FENCE RULES – MONTGOMERY (COUNTY), TEXAS

OVERVIEW

This page addresses residential fences in unincorporated Montgomery County, Texas. Incorporated municipalities administer their own applicable rules; a city mailing address does not establish that a property is inside city limits. Municipal extraterritorial, subdivision and special-district authority can also depend on the parcel and the function involved. Updated November 2026.

Montgomery County’s ordinary fence decisions turn heavily on floodplain location, drainage and recorded property conditions. The county’s floodplain regulations expressly exempt fences outside the special flood hazard area from their development-permit requirement, while new fences inside that area generally need review unless a specific exemption applies. A replacement inside the floodplain qualifies only when it keeps the same size and materials. Those distinctions do not authorize a fence in a drainage easement or a barrier that worsens runoff. Rural properties also require attention to agricultural-operation protections, livestock duties and the separate rules for disturbing underground utilities or pipeline corridors.

Quick question	Montgomery County answer
Permit or approval	The floodplain development-permit exemptions cover fences outside the special flood hazard area, same-size/same-material fence repair or replacement inside it, and three-strand barbed-wire installation. Other site-specific approvals and drainage duties remain.
Typical fence height	The county does not publish a general front-, side- and rear-yard height schedule for ordinary residential fences in these unincorporated-area regulations. Private restrictions and special fence uses can determine the applicable height.
Placement & property lines	Check the boundary, recorded plat, easements and road right-of-way. Drainage easements must remain free of fences and other obstructions; floodway work has additional controls.
Common fence materials	Wood, vinyl/PVC and chain-link are not individually addressed by a general county residential fence-material schedule. Their suitability depends on drainage, any required approval, private restrictions and the fence’s purpose.
Important local conditions	Fence rules may be further affected by floodplain and watercourse location, grading, recorded subdivision conditions, drainage or utility easements, retaining walls, pools, agricultural operations and livestock.
Official local resource	Use the county’s Engineering review and drainage sign-off information to identify the review needed for the property and work.

The table is a quick reference. Read the applicable sections below and the linked official requirements before choosing materials or beginning construction, and confirm the property’s permit and drainage status with the Montgomery County Permit Department and Engineering Department.

GOVERNANCE

The Montgomery County Commissioners Court adopts the county’s development and floodplain regulations under the applicable Texas statutory authority. The Montgomery County Permit Department and Floodplain Administrator administer the floodplain development-permit system. The Engineering Department administers county drainage and subdivision engineering review. These are separate functions rather than a single city-style zoning approval.

The county’s Floodplain Management Regulations, effective October 1, 2025, apply in unincorporated county territory and define development to include installing fences. The Development Regulations, adopted March 4, 2025 and incorporating October 8, 2026 amendments, also govern applicable subdivision, drainage and related development conditions.

For an unincorporated parcel near a city, determine which office administers the relevant plat, road, drainage or development requirement. An extraterritorial subdivision arrangement does not, by itself, place every city fence rule on land outside the city. A special district’s drainage, utility or access rights must also be considered where its facilities or recorded interests affect the fence.

PERMIT AND APPROVAL REQUIREMENTS

• Floodplain development permits: The county regulations require a development permit before covered development in unincorporated territory, subject to their express exemptions. For a new fence inside a special flood hazard area, establish the applicable permit or exemption before work. The county may require scaled plans showing the work, existing improvements and flood-hazard relationship, along with the information needed to evaluate drainage and flood risk.

• Fence-specific exemptions: The county’s development-permit exemption sheet covers installation of three-strand barbed wire, repair or replacement of a fence inside the special flood hazard area when the replacement keeps the same size and materials, and fences and swimming pools outside the special flood hazard area. All exempt work must avoid silt runoff onto neighboring property and adverse effects on drainage on, from or through adjacent property. The Floodplain Administrator may require documentation or affidavits establishing eligibility, and other applicable regulations still govern.

• Associated clearing, grading and drainage review: A fence exemption does not automatically exempt accompanying clearing, excavation, fill or watercourse changes. Have the Engineering Department assess the entire project where those activities accompany the fence, where a watercourse is affected or where a county noncompliance notice applies. Separate exemptions for certain residential development or approved subdivision drainage plans do not create a general fence exemption. Maintenance of agricultural operations outside the special flood hazard area, including fence-line maintenance, has its own express development-permit exemption.

• Retaining walls: A retaining wall over four feet requires the Texas professional-engineer-sealed permit package specified by the county’s review form and construction certification by the engineer of record. The form states that County Engineering does not review or approve those wall designs. A fence attached to or placed above a retaining wall therefore needs a review of the wall as well as the fence.

