FENCE RULES – CALDWELL (COUNTY), TEXAS

OVERVIEW

This page covers residential fences in the unincorporated areas of Caldwell County, Texas, including rural homes with agricultural acreage. Incorporated municipalities have separate authority. Municipal extraterritorial jurisdiction, airport hazard areas, recorded easements, road ownership and floodplain conditions can create different responsibilities for a particular property.

Caldwell County does not administer general county zoning and does not publish an ordinary yard-fence permit, height schedule or material list. A fence project can still involve county right-of-way approval, floodplain development review, drainage restrictions or a shared-access easement. Wood, vinyl/PVC and chain-link have no ordinary material-specific standard in the Development Ordinance. The location of the legal boundary and recorded corridors matters more than the apparent edge of a road or an existing fence. Rural agricultural fencing, pool use, underground utilities, attached fences and private restrictions add separate conditions. Updated November 2026.

Quick question	Caldwell County answer
Permit or approval	The county does not publish a general fence-specific permit requirement or exemption for ordinary residential fences. County right-of-way work and covered floodplain development have separate approval requirements.
Typical fence height	The Development Ordinance does not specify ordinary front-, side- or rear-yard fence maximums. Agricultural, pool, airport and private-restriction conditions have their own scope.
Placement & property lines	No general fence-specific property-line setback is specified by the Development Ordinance. Legal boundaries, rights-of-way, drainage and utility easements, and recorded joint-access areas remain separate constraints.
Common fence materials	Wood: not specifically addressed as an ordinary residential fence material. Vinyl/PVC: not specifically addressed. Chain-link: not specifically addressed by the ordinary residential provisions. Drainage, pool and private requirements can affect construction.
Important local conditions	Fence rules may be further affected by floodplain or floodway location, drainage and access easements, public rights-of-way, the San Marcos airport hazard area, pool use, agricultural operations, fence ownership or attachment, utility and pipeline work, 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 Caldwell County Sanitation/Development Services or the responsible office identified for that issue.

GOVERNANCE

Caldwell County Commissioners Court adopts the county’s development, road and floodplain requirements within its lawful jurisdiction. Caldwell County does not administer general zoning in its unincorporated territory. Its Development Ordinance addresses subdivision and site development, public infrastructure, access and related conditions.

Sanitation/Development Services, the County Planner and the County Engineer administer their respective development functions. The Director of Sanitation is the Floodplain Administrator under the 2026 Flood Damage Prevention Ordinance. The Unit Road Administrator handles work in county rights-of-way, while the Code Enforcement Department addresses county sanitation and development violations. A state highway, a private access easement and a county road have different controlling authorities.

Municipal extraterritorial jurisdiction: Subdivision and related development responsibilities depend on the applicable law, current territory and actual county-city agreement. An extraterritorial-jurisdiction location is not a countywide extension of a city’s ordinary fence code.

San Marcos airport hazard area: The City of San Marcos administers its airport hazard and surrounding-land-use ordinance in its applicable area. The county’s May 2026 memorandum of understanding provides for referral of qualifying county development applications in the mapped hazard area to San Marcos Planning and Development Services. The county need not forward applications within Martindale’s city limits or extraterritorial jurisdiction unless Martindale requests that referral in writing. Each government retains enforcement of its own requirements.

PERMIT AND APPROVAL REQUIREMENTS

• Ordinary residential fences: Caldwell County’s published requirements do not communicate a general fence-specific permit requirement or express exemption. The county’s residential construction application concerns dwelling construction, installation, additions and specified reconstruction. Separate approvals below depend on the work and its location.

• Floodplain development: The 2026 Flood Damage Prevention Ordinance applies to special flood hazard areas within county jurisdiction and adopts the June 10, 2026 Flood Insurance Study and maps, with revisions. Article 3(C) requires a Floodplain Development Permit for covered construction and other development in Zones A1–30, A99, AE, A, AH and AO, and development in Zone A on the applicable Flood Hazard Boundary Map or Flood Insurance Rate Map. Development includes excavation, fill, grading and other man-made changes. A fence project involving those activities in an applicable area needs its floodplain approval determined by the Floodplain Administrator before work begins.

