FENCE RULES – BEXAR (COUNTY), TEXAS
OVERVIEW
This page covers residential fencing in unincorporated Bexar County. Incorporated cities administer their own fence rules. San Antonio Military Protection Areas and municipal extraterritorial plat or other specifically authorized review can affect particular unincorporated properties; county road, floodplain and drainage responsibilities remain separate.
Bexar County does not publish a general front-, side- and rear-yard fence-height schedule or a countywide list of ordinary wood, vinyl/PVC and chain-link fence standards. The main public checks are the fence’s location and effects on flooding, drainage, road access and recorded easements. Floodplain development review extends beyond the mapped floodplain: development in or within 100 feet of a special flood hazard area requires a county permit. Work in county-maintained road rights-of-way has its own permit. Rural homes also need to account for agricultural fencing and livestock rules, while private covenants can impose additional restrictions within Texas law. Updated November 2026.
| Quick question | Bexar County answer |
|---|---|
| Permit or approval | The county does not publish a separate general ordinary-fence permit requirement or exemption. Floodplain development in or within 100 feet of a special flood hazard area requires a permit; county-maintained right-of-way work requires a separate permit. |
| Typical fence height | No general county front-, side- or rear-yard ordinary fence-height schedule is published. Agricultural, pool and private restrictions have separate applicability. |
| Placement & property lines | No general numeric county fence setback from a private property line is published. Verify boundaries, recorded easements, road rights-of-way, drainage and flood conditions. |
| Common fence materials | Wood: no general county material-specific standard is published. Vinyl/PVC: no general county material-specific standard is published. Chain-link: no general county material-specific standard is published. |
| Important local conditions | Fence rules may be further affected by nearby flood hazards, drainage and utility easements, roads, military-protection-area conditions, pools, rural agricultural use and private restrictions. |

The table above is for quick reference. Additional fence-rule details appear in the corresponding sections below. 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 Bexar County Public Works Development Services or the responsible office identified for that issue.
GOVERNANCE
The Bexar County Commissioners Court adopts the county’s floodplain and subdivision regulations. Public Works Development Services administers applicable development, floodplain, stormwater and county-road review. The Floodplain Administrator determines how the flood regulations apply to the proposed site and work.
The county’s Public Works frequently asked questions describes unincorporated territory as having no specific land-use zoning, except for the identified San Antonio Military Protection Areas. Those areas have separate land-use compatibility and related controls. A property’s postal address alone does not determine municipal limits, a protection-area boundary or the authority responsible for a particular approval.
County-maintained road rights-of-way, drainage facilities and recorded subdivision easements can constrain a fence independently of ordinary yard design. Municipal plat responsibilities in an extraterritorial jurisdiction and special-district or utility interests must be evaluated for their actual territorial and functional scope. Environmental Services administers its public-health and code-compliance programs; private home-pool safety is a separate question from county floodplain review.
PERMIT AND APPROVAL REQUIREMENTS
• Ordinary fence approval: Bexar County’s published requirements do not communicate a separate general permit requirement or blanket exemption for an ordinary residential fence. The county’s site-based floodplain, road and applicable stormwater approvals remain relevant to the proposed work.
• Development in or near the floodplain: Article 3, Section C of the Bexar County floodplain court order requires a Floodplain Development Permit when developing property in or within 100 feet of a special flood hazard area. Obtain the required permit before starting fence-related development in that area. Public Works’ current permit guidance repeats the 100-foot proximity requirement.
• County-maintained road rights-of-way: A county right-of-way permit is required for all work within a county-maintained right-of-way and must be issued before work begins. The road dedication and responsible authority determine the corridor’s extent; the edge of pavement is not its boundary.
• Larger fence-associated clearing or grading: If the work disturbs at least one acre of soil, or is part of a common plan of development meeting that threshold, the county’s Storm Water Quality and Post Construction permit processes apply. The Storm Water Quality permit must be issued before soil disturbance. This is a land-disturbance condition rather than an acreage test for the residential lot itself.
• Private home pools: Confirm private-home pool barrier height, openings, gates and access protection with Bexar County Public Works Development Services and the responsible pool-safety office before choosing or replacing an enclosure. Association and multiunit-rental pool yards have a different statutory scope from a single-family backyard pool.
• Agricultural operations: Texas law protects qualifying agricultural operations and agricultural fences under conditions involving the operation’s use, location and the dates of the operation and governmental requirement. Existing state and federal duties remain. Agricultural acreage attached to a residence can qualify, but lot size alone does not establish an exemption. The linked statewide guide explains those conditions.
FENCE PLACEMENT RULES
• Boundaries and easements: The county does not publish a general numeric setback for an ordinary fence from a private property line. Establish the boundary and review the recorded plat, easements and any access or drainage dedications before placing posts. Existing fences, ditches, curbs and tax-map lines are not conclusive proof of ownership or the legal boundary.
