FENCE RULES – COMAL (COUNTY), TEXAS

OVERVIEW

This page applies to residential fence work in unincorporated Comal County. Properties inside incorporated municipalities have separate municipal requirements. Within a city’s extraterritorial jurisdiction (ETJ), subdivision review may be administered by the city or county under an agreement, while county floodplain, road and other programs can continue to apply.

Comal County does not administer general residential zoning. Its published requirements address particular conditions rather than one ordinary fence permit, yard-height schedule or property-line setback. Floodplain improvements, county road rights-of-way, recorded easements, private-road subdivision gates and animal containment can affect a project. Canyon Lake properties may also have federal land or flowage-easement restrictions. Wood, vinyl/PVC and chain-link are not universally classified as permitted or prohibited ordinary yard-fence materials; nuisance-screening provisions and particular easements need separate attention. HOA documents and state utility-location requirements also matter. Updated November 2026.

Quick question	Comal County answer
Permit or approval	County guidance does not publish a separate ordinary residential fence permit or blanket exemption. Floodplain work, road-right-of-way work, qualifying community gates and regulated lighting have separate requirements.
Typical fence height	No general county front-, side- or rear-yard residential fence maximum is published. Special-purpose enclosures and site conditions have separate requirements.
Placement & property lines	No universal numeric fence-to-property-line setback is published. County public rights-of-way, recorded easements, drainage and federal Canyon Lake interests can limit placement.
Common fence materials	Wood: no universal ordinary-fence classification. Vinyl/PVC: not specifically addressed as an ordinary fence material. Chain-link: no universal ordinary-fence classification; expressly recognized in a limited federal flowage-easement context.
Important local conditions	Fence rules may be further affected by floodplain or floodway location, Canyon Lake flowage easements, roads and drainage, recorded subdivision conditions, community entrance gates, animal containment, regulated lighting and private restrictions.

The table above is for quick reference. Additional 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 Comal County Engineer’s Office or the responsible office identified for that issue.

GOVERNANCE

Comal County Commissioners Court adopts county orders under specific Texas statutory powers. The county’s subdivision, floodplain, road, public-health and animal-control programs have distinct purposes and coverage. The Comal County Engineer’s Office administers subdivision regulations, county road-right-of-way approvals, floodplain development and environmental-health functions. The County Engineer is the county Floodplain Administrator. Environmental Enforcement handles the county’s nuisance program; the Sheriff’s Office administers animal control.

The Comal County Fire Marshal administers the County Fire Code and qualifying gated-community lockbox permits. The adopted 2024 International Fire Code framework addresses the public buildings, commercial establishments and multifamily dwellings with four or more units covered by the county order. A separate lockbox provision addresses defined gated communities and multiunit housing projects.

ETJ subdivision administration: The county’s subdivision regulations and interlocal agreements identify the following arrangements for the portions of each city’s ETJ in Comal County:

• Bulverde: The city administers subdivision review under consolidated provisions. The agreement preserves county administration for the listed Singing Hills, Unit 1; Singing Hills, Unit 2; and Kestrel Airpark, Unit 3 applications.

• Fair Oaks Ranch and Garden Ridge: Each city administers its subdivision regulations within its ETJ; the county agreements withdraw county subdivision enforcement there.

• New Braunfels: The city administers consolidated subdivision review. The county expressly retains floodplain, on-site sewage facility and driveway regulations in proposed and platted ETJ subdivisions.

• San Antonio: County subdivision procedures generally apply. Subdivisions containing habitable tracts smaller than 0.4 acre follow the city’s approval procedures under the agreement.

• San Marcos: The city administers subdivision review with incorporated county provisions.

• Schertz: The city administers subdivision review; the county expressly retains floodplain-development and septic permitting.

• Spring Branch: The county administers subdivision plats and related permits within the city’s ETJ. Incorporated Spring Branch remains outside this page’s ordinary scope, including where the County Engineer provides municipal floodplain administration.

These arrangements concern subdivision administration. Other requirements have their own territorial authority. Current corporate limits, ETJ releases, recorded plats and the applicable agreement determine the administrator for a particular property.

Canyon Lake: The U.S. Army Corps of Engineers separately administers federal land and federal flowage-easement interests. The Texas Department of Transportation (TxDOT) administers state-highway interests. The Texas Commission on Environmental Quality (TCEQ) administers applicable Edwards Aquifer and construction-stormwater programs. Private associations administer their own documents within Texas statutory limits.

