Summary
Unincorporated Pinal County caps corner-lot fences at 24 inches inside the sight visibility triangle, but lets front-yard fencing run 5 to 6 feet if it is open style, pipe rail or wrought iron, with gates up to 8 feet. Side and rear fences or walls up to 6 feet are exempt from setbacks entirely.
A. Setbacks. 1. On corner lots, fences exceeding 24 inches in height are not permitted within the sight visibility triangle. 2. Other setback requirements of this title shall not apply to fences or walls being used as fences located in front yards (meaning along the front and sides of the front setback area) that are either: a. Open fencing of five feet or less in height; or b. Fencing of five feet or less in height where the portion of fence over three feet is open fencing; c. Fencing of six feet in height consisting of pipe rail or wrought iron. Gate may be no higher than eight feet. 3. The setback requirements of this title shall not apply to fences or wall type fences of six feet or less in height that are being used as fences in side and rear setbacks. 4. On office, commercial and industrial properties, the planning director may exempt fences or wall type fences higher than six feet from the setback requirements of the zone.
Full Breakdown
100 sets Pinal County's fence rules by location rather than a single flat height cap. On corner lots, any fence over 24 inches tall is barred from the sight visibility triangle, the sightline area planners protect so drivers can see cross traffic. In front yards, along the front and sides of the front setback, the county waives its normal setback requirements for three specific fence types: open fencing 5 feet or less in height, fencing 5 feet or less where everything above 3 feet is open style, or fencing up to 6 feet built of pipe rail or wrought iron (gates on that last type can run up to 8 feet).
For side and rear yards, any fence or wall-type fence of 6 feet or less is exempt from the title's setback requirements outright, so most residential perimeter fencing in Pinal County tops out at 6 feet by design even though the code does not state that number as a universal ceiling. Commercial, office and industrial parcels get more flexibility: the planning director may exempt fences or walls taller than 6 feet from zone setback requirements case by case. The same section also regulates materials and safety regardless of height: fences may use wood, metal rail, wire or chain link approved by the planning director; electrified fencing is barred except for livestock enclosures in rural zones; barbed wire is barred except in rural and industrial zones; and no fence may incorporate broken glass, tires, junk, scrap or hazardous material.
Wall-type fences may be built of concrete, stone, brick, tile or mosaic glass, but broken glass used as a deterrent on top of a wall is prohibited under the same subsection. The section derives from Ordinance No. 011812-ZO-PZ-C-007-10, § 11.
Violations & Fines
Community Development (Planning and Development Services) enforces § 2.150.100 through the county's zoning code compliance process; a fence built over the 24-inch corner sight-triangle limit or otherwise outside the setback exemptions is treated as a zoning violation subject to a correction notice and, if unresolved, the county's standard civil citation and abatement process for development code violations. Commercial or industrial property owners seeking a taller fence without triggering enforcement must get the planning director's exemption before construction, not after.
