FENCE RULES – MCKINNEY (CITY), TEXAS

OVERVIEW

This page covers single-family residential fencing within the incorporated City of McKinney, Texas, including homes in the Historic Overlay and residences on agricultural acreage.

McKinney requires a permit for a new fence and for changes in an existing fence’s height, location or material. Unchanged repairs are permit-exempt under the city’s residential guidance. Ordinary side and rear fences may reach eight feet six inches, while the Historic Overlay generally uses six feet eight inches. Front fences are limited to four feet and must be at least half open. A neighbor’s front yard, even across an alley, can change a side or rear fence’s height and design. Wood is recognized; vinyl/PVC is not specifically named; chain-link has location restrictions. Drainage, historic approval, retaining walls and pool enclosures need separate attention. Updated November 2026.

Quick question	McKinney answer
Permit or approval	A permit is required for a new fence or a change in height, location or material. An existing fence repaired without those changes does not require an ordinary fence permit. Agricultural zoning, historic review, retaining walls and pool barriers have separate conditions.
Typical fence height	Front: four feet and at least fifty percent open. Ordinary side/rear: eight feet six inches; Historic Overlay side/rear: six feet eight inches. Neighbor-front-yard, screening and approved-exception branches can change these limits.
Placement & property lines	Use the actual boundary, front building lines and neighboring-yard arrangement. Keep fences outside street/alley sight triangles and public property unless specifically authorized. Drainage easements, flood-flow paths and erosion-hazard easements have additional restrictions.
Common fence materials	Wood: recognized by the permit guidance and specified in one screening-related exception. Vinyl/PVC: not specifically named in Article 7; the standard-residential/approved-like-kind material rule applies. Chain-link: expressly addressed, but prohibited in ordinary front and specified adjacent-front-yard locations.
Important local conditions	Fence rules may be further affected by the Historic Overlay, neighboring front yards across alleys, required screening, planned-development and Town Center conditions, agricultural zoning, drainage and erosion-hazard easements, floodplain or positive overflow areas, retaining walls, pool barriers 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 McKinney Building Inspections or the responsible office identified for that issue.

GOVERNANCE

The City Council adopts McKinney’s development and construction regulations. Article 7 of the McKinney Unified Development Code contains the principal fence rules. The Chief Building Official interprets and administers that article, and Building Inspections processes fence permits and completion inspections. The Board of Adjustment hears administrative appeals and considers the specified fence-height special exceptions.

The Planning Department administers zoning and property-specific development conditions. Within the Historic Overlay, the Historic Preservation Officer and Historic Preservation Advisory Board administer the applicable Certificate of Appropriateness process. The Director of Engineering administers the relevant sight-distance, drainage and floodplain provisions. A fence can therefore satisfy its ordinary height limit while still needing another approval for its location or function.

McKinney’s current construction-code notices identify the 2024 International Codes as effective October 1, 2025. Residential construction and pool barriers follow the adopted codes with local amendments. The city’s separate fence-permit requirements remain applicable; a model building-permit exemption is not an exemption from Article 7.

For a property in a Planned Development district, the adopted Planned Development ordinance supplies its specific standards, with the general zoning standards applying where that ordinance does not state a different rule. McKinney Town Center and Regional Employment Center provisions can also affect an applicable residential frontage or approved development. Public zoning and plat conditions are separate from private association rules.

PERMIT AND APPROVAL REQUIREMENTS

• New fences and changed fences: The city’s residential fence-permit guidance requires a permit when there is no existing fence, or when the proposed work changes the existing fence’s height, location or material. If none of those features changes, the city treats the work as a repair that does not require an ordinary fence permit. Article 7 separately requires approval before fence construction, installation, alterations, additions or changes within its scope.

• Application and fee: The published residential fence-permit fee is $30. Submit the application and upload a site plan through Citizen Self Service. A survey or hand-drawn plan is acceptable. Show property lines, fence location, height, material, the fence builder and the house location. Article 7 also calls for the lot size and all improvements on the lot unless the information is already reflected on an approved site plan.

