Summary
Knox County's Zoning Ordinance requires a written building permit from Code Administration and Inspections before erecting or moving any structure, and each accessory structure needs its own permit. Confirm whether your specific fence triggers a permit before you build.
Except as hereinbefore provided, a written building permit shall be obtained from the department of code administration and inspections before starting or proceeding with the erection, structural alteration, or moving of any building or structure, or changing the use of any building or land.
Full Breakdown
Section 6.10.01 requires a written building permit from the Department of Code Administration and Inspections before erecting, structurally altering, or moving any building or structure, with exemptions for interior finishes, agricultural and accessory farm buildings, and home gardening. Section 6.10.02 provides that each accessory building or structure requires a separate permit. Whether an ordinary residential fence triggers a permit depends on how the department applies these rules and the adopted building codes, so contact Knox County Code Administration directly. Fees double if construction starts before the permit is obtained. Inside Knoxville or Farragut, apply through the city or town.
Violations & Fines
Building without a required permit violates the Zoning Ordinance, subject to a $10-$500 civil penalty per Section 6.20.02 with each day a separate offense; permit fees are doubled if work starts first.
