FENCE RULES – GRIMES (COUNTY), TEXAS

OVERVIEW

This page applies to residential fencing in unincorporated Grimes County, outside incorporated cities, towns and villages. County floodplain, road, animal and nuisance controls have their own coverage. Subdivision authority can be allocated to a municipality in its extraterritorial jurisdiction without extending that municipality’s ordinary fence rules to every property outside its limits.

Grimes County does not administer general zoning in its unincorporated territory. Its fence guidance instead calls for notice before construction beside county-maintained roads, while fences in the floodplain fall under separate development approval. The county does not publish ordinary front, side or rear fence-height maximums or material-specific standards for wood, vinyl/PVC and chain-link. Road easements, drainage, recorded plat conditions and floodways can still control placement and design. Rural properties also have livestock and agricultural-law considerations; dog containment, certain abandoned-property pools and private association restrictions create additional conditions. Updated November 2026.

Quick question	Grimes County answer
Permit or approval	Notice is required for fence construction adjacent to county-maintained roads. A separate county Development Permit applies to fence work meeting the floodplain development definition; routine repair and other defined exclusions have their own limits.
Typical fence height	The county does not publish ordinary front, side or rear residential fence-height maximums. Conditional livestock, pool-nuisance and private-association provisions are separate from an ordinary yard-fence maximum.
Placement & property lines	No ordinary fence-specific numeric property-line setback is published. Actual road rights-of-way, drainage and utility easements, plat conditions, floodplain restrictions and access requirements can limit placement.
Common fence materials	Wood: no ordinary material-specific county standard published. Vinyl/PVC: not specifically addressed for ordinary fences. Chain-link: no ordinary material-specific county standard published. Site-specific containment, easement, flood and private requirements still apply.
Important local conditions	Fence rules may be further affected by county-road frontage, floodplain or floodway location, drainage and utility easements, continuing plat screening conditions, rural livestock and agricultural use, dog containment, qualifying abandoned-property pools and private restrictions.

GOVERNANCE

Grimes County Commissioners Court adopts county orders and regulations. The county does not administer general zoning in unincorporated territory, but it administers separately authorized development, floodplain, road, subdivision, animal-control and public-nuisance requirements. Fence responsibilities are distributed among those programs.

Development Services and the County Engineer administer applicable development and infrastructure requirements. The County Engineer or designee is also the Floodplain Administrator, reviewing development permits, necessary outside approvals and flood-hazard boundaries throughout unincorporated Grimes County. Road and Bridge handles fence-construction notice beside county-maintained roads and county-road easement concerns. TxDOT is responsible for state-highway and farm-to-market-road access approvals.

The county’s Infrastructure Regulations recognize subdivision arrangements under Local Government Code Chapter 242, specifically Navasota’s regulation of subdivision development in its extraterritorial jurisdiction. The county Model Rules retain their stated application throughout unincorporated territory regardless of that allocation. A subdivision arrangement does not itself make municipal yard-fence height or material rules applicable throughout the extraterritorial jurisdiction; determine the responsible subdivision authority for the actual tract.

The Sheriff’s Office/Animal Control Authority administers the county animal and stock-law provisions relevant here in unincorporated territory. Rabies provisions have separate potential incorporated-area coverage. The Environmental Department administers the county’s unincorporated public-nuisance policy. County or county-governed district land and easements can also have specific obstruction controls.

The county adopted the 2021 International Residential Code on December 18, 2024 under Local Government Code Chapter 233, Subchapter F. That program concerns new single-family houses or duplexes on vacant lots and covered residential additions. It does not establish an ordinary existing-property fence process.

PERMIT AND APPROVAL REQUIREMENTS

Separate the county’s road-adjacent fence notice from its floodplain Development Permit. An answer about one does not eliminate the other.

• County-maintained-road frontage: The Grimes County Development Services FAQ states that notice of fence construction is required adjacent to county-maintained roads only. Check with Road and Bridge before installing a fence along such a road so the actual public easement and proposed location can be addressed. The county describes this as notice, not a general fence building permit.