• Floodplain application and site changes: For covered fence work, the Floodplain Administrator uses county application forms and project-appropriate scaled plans showing the fence and relevant locations, dimensions, elevations and landscape changes in relation to flood hazards. Describe any proposed watercourse or natural-drainage alteration. Associated crossings or changes affecting mapped flood conditions may require engineering, crossing review or a conditional or final map revision appropriate to that work. The flood ordinance preserves existing easements, covenants, deed restrictions and ordinances, and requires the stricter overlapping condition.

• Current floodplain application: When floodplain approval is required, use the county’s September 2026 Floodplain Application and checklist for the actual work. Supply the project/parcel and flood-map information, project-description letter, owner/applicant signatures, recorded deed, current fee and pre-development meeting date. The Floodplain Permit checklist also calls for a tax certificate showing taxes paid in full before January 31 of the current year. The responsible office determines the applicable technical submissions for the fence and associated site work. Submit a complete electronic PDF package to the form’s designated intake address by 12:00 p.m. Monday before the scheduled Tuesday intake meeting; incomplete applications may be rescheduled.

• Work in county public rights-of-way: Fence construction, repair or excavation actually within a county-jurisdiction street, alley easement or other public right-of-way requires the Appendix C permit and advance approval of plans/specifications by the Unit Road Administrator. Applicable plans identify the lot/address, existing right-of-way features and utility connections, with a traffic-control plan when required. Provide the required public-liability insurance certificate, unless already on file, in the amount specified by the permit form. A right-of-way work permit expires after six months unless extended in writing.

• During permitted county right-of-way work: Approved fence work must preserve access, coordinate affected utilities/infrastructure and maintain a safe site with required signs and barricades. Backfill excavations promptly. If that work disturbs pavement, permanent pavement repairs are due within three days after backfilling unless the Unit Road Administrator authorizes otherwise. Equipment or material storage in the right-of-way requires permission under the permit.

• Private-home pools and spas: The county does not publish a separate ordinary private-home pool-barrier dimension schedule in its residential fence requirements. Pool use and the applicable safety requirements govern the enclosure. Health and Safety Code Chapter 757 addresses specified multiunit-rental and property-owners-association pools; an ordinary single-family home outside a condominium project is excluded from that chapter’s multiunit-rental definition. Association and public-pool standards are separate from the ordinary private-home setting.

FENCE PLACEMENT RULES

• Property lines and recorded corridors: The Development Ordinance does not specify a general fence-specific setback from a private property line. The legal boundary, a building setback, a public right-of-way and a recorded drainage, utility or access easement are distinct. Deeds, plats, surveys and easement instruments identify the relevant property interests. Existing fences, tax-map lines, curbs, ditches and pavement edges are not conclusive legal boundary markers.

• Drainage facilities and easements: Appendix D requires applicable plat notes directing owners to keep drainage facilities and easements clear of fences, buildings, planting and other obstructions that affect water flow or operation and maintenance. County employees have drainage-easement access rights. The current county plat notes impose continuing owner maintenance at the owner’s expense, reserve governmental inspection and access, and permit recovery of remedial costs after an owner’s failure to maintain. Blocking, filling, obstructing flow or altering the easement requires express county approval and applicable municipal approval in an extraterritorial jurisdiction.

• Open-design drainage fences: The county’s September 2026 plat notes provide for open-design fences allowing free water flow, alongside specifically designed and approved storm-control structures. A drainage-area fence is subject to the applicable recorded easement, plat conditions and county determination, including the clear-flow and maintenance-access conditions. Covered floodplain and floodway work also remains subject to the separate permit and encroachment requirements.