• Completion inspection: A permitted fence or wall must be inspected for compliance when complete. Notify Building Inspections on completion. The Chief Building Official accepts compliant work or requires modifications when it does not comply. A pool/spa enclosure is subject to pool-barrier requirements and inspection even when unchanged repair would ordinarily be exempt from a fence permit.

• Agriculturally zoned property: Article 7’s applicability provision excludes property in the AG Agricultural zoning district, while expressly retaining sight-visibility triangles in every zoning district. Pool, drainage, retaining-wall, easement and other independently applicable requirements remain relevant to the actual project. A residence on a large lot outside AG zoning does not receive this zoning-based exclusion.

• Retaining walls and engineered fence walls: The city requires a permit for every retaining wall, regardless of height. A retaining wall more than two feet high requires engineered plans. Separately, Article 7 requires a stone, masonry or brick wall more than four feet high to be engineered and designed, with plans sealed by a Texas professional engineer. A retaining wall supporting a fence must be considered with the fence’s location, height and drainage requirements.

• Historic approval and the residential exception: Article 7 states that a Certificate of Appropriateness must be approved before a fence permit is issued for property in the H Historic Overlay. Article 2, Section 204Z, expressly exempts fences that are not screening devices in the overlay’s Residential Area. It also exempts routine in-kind maintenance or repair that does not change design, material or outward appearance. The city’s historic-preservation fence guidance states more broadly that all new fences and changes in style, size or location require a Certificate of Appropriateness. These published statements differ in scope. Have the Historic Preservation Office and Building Inspections determine how the residential nonscreening exception applies to the proposed fence before work.

• When historic approval is required: For covered work in the Residential Area of the Historic Overlay, submit the property and applicant information, the property’s preservation-priority rating, photographs of the property and adjoining properties, a letter describing the work, and elevations or renderings. Provide material samples and additional information when requested. The Historic Preservation Officer may approve or approve with conditions; an application that cannot be approved is forwarded to the Historic Preservation Advisory Board for consideration within the published thirty-day process after a complete application. The residential procedure provides a twenty-one-day appeal period and a separate ten-day period after written denial for a hardship request.

• Height exceptions: A fence exceeding an applicable ordinary limit needs the specific Board of Adjustment relief described below. The separate six-foot wrought-iron option for certain neighboring-front-yard configurations depends on the Chief Building Official’s sight-distance and safety determination. Show the actual lot arrangement, neighboring building line, proposed construction and any claimed hardship rather than using the general rear-yard maximum for the whole perimeter.

• Floodplain and drainage work: Before beginning a project in a floodplain, the owner must submit the applicable floodplain application and obtain the development permit administered by the Director of Engineering. Fence construction must also satisfy Article 8’s specific flow-protection rule. A drainage-easement fence needs the city’s determination that it will not interfere with or impair natural water flow. Work involving grading, fill or changes to a drainageway requires the approvals applicable to that work.

• Pool enclosures: Residential pools follow the adopted 2024 International Swimming Pool and Spa Code, as locally amended, together with Article 7’s enclosure and inspection requirements. Have Building Inspections confirm the complete barrier design, openings, gates, access from the house and any proposed cover or alternative before altering a pool enclosure. Homeowners’ association and apartment-complex pools have a separate public-pool classification. Their requirements are not the ordinary private backyard pool rule.

• Agricultural operations: Texas law protects qualifying agricultural operations and agricultural fences under conditions involving the operation’s use, location and the dates of the operation and governmental requirement. Existing state and federal duties remain. Agricultural acreage attached to a residence can qualify, but lot size alone does not establish an exemption. The linked statewide guide explains those conditions.

FENCE PLACEMENT RULES

• Boundaries and building lines: Article 7 distinguishes the front building line, the property boundary and the adjoining lot’s front yard. Its side-yard rule applies along the side property line behind the front building line. A side or rear segment that faces a neighboring front yard can have the lower, open-fence limit described below, including when the properties are separated by an alley. Establish the legal boundary and recorded easements before setting posts; an existing fence, curb or map line is not conclusive boundary evidence.

