FENCE RULES – UNION CITY (CITY), TENNESSEE

OVERVIEW

Residential fences are permitted on private property within City of Union City, subject to local regulations. For properties located outside City of Union City municipal limits, Obion County regulates fences in unincorporated areas.

Fence rules for City of Union City appear primarily in the City’s Guidelines for Fences, the Union City Zoning Ordinance, the Union City Municipal Code, Planning & Codes Department materials, Building Codes and Building Requirements & Procedures materials, stormwater and land-disturbance materials, the 2018 International Residential Code, Tennessee residential jurisdiction status materials, and Tennessee 811 utility-notice materials.

This page focuses on typical single-family residential fencing. If the jurisdiction’s adopted code or ordinance materials do not state a specific limit or requirement, this page notes that the code does not specify one. If no local code or ordinance is available in the approved source packet, this page notes that the jurisdiction does not publish the relevant standard in the referenced published materials.

Compiled From the City of Union City Guidelines for Fences, Planning & Codes Department page, Building Codes page, Building Requirements & Procedures, Planning & Zoning page, Union City Zoning Ordinance, Union City Municipal Code, Stormwater Management page, Stormwater & Erosion Control Minimum Requirements, Land Disturbance Application, 2018 International Residential Code R105.2, Tennessee State Fire Marshal Residential Jurisdictions & Inspectors, Tennessee State Fire Marshal Residential Permit FAQs, Tennessee State Fire Marshal Residential Permits, Tennessee State Fire Marshal Currently Adopted Codes, and Tennessee 811 as of July 2026.

GOVERNANCE

City of Union City administers residential fence rules through the Planning & Codes Department, the Union City Zoning Ordinance, the Union City Municipal Code, building-code materials, stormwater materials, and related permit and inspection procedures.

City of Union City does not publish a single consolidated residential fence code. Fence rules appear in the City’s fence guidance, zoning provisions for yards, front yards, visibility, and fences, municipal-code provisions for private swimming pools and public-way obstructions, and stormwater and flood-hazard provisions where site conditions make those layers relevant.

City of Union City is listed as EXEMPT for Tennessee residential building-code enforcement, indicating local residential building-code administration. The City identifies the 2018 International Residential Code as its residential code for one- and two-family residential construction.

The Planning & Codes Department serves as the local point of contact for planning, zoning, stormwater, plan reviews, building permits, property maintenance, rental inspections, and fence questions within City limits.

PERMIT AND APPROVAL REQUIREMENTS

• Building-Code Permit Context: City of Union City is listed as EXEMPT for Tennessee residential building-code enforcement, indicating local residential building-code administration. 2018 International Residential Code R105.2 includes a building-permit exemption for fences not over 7 feet high. City of Union City does not publish a separate local building-permit requirement for standard residential fences.

• Front-Yard Zoning Compliance Permit: The City’s fence guidance requires a zoning compliance permit before installation of any front-yard fence. The application must include a site plan showing the proposed fence location and compliance with the City’s visibility and locational standards.

• Side and Rear Yard Fence Context: The referenced published materials do not explicitly state that a zoning compliance permit is required for standard side-yard or rear-yard fences. Side- and rear-yard fences remain subject to the City’s placement, visibility, right-of-way, drainage, easement, floodplain, stormwater, pool-barrier, utility, and private-restriction limits where applicable.

• Flood-Hazard Development Context: In the F-H Flood Hazard District and other special flood-hazard areas, the zoning ordinance requires permit review before development activity. Fence work that involves filling, grading, excavation, drilling, posts, or other site work in those areas is reviewed under the flood-hazard provisions.

• Stormwater and Land Disturbance: City stormwater materials state that all land-disturbance activities must obtain a no-cost land-disturbance permit. Projects disturbing 1 acre or more, or that are part of a larger development, must acquire a Tennessee Department of Environment and Conservation stormwater permit.

• Public-Way Excavation: Fence-related excavation in any street, alley, or public place, or tunneling under one, requires a city excavation permit before work begins, except where the Municipal Code separately addresses emergency underground-facility work.

• Private Swimming Pools: A private swimming pool that is larger than 250 square feet, deeper than 36 inches, and used with a single-family residence must be protected by a fence, mesh or better, at least 5 feet high with a controlled entrance. The Municipal Code also requires a building permit and location sketch for that pool.

FENCE PLACEMENT RULES

• Side and Rear Yards: Fences, walls, and hedges may be located in or along the edge of any side yard or rear yard, subject to visibility, right-of-way, drainage, easement, floodplain, stormwater, pool-barrier, utility, and private-restriction limits where applicable.

• Front Yard: A front-yard fence, wall, or hedge must be shorter than 30 inches and must be set back at least 10 feet from the outside edge of the street curb, or from the edge of street pavement where no curb exists, but in no case closer to the street than the property or right-of-way line.

• Property Lines and Rights-of-Way: The ordinance does not state a setback requirement for standard residential fences from side or rear property lines; however, fences must be located entirely on the owner’s property and must not encroach into rights-of-way or easements. The front-yard setback and right-of-way language above apply separately to front-yard fences.