• Flag-lot and other shared access: Appendix A.6(G) prohibits fences, walls and other obstructions within an area covered by the required Joint Use Access Agreement for adjoining flag-lot access stems. A fence or gate on an existing private-street access corridor must also respect the county, utility and emergency-access rights reserved by the applicable easement. Private-street provisions allow removal of barriers that impair that access.

• Public roads and gates: Public roads must remain clear of obstructions. Locate the actual right-of-way and preserve the relevant access and drainage rights before setting posts or locating a gate. County right-of-way construction approval applies within county jurisdiction; TxDOT administers state-road interests. The county does not publish a general ordinary residential gate setback measured from a curb, pavement edge or ditch.

• Regulatory floodways: Article 5(E) of the flood ordinance prohibits encroachments, including fill, construction and other development, in an adopted regulatory floodway unless standard-practice hydrologic and hydraulic analysis demonstrates no increase in flood levels during the base-flood discharge. Its separate route for an increase requires a conditional map and floodway revision and federal approval before the encroachment. A floodway variance cannot authorize an increase in flood levels during that discharge. These are conditions for actual floodway encroachments, including relevant fence site work.

• Flood areas without a designated regulatory floodway: For covered development in Zones A1–30 and AE, Article 4(B)(12) requires a demonstration that the cumulative effect of proposed, existing and anticipated development will not raise the base-flood water surface by more than one foot at any point in the community. Article 4(B)(13) provides a separate conditional-map-revision and federal-approval route for specified increases in A1–30, AE and AH. The Floodplain Administrator interprets necessary mapped-boundary questions, uses applicable flood data and addresses watercourse alterations and preservation of flood-carrying capacity.

• Surface water and slope-related work: Water Code 11.086 prohibits diverting or impounding natural surface water in a manner that damages another’s property by overflow, subject to the section’s stated water-control qualifications. Walls, footings and associated grading can affect that flow. In an applicable floodplain development review, excavation, fill or slope work must also satisfy the ordinance’s actual erosion and site-safety conditions. State construction-stormwater coverage concerns qualifying activity disturbing at least one acre, including work within a larger common plan; ordinary post holes alone are not a universal stormwater-permit trigger.

• Existing jointly owned or attached fences: Agriculture Code 143.121 prohibits removal, except by mutual consent or the statutory process, of a separating or dividing fence in which the person is a joint owner, or a fence attached to one owned or controlled by another person. Under Section 143.122, a person owning an interest in an attached fence may withdraw their fence from the other fence after six months’ written notice to the specified owner or that person’s agent, attorney or lessee. Section 143.123 separately allows the owner of a fence wholly on their land to require disconnection and withdrawal of another’s attached fence after six months’ written notice to its owner or agent, attorney or lessee. Ownership, physical attachment and consent determine which provision applies.

• Construction affecting a pipeline easement: Health and Safety Code 756.121–.123 covers fence construction, repair, replacement or maintenance on, across, over or under a covered pipeline easement or right-of-way, and work physically affecting or creating risk to the pipeline. Subject to contrary written agreements and the statute’s public-owner exceptions, notify the operator and satisfy the applicable path: the operator determines no increased risk; the constructor pays reasonable, necessary and documented protective-work costs before proceeding; or the work is under an existing written agreement. A locate ticket is separate from these construction duties. The statute establishes no universal numeric fence setback from every pipeline.

• Utility notice and pipeline excavation: Utilities Code Chapter 251 covers explosives or powered/mechanized excavation, including augers, disturbing soil to 16 or more inches. Give ordinary notice no earlier than the fourteenth day before excavation and no later than 48 hours before the start, excluding Saturdays, Sundays and legal holidays. A notice given on Saturday before 11:59 a.m. allows a following-Tuesday 11:59 a.m. start, or Wednesday 11:59 a.m. if the intervening Monday is a holiday. Follow the ticket’s start instructions. Specified private facilities and some water or sewer facilities have different coverage; private services may need separate locating.

