Knox County's Zoning Ordinance sets no general height cap on residential fences, but a fence in any required front yard may not materially impede vision above 3½ feet. Near corners, a stricter visibility triangle rule limits obstructions between 2½ and 10 feet.
The Knox County Zoning Ordinance imposes no blanket maximum height for residential fences in side or rear yards. The height controls are safety-driven and apply to the front. Section 3.20.04.B bars any fence, wall, hedge, or yard ornament in a required front yard that materially impedes vision above 3½ feet. On corner lots, Section 3.20.04.A prohibits any fence or object obstructing vision between 2½ and 10 feet above the roadway crown within the visibility triangle. These rules govern the unincorporated county; inside Knoxville or Farragut the city or town zoning applies instead.
Zoning violations carry a civil penalty of $10 to $500 assessed by Code Administration and Enforcement, with each day a separate offense (Sec. 6.20.02); compliance may also be enforced by injunction.