• Agricultural operations: Texas Agriculture Code Chapter 251 limits county requirements by the dates of the operation and the requirement. A non-city governmental requirement applies to an operation established after the requirement took effect and generally does not apply to an operation established before it, while requirements already applicable before the chapter’s effective date are preserved. Qualifying agricultural improvements, including agricultural fences, have additional statutory protection when not expressly prohibited by statute or a valid governmental requirement in effect when constructed. State and federal statutes remain enforceable. A large residential lot alone does not establish this protection, and the county’s express fence exemptions should be considered separately.

• Private home pools: A pool fence has a safety function distinct from an ordinary boundary fence. The exemption for pools and fences outside the special flood hazard area concerns the county floodplain development permit. Confirm the actual private-pool barrier, gate and access requirements with the Montgomery County Permit Department before choosing the enclosure. Texas Health and Safety Code Chapter 757 governs specified association and multiunit-rental pool yards; its technical rules are not a universal substitute for the requirements of a private single-family pool.

FENCE PLACEMENT RULES

• Boundaries and recorded conditions: Establish the property line, road right-of-way, easements and any recorded plat conditions before setting posts. The location of pavement, a ditch, an old fence or the neighboring fence is not a dependable substitute for a boundary determination. County development approval does not resolve private ownership or disputed title.

• Drainage easements and access: County subdivision plat requirements call for drainage easements to remain clear of fences, buildings, vegetation and other obstructions that could impair drainage-facility operation and maintenance. Public agencies retain the access stated in the applicable dedication. A fence along a lot line must still remain outside a restricted easement, and a gate does not automatically cure an obstruction.

• Drainage and floodways: Avoid blocking swales, ditches, culverts or the route of runoff. Texas Water Code Section 11.086 prohibits diverting or impounding natural surface flow in a way that damages another property by overflow. In an adopted regulatory floodway, encroachments are prohibited unless the required hydrologic and hydraulic analysis demonstrates no increase in base-flood levels; the regulations contain a separate, tightly conditioned map-revision approval path. A development-permit exemption does not waive these substantive floodway controls.

• Road corridors: Keep fences and gates from obstructing a public road, ditch, driveway access or the rights reserved in the road dedication. County-road and state-highway rights-of-way may extend beyond the visible traveled surface. Work affecting a county road belongs with the county road authority; work in a state-highway corridor requires the applicable Texas Department of Transportation review. There is no single pavement-based setback that resolves every property.

• Pipeline corridors: Before building, replacing, repairing or maintaining a fence affecting a pipeline easement, right-of-way or pipeline safety, notify the operator and satisfy the applicable Texas Health and Safety Code construction requirements. Unless an existing written agreement or statutory exception controls, the operator must determine that risk will not increase, or the owner must pay the reasonable, necessary and documented cost of required protective work before proceeding. An ordinary locate ticket does not replace this separate process.

• 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: Contact Texas811 before digging fence-post holes and arrange separate identification of private lines the locate process may not mark. Utilities Code Chapter 251 covers powered or explosive excavation, including augering, at least 16 inches deep. Generally, give notice no earlier than 14 days and no later than 48 hours before work, excluding Saturdays, Sundays and legal holidays; follow the applicable ticket’s start instructions. Agricultural and owner/lessee exceptions have specific conditions, and owning the yard alone is insufficient. Railroad Commission Chapter 18 separately covers regulated pipeline excavation, including manual digging deeper than 16 inches, subject to its own exclusions. Verify the location, markings and operator responses, use the second-notice process when required, preserve marks and use appropriate safe exposure methods. The normal pipeline ticket lasts 14 working days unless extended by a signed, dated written agreement; required tickets and responses generally must be retained for four years. Neither a permit nor a locate request replaces pipeline-easement construction approval.

FENCE HEIGHT AND VISIBILITY RULES

Montgomery County does not publish a general ordinary-residential front-, side- and rear-yard fence-height schedule in its unincorporated-area development and floodplain regulations. A proposed height still needs to satisfy the parcel’s recorded conditions, any applicable approval, road-access constraints and the fence’s special purpose. The six-foot privacy-fence provisions for specified new commercial and subdivision development are development-screening requirements, not a minimum height for every homeowner’s yard fence.

• Road and driveway visibility: Design the fence and gate to maintain visibility and access at the actual road, driveway and intersection. Resolve the right-of-way and any site-specific dedication or engineering condition with the responsible road authority rather than assuming that an unincorporated address permits a tall opaque fence at every corner.