PERMIT AND APPROVAL REQUIREMENTS

Ordinary residential fences: The county’s published permit guidance does not provide a separate fence-specific building or zoning permit requirement or a blanket exemption for ordinary residential fencing. The applicable project and site requirements below remain separate.

• Special flood hazard areas: Flood Damage Prevention Order 517 requires approval before erecting, constructing or altering an improvement, or placing material, in the regulated area. The county application requires a completed form, recorded ownership document, boundary drawing showing proposed improvements and a $40 application fee. Additional information depends on the proposal and flood conditions. A project without an associated septic application can obtain the county’s floodplain determination through the Floodplain Development Permit application.

• County road right-of-way work: A Private Improvement within the Public Right-of-Way (PIPROW) approval is required for covered driveway, landscaping and other ROW work. The process includes the application, site plan or survey, $25 fee, on-site review, a Permit to Construct before work and final inspection. Order 566 separately prohibits fencing within the county public right-of-way. PIPROW approval is an approval system for eligible improvements.

• Qualifying gated communities: County Fire Code Section 4.6 requires a Lockbox Permit from the Fire Marshal. A gated community is a residential subdivision or housing development with a pedestrian or vehicular gate and two or more dwellings not under common ownership. The separate multiunit definition covers apartment, condominium or townhome projects with two or more units. The incorporated state-law provisions apply outside municipal boundaries in areas not already subject to municipal gate regulations.

• Fence or gate lighting near Camp Bullis: Order 367 regulates applicable outdoor lighting in unincorporated territory within three miles of the Camp Bullis boundary. The County Engineer administers the lighting permit; the order specifies a $25 fee. Its lighting-specification exemptions and conditions appear below.

• Canyon Lake flowage-easement projects: Written-consent requirements depend on the actual federal easement and proposed work. The Corps’ published instructions differ concerning certain permeable fences at the government boundary. Establish the applicable consent requirements before construction.

FENCE PLACEMENT RULES

Property boundaries: No universal numeric county setback from a private property line is published for an ordinary residential fence. Establish the legal boundary and check the recorded plat and easements before setting posts. An existing fence, pavement edge, ditch or line on county mapping may differ from the legal boundary or right-of-way.

• County public rights-of-way: Order 566 states that fencing will not be permitted within the public right-of-way. County road drainage, side ditches and culverts must remain functional. The order also contains a general provision for pre-order improvements without permits that create neither a safety hazard nor drainage obstruction; its text does not expressly resolve how that provision applies to fencing.

• Dedicated utility and drainage easements: County subdivision provisions preserve utility installation, maintenance and access rights and prohibit interference within dedicated utility easements. Plat certifications require owners to maintain dedicated easements and avoid uses detrimental to their intended purpose. Drainage facilities require adequate space for operation, maintenance and access. The recorded instrument controls the affected location and rights.

• Surface drainage: Water Code Section 11.086 prohibits diversion or impoundment of natural surface water that damages another property by overflow, subject to its statutory qualifications. Fence bases, retaining walls, fill and grading can affect that flow. Health and Safety Code Section 343.011 separately treats filling or blocking a drainage easement, failing to maintain it, allowing it to clog with debris, sediment or vegetation, or violating a county drainage-maintenance agreement as a nuisance. That section excludes agricultural land qualifying for tax appraisal under Tax Code Chapter 23, Subchapter C or D, and sites or facilities permitted and regulated by a state agency, or licensed or permitted under Health and Safety Code Chapter 361, for the activity at issue.

• Floodplain and floodway property: County Order 517 regulates development in special flood hazard areas. In Zones A and AE without a designated regulatory floodway, new construction, substantial improvements and other development, including fill, require a demonstration that the proposed development, combined with all other existing and anticipated development, will not increase the base flood’s water-surface elevation. Within an adopted regulatory floodway, encroachments require the specified hydrologic and hydraulic demonstration of no increase in flood levels, subject to the order’s federal map-revision procedure. Watercourse alterations require the applicable engineering information and preservation of flood-carrying capacity.

• Canyon Lake federal boundaries and flowage easements: Federal fee land cannot be enclosed for private exclusive use. Flowage easements affect certain privately owned land near the lake. The Corps describes many easements by reference to the 948-foot elevation contour, but the actual easement may follow metes-and-bounds lines. The recorded federal acquisition and easement instruments determine the location. The Corps’ Canyon Lake adjacent-landowner guidance lists chain-link, wrought-iron, wire and other permeable fences built to or along the government boundary among flowage-easement activities allowed without written consent. Its application instructions also say work should await written consent. The Corps’ separate Government Owned Land guidance lists fences among restricted easement structures requiring an Easement Construction Permit in advance. These instructions conflict. Before planning or building, confirm with the Canyon Lake Project Office how the actual easement, fence location and proposed construction affect consent and approval for the parcel and project.