• Floodplain fence work: The Grimes County Flood Damage Prevention Order, approved January 21, 2026, expressly includes fences and fence-type structures in the floodplain within “development.” Article 3 requires a Development Permit for work meeting that definition throughout unincorporated territory. Related fill, grading, walls or drainage changes can independently bring a project within development review.

• Repair and definition exclusions: Routine maintenance and routine repairs are excluded from the development definition. For replacement work, the County Engineer or designee determines whether the actual project qualifies as routine repair. The definition also excludes certain agricultural activities that do not cause flooding or other impacts and insignificant activities, such as temporary storage in Zone X. Substantial-improvement and substantial-damage work remain within the definition.

• Application and plans: The owner or legal representative applies. The county application asks for a sketch or site plan showing the entire property and proposed development and considers both FEMA Flood Insurance Rate Map information and Base Level Engineering flood information. The flood order calls for applicable scaled plans in duplicate showing location, dimensions and elevations of proposed landscape alterations or structures relative to flood hazards, together with proposed watercourse or natural-drainage alterations. Supply the information relevant to the fence, wall, fill or grading project.

• Flood-related engineering and fees: County guidance requires signed and sealed professional-engineer plans for development in the floodplain. The application’s Zone A/Base Level Engineering 1-percent-flood branch lists a $103 permit fee and civil-plan/inspection requirements; its Zone X branch lists no permit fee, elevation certificate, civil plans or inspection. Classification and the actual project control the applicable branch. Building floor-elevation and floodproofing certifications are not fence-height rules, and a fence is not automatically a walled-and-roofed “structure” requiring a building-floor elevation certificate.

• Permanent electric service: If a gate or related development project requests new permanent electric service, the county’s January 21, 2026 electric-connection order requires a Certificate of Compliance before connection to a covered structure or development site. The order retains the applicable Public Utility Regulatory Act/Public Utility Commission provider exception. This service-connection condition is separate from ordinary fence-construction notice.

• Shared gated entrances: A qualifying gated community serving two or more dwellings not under common ownership has separate county emergency-access permit and hardware requirements. A homeowner changing such a common entrance must address those requirements with the County Engineer; this is a different situation from a gate serving one home.

• Other project approvals: A new or modified driveway can require the responsible road authority’s access approval. Construction affecting a pipeline easement has its own operator-notice and protection requirements, described below. Private association review is addressed separately under PRIVATE RESTRICTIONS.

FENCE PLACEMENT RULES

• Property boundaries: Grimes County does not publish an ordinary fence-specific numeric setback from a residential property line. Establish the legal boundary and applicable recorded restrictions before locating posts. A tax map, existing fence, hedge, ditch, mowing line or pavement edge does not establish the surveyed property boundary or public easement limit.

• County-road easements: The county FAQ explains that most county roads have 60-foot prescriptive easements for roads, ditches and utilities, and warns that an encroaching new fence may have to be removed at the owner’s expense. “Most” is not every road. Determine the actual legal easement; the statement is not a universal 30-foot-from-centerline fence setback.

• Drainage and utility easements: The county Infrastructure Regulations’ standard stormwater-drainage dedication requires the easement to remain clear of fences, buildings, plants and other obstructions to drainage-facility operation and maintenance, and states that abutting property is not permitted to drain into that easement. Apply the actual dedication to the property. Utility-easement locations and widths are determined for the relevant utilities and shown on the plat; there is no single countywide fence clearance or automatic right to build across an easement.

• Continuing plat screening: Double-frontage lots with rear or side frontage on a collector, arterial or thoroughfare can have denied-access plat notations and approved screening plantings or devices along that frontage. The county requires installation before road maintenance-period acceptance. Replacement work must preserve the lot’s continuing approved screening and access conditions.

