Corner and driveway sight triangles use the curb-based geometry below, not an assumed property-line setback.

• Drainage-easement crossings: Where an applicable plat/drainage easement crosses a lot or property line, the City’s Storm Water Design Criteria Manual §15.5 prohibits fencing that interferes with adequate flow. A permitted crossing must place the fence bottom above the design flow line by the flow depth plus required freeboard, or use hinges or another design allowing the design flow to pass. Provide design details, a hinged gate across the easement’s entire width, continuous maintenance access for stormwater operations, and posts designed to resist flow and debris. The plat may independently prohibit fences, walls or other obstructions that impede drainage. Do not treat these conditions as permission to disregard the recorded easement.

• Floodways: Appendix F prohibits encroachments, including fill and other development, within the adopted regulatory floodway unless a registered professional engineer certifies no increase in flood levels during the regulatory discharge. Other applicable flood-hazard reduction requirements still apply.

• Home sport courts and enclosed courtyards: Sport-court fencing belongs only in a side or rear yard and must be at least 5 feet from the side or rear property line of an adjacent single-family use or residential zoning district and from a public or private street. Walls connected to a dwelling and enclosing a courtyard with interior access must meet all building setbacks and count as part of the home’s floor area.

• Surface-water drainage: Texas Water Code §11.086 prohibits diverting or impounding the natural flow of surface water, or allowing that diversion or impoundment to continue, in a manner that damages another person’s property by overflow. Fence panels, footings, walls and changed grades must be considered together with the property’s drainage routes and recorded rights.

• Existing shared or attached fences: Except by mutual consent or the statutory process, a person may not remove a separating or dividing fence in which that person is a joint owner, or a fence attached to one owned or controlled by someone else. Agriculture Code §§143.122–143.123 provide six-month written-notice procedures for withdrawing an interest in an attached fence and for an owner of a fence wholly on the owner’s land to require an attached fence’s disconnection. This is not a six-month notice rule for every removal, a presumption of joint ownership or a general equal-cost requirement.

• Underground utilities before digging: Request a Texas811 locate before digging posts, follow the ticket’s lawful start time, check operator responses against site markings, and resolve missing or conflicting information before excavation. Preserve the marks and dig carefully. Arrange separate identification of private lines the service may not mark. Texas excavation-notice law and separate pipeline rules have different depth, tool, exception and ticket requirements; owning the yard does not establish a blanket exemption.

• Pipeline corridors: For work on or affecting a pipeline easement or right-of-way, notify the pipeline operator and complete the applicable construction-safety arrangements before work. Required protective work may involve payment of reasonable, necessary and documented costs before construction. Existing written agreements and statutory exceptions can control. This is separate from an 811 locate; the statewide guide explains the applicable routes and limits.

FENCE HEIGHT AND VISIBILITY RULES

• Ordinary residential yards: The maximum front fence is 3 feet solid or 5 feet combined or predominantly open. Side and rear fences ordinarily may reach 6 feet. The maximum may not exceed the abutting property’s permitted maximum except under the specifically stated §35-514(c)(2) branches. A predominantly open fence has at least 70% open surface area. A combined fence has a solid lower portion 18–36 inches high and an upper portion with openings equal to 50% of that upper area; its solid portion cannot exceed 3 feet.

• Measurement and retaining walls: Measure vertically from the lowest adjacent ground level on either side to the tallest fence element, excluding decorative features affixed atop a column, pillar or post. Existing retaining walls count in fence height unless necessary for the structural soundness of building construction on the lot or abutting a drainage easement or drainage infrastructure.

• Larger front yards: A 6-foot predominantly open front fence is allowed by right on a residential lot of at least 20,000 square feet with at least 100 feet of street frontage, where the primary building meets the district’s minimum setback. Other residential lots need the specified special exception. These are cumulative conditions, not an acreage-only exemption.

• Eight-foot residential branches: Section 35-514(c)(2) allows fencing up to 8 feet where a principal dwelling on either side has a ground-floor elevation at least 4 feet above the shared lot line; along a side/rear lot line adjoining an alley, railroad right-of-way or a street other than a local street; where the City Council authorizes the extra height through rezoning or specific-use approval; or along a side/rear line of a single-family, duplex or mixed-residential use adjoining multifamily, commercial, industrial or park use. It also covers a side/rear fence on a single-family property with a qualifying rear-yard in-ground pool/hot tub or above-ground pool, or a side/rear fence on a single-family property adjoining one with such a pool or hot tub. A public/institutional sound or security fence is a separate branch, not an ordinary homeowner exemption.