• Existing joint or attached fences: Agriculture Code Section 143.121 bars removal of a jointly owned separating/dividing fence or a fence attached to a fence owned or controlled by another person, except by mutual consent or as Subchapter F allows. Under Section 143.122, a person owning an interest in an attached fence may physically separate their fence from a fence owned wholly or partly by another person after giving six months’ written notice of the intended separation to the other fence owner or that owner’s agent, attorney or lessee. Under Section 143.123, a person whose fence lies wholly on that person’s own land may require an attached fence’s owner to disconnect and withdraw it after giving six months’ written notice of the required disconnection to the owner of the fence to be disconnected or that owner’s agent, attorney or lessee.

• Pipeline easements: Health and Safety Code Sections 756.122–756.123 require operator notice before covered building, repair, replacement or maintenance on, across, over or under a pipeline easement or right-of-way. Before proceeding, the operator must determine that the work will not increase risk to the public or pipeline facility, or the constructor must pay the reasonable, necessary and documented costs of protective work the operator determines is needed for increased risk. The statute also allows work under an existing written agreement and prompt disaster-related work required of a regulated utility. A contrary written agreement can govern applicability; the subchapter excludes qualifying noncommercial municipal work on municipally owned property and work on qualifying navigation-district or port-authority property.

• Texas811 before post digging: Request a Texas811 utility locate before digging, 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 generally covers mechanized excavation, including augering, to 16 inches or more. Notice ordinarily must be given at least 48 hours before work, excluding Saturdays, Sundays and legal holidays, and no earlier than 14 days before work. A Saturday notification has a specific Tuesday 11:59 a.m. start provision, shifted to Wednesday when the intervening Monday is a holiday. Follow the actual lawful start information. Private irrigation, pool and other customer-owned lines may need separate locating. Separate Railroad Commission of Texas (RRC) pipeline rules can cover manual digging deeper than 16 inches; their default ticket life is 14 working days, subject to a qualifying written longer agreement. Refresh unfinished work as required and retain required ticket and response records for at least four years. A locate does not replace permits, property rights or separate pipeline-easement requirements.

FENCE HEIGHT AND VISIBILITY RULES

Ordinary residential yard fences: Comal County does not publish a general front-, side- or rear-yard fence-height schedule, a universal fence/retaining-wall combination measurement or a numeric ordinary residential sight triangle. Road safety, easements, drainage, flood conditions and private restrictions can still affect a proposed fence.

• County road access: Driveway and ROW improvements must meet the county’s safety and drainage requirements. The Engineer’s Office can require a sight-distance or drainage study for covered access work. The legal right-of-way can extend beyond the visible road surface.

• Private-road subdivision entrance gates: Subdivision Section IV(C)(7) requires construction-plan details for gates at entrances or stub-street locations. The paved entry area outside the gates must provide a turning radius of at least 40 feet. This is a subdivision entrance requirement.

• Special-purpose enclosures: Dangerous-dog containment, covered pool facilities, abandoned-pool protection and nuisance screening have their own purposes and conditions. Their dimensions are separate from ordinary residential yard-fence maximums.

MATERIAL AND CONSTRUCTION LIMITS

Wood, vinyl/PVC and chain-link: The county does not publish a universal ordinary-yard material classification permitting or prohibiting these materials. Vinyl/PVC is not specifically addressed as an ordinary fence material. Chain-link, wrought iron, wire and other permeable fence types are recognized in the Corps’ limited government-boundary/flowage-easement guidance; project-specific consent requirements remain subject to the federal easement and administration.

• Nuisance screening: The county nuisance-enforcement provisions include Order 82’s separate screening standards. Section 1.09 specifies neutral or earth-tone materials and excludes doors, tongue-and-groove flooring, shipping crates or wooden pallets, interior-use materials, corrugated metal composite sheets, and cardboard or paper composite products. The order does not clearly state whether those screening standards apply to an ordinary residential boundary fence. The six-foot opaque-screening branch expressly concerns junkyards and automotive wrecking/salvage yards.

• Community gate access: Covered subdivision entrance gates require power-failure override and a master key or gate code for emergency services, school districts and law enforcement. For gated communities subject to the incorporated lockbox law, each vehicular gate needs an accessible exterior lockbox within sight and close proximity; at least one pedestrian gate needs one where pedestrian gates exist. The box must contain the appropriate key, card, code or override, with separately operated gates identified or covered by a master device. Electric gates must be openable without the normal access device during power failure.

