Avondale, AZ Fence Regulations: Height Limits (2026)

Sec. 28-297(c) sets Avondale's baseline wall and fence heights by yard location. In a required front yard setback, including for single-family homes, the maximum is three feet six inches. The zoning administrator or authorized designee may approve a taller front-yard wall, but never above six feet, and only if the owner shows that anything over three feet six inches still preserves line-of-sight surveillance to the street through openings, transparent materials, or a varied height and material pattern. Behind the front setback, in the required side and rear yards, walls may rise to six feet, extending to eight feet where a taller wall is needed to screen a service area.

Single-family lots backing onto an arterial road get the same eight-foot allowance. Through lots whose rear line touches an arterial street have no choice in the matter: Sec. 28-297(c)(4) makes a masonry wall mandatory there, capped at eight feet. All of these limits are measured from finished grade at the wall's base, per subsection (c)(1), not from the top of a berm or slope. The height rules sit inside Sec. 28-297's broader design standards, which also require two different materials or treatments on every on-site wall, a decorative cap on masonry walls, and periodic breaks in long perimeter walls for pedestrian access. Any wall exceeding these limits is treated as noncompliant construction subject to development plan review before it can be built or extended.