• Driveways, corners and road access: County driveway location and spacing depend on the Mobility Plan and ultimate right-of-way. Review accounts for alignment, topography, drainage, stopping sight distance, vegetation and visibility. TxDOT handles state-highway and farm-to-market-road driveway approvals. A fence or gate must respect the actual access and visibility conditions at its location. The county does not publish a separate ordinary-fence corner-triangle measurement.

• Flood maps and site classification: The flood order uses the April 3, 2012 Flood Insurance Study and Flood Insurance Rate Maps, with revisions, together with Region 6 Base Level Engineering 1-percent-flood depth, elevation and cross-section information. It directs use of the basis providing the most impactful flood-risk reduction. Have the Floodplain Administrator determine the applicable mapped and engineering conditions for the site.

• Floodway and water-level limits: Article 4 B.9 addresses A1–30 and AE areas where a regulatory floodway has not been designated: cumulative development, including fill, must not increase the base-flood water surface by more than 0.1 foot anywhere in the community. Article 5 B separately uses a cumulative 0.1-foot limit for Zone A development or encroachment “within the floodway,” considering existing, proposed and anticipated watershed development. Article 5 E imposes the separate no-increase rule in a designated regulatory floodway, supported by hydrologic and hydraulic analysis. The order also contains a separate Article 4 B.10 provision for certain A1–30, AE and AH development causing more than a 1-foot increase only through the 44 CFR 65.12 process, and a conditional floodway-encroachment route under that federal process. A designated regulatory floodway remains subject to the no-increase rule and any applicable federal conditional-approval process. Obtain the applicable determination before locating a fence, wall, berm or fill.

• Flood-storage loss: Development or fill reducing storage in a Special Flood Hazard Area requires hydraulically equivalent 1:1 mitigation at or adjacent to the site, with zero net loss of natural storage. This matters when a fence-related wall, berm or grading project actually reduces flood storage; it is not a universal detention calculation for post holes.

• Drainage and grading: Water Code Section 11.086 prohibits diverting or impounding natural surface water so that overflow damages another’s property. Fence walls, footings, berms and grading must respect that rule. County development criteria prohibit uncontrolled sheet flow onto public rights-of-way or adjacent property. Covered grading or fill near a boundary requires construction-period grading or perimeter catchment to prevent drainage and sediment impacts, without increasing interim off-site flows above predevelopment conditions. Sediment controls follow the applicable Texas Pollutant Discharge Elimination System requirements; a stormwater pollution prevention plan is included when that permit is required. Ordinary post digging does not by itself establish such a permit requirement.

• Drainage nuisance: Filling or blocking a drainage easement, failing to maintain it, allowing debris, sediment or vegetation to clog drainage, or violating a county drainage-improvement or maintenance agreement can be a public nuisance under the county policy. These nuisance-policy grounds are subject to its statutory exclusions for qualifying state-permitted or regulated activity sites, Chapter 361 licensed facilities and agricultural land qualifying for appraisal under Subchapter C or D, Chapter 23, Tax Code. Independent floodplain requirements and recorded drainage-easement obligations retain their own scope.

• Joint or attached fence removal: Agriculture Code Sections 143.121–.123 prohibit removing a jointly owned separating/dividing fence or a fence attached to another person’s fence except by mutual consent or the statutory process. A person owning an interest in an attached fence may physically withdraw that fence after six months’ written notice to the other owner or that owner’s agent, attorney or lessee. An owner whose fence is wholly on that owner’s land may require an attached fence’s disconnection and withdrawal after the same written-notice period to the attached-fence owner or specified representative. This is not a six-month notice rule for every fence removal, and fence location alone does not establish joint ownership or automatic shared costs.

• Pipeline-easement construction: Health and Safety Code Sections 756.121–.126 cover construction on, across, over or under a pipeline easement or right-of-way, or work physically affecting or increasing pipeline risk; construction includes repair, replacement and maintenance. Subject to the statute’s contrary-written-agreement and other specified exceptions, notify the operator and satisfy the applicable route before proceeding: an operator determination of no increased risk, payment of reasonable necessary documented protective-work costs where risk increases, or an existing written agreement covering the work. It establishes no universal fence setback from a pipeline. An 811 ticket does not replace this construction-notice process or easement rights.