• Emergency access in covered communities: At least one vehicular gate must accommodate emergency vehicles, and at least one entrance must be free of permanent obstacles that impede entry. Pedestrian gates must provide reasonable emergency access to each building. The state law contains a width waiver for qualifying multiunit projects completed before January 1, 2002 where space or excessive cost prevents compliance; it defines excessive cost using $6,000 per entrance in January 1, 2000 dollars. The law also limits specific county standards by the applicable ETJ municipality or nearest municipality and allows reasonable county standards where those municipal standards are absent.

• Pet containment: A physical fence used as restraint must keep the animal on the owner’s premises. The county animal order does not recognize wireless sound/shock containment as restraint. Dangerous-dog enclosures must be locked, prevent escape and entry by the public including children, be clearly marked and receive Animal Control approval. The owner must use the required leash control or approved secure enclosure.

• Private-home pools: A fence used to restrict pool access must be evaluated under the requirements applicable to that pool and property. The county does not publish an ordinary private-home International Swimming Pool and Spa Code (ISPSC) barrier specification in its permit guidance. Health and Safety Code Chapter 757 addresses specified association and multiunit-rental pools, while Texas Department of State Health Services (DSHS) public-pool rules use their own classifications. Those facilities have separate enclosure requirements.

• Abandoned and unoccupied neighborhood property: Current Health and Safety Code Section 343.011(c)(6) requires a swimming pool in this defined setting to have both a fence at least four feet high with a latched and locked gate and a full cover that a child cannot remove. A statutory neighborhood includes a platted subdivision and contiguous property within 300 feet. The section excludes qualifying agricultural land and sites or facilities covered by its state-permitting/regulation exceptions. Order 82 retains older six-foot-fence-or-cover wording; the order provides for legislative amendments and state-law priority. This condition concerns abandoned and unoccupied property.

• Lighting in the Camp Bullis zone: Regulated lighting must minimize glare and light trespass. Properly installed and maintained products approved by the International Dark-Sky Association (IDA) comply with the order’s specification. Article III exempts specified lighting from Article II requirements, including lighting in place before September 4, 2008; qualifying temporary lighting used for less than 14 days with at least 30 days before reuse; lighting for a single-family residence outside a platted subdivision; specified agricultural lighting; holiday lighting from November 15 through January 15; qualifying flag illumination; and pool/water-feature lighting governed by National Electrical Code Article 680. The lighting permit provisions address applicable installations separately.

PRIVATE RESTRICTIONS

Recorded deed restrictions, HOA architectural requirements, private easements and fence agreements can impose independent obligations within Texas law. County subdivision regulations expressly leave deed-restriction enforcement to the property owner, purchaser or landowners’ association. Public approval does not settle a private boundary, ownership, access or cost-sharing dispute. Agree on access, location, costs and future maintenance before shared work.

HOA security fencing: Property Code Section 202.023 protects security measures, including perimeter fences, while preserving an association’s authority to regulate fence type and prohibit obstruction of defined license areas, public/community sidewalks and drainage easements or areas. It permits an HOA driveway-gate setback of at least 10 feet from the right-of-way where the driveway intersects a defined laned roadway. A restrictive covenant may prohibit new fencing in front of the dwelling’s front-most building line.

The statute protects maintenance of perimeter/front-building-line fencing installed or constructed before September 1, 2025. It also protects qualifying address-confidentiality and law-enforcement-documented enhanced-security cases from the front-building-line prohibition. The section excludes the specified condominiums and Chapter 215 master mixed-use associations.

HOA pool enclosures: Section 202.022 protects a qualifying nonclimbable enclosure made of transparent mesh or clear panels in metal frames, no more than six feet high, that satisfies applicable safety requirements. Associations retain specified appearance/color controls but cannot prohibit the protected black transparent-mesh enclosure in metal frames. The six-foot definition concerns this statutory protection.

REVIEW AND ENFORCEMENT CONTEXT

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

• Engineer’s Office review: Floodplain improvements, county ROW work, drainage interference, easements and applicable subdivision conditions.

• Fire Marshal review: Lockbox and emergency-access requirements for qualifying gated residential developments.

• Environmental Enforcement and Animal Control: Applicable nuisance conditions, abandoned-pool protection and required animal containment.

• Federal and state interests: Canyon Lake government land and flowage easements, state-highway ROW, applicable environmental programs and utility/pipeline excavation duties.

• Private review and disputes: Association applications, deed restrictions, boundaries, fence ownership, attachment and private agreements follow their respective documents and laws.