• Agricultural excavation and separate pipeline rules: Utilities Code 251.156 has a notice exception for private-property activity connected with statutorily defined agricultural operations, and a separate exception for a qualifying property-interest holder operating all underground facilities at the site. Residential acreage alone does not establish either exception. Railroad Commission Chapter 18 separately excludes earth movement not exceeding 16 inches, so covered pipeline work can include deeper manual digging. Its ordinary ticket lasts 14 working days, unless extended by the permitted signed, dated written agreement; refresh unfinished work for the remaining area. Retain required ticket and positive-response records for at least four years. Within the pipeline tolerance zone—18 inches beyond each outside edge—exercise reasonable care; methods to consider include appropriate hand, soft or vacuum excavation. Other mechanical or technical methods require operator approval. The rules do not require hand digging or noninvasive methods for pavement removal.

• Before post digging: Request a locate through Texas811, wait the applicable lawful period and follow the ticket’s start instructions. Check responses and markings, resolve missing or conflicting information through the notification process, protect marks and dig carefully. Keep permits, property permission and pipeline-easement construction duties separate. Report underground-facility damage immediately to the operator, or through the notification center if unknown; do not make unauthorized repairs or backfill before reporting and agreement on repairs. For covered pipeline damage, notify the operator through the notification center as soon as practical, no later than one hour after the incident, and submit the required Railroad Commission report within 30 working days. For escaping gas or other immediate danger, move to safety and call 911.

FENCE HEIGHT AND VISIBILITY RULES

The Development Ordinance does not specify ordinary residential front-, side- or rear-yard fence maximums, an ordinary fence-height measuring formula, or a general fence sight-triangle dimension. Actual rights-of-way, shared access, drainage, pool use and private restrictions remain relevant to location and construction.

• Airport hazard area: San Marcos airport hazard elevations are measured relative to mean sea level. The airport ordinance preserves construction and maintenance up to 50 feet above the land surface from its airport height restrictions; that savings clause is not an ordinary county fence-height limit. Applicable airport requirements also address lighting, glare and electrical interference. Repair or replacement of an existing nonconforming airport hazard may not increase its height or navigation hazard. Federal aviation notice applies only when the actual federal notice criteria are met.

• Rural cultivated land: Agriculture Code 143.001 specifies a sufficient fence around cleared land in cultivation that is at least five feet high and prevents hog passage, subject to the chapter’s local-option stock-law exceptions. This is a conditional agricultural standard, separate from ordinary yard-fence maximums. Agriculture Code 143.002 also requires an unlocked gate at least ten feet wide when more than three lineal miles of fence run in the same general direction around cleared cultivated land.

MATERIAL AND CONSTRUCTION LIMITS

• Wood, vinyl/PVC and chain-link: The Development Ordinance does not specifically approve, prohibit or prescribe ordinary residential construction standards for these materials. It also does not publish an ordinary residential opacity, finished-side, decorative-post or cap schedule. Applicable drainage conditions, pool-barrier requirements and private restrictions can affect the design.

• Other materials and walls: The county does not publish a general ordinary residential fence-material schedule for masonry, composite, other metal, barbed wire, razor wire or electric fencing. No ordinary fence-on-retaining-wall height formula is specified by the Development Ordinance. A fence or wall must still satisfy any applicable public access, easement, floodplain, drainage or use-specific condition.

• Drainage-area construction: Where a fence is subject to the current plat note’s open-design condition, water must be able to flow freely. Recorded drainage conditions also protect maintenance access. The applicable recorded conditions, county determination and separate floodway controls govern that actual site.

• Rural agricultural operations: Agriculture Code Chapter 251 limits governmental requirements for qualifying agricultural operations and improvements, including agricultural fences. Under Section 251.005, a non-city political subdivision’s requirement applies to an operation established after that requirement became effective for its geographic area, and does not apply to an operation established before it. The section also preserves requirements already in effect and applicable to the operation before the chapter’s effective date. A city’s governmental requirement does not apply to a qualifying agricultural operation outside its corporate limits under Section 251.005(c).