• Sloping ground: On a side or rear slope, the fence top may be level and perpendicular to the support posts above 6 feet if the height at the highest elevation does not exceed 8 feet, as illustrated in §35-514. When that subsection allows a fence over 6 feet, all side and rear fences may be allowed up to 8 feet above grade to maintain a uniform appearance.

• Other property-specific heights: An approved PUD plan may designate side/rear fences up to 8 feet. Home sport-court fencing has a 12-foot maximum, subject to its placement limits. A dwelling-connected enclosed courtyard wall may reach one story. Section 35-514(c)(3) also permits a fence as tall as the adjacent building when entirely inside all required building setbacks, attached to the main structure, and serving its security or intended use. This is not a boundary-fence allowance.

• Vacant residential lots: A predominantly open fence up to 6 feet may enclose a vacant lot. After a house is constructed, subsection (b)(3) requires its front portion to be removed or reduced to 3 feet solid or 4 feet predominantly open, unless it qualifies for another higher-fence provision. This particular conversion rule uses 4 feet even though the ordinary residential table uses 5 feet for a predominantly open front fence; have Development Services apply the relevant branch to the conversion.

• Over-6-foot procedure: City Code §6-2 ordinarily requires Development Services to contact all abutting owners and receive no opposition, or requires City Council permission by ordinance, for a fence over 6 feet. It states a 12-foot ceiling, but expressly excludes fences specifically required or allowed to be higher by another code provision. Do not apply this process as an additional universal condition on the UDC’s expressly authorized taller fences or treat 12 feet as an ordinary entitlement.

• Corner and driveway visibility: On a residential corner lot, no fence over 3 feet may occupy the triangle measured 25 feet in each direction from the street curb. At a residential driveway, accessway or alley intersection with the street, use 15 feet in each direction from the intersection with the street curb. Development Services may approve a smaller area only through the stated intersection-sight-distance administrative exception; variances follow §35-482. These limits are separate from the ordinary yard maximum.

• Ordinary pool-barrier height and clearance: Under the adopted 2024 ISPSC §305, the pool or spa barrier is at least 48 inches high, measured outside the barrier, around its whole perimeter and for 3 feet horizontally outside it. The bottom gap is at most 2 inches over nonsolid grade such as grass or gravel or 4 inches over a solid surface. A barrier mounted atop a pool or spa structure has no more than a 4-inch gap above the structure. Openings cannot pass a 4-inch sphere. Qualifying cover and other alternatives are described below.

• Pool doors, gates and latches: Pedestrian access doors and gates in the barrier must open away from the pool, self-close, self-latch and accommodate a locking device. Doors and gates may not swing over stairs. Utility and service access stays locked when unused. Multiple gates need one secured leaf and a self-latching adjacent leaf. At residential pools, an outside-accessible latch release that is not self-locking must be at least 54 inches high; a self-locking key, electronic or combination control and release must be no higher than 54 inches. If the only release is on the pool side, it must be at least 3 inches below the gate top. For an inside release, openings within 18 inches of the latch cannot exceed ½ inch.

• Building-wall access and covers: Where a one- or two-family dwelling, townhouse or its accessory-structure wall forms part of the barrier, access doors, gates and operable windows with sills below 48 inches above the indoor floor need the specified UL 2017 alarm protection, a listed ASTM F1346 safety cover, or approved equivalent protection. In ordinary dwellings, alarm-deactivation controls are at least 54 inches above the floor; the specified accessible dwelling units use 48–54 inches. Separately, a spa or hot tub with an ASTM F1346 lockable safety cover, or a swimming pool with an ASTM F1346 powered safety cover, qualifies for §305.1’s exception from §§305.2–305.7.

• Pool-wall and natural-barrier alternatives: An onground pool wall can serve as the barrier only if it meets the code’s height and opening rules, rests on grade and is approved for that purpose by the manufacturer. A top-mounted barrier must follow manufacturer instructions and meet the combined height and opening standards. Access ladders or steps must be secured, locked or removed unless separately enclosed, and the resulting openings cannot pass a 4-inch sphere. The shoreline alternative requires no public shoreline access and barriers extending at least 18 inches beyond the water’s edge. Natural topography must prevent direct access and receive approval providing equivalent protection. A waterfront location alone does not waive the barrier.

• Private pools built before 2010: The City’s property-maintenance provision applies to existing private outdoor pools, hot tubs and spas built before January 1, 2010, containing water deeper than 24 inches. It requires a complete 48-inch barrier measured away from the pool and lockable or self-closing/self-latching gates and doors. A release below 54 inches above the gate bottom belongs on the pool side; a self-closing/self-latching gate must close and latch from an opening 6 inches from its post. Dwelling doors forming the enclosure must lock. Secure, lock, remove or separately enclose above-ground access ladders/steps. Do not reduce an existing enclosure’s effectiveness. The rule excepts the stated ASTM F1346 lockable spa/hot-tub covers and working powered swimming-pool covers. New construction is governed by the current adopted code, not this legacy provision alone.