• Excavation exceptions and damage: Utilities Code Section 251.156 exempts activities performed on private property in connection with agricultural operations, defined as land activities described in Tax Code Section 23.51(2). A separate exception requires both an ownership, lease or mineral-leasehold interest in the property and operation of all underground facilities at the excavation site. The actual activities and facility operation control these exceptions. Emergency excavation requires reasonable care and prompt notice. Pipeline rules have their own applicability and exceptions. For damaged underground facilities, immediately notify the operator, or the notification system if the operator is unknown; only an authorized person repairs the facility. Delay backfilling until reporting is complete and the operator and excavator have agreed on the repair schedule. Keep ignition sources away where flammable material endangers life, health or property.

• Separate pipeline digging rules: Railroad Commission Chapter 18 can cover manual post digging deeper than 16 inches. Its default locate-ticket life is 14 working days, subject to a signed, dated written longer agreement; refresh unfinished work for the remaining area and retain required locate/response records for four years. Check the actual site, responses and marks, preserve the marks and use the rule’s second-notice process for missing or conflicting pipeline information. An unanswered first request is not automatic clearance. Use care within the pipeline tolerance zone, which extends 18 inches horizontally beyond each outside edge, and coordinate safe exposure and excavation with the operator. Report pipeline damage at the earliest practical time, no later than one hour, and leave it uncovered until the operator approves covering it. Notify 911 of a release and submit the applicable damage report within 30 days.

• Texas811 and post digging: Request a Texas811 locate before digging fence posts, including when planning shallow or manual digging. Utilities Code Chapter 251’s excavation definition covers mechanized or explosive earth movement 16 inches or more, including an auger. Ordinary statutory notice is no earlier than the 14th day before excavation and no later than the 48th hour before starting, excluding Saturdays, Sundays and legal holidays; a notice received before 11:59 a.m. on Saturday, as defined by Utilities Code Section 251.002(14), has a special earliest start of Tuesday at 11:59 a.m., or Wednesday at that time if the intervening Monday is a holiday. Follow the applicable ticket/start instructions and wait period, check notified operators’ responses and site markings, and resolve missing or conflicting information through the current ticket process. Private lines and facilities outside participating systems may need separate owner-arranged locating. Preserve marks and dig carefully; a ticket does not replace permits, easement rights or private review.

FENCE HEIGHT AND VISIBILITY RULES

Ordinary yard fences: Grimes County does not publish ordinary front, side or rear residential fence-height maximums, a general fence-height measurement method, a combined retaining-wall/fence limit or an ordinary post/column allowance. That does not override road, drainage, floodplain, animal-containment, plat or private requirements.

Visibility: The county does not publish a measured ordinary-fence sight triangle, but actual driveway access and stopping-sight conditions still matter, especially at corners, curves and gated entrances. The nuisance policy also addresses hazardous visual obstructions on county-owned land and on land or easements of a special district governed by Commissioners Court.

Purpose-specific dimensions: The livestock sufficient-fence specifications and conditional abandoned-property pool fence height below have different purposes and scopes. The six-foot pool-enclosure definition discussed under PRIVATE RESTRICTIONS concerns statutory association protection. None is an ordinary county yard-fence maximum.

MATERIAL AND CONSTRUCTION LIMITS

• Wood, vinyl/PVC and chain-link: Grimes County does not publish ordinary material-specific fence standards for wood or chain-link, and vinyl/PVC is not specifically addressed for ordinary fencing. No general county finished-side orientation, opacity, cap or retaining-wall/fence-combination standard is published. Material selection must satisfy applicable public easement, flood, containment, continuing screening and private requirements.