• Agricultural improvement protection: Under Section 251.006, an owner, lessee or occupant of agricultural land is not liable to the state, a governmental unit or an owner, lessee or occupant of other agricultural land for construction or maintenance of an agricultural improvement when construction is not expressly prohibited by statute or a governmental requirement adopted in accordance with Section 251.005 in effect when the improvement was constructed. Such an improvement does not constitute a nuisance and is not otherwise subject to suit or injunction under that provision. Agricultural land includes land qualifying for agricultural-use appraisal and other land on which agricultural operations exist or may take place. Covered improvements include fences designed for sheltering, restricting or feeding animal or aquatic life; storing produce or feed; or storing or maintaining agricultural management implements or equipment. The section retains state and federal enforcement. Actual operation, use and timing conditions govern the protection; residential acreage alone is not a blanket exemption.

• Livestock and road frontage: Agriculture Code 143.102 prohibits knowingly permitting the listed livestock to traverse or roam unattended on a covered highway right-of-way. In Caldwell County, that provision’s highway definition covers U.S. and state highways and excludes numbered farm-to-market roads. Separate local stock-law and other applicable road requirements can govern other locations. Under Section 143.003, cattle on a county road are not considered running at large when the road separates two tracts under common ownership or lease and contains a cattle guard authorized under Transportation Code 251.009 that serves as part of both tracts’ fencing.

PRIVATE RESTRICTIONS

HOA covenants, deed restrictions, private architectural-review requirements, private easements and boundary, maintenance or cost-sharing agreements can impose independent requirements within Texas law. Public permits and recorded public drainage or access conditions remain separate. A fence’s location alone does not establish joint ownership or an automatic equal division of its cost.

• Perimeter security fences: Property Code 202.023 protects security measures, including perimeter fencing, subject to its retained association controls. It does not apply to condominiums under Chapters 81 or 82 or master mixed-use associations under Chapter 215.

• Controls an association may retain: Section 202.023(c) permits regulation of fence type; prohibitions on obstructing license areas defined by an agreement or plat, public or community sidewalks, and drainage easements or areas; and a requirement that a driveway gate be set back at least ten feet from the right-of-way where the driveway intersects a defined laned roadway. If a restrictive covenant provides for it, the association may prohibit fencing in front of the dwelling’s front-most building line. The gate provision is authority for an association requirement, not a universal county setback or a maximum distance.

• Existing fencing and enhanced security: Section 202.023(d) protects maintenance of perimeter fencing or front-building-line fencing installed or constructed before September 1, 2025, notwithstanding the subsection (c) controls. Section 202.023(e) separately limits the front-building-line prohibition for an owner whose residential address is protected from public disclosure, or who supplies law-enforcement documentation of a need for enhanced security. These protections have their stated maintenance, installation and security scope.

• Protected water-feature enclosures: Section 202.022 protects a qualifying nonclimbable enclosure of transparent mesh or clear panels in metal frames, no more than six feet high, around a swimming pool, spa or other water feature when it conforms to applicable safety requirements. Associations may regulate appearance and color within the statute, but may not prohibit the protected black transparent-mesh form in metal frames. Six feet is the definition limit for this protection, separate from an ordinary fence maximum or a pool-safety minimum.

REVIEW AND ENFORCEMENT CONTEXT

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

• County development and road review: Applicable right-of-way approval, recorded access rights, drainage flow and maintenance access.

• Floodplain review: Covered development, floodway encroachment, watercourse changes and the actual site conditions addressed by the flood ordinance.

• Special conditions: Applicable airport hazard controls, pool use, agricultural operation and livestock rules, underground excavation and pipeline-easement construction.

• Existing-fence and private matters: Statutory joint or attached-fence removal conditions remain public-law duties. Association review and private ownership, easement, maintenance and cost disputes have their own agreements and legal processes.
