FENCE RULES – MEDINA (COUNTY), TEXAS

OVERVIEW

This page covers county-administered residential fence requirements in unincorporated Medina County, Texas. Incorporated municipal territory is outside its scope. Within a municipal extraterritorial jurisdiction (ETJ), county floodplain and road functions remain distinct from city-administered subdivision or other approvals. Municipal fence codes and airport-specific land-use, hazard or design approvals are outside this county framework; properties subject to those programs need separate treatment.

Medina County’s published fence framework centers on floodplain development, roads and easements, recorded subdivision conditions and livestock control. The county subdivision regulations do not supply one ordinary yard-fence height, property-line setback or materials list. That leaves different questions for different sites: excavation in a flood-hazard area, encroachment into a public easement, an existing plat restriction, or a fence used to contain livestock can each change the answer. City subdivision administration can also apply in an ETJ. County approval, utility locating and private restrictions address separate parts of a project. Updated November 2026.

Quick question	Medina County answer
Permit or approval	Medina County does not publish a separate ordinary residential fence-permit requirement or exemption. Floodplain development and public right-of-way or easement encroachment have separate approval requirements.
Typical fence height	The county subdivision regulations do not prescribe ordinary front-, side- or rear-yard fence maximums. Pool use, agricultural fencing, recorded conditions and separately administered approvals need individual treatment.
Placement & property lines	The county subdivision regulations do not prescribe a fence-specific property-line setback. Public rights-of-way, easements, drainage and recorded plat conditions can limit placement.
Common fence materials	Wood: ordinary yard fencing is not specifically addressed by the county subdivision regulations. Vinyl/PVC: not specifically addressed. Chain-link: not specifically addressed.
Important local conditions	Fence rules may be further affected by municipal ETJ subdivision administration, public rights-of-way and easements, floodplain or floodway location, drainage, stock laws, pool use, utility and pipeline work, recorded plat conditions 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 the Medina County Environmental Health Group or the responsible office identified for that issue.

GOVERNANCE

The Medina County Commissioners Court adopts the county subdivision, floodplain and road measures discussed here. Its Commissioners Court regulations directory provides the February 10, 2025 Subdivision Rules and Regulations, municipal ETJ agreements, flood-damage-prevention order, stock-law proclamations and county-road cattle-guard specifications. These are separate regulatory programs, with different coverage and approval functions.

• County administration: The Environmental Health Group administers the published county floodplain development process and on-site sewage facility (OSSF) program. Commissioners Court handles subdivision action within county subdivision jurisdiction; precinct commissioners or their designees handle the published county road and encroachment approvals. The Texas Department of Transportation (TxDOT) administers the state-road access function identified in county plat requirements.

• Municipal ETJs: An ETJ is unincorporated territory with specified municipal powers. The county’s published agreements allocate subdivision plats and related permits to Castroville, Devine, Hondo and La Coste in their described areas. The Hondo agreement also contains a whole-property election where an ETJ boundary crosses an ownership tract. Present ETJ limits and any releases matter to the administering office.

• San Antonio ETJ: The published agreement generally uses county subdivision procedures, with city review for its specified residential tracts between 5,999 square feet and 0.4 acre, Texas Research Park parcels and county-requested review. The county receives applications and fees. The agreement separately retains county OSSF and floodplain authority and specified San Antonio/San Antonio Water System (SAWS) water-quality authority.

• Other municipal administration: Lytle also publishes subdivision proceedings involving its Medina County ETJ. Property-specific city administration must be established from the current boundary and applicable instruments. A mailing address does not determine the responsible government.

This page addresses the county functions described above. It does not establish municipal zoning coverage, airport-area boundaries or a local building/pool-code adoption for an individual property.

PERMIT AND APPROVAL REQUIREMENTS

Medina County’s published permit information does not specify a separate ordinary residential fence permit or an express fence-permit exemption. Its floodplain and road/easement approval requirements apply according to the location and work involved.

• Flood-hazard-area development: The county’s Flood Damage Prevention Court Order, passed January 30, 2020 and effective May 15, 2020, governs special flood hazard areas within the Commissioners Court’s jurisdiction. Development includes excavation, filling, grading and other man-made changes. The published county permit sheet requires a permit for development in the floodplain. The order adopts the May 15, 2020 Federal Emergency Management Agency (FEMA) study and maps, together with revisions.

• Floodplain application and commencement: The application goes to the Floodplain Administrator. The order provides for scaled location, dimensions and elevation information and a description of changes to watercourses or natural drainage. The currently linked form states that work may not start until the development authorization is issued; the permit is valid for one year and requires renewal if unfinished. Plans, maps and supporting approvals depend on the project. Foundation and OSSF certificate provisions apply to their stated construction and sewage contexts.

• Floodplain fee and subdivision compliance: The department currently lists a $45 floodplain development permit fee. Subdivision rule 3.4 conditions OSSF and floodplain permit issuance on subdivision compliance, with a branch for land divided before June 1, 1984 and a branch preserving the regulations applicable to a completed application received before the newer rules took effect.

