Full Breakdown
Mesa City Code § 8-6-3(I) bars three things outright: erecting or maintaining "any electric fence"; attaching "to any fence such items as glass, nails, metal objects, or other materials in such a manner that is likely to injure any person who comes in contact with such object"; and erecting or maintaining barbed wire or razor wire except under two narrow exceptions. The first exception allows "no more than 3 strands of barbed wire or 1 coil of razor wire" when the wire sits "a minimum of 6 feet and 2 inches above the ground" and is "placed at the top of an otherwise lawful fence enclosing a municipal, institutional, commercial or industrial building, structure or property", meaning ordinary residential yards cannot use barbed or razor wire under this exception.
" Where wire is permitted, § 8-6-3(I)(3)(c) further requires it to "extend up from the top of the fence either parallel to the fence alignment or towards the interior of the enclosed space, and not outwards beyond the property or enclosed space," so it cannot overhang a sidewalk, alley or neighboring lot. These fence-material rules sit inside the same Article I "Public Nuisances Prohibited" list as Mesa's blight, weed and vehicle-storage nuisances, so a violation is enforced through the Chapter's standard civil citation process.
Violations & Fines
A fence violation under § 8-6-3(I) is a civil nuisance citation under § 8-6-8: $250–$1,500 for a first finding under § 8-6-9(A), $350–$2,500 for a second finding within 36 months, and $500–$2,500 for a third, with each day the noncompliant fence remains a separate offense.