• Street and alley intersections: No fence may occupy the sight triangle formed by measuring twenty feet back from a street-to-street intersection, or fifteen feet back from a street-to-alley intersection, along the intersecting property lines and joining the endpoints. Figures 7-2 and 7-3 show these triangles beside the property lines. The Director of Engineering may require additional sight distances when site conditions make them necessary for public health and safety. The triangle restriction applies in every zoning district, including AG.

• Public property and rights of way: A private fence, wall, screening device, guy wire, brace or other component may not be constructed on, or project over, public right-of-way or other city-owned property unless an agreement with the city authorizes it. Determine the legal right-of-way rather than measuring from the visible pavement alone. An ordinary fence permit does not replace the required agreement.

• Drainage and erosion-hazard easements: No fence may be constructed within a drainage easement unless the city determines that it will probably neither interfere with nor impair natural water flow across the easement. Where an erosion-hazard setback easement has been established, Article 8 prohibits fences, walls, decks, pools and other structures within that setback area. The applicable setback is established for the stream or channel and shown on the final plat. The limited city-trail exception is not a private-fence exception.

• Floodplains and positive overflow areas: Fences, including private fences and public screening, must not block or divert surface-water flow in a floodplain or positive overflow area. Within an effective flow area, a fence perpendicular to the direction of flow must have openings at least ten feet horizontally by one foot vertically, unless a flood study shows that the fence, assumed completely blocked, will not cause an adverse impact. This is a drainage-flow condition for those locations, not a citywide requirement for every yard fence.

• Existing drainage and surface water: Keep the existing drainage route and maintenance access in mind when adding a solid panel, masonry base, retaining wall or fill. Article 8 prohibits discharging construction materials and obstructing debris into the stormwater system. Texas Water Code Section 11.086 separately prohibits diversion or impoundment of natural surface water that damages another property by overflow.

• Regional Employment Center alleys: Where the Regional Employment Center development standards apply, Appendix 2C’s alley design provision requires buildings and fences to be set back at least three feet. Check the applicable zoning and approved alley layout before replacing a fence at one of those properties. This is a Regional Employment Center condition, not the ordinary citywide property-line setback.

• McKinney Town Center residential frontages: Where the Town Center residential-building standards govern the frontage, a residential structure set back ten feet or more from the front property line, with its slab or first floor less than eighteen inches above the sidewalk, must have a compliant low fence along the front property line. The same condition appears in Historic Core, Downtown Core, Downtown Edge, Transit Village Core, Transit Village Edge, Cotton Mill Core and Cotton Mill Edge. Preserve an applicable required frontage fence when replacing it; the ordinary front-yard height, openness and material requirements still matter.

• Approved subdivision screening and private streets: An existing required screening wall, perimeter feature or fence may carry continuing conditions in the approved development and recorded plat. In a private-street development, preserve required emergency, utility and governmental access. Special authorization for a development’s entry fence in an easement applies to that approved entry feature and includes utility-access and damage-risk conditions; it is not general permission for an individual lot fence in the easement.

• Pipeline corridors: For fence work on or affecting a pipeline easement or right-of-way, notify the pipeline operator and complete the applicable construction-safety arrangements before work. Where protective work is required, the owner must pay its reasonable, necessary, documented cost before proceeding. Existing written agreements and statutory exceptions may control. This process is separate from an 811 locate request.

• 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: Request a Texas811 locate before digging posts, follow the ticket’s lawful start time, check operator responses against site markings, and resolve missing or conflicting information before excavation. Protect the marks and dig carefully. Arrange separate identification of private lines that the service may not mark. Texas’ excavation-notice law and separate pipeline rules have different depth, tool, exception and ticket requirements; owning the yard does not establish a blanket exemption.

FENCE HEIGHT AND VISIBILITY RULES

• Ordinary front yard: The maximum is four feet, with at least fifty percent of the fence open for its entire height. Wire fences are prohibited in this residential front-yard branch. The same ordinary front limit applies within the Historic Overlay.

• Ordinary side and rear yards: A fence along the side property line behind the front building line, or in the rear portion of the yard, may ordinarily reach eight feet six inches. Within the H Historic Overlay, the corresponding ordinary maximum is six feet eight inches. The neighboring-front-yard and screening-device conditions below still apply.