• Rural cultivation and livestock: Texas Agriculture Code Chapter 143 supplies conditional agricultural fence rules rather than residential zoning maxima. Subject to its local-stock-law provisions, a gardener or farmer must enclose cleared cultivated land with a sufficient fence at least five feet high that prevents hog passage. Where Section 143.028 applies, its four-foot sufficiency standard and construction specifications concern livestock permitted to run at large; Section 143.077 has a separate animal-specific sufficiency test. The relevant animal class, election territory and actual use must be established before applying one of these branches.

• Pool barriers: Determine the required barrier height and openings for the actual private-pool installation with the Permit Department. Neither a typical privacy-fence height nor the six-foot definition in the Texas HOA pool-enclosure protection establishes the pool’s safety minimum.

MATERIAL AND CONSTRUCTION LIMITS

• Wood, vinyl/PVC and chain-link: These materials are not individually addressed by a general county ordinary-residential fence-material schedule. Choose a design that preserves drainage and required access and meets any private covenant, recorded condition or project approval. Open construction does not automatically authorize installation in a drainage easement.

• Barbed wire and agricultural construction: Three-strand barbed-wire installation has an express county floodplain development-permit exemption. That exemption does not settle private restrictions or the livestock fence’s legal sufficiency. Where Agriculture Code Section 143.028 applies, the minimum four-foot fence has type-specific standards: three barbed wires on posts no more than 30 feet apart with at least one stay between posts; pickets no more than six inches apart; three boards at least five inches wide and one inch thick; or four rails. An additional local-election provision addresses three barbed wires without a board. Cleared cultivated land cannot be enclosed by more than three lineal miles of fence running generally in the same direction without an unlocked gate at least ten feet wide.

• Livestock containment: Local stock laws are animal- and territory-specific. Confirm the applicable election or proclamation for the property’s location and livestock before relying on a fence-sufficiency standard or assuming the land is open range.

• Walls, gates and flood effects: Solid walls, grade changes and fence footings must not create damaging impoundment or obstruct drainage. Retaining-wall engineering and the separate floodway review described above can control the design. A special floodplain permit exemption is not a materials approval or permission to obstruct another property’s drainage.

PRIVATE RESTRICTIONS

Recorded deed restrictions, subdivision architectural requirements, private easements, conservation restrictions and written boundary or maintenance agreements can affect a fence independently of county approval. Check the recorded instruments and obtain any required association review. A fence on a boundary is not automatically jointly owned, and a neighbor is not automatically responsible for half of its cost. County approval does not decide those private questions.

Texas Property Code Section 202.023 generally prevents a property owners’ association from enforcing a restrictive covenant that prevents an owner from installing security measures, including a perimeter fence. The section excludes condominiums governed by its specified definitions and master mixed-use associations subject to Chapter 215. An association may still regulate fence type, prohibit obstruction of a license area, public/community sidewalk or drainage easement/area, require a driveway gate to be set back at least ten feet from the right-of-way when it intersects a laned roadway, and, if a restrictive covenant provides for it, prohibit fencing in front of the dwelling’s front-most building line.

The 2025 amendments allow an owner to maintain perimeter fencing or fencing in front of the front-most building line installed or constructed before September 1, 2025, notwithstanding those listed controls. The front-building-line prohibition also cannot bar installation by an owner whose residential address is legally exempt from disclosure or who provides law-enforcement documentation of a need for enhanced security. That latter protection overrides the front-line restriction, not every retained fence-type, access or drainage control. These provisions do not themselves waive county requirements or establish a right to enlarge an existing fence.

Section 202.022 separately protects a defined nonclimbable water-feature enclosure made of transparent mesh or clear panels in metal frames, no more than six feet high, when it satisfies actual state or local safety requirements. Associations may regulate appearance and colors but cannot prohibit the qualifying black transparent-mesh enclosure in metal frames. This protection does not establish the safety code for every pool.

REVIEW AND ENFORCEMENT CONTEXT

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

• Permit and exemption conditions: Whether a proposed fence or replacement falls within the applicable floodplain development-permit requirement or a documented exemption, and whether related clearing, grading or retaining-wall work needs separate review.

• Placement and drainage: Obstruction of a drainage easement, road corridor or access right; damaging runoff; and floodway encroachments or unresolved site violations.

• Special uses and construction: Pool enclosures, agricultural fencing and operation protections, and utility or pipeline construction duties within their actual legal scope.

• Ownership and private review: Shared or attached-fence removal and association or private-agreement disputes require their own legal or contractual analysis. County permit approval does not settle private ownership or replace association review.