• Ordinary dog containment: County animal rules require dogs to remain securely on the owner’s property, or to be leashed under direct control or otherwise contained off the property. Restraint must be effective and humane, prevent departure, avoid danger to the dog and allow food, water and shelter. Animal Control may require more effective restraint if the existing method fails. For ordinary dogs, the county requires effective containment; the designated dangerous-dog enclosure requirements below apply separately.

• Designated dangerous dogs: An owner retaining a dog classified as dangerous must satisfy the county’s separate secure-enclosure requirements and provide proof, such as photographs/statements or Animal Control’s site inspection and determination. A secure enclosure is locked, prevents public entry including children and prevents escape or release; dangerous-dog marking and additional Animal Control enclosure conditions apply. The immediate restraint requirement is a secure enclosure or leash under direct control. The dangerous-dog designation and written Animal Control conditions determine the applicable enclosure requirements.

• Abandoned-property pools: Under the county nuisance policy and Health and Safety Code Section 343.011, a pool on abandoned AND unoccupied property IN a neighborhood must be protected by a fence at least 4 feet high with a latched AND locked gate, AND a cover over the entire pool that a child cannot remove. A neighborhood includes a platted subdivision or property contiguous to and within 300 feet of one; that distance defines the covered area, not a fence setback. The policy’s exceptions include qualifying state-permitted or regulated activity sites, Chapter 361 licensed facilities and agricultural land qualifying for appraisal under Subchapter C or D, Chapter 23, Tax Code. This conditional nuisance rule is not an ordinary occupied-home backyard-pool standard. Public/association pool requirements and protections for defined private pool enclosures have separate scopes.

• Grimes livestock stock law: The county’s animal order, effective September 13, 2011, records adopted stock law for horses, mules, jacks, jennets, cattle, hogs, sheep and goats. In unincorporated Grimes County, the relevant running-at-large prohibitions for those animals use the knowing-conduct requirements of Agriculture Code Sections 143.034 and 143.082.

• Agricultural sufficient-fence standards: Agriculture Code Section 143.028 states that a person need not fence against animals not permitted to run at large. Where its sufficient-fence provisions apply to livestock permitted at large, the fence must keep out ordinary livestock, be at least 4 feet high and meet the applicable type specifications: barbed wire with three wires, posts no more than 30 feet apart and one or more stays between every two posts; pickets no more than 6 inches apart; a board fence with three boards at least 5 inches wide and 1 inch thick; or a rail fence with four rails. A separate local-option election can establish three barbed wires without a board as a sufficient fence. These provisions operate within the adopted local-option area and animal-class framework. Section 143.077’s cattle-subchapter test concerns keeping out animal classes not affected by that subchapter. These are sufficient-fence standards for the covered animal and local-option circumstances, with site-specific public and private restrictions applying separately.

• Cultivated land and long fence runs: For cleared cultivated land outside the chapter’s adopted-stock-law treatment, Section 143.001 requires a fence at least 5 feet high that prevents hog passage. The adopted stock-law provisions govern the relevant Grimes animal classes. Section 143.002 separately requires an unlocked gate at least 10 feet wide when more than 3 lineal miles of fence around cleared cultivated land run in the same general direction.

• Livestock and roads: Agriculture Code Section 143.102 prohibits knowingly allowing the listed livestock to roam unattended on covered U.S. or state-highway rights-of-way; the chapter’s highway definition excludes numbered farm-to-market roads. The county stock law still matters on other roads. Section 143.003 has a narrow county-road condition: cattle are not considered running at large where the road separates two tracts under common ownership or lease and has a cattle guard authorized under Transportation Code Section 251.009 as part of both tracts’ fencing. The highway provisions preserve moving animals by herding, leading or driving; they do not authorize an unapproved road gate or cattle guard.