• Midblock rear yard beside a front yard: Where a midblock lot’s rear yard adjoins another lot’s front yard, including across an alley, fencing along the side property line in front of the adjoining front building line is limited to four feet, must be at least fifty percent open for the full height, and may not be wire fencing. This branch applies both inside and outside the Historic Overlay.

• Corner side yard beside a front yard: Where a corner lot’s side yard adjoins another lot’s front yard, including across an alley, the segment along the side property line in front of the adjoining front building line has the same four-foot, fifty-percent-open, no-wire requirements. Figures 7-2 and 7-3 distinguish this arrangement from corner lots whose rear yards face each other.

• Other corner-lot arrangements: For a corner lot’s side yard adjoining a rear yard, rear yard adjoining a side yard, or rear yard adjoining a rear yard, including across an alley, the table allows eight feet six inches along the identified rear/side property lines. Within the Historic Overlay, the corresponding limit is six feet eight inches. The street/alley sight triangles remain fence-free.

• Wrought iron at the specified adjoining front yards: For the midblock rear-to-front and corner side-to-front configurations described above, Table 7-1 permits an increase to six feet when the fence is wrought iron and the Chief Building Official determines that it creates no sight-distance issue or safety concern. This is distinct from the Board of Adjustment’s general front-yard special-exception process.

• Fence beside a screening device: A fence adjacent to a screening device must be built at the same height as that device, whether the fence is parallel or perpendicular to it, unless a special exception is granted. The ordinary eight-foot-six-inch limit therefore does not automatically establish the height of a fence connecting to a required screen.

• Screening-related topographical exception: The Board of Adjustment may allow a fence or wall up to eight feet six inches beside a required screening device when unusual topography distinguishes the lot from similarly sized and shaped lots and creates a hardship that leaves privacy inadequate. The lot must have an existing residential structure or a permit for one, must be outside the Historic Overlay, and the subject fence may not be a corner-lot fence. The prescribed stained-wood or engineered masonry construction applies. Relief is limited to the fence sides meeting these conditions; the hardship may exist regardless of when the unusual condition was created.

• Six-foot front-yard special exception: The Board of Adjustment may approve a fence up to six feet between the front building line and public right-of-way. The property must be outside the Historic Overlay; the fence may not be a corner-lot fence; and an existing structure or a permit to construct one is required. The fence must remain at least fifty percent open for its entire height, and the Board must find the proposed six-foot fence consistent with and appropriate to the area.

• Historic side and rear special exception: The Board of Adjustment may allow a Historic Overlay side or rear fence up to eight feet six inches through either of two branches. One is unusual topography that distinguishes the lot from similarly sized and shaped lots and creates a hardship leaving privacy and security inadequate. Alternatively, the lot must have an existing residential structure or a permit for one, the fence must not negatively affect public health, safety or welfare, its design must complement other fences in the area, and its design, location and height must fit the area’s context.

• Grade and retaining walls: Show the proposed fence height and any retaining wall or grade change on the plans. Article 7 does not provide a separate fence-specific formula for sloping ground or a fence above a retaining wall. Building Inspections must apply the code to that configuration; the separate retaining-wall permit and engineering requirements remain applicable.

• Rural cultivation and livestock: Texas agricultural fence standards apply according to the land’s actual use, the animal class and any applicable local stock-law election. Cultivated-land and livestock sufficient-fence standards are separate from ordinary yard-fence maximums. Determine that scope for the property before choosing an agricultural fence; the linked statewide guide explains the applicable height and construction branches.

MATERIAL AND CONSTRUCTION LIMITS

• Standard and equivalent materials: Article 7 requires standard residential fencing material, or a like-kind material that the Chief Building Official determines has the same quality, appearance and durability. The city’s permit guidance expressly uses wood and wrought iron as material examples. A proposed alternative remains subject to the official’s equivalence determination and the restrictions for its particular location.