• Retaining Walls: The zoning ordinance states that the front-yard fence and wall restrictions do not apply to retaining walls that are no greater than 30 inches above the centerline grade of the fronting street.

• Gates and Public Ways: Gates and doors may not swing open upon or over a street, alley, or sidewalk, and the Municipal Code restricts obstructions or materials that interfere with public streets, alleys, sidewalks, and rights-of-way.

• Drainage and Sidewalk Areas: The Municipal Code prohibits obstructing any drainage ditch in a public right-of-way and restricts vegetation or other obstructions that interfere with sidewalks or public ways.

• Floodplain and Stormwater Areas: Fence work involving fill, grading, excavation, drilling, land disturbance, drainage alteration, or work in a flood-hazard area is subject to the City’s flood-hazard and stormwater materials where those conditions apply.

• Utility Safety: Tennessee law requires notice through Tennessee 811 before excavation where the Tennessee Underground Utility Damage Prevention Act applies. For fence projects that involve digging, including digging, drilling, augering, boring, grading, or other movement of earth, notice generally must be given at least three full working days before excavation begins. Tennessee 811 is a notification center and does not mark lines itself; member utilities or their locators mark covered facilities, and the excavator must check the positive-response status before beginning work where required. This statewide utility-notice framework is separate from local fence permitting, zoning, development approval, easement limits, right-of-way approvals, floodplain review, stormwater review, drainage review, historic or design review, HOA restrictions, and other applicable requirements.

FENCE HEIGHT AND VISIBILITY RULES

• Front Yard Height: In any front yard, only fences, walls, and hedges shorter than 30 inches are allowed.

• Required Front-Yard Visibility: In a required front yard, no fence or wall may materially impede vision across the yard above 30 inches. Hedges or other vegetation may not materially impede vision between 30 inches and 10 feet above the ground.

• Street-Intersection Vision Clearance: At street intersections, the zoning ordinance restricts objects in the clear-vision triangle between 2.5 feet and 10 feet above the centerline grades of the intersecting streets. The triangle legs are 60 feet where no stop or yield controls exist, 22 feet on a stop- or yield-controlled street and 60 feet on the through street, or 22 feet on all approaches where all approaches are controlled.

• Side and Rear Yard Height: The code does not specify a maximum height for standard residential fences in side yards or rear yards. The 2018 International Residential Code building-permit exemption for fences not over 7 feet high is permit-exemption context only and is not a zoning maximum height.

• Pool-Barrier Height: A fence used to protect a regulated private swimming pool must be at least 5 feet high.

MATERIAL AND CONSTRUCTION LIMITS

• Front-Yard Materials: The City’s fence guidance allows only wood, stone, vinyl, and wrought iron for front-yard fences shorter than 30 inches.

• Side and Rear Yard Materials: The code does not specify permitted or prohibited materials for standard residential fences in side yards or rear yards.

• Pool-Barrier Construction: A required private-pool barrier must be a fence, mesh or better, at least 5 feet high, with a controlled means of entrance.

• Maintenance Context: Where City property-maintenance or rental-inspection standards apply, exterior structures such as fences and walls are reviewed for structural soundness and good repair.

PRIVATE RESTRICTIONS

Private restrictions operate independently from City of Union City fence rules. Subdivision covenants, HOA rules, deed restrictions, private easements, architectural-review covenants, conservation restrictions, agricultural agreements, boundary agreements, and recorded plats may impose more restrictive fence location, height, material, color, visibility, or approval requirements than the City’s published rules.

The referenced published materials do not state that City of Union City enforces private covenants or HOA restrictions as municipal fence rules.

REVIEW AND ENFORCEMENT CONTEXT

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

• Front-Yard Fence Review: A front-yard fence is reviewed through the required zoning compliance permit and site-plan submission for location, visibility, height, and material standards.

• Building-Code Permit Context: City of Union City is listed as EXEMPT, locally administers residential building-code enforcement, and identifies the 2018 International Residential Code as its residential code. The adopted code includes a building-permit exemption for fences not over 7 feet high.

• Front-Yard Limits: Front-yard fences, walls, and hedges are reviewed against the 30-inch height limit, the 10-foot curb or pavement-edge setback, the right-of-way line limit, and the front-yard material list.

• Visibility and Intersection Safety: Fence, wall, hedge, vegetation, and obstruction issues may be reviewed under the required-front-yard visibility rule and the street-intersection clear-vision triangle standards.

• Pool Barriers: A fence used to protect a regulated private swimming pool is reviewed separately from an ordinary yard fence because the Municipal Code requires a barrier at least 5 feet high with controlled entrance.

• Floodplain, Stormwater, and Drainage: Fence work involving flood-hazard areas, grading, fill, excavation, drilling, land disturbance, drainage ditches, stormwater controls, or public rights-of-way may be reviewed under the City’s flood-hazard, stormwater, drainage, public-works, or excavation provisions.

• Utility Safety: Fence projects involving digging or other earth movement are separately subject to Tennessee 811 notice and positive-response requirements where the Tennessee Underground Utility Damage Prevention Act applies.