• Public right-of-way or easement encroachment: Subdivision rule 8.7 requires a permit from the precinct commissioner or designee before driveway or utility construction, or other encroachment into public right-of-way or easements. A fence or gate project entering that space must address this separate approval.

• New or changed roadway access: County plat requirements identify a driveway permit for a lot’s access to a publicly dedicated road: the precinct road authority for county roads, or TxDOT for state roads. A project that changes the driveway or its access has this additional issue.

• Subdivision and special approvals: Creation or replatting of land has its own subdivision process and ETJ allocation. A standalone fence on an existing lot still needs to comply with applicable recorded conditions. Municipal building/fence processes, airport-specific approvals and any separately applicable pool requirements require their own governing authority and property coverage.

FENCE PLACEMENT RULES

• Property boundaries: The county subdivision regulations do not prescribe a fence-specific distance from an ordinary residential lot line. The legal boundary, road right-of-way and easement limits are different lines. Existing fences, pavement edges and ditches do not establish title or permission to use another owner’s land.

• Public roads and easements: The county encroachment permit requirement applies independently of an ordinary private-lot fence. Recorded plats and public or private easement instruments can preserve access or drainage corridors. Road ownership, dedication and county maintenance are separate: subdivision approval or road dedication does not itself mean the county has accepted maintenance.

• Drainage and floodplain sites: Subdivision rule 12.7 provides case-specific development review within floodplain or drainage easements. In the adopted regulatory floodway, the flood order prohibits encroachments, including other development, unless the prescribed hydrologic/hydraulic analysis establishes no increase in flood levels. The order retains the separate federal 44 CFR 65.12 process for qualifying proposed increases. Floodway review is distinct from ordinary property-line placement.

• Surface-water flow: Texas Water Code 11.086 prohibits diversion or impoundment of natural surface water, or permitting it to continue, in a manner that damages another person’s property by overflow, subject to the statute’s qualifications. Walls, fill and fence work that change runoff need to preserve lawful drainage.

• Designated subdivision Conservation Areas: Under subdivision section 9.7, the plat shows each Conservation Area’s boundary and type, and approved plat notes and covenants state its purpose and use restrictions. Within a designated critical-environmental-feature setback Conservation Area, section 9.7.5 requires a minimum 25-foot setback for construction or soil disturbance. A critical environmental feature outside the 100-year floodplain is also protected by an earthen berm diverting runoff around it. These are conditions of the designated Conservation Area.

• Designated Stream Corridor Conservation Areas: For a qualifying Stream Corridor Conservation Area under section 9.10, included in the subdivision’s average-lot-area calculation, construction and soil disturbance must remain outside the greater of the 100-year floodplain or the applicable setback from the stream centerline: 50 feet for drainage areas of 64–319 acres, 100 feet for 320–640 acres, and 200 feet for drainage areas above 640 acres. Drainage area measurements use the USGS 7.5-minute quadrangle map. The plat and applicable Conservation Area conditions identify the protected area and restrictions. These designated-area requirements are separate from ordinary lot-line fence placement.

• Existing jointly owned or attached fences: Under Texas Agriculture Code Chapter 143, removal of a separating fence in which the person is a joint owner, or a fence attached to another person’s fence, is subject to consent and the statutory process. Sections 143.122 and 143.123 contain different six-month written-notice procedures for withdrawing an attached fence or requiring disconnection from a fence wholly on the owner’s land. Section 143.122 applies to a person owning an interest in the attached fence; section 143.123 applies to an owner whose fence is wholly on that owner’s land. Each requires six months’ written notice to the attached-fence owner or that person’s agent, attorney or lessee.

• Pipeline easements: Covered construction on, across, over or under a pipeline easement, or work affecting pipeline risk, can fall under Health and Safety Code 756.121–756.126. Its operator notice, agreement and protective-work conditions depend on the statutory applicability and exceptions. Easement rights and that construction process remain separate from utility locating.

• Texas811 before post digging: Request a locate through Texas811 before digging fence posts, wait the applicable lawful period, check ticket responses and site markings, resolve missing or conflicting information through the ticket process, protect markings and excavate carefully. Utilities Code Chapter 251 covers specified mechanized excavation to 16 or more inches; its ordinary notice window is not earlier than the 14th day and not later than 48 hours before excavation, excluding Saturdays, Sundays and legal holidays, with a specific Saturday-notice branch. Under sections 251.002(14) and 251.151(b), a notice given to the notification center on Saturday before 11:59 a.m. qualifies for a Tuesday 11:59 a.m. start, or Wednesday 11:59 a.m. if the intervening Monday is a holiday. Applicable pipeline response requirements remain separate. Pipeline rules separately can cover manual work deeper than 16 inches. Locates may not cover private facilities. Pipeline ticket validity, renewal and records follow the applicable pipeline process; a locate does not replace permits, property permission or easement review.