• Wood and vinyl or PVC: Wood is expressly recognized in the fence-permit guidance. Vinyl/PVC is not specifically named in Article 7’s material rule or the permit guidance’s examples; its treatment falls under the standard-residential or approved-like-kind material provision. Front-yard openness, historic review and any property-specific conditions still govern the proposed product and design.

• Chain-link and other wire fences: Article 7 expressly addresses chain-link. A chain-link fence less than five feet high in a residential district must have the finished edge at the top. Wire fencing is prohibited in the ordinary residential front yard and the specified midblock rear-to-front and corner side-to-front configurations. The separate front-chain-link exception is limited to industrial districts and public property.

• Electric fences, barbed wire and fence arms: An electrically energized fence is permitted by Article 7 only in the AG Agricultural district. Barbed wire and fence arms are limited to industrial districts or public property used to secure the specified public infrastructure and facilities, and they may not extend beyond the property line. Those provisions do not authorize barbed wire or fence arms for an ordinary residential yard.

• Construction for the screening-related exception: The eight-foot-six-inch special exception beside a required screening device requires either stained wood with board-on-board or double-sided construction, a stained trim cap and steel posts, or an engineered brick, stone or masonry wall whose color and style are consistent with and compatible with the surroundings. These specifications belong to that special exception rather than every ordinary wood fence.

• Masonry walls and enclosure access: Stone, masonry and brick fence walls over four feet require a Texas professional engineer’s sealed design. Every fence enclosure constructed under Article 7 must have at least one gate in its perimeter. A gate serving a pool enclosure must also meet the applicable pool-access safeguards.

• Historic design and changes: Where a Certificate of Appropriateness is required, the proposed fence is reviewed under the applicable historic approval criteria and approved design. The Residential Area’s ordinary-maintenance exception requires no change in design, material or outward appearance. Changing a wood fence to another product can therefore raise both the ordinary material-change permit requirement and the historic approval question.

• Continuous pool protection: Article 7 requires a pool, and an excavation intended to become a pool, to remain continuously enclosed during construction and after completion so that it is reasonably inaccessible to small children or animals. The stated exceptions concern government-controlled bodies of water other than swimming pools and bodies of water in natural drainageways. Pool plans must show enclosure compliance, and final pool inspection and approval are withheld until the requirements are satisfied. Maintain approved protection while a fence is being replaced and obtain Building Inspections’ determination of the current code’s barrier and gate details.

PRIVATE RESTRICTIONS

Recorded covenants, HOA architectural review, private easements and boundary or maintenance agreements can affect the fence independently of city approval. Confirm the applicable private requirements and ownership before work. A fence on the boundary is not automatically jointly owned, and a neighbor is not automatically responsible for half its cost.

Texas Property Code Section 202.023 protects qualifying owners’ security measures, including perimeter fencing, while preserving specified association controls over fence type, access and drainage obstructions, driveway gates and front-building-line fencing. Its excluded association classes, pre-September 2025 maintenance protection and enhanced-security exceptions can change an individual case. Section 202.022 separately protects its defined safety-compliant pool enclosure. These provisions do not waive public requirements or easement rights. The linked statewide guide explains the statutory conditions.

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 plan review: Whether the project is a new fence, an unchanged repair, or a change in height, location or material; whether the site plan is complete; and whether permitted work receives its completion inspection.

• Height and frontage review: The correct front, side, rear, midblock or corner-lot branch; adjoining front building lines across alleys; required screening; and the conditions of any approved height exception.

• Historic and development conditions: The Historic Overlay’s Residential Area nonscreening exception, the differing published approval instructions, any required Certificate of Appropriateness, and the actual Planned Development, Town Center or Regional Employment Center conditions.

• Location and drainage review: Street/alley sight triangles, public-property encroachment, easement access, erosion-hazard setbacks, floodplain permits and fences across effective flow or positive overflow areas.

• Materials, walls and pool enclosures: The proposed material and wire-fence restrictions, required engineering, retaining walls, enclosure gates, continuous pool protection and applicable pool-barrier inspections.

• Separate private and state duties: Private restrictions and ownership agreements remain separate from city approval. Applicable agricultural, utility, pipeline and shared/attached-fence duties depend on the actual property and work.