• Road access and visibility: Keep fences and gates from obstructing public roads, roadside drainage, lawful access and the rights reserved in a dedication. A county road, state highway and private road can have different responsible authorities and recorded rights. Work in a state-highway right-of-way is subject to the applicable Texas Department of Transportation controls.
• Drainage and recorded subdivision conditions: Preserve drainage flow and maintenance access required by an easement, plat or approval. A fence or gate must comply with the actual recorded restriction affecting that strip. Texas Water Code Section 11.086 prohibits diverting or impounding natural surface water so that overflow damages another property.
• Development in or within 100 feet of a special flood hazard area: The floodplain order requires a demonstration that proposed development, together with existing and anticipated development, will not increase base-flood elevations outside the applicant-owned property included in the permit. Fence panels, debris accumulation, posts, footings and associated fill must be assessed for their effect on flood flow.
• Regulatory floodways: Article 5, Section E requires the applicable no-increase demonstration for flood levels during the base flood discharge. The order also provides a separate federal map-revision compliance route for an encroachment that would increase base-flood elevations. A fence in a floodway must satisfy the approved floodplain conditions before construction.
• Pipeline corridors: For fence work on or affecting a pipeline easement or right-of-way, notify the pipeline operator and complete the applicable construction-safety arrangements before work. Where protective work is required, the owner must pay its reasonable, necessary, documented cost before proceeding. Existing written agreements and statutory exceptions may control. This process is separate from an 811 locate request.
• Existing shared or attached fences: Except through mutual consent or the statutory process, a person may not remove a separating/dividing fence in which that person is a joint owner, or a fence attached to one owned or controlled by someone else. Texas Agriculture Code Sections 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 that owner’s land to require another attached fence’s disconnection. Those conditions do not create a six-month notice rule for every fence removal.
• 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. Protect the marks and dig carefully. Arrange separate identification of private lines that 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.
FENCE HEIGHT AND VISIBILITY RULES
Bexar County does not publish a general ordinary-residential fence-height schedule for front, side or rear yards in unincorporated territory. Applicable recorded restrictions, floodplain conditions, private covenants and special fence uses can determine the design for a particular property.
• Street corners and driveways: The county’s published ordinary-fence requirements do not supply a single numerical corner height or sight triangle for every existing residential lot. Preserve road visibility, lawful access and any applicable road or plat sight-area condition. A site-specific restriction may apply even where a general yard-height limit is not published.
• Rural cultivation and livestock: Texas agricultural fence standards apply according to the land’s actual use, the animal class and any applicable local stock-law election. Cultivated-land and livestock sufficient-fence standards are separate from ordinary yard-fence maximums. Determine that scope for the property before choosing an agricultural fence; the linked statewide guide explains the applicable height and construction branches.
• Private pool barriers: Use the required pool-safety height, opening and gate standards for the enclosure. Confirm those private-pool details with Public Works Development Services and the responsible pool-safety office. The six-foot enclosure definition in the Texas HOA statute concerns private-restriction protection, not a universal pool-barrier minimum.
MATERIAL AND CONSTRUCTION LIMITS
• Wood, vinyl/PVC and chain-link: The county does not publish a general ordinary-residential material-specific standard for these three fence materials. Applicable floodplain requirements, recorded conditions, utility rights and private restrictions still govern the location and design.
• Fences affecting drainage or floodwater: Solid panels, retaining walls, posts and footings must preserve the drainage and flood-flow conditions applicable to the property. Open fencing can also trap debris; an open design does not eliminate the required review or an easement restriction.
• Rural cultivation and livestock fencing: A rural residence with agricultural acreage may need a sufficient fence for cultivation or livestock under Texas Agriculture Code Chapter 143. Construction standards depend on the applicable stock-law territory, animal class and use. A local election’s coverage must be established before assuming either open-range treatment or a particular sufficient-fence standard.
PRIVATE RESTRICTIONS
Recorded covenants, HOA architectural review, private easements and boundary or maintenance agreements can affect the fence independently of county approval. Confirm the applicable private requirements and ownership before work. A fence on the boundary is not automatically jointly owned, and a neighbor is not automatically responsible for half its cost.
Texas Property Code Section 202.023 protects qualifying owners’ security measures, including perimeter fencing, while preserving specified association controls over fence type, access and drainage obstructions, driveway gates and front-building-line fencing. Its excluded association classes, pre-September 2025 maintenance protection 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 statutory 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:
• Floodplain and nearby development: Whether the fence project falls in or within the regulated proximity of a special flood hazard area, has the required permit, and meets the applicable no-increase and drainage conditions.
• Road and easement placement: Work within a county-maintained right-of-way, obstructions to roads or lawful access, and compliance with recorded drainage or utility interests.
• Associated site work: Stormwater approval where fence-related land disturbance reaches the applicable site or common-plan threshold.
• Special fence uses: Private-pool enclosures, agricultural fencing, underground-utility excavation and pipeline-corridor construction.
• Private restrictions and ownership: Association review and private boundary, maintenance and cost agreements are separate from county approval and remain subject to the Texas statutory limitations above.