FENCE HEIGHT AND VISIBILITY RULES

The county subdivision regulations do not prescribe ordinary front-, side- and rear-yard fence maximums, a fence-height measurement method, or a general residential fence sight triangle. Their road-design and building-line provisions address their stated road and building subjects. Recorded conditions, public road/easement limits and separately administered property-specific approvals remain relevant.

• Floodway and drainage locations: A fence’s obstruction of flow can matter independently of its height. The county’s floodway encroachment and drainage-easement review provisions described above apply to the actual work and mapped location.

• Agricultural and pool contexts: Agricultural sufficient-fence tests and pool-barrier requirements concern particular uses and legal categories. They are separate from an ordinary yard-fence maximum. A private single-family pool, an association pool and a multiunit/public pool require the correct classification and applicable safety requirements.

MATERIAL AND CONSTRUCTION LIMITS

The county subdivision regulations do not establish an ordinary residential fence-material schedule. Wood, vinyl/PVC and chain-link are not specifically addressed as ordinary yard-fence materials. Those regulations also do not supply a general yard-fence opacity, finished-side, razor-wire or electric-fence standard. Recorded conditions, agricultural duties, public easements, pool use and separately administered controls can affect a particular design.

• Livestock containment: The county currently publishes two August 31, 1945 stock-law proclamations following the August 25 election. After thirty days, they prohibited the listed animals from running at large throughout Medina County. One covers horses, mules, jacks, jennets and cattle; the other covers hogs, sheep and goats. Their species lists govern their scope. Agricultural fence sufficiency remains subject to the applicable Chapter 143 branch; these proclamations do not prescribe a universal yard-fence height or material.

• County-road cattle guards: The November 27, 2023 county-road specifications require a cattle guard at least roadway width and at least 16 feet wide, with an 8-foot length along the road. Subdivision guards must be 20 feet wide and use at least eight I-beams, 4 inches wide and 12 inches deep, with minimum 3/8-inch web and flange. The drawing requires removable wings and an owner-installed side gate at least 12 feet wide. These requirements concern the county-road cattle-guard installation.

• Cattle-guard construction details: The drawing specifies Class A concrete meeting ASTM C-94, structural steel meeting ASTM A-36 and black standard steel pipe meeting ASTM A-53; I-beams at 2-foot centers; and steel rail or black pipe spacing of at least 6 inches. It depicts 2-3/8-inch outside-diameter pipe, 6-by-6-inch timber posts or equivalent pipe, a minimum 3-foot foundation depth, and the detailed steel-plate/foundation assembly. For solid rock, the precinct commissioner may reduce the foundation to no less than 2 feet below the guard’s top. The adopted drawing controls the complete assembly.

• Pool enclosures: Health and Safety Code Chapter 757 applies to its defined multiunit-rental and property-owners-association pools and specified access openings. It does not provide one general private single-family backyard-pool standard. Municipal pool codes and county functions must be distinguished; the applicable pool classification and actual safety law govern a barrier used for pool protection.

PRIVATE RESTRICTIONS

Recorded covenants, architectural restrictions, private easements and agreements about fence ownership, attachment, maintenance or cost can apply separately from county approvals. Public permit approval does not determine ownership or settle a private boundary dispute. Texas law limits particular association restrictions.

• HOA perimeter security fences: Under Property Code 202.023, the security-measure protection excludes condominiums under Chapters 81/82 and Chapter 215 master mixed-use associations. The statute preserves authority to regulate fence type; prohibit obstruction of license areas, public/community sidewalks and drainage easements or areas; require a driveway gate at least 10 feet from the right-of-way where the driveway intersects a defined laned roadway; and, when provided by a restrictive covenant, prohibit fencing ahead of the dwelling’s front-most building line. The gate provision concerns HOA authority, not a universal public setback.

• Existing and enhanced-security fencing: Section 202.023(d) protects maintenance of perimeter/front-building-line fencing installed or constructed before September 1, 2025, notwithstanding the retained controls in subsection (c). Subsection (e) supplies an exception to the front-building-line prohibition for specified address-confidentiality or law-enforcement-documented enhanced-security circumstances. These provisions retain their particular conditions.

• HOA pool-enclosure protection: Section 202.022 protects a conforming, nonclimbable water-feature enclosure made of transparent mesh or clear panels in metal frames and no more than 6 feet high. Associations may regulate appearance/colors within the statute but may not prohibit its specified black transparent-mesh form. The definition’s height limit concerns this private-restriction protection; actual pool-safety law still applies.

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 floodway review: Whether excavation or other development needs county authorization, preserves drainage and satisfies the applicable floodway encroachment process.

• Road, easement and plat compliance: Whether the work enters public right-of-way or easements, changes roadway access, or conflicts with enforceable recorded plat conditions. The county subdivision rules identify categories of plat notes subject to county enforcement.

• Livestock and cattle-guard conditions: The listed stock-law prohibitions and the adopted county-road guard/gate installation specifications apply within their stated scopes.

• Separate authorities and private disputes: Utility and pipeline compliance, statutory jointly owned/attached-fence procedures, municipal administration and association restrictions involve different legal functions. Private ownership, maintenance and cost disputes remain distinct from county development approval.