MATERIAL AND CONSTRUCTION LIMITS

Wood and chain-link are expressly included in §35-514’s durable-material list, together with stone, rock, concrete block, precast concrete panels, masonry brick, brick and decorative wrought iron. Other materials must have similar durability. Vinyl/PVC is not separately named; its use must fit that standard and any district-specific restrictions.

• Prohibited materials: Do not use castoff, secondhand or other items not originally intended for fence construction or maintenance; plywood thinner than ⅝ inch or a grade not approved by Development Services; particleboard; paper; visqueen/plastic sheeting; plastic tarps or similar materials; or sheet, roll or corrugated metal. Barbed wire, razor wire and similar material capable of significant physical injury are prohibited for ordinary residential fencing. The government/private-nonresidential barbed-wire exceptions do not authorize a home privacy fence.

• Structural design: Freestanding non-load-bearing walls are fencing under the UDC. Walls and solid screen fences over 8 feet require a licensed engineer’s certification that their foundation and supports resist the building code’s wind loads. Retaining walls have their separate building-code and right-of-way requirements.

• Street-facing and required-fence maintenance: Under City Code §6-52, fences facing the street or adjacent to a public way, and fences required by other law, must remain structurally sound and in good repair. Correct lean greater than 15 degrees; rotted, fire-damaged or broken wooden posts/crossmembers; broken, fire-damaged or missing slats; and broken or severely bent metal posts or torn, cut or ripped metal fencing; and loose bricks, stones, rocks, mortar or similar masonry. A fence or portion may be removed if the remainder is safe and in good condition and no other law requires the fence.

• Subdivision perimeter fences: An established subdivision’s required perimeter fence may carry continuing plat and association-maintenance obligations. Do not change a shared or required perimeter fence as though it were solely an individual lot’s optional privacy fence. Developer design and common-facility requirements are not general construction specifications for every homeowner fence.

• Pool-fence construction: Solid barriers cannot have climbable handholds or footholds except normal construction tolerances and tooled masonry joints. Horizontal members with tops less than 45 inches apart belong on the pool side; vertical gaps and decorative cutouts are limited to 1¾ inches. With tops at least 45 inches apart, vertical gaps may be 4 inches but cutouts remain at 1¾ inches. Chain-link openings are at most 1¾ inches, including when secured slats reduce them. Diagonal openings also are at most 1¾ inches and diagonal members may not exceed 45 degrees from vertical. San Antonio’s chain-link prohibition for public pools is not a blanket prohibition for a private home pool.

• Mesh and screen pool barriers: Mesh fence barriers must follow the manufacturer’s instructions and ASTM F2286, with compliant hinged gates; they cannot be installed atop an onground pool. Keep the inside face at least 20 inches from the water. A pool screen enclosure used as a barrier must comply with §305.2 and be designed by a registered design professional; its barrier mesh requires at least 100 pounds per square foot tensile strength under ASTM D5034 and 150 pounds per square foot ball-burst strength under ASTM D3787. Such an enclosure is not a dwelling wall. Equipment on the same lot outside a pool barrier must stand at least 36 inches from its outside face.

PRIVATE RESTRICTIONS

Recorded covenants, association architectural review, private easements and boundary or maintenance agreements can affect the fence independently of city approval. Confirm the applicable private requirements and ownership before work. A boundary fence is not automatically jointly owned, and a neighbor is not automatically responsible for half its cost.

Texas Property Code §202.023 protects qualifying owners’ security measures, including perimeter fencing, while retaining specified association controls over fence type, access and drainage obstructions, driveway gates and front-building-line fencing. Excluded association classes, protection for maintenance of fences installed before September 1, 2025, and enhanced-security exceptions can change an individual case. Section 202.022 separately protects its defined safety-compliant pool enclosure. These provisions do not waive public requirements or easement rights. The linked statewide guide explains the conditions.

REVIEW AND ENFORCEMENT CONTEXT

Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:

• Permits and plans: New work, the limited minor-repair exemption, site plans, required district findings, electrical gates and engineering for taller walls or screens.

• Height and location: The actual front/side/rear area, qualifying taller-fence conditions, curb-based sight areas, courtyard and sport-court placement, and public-property encroachments.

• Drainage and pool safety: Recorded drainage rights, approved flow and maintenance access, regulated floodplain work, and the applicable current or existing-pool barrier requirements.

• Maintenance and private rights: Repair of covered street-facing or required fences, existing ownership and attachment rights, and separate private covenants. Government enforcement does not resolve a private boundary or cost-sharing dispute.
