FENCE RULES – SUMNER (COUNTY), TENNESSEE
OVERVIEW
Residential fences are permitted on private property within unincorporated Sumner County, subject to local regulations.
Residential fence regulations in unincorporated Sumner County are designed to facilitate property security while ensuring public safety, maintaining traffic visibility, and protecting public infrastructure. These standards are primarily codified in the Sumner County Zoning Resolution and apply to all residential districts. The county distinguishes between side/rear yard privacy fencing and front yard fencing, requiring specific transparency standards for fences located within the front setback to preserve motorist sightlines. All installations must be positioned to respect the public right-of-way and ensure the long-term stability of the structure.
Compiled From the Sumner County Zoning Resolution and the Sumner County Subdivision Regulations as of February 2026.
GOVERNANCE
The administration and enforcement of fence standards in the unincorporated areas of the county are managed by the Sumner County Department of Building and Codes and the Sumner County Planning and Engineering Department. Technical construction standards are governed by the locally adopted International Residential Code (IRC). Regulatory interpretations regarding placement and height are established by the Sumner County Regional Planning Commission, with the Board of Zoning Appeals serving as the body for granting variances or hearing appeals.
PERMIT AND APPROVAL REQUIREMENTS
• Standard Permit Exemption: The county lists a building permit exemption for the construction of a residential fence that is seven (7) feet or less in height.
• Height Permit Requirement: Any residential fence or wall structure exceeding seven (7) feet in height requires a formal Building Permit and must adhere to structural safety standards.
• Zoning Compliance: Building permit requirements are separate from zoning, setback, or plat requirements. Confirm any applicable zoning conditions, setbacks, and plat requirements with Sumner County Planning and Engineering Department before construction.
• Retaining Walls: Any retaining wall over four (4) feet in height must be designed and sealed by a Tennessee Professional Engineer.
• Floodplain Development: Construction of a fence within a designated Special Flood Hazard Area or Floodway requires specific review and a Floodplain Development Permit to ensure the structure does not impede the natural flow of water.
FENCE PLACEMENT RULES
• Public Right-of-Way: Fences and walls must be erected entirely outside of the public right-of-way of any public or private road.
• Easement Obstruction: Fences and walls are not permitted in utility easements unless approved by the utility provider in writing.
• Drainage Easements: Installation within a drainage easement requires the written consent of the County Engineer.
• Utility Clearances: A minimum of five (5) feet of clearance must be maintained from all sides of an electrical transformer or pedestal, except the padlocked side of a transformer, which requires ten (10) feet of clearance.
• Construction Standards: All fence posts and supports must be set into the ground to a minimum depth of two (2) feet to ensure long-term stability.
• Utility Safety: Tennessee’s Underground Utility Damage Prevention Act (TCA 65-31-101) requires everyone who digs to contact Tennessee 811 at least three (3) working days’ notice before starting a project. Tennessee 811 processes the notification of proposed excavation and notifies our member utilities, or their contract locators, to mark their underground facilities prior to the excavation.
FENCE HEIGHT AND VISIBILITY RULES
• Side and Rear Yards: In residential districts, fences and walls may not exceed eight (8) feet in height when located in the side or rear yards.
• Front Yard Height: Fences up to eight (8) feet in height are permitted in front yards; however, any fence located within the required front yard setback must be of transparent construction (e.g., split rail, picket, or chain link).
• Measurement Standard: Height is measured from the finished grade to the top of the individual fence sections. Measurements may not be taken from the top of a man-made berm.
• Intersection Visibility: On corner lots, no fence, wall, or vegetation may be placed or grown in a manner that impedes the vision triangle at the intersection of public or private streets.
• Driveway Safety: Fences must not interfere with clear vision at any driveway or alley exit such that the sight of oncoming vehicular or pedestrian traffic is impaired for users of such ingress or egress.
MATERIAL AND CONSTRUCTION LIMITS
• Prohibited Materials: The use of solid plywood, scrap lumber, paper, cloth, canvas, or other insubstantial non-customary materials is strictly prohibited.
• Masonry Standards: Walls made of common concrete or cinderblock are prohibited unless they are finished with a masonry material.
• Retaining Wall Restrictions: Wooden materials, including railroad crossties, are prohibited for use in retaining walls.
• Structural Orientation: Fences must be positioned so that all support posts, wood framing, and cross members do not face the street.
• Security Exclusions: Above-ground electrified fencing and barbed/razor wire are prohibited in residential districts, except when used for the purpose of enclosing livestock for a legitimate agricultural use.
PRIVATE RESTRICTIONS
Homeowners Association (HOA) covenants and private deed restrictions operate independently of Sumner County government. These private agreements often impose stricter standards regarding fence height, color, and allowable materials than the County resolution. Sumner County does not enforce private subdivision covenants; property owners are responsible for ensuring compliance with their specific neighborhood rules, which function as legally binding civil contracts.
REVIEW AND ENFORCEMENT CONTEXT
Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:
• Transparency Violations: Installation of an opaque (solid) fence exceeding the safety height within the required front yard setback.
• Vision Hazards: Reports of a fence or wall obstructing the vision triangle at a street intersection or driveway.
• Right-of-Way Encroachment: Construction of a fence within the public road right-of-way or over a dedicated utility easement without written consent.
• Maintenance Deficiencies: Fences found in a deteriorated condition, including broken components or structures that are substantially less than perpendicular to the grade.
