Full Breakdown
415(F)(1)(c) sets the baseline material rule for fences in residential districts and agricultural subdivisions: all portions of a fence must be built of the same or harmonious material, solid metal panel fencing is prohibited outright, and every vertical and horizontal support or cross member has to face the interior of the lot, so the finished side faces the street or neighboring property rather than the structural framework. Subsection (F)(1)(d) puts ongoing upkeep on the property owner, requiring the fence to be maintained according to all other County codes for the life of the installation.
415(G) then bans two specific materials by name in any R District yard: barbed wire and above-ground electrical fences are not allowed at all, with no exception carved out for agricultural or livestock uses inside those residentially zoned yards. 415(F)(2), meaning a fence can meet every height and setback requirement in the code and still be an outright violation if it is barbed wire or carries a live electrical current above ground. 415(F)(1)(d) folds maintenance into the same compliance obligation as original construction.
Violations & Fines
A fence built with barbed wire, an above-ground electrical charge, solid metal panels, or mismatched materials draws a written correction order from the Director of the Division of Planning and Zoning under Section 405.645. Refusing to remove or replace the fence after that order is served is a misdemeanor under Section 405.655, carrying a fine of up to five hundred dollars per day or up to six months in the County Jail, with each day the violation continues charged as a separate offense.
