FENCE RULES – UNICOI (COUNTY), TENNESSEE
OVERVIEW
Residential fences are permitted on private property within Unicoi County, subject to local regulations. This page applies to properties in the unincorporated areas of Unicoi County; incorporated municipalities such as Erwin and Unicoi may regulate fences under their own ordinances.
Unicoi County does not publish a consolidated residential fence ordinance in the referenced published materials. Fence-related context is framed by the County’s official government pages, the Tennessee State Fire Marshal residential-jurisdiction status materials, Tennessee residential permit materials, and statewide Tennessee 811 utility-notice requirements.
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 Unicoi County Government Website, Unicoi County Mayor’s Office, Unicoi County Commission, Unicoi County Road Superintendent, Tennessee State Fire Marshal Residential Jurisdictions & Inspectors, Tennessee State Fire Marshal Residential Permits, Tennessee State Fire Marshal Residential Permit FAQs, Tennessee State Fire Marshal Currently Adopted Codes, and Tennessee 811 as of July 2026.
GOVERNANCE
Unicoi County governs fence-related matters for properties in the unincorporated county through its county government structure. The Unicoi County Government Website identifies county offices including the Unicoi County Mayor’s Office, Unicoi County Commission, and Unicoi County Road Superintendent, but the referenced published materials do not identify a county planning, zoning, building, inspections, or code-enforcement office that publishes standards for standard residential fences.
Unicoi County does not publish a consolidated residential fence code, zoning ordinance, local building-code chapter, fence-permit form, or county fence standard in the referenced published materials.
The Tennessee State Fire Marshal Residential Jurisdictions & Inspectors list identifies Unicoi County as OPT OUT for Tennessee residential building-code enforcement. Erwin and Unicoi are listed separately as EXEMPT, so this county page does not apply inside those incorporated municipalities.
PERMIT AND APPROVAL REQUIREMENTS
• Residential Building-Code Status: Unicoi County is listed as OPT OUT for Tennessee residential building-code enforcement. The County does not publish a local residential building-code framework for unincorporated county properties, and the state-adopted IRC fence-permit exemption is not stated as an operating Unicoi County permit rule.
• State Residential Building Permit Context: Because Unicoi County is listed as OPT OUT, the State Residential Building Permit framework is not identified as the operating county building-permit program for standard residential fence work in unincorporated Unicoi County.
• Fence Permits: Unicoi County does not publish a local fence permit requirement for standard residential fences in unincorporated areas.
• Zoning Approval: Unicoi County does not publish a county zoning permit, zoning approval, zoning certification, or development-approval requirement for standard residential fences in unincorporated areas.
• Incorporated Municipalities: Erwin and Unicoi are listed separately by the Tennessee State Fire Marshal Residential Jurisdictions & Inspectors list. Properties inside those municipal limits are outside the scope of this county page.
FENCE PLACEMENT RULES
• County Placement Standards: Unicoi County does not publish county setback, yard-location, corner-lot, driveway-visibility, property-line placement, or standard residential fence location requirements in the referenced published materials.
• Rights-of-Way and Road Context: The referenced published materials do not publish a county right-of-way, easement, encroachment, drainage, culvert, driveway, or road-approval standard specifically for standard residential fences.
• 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
• Fence Height: Unicoi County does not publish a county maximum height standard for standard residential fences in unincorporated areas.
• Visibility Standards: Unicoi County does not publish a county sight-triangle, clear-vision, corner-lot, driveway-visibility, alley-visibility, or intersection-visibility standard for standard residential fences in unincorporated areas.
• Building-Code Height Context: Unicoi County is listed as OPT OUT under the Tennessee residential building-code framework, so the state-adopted IRC fence-permit exemption is not stated as a county maximum fence height or a county fence-permit trigger for standard residential fences.
MATERIAL AND CONSTRUCTION LIMITS
• Fence Materials: Unicoi County does not publish county material restrictions for standard residential fences in unincorporated areas.
• Fence Orientation and Construction: Unicoi County does not publish a county finished-side, opacity, chain-link, barbed-wire, electric-fence, wall, gate, pool-barrier, or fence-construction standard for standard residential fences in unincorporated areas.
PRIVATE RESTRICTIONS
Private restrictions operate separately from county rules. Subdivision covenants, deed restrictions, HOA rules, private easements, agricultural agreements, boundary agreements, architectural-review covenants, conservation easements, or other private restrictions may impose fence limits even where Unicoi County does not publish a county fence permit, zoning approval, height limit, placement standard, or material standard.
REVIEW AND ENFORCEMENT CONTEXT
Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:
• Jurisdictional Location: Whether the property is in unincorporated Unicoi County or inside an incorporated municipality such as Erwin or Unicoi.
• Residential Building-Code Status: Unicoi County is listed as OPT OUT under the Tennessee residential building-code framework.
• No Published County Fence Permit: Unicoi County does not publish a local fence permit requirement for standard residential fences in the referenced published materials.
• No Published County Standards: Unicoi County does not publish county height, placement, visibility, material, or construction standards for standard residential fences in the referenced published materials.
• Utility Excavation: Fence installation involving digging, drilling, augering, boring, grading, or other earth movement remains subject to Tennessee 811 notice requirements where the Tennessee Underground Utility Damage Prevention Act applies.