• Agricultural operations and improvements: Agriculture Code Chapter 251 protects qualifying agricultural operations and improvements under its actual definitions and timing conditions. For noncity governmental requirements, Section 251.005 generally applies a requirement where the operation began after it took effect, does not apply it where the operation began before, and preserves requirements already effective and applicable before the chapter’s effective date. The relevant effective date is when compliance was first required or attempted for that geographic area. City requirements do not apply to agricultural operations outside the city’s corporate boundaries. Qualification depends on the agricultural activities and statutory conditions applying to the operation.

• Qualifying agricultural fences: Section 251.006 protects construction or maintenance of a qualifying agricultural improvement, including a fence designed for sheltering, restricting or feeding animal or aquatic life or the specified agricultural storage/management purposes, when not expressly prohibited by statute or an applicable governmental requirement adopted consistently with Section 251.005 and in effect at construction. Its agricultural-land definition includes land qualifying for agricultural-use appraisal under Tax Code Chapter 23, Subchapter D, and other land where agricultural operations exist or may take place. State and federal statutory enforcement remains. Apply the protection according to the actual fence purpose, land status, operation dates and controlling requirements, alongside independently applicable flood, road, drainage and livestock duties.

PRIVATE RESTRICTIONS

Private HOA or property-owners’ association documents, deed and subdivision covenants, architectural requirements, conservation restrictions, private recorded easements, and boundary, maintenance or cost agreements can independently affect a fence. Their enforcement is subject to applicable Texas law. Public approval does not determine ownership, allocate fence costs or replace private review.

• Security fences and current HOA limits: Property Code Sections 202.022 and 202.023 limit particular association restrictions. Section 202.023 protects security measures, including perimeter fencing, but retains express controls. Its coverage excludes condominiums under Chapters 81 and 82 and Chapter 215 master mixed-use associations.

• Retained association controls: A covered association may regulate fence type; prohibit obstruction of license areas, public or community sidewalks and drainage easements or areas; require a driveway gate at least 10 feet from the right-of-way where the driveway meets a laned roadway; and, when a restrictive covenant provides, prohibit fencing in front of the dwelling’s front-most building line. The gate provision authorizes an HOA requirement; it is not a universal county setback or a maximum distance an association may require.

• Existing fences and security exceptions: Section 202.023 protects maintenance of perimeter/front-building-line fencing installed or constructed before September 1, 2025, notwithstanding its retained-control subsection. It does not expressly create an automatic replacement or expansion right. The exception to the front-building-line restriction applies when the owner’s residential address is exempt from public disclosure under state or federal law or the owner provides law-enforcement documentation of a need for enhanced security. That exception does not eliminate all other statutory controls or public easement duties.

• Defined pool enclosures: Section 202.022 protects a conforming enclosure around a pool, spa or water feature consisting of transparent mesh or clear panels in metal frames, designed not to be climbable and no more than 6 feet high. It must meet applicable state and local safety requirements. An association may regulate appearance and color within the statute, but may not prohibit its protected black transparent-mesh, metal-frame form. This is a statutory protection for a defined enclosure, not a county pool-barrier minimum or an ordinary yard-fence height cap.

REVIEW AND ENFORCEMENT CONTEXT

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

• Road frontage and access: Required notice, actual county-road easement encroachment, driveway access and location-specific visibility.

• Floodplain development: Whether a fence, wall, fill or grading project needs a Development Permit, relevant plans and engineering, and compliance with the applicable floodway, water-level and storage provisions.

• Drainage and public easements: Whether fences or associated work obstruct drainage, facility maintenance, an applicable dedication or required access, or cause prohibited off-site flow and sediment impacts.

• Containment and public-nuisance conditions: Ordinary dog restraint, separately designated dangerous-dog enclosure conditions, listed livestock stock law and qualifying abandoned-property pool protection.

• Replacement and excavation: Applicable joint/attached-fence consent or notice, utility-locate procedures and separate pipeline construction and damage-prevention duties.

Private association, covenant, ownership and cost disputes remain separate from county approval and public enforcement. The statutory association limits described above apply to the private review within their scope.
