Avondale's Zoning Ordinance caps front-yard walls and fences at three feet six inches, with approval up to six feet if line-of-sight surveillance is kept. Rear and side yards allow up to six feet, rising to eight feet for single-family lots next to an arterial road.
Avondale regulates wall and fence heights in Chapter 28, Article 12 of its Zoning Ordinance rather than relying on state law. Under Section 28-297(c)(2), walls and fences in a required front yard have a maximum height of three feet six inches, though the City may approve up to six feet where adequate line-of-sight surveillance of the property is maintained. Section 28-297(c)(3) sets the maximum height at six feet in areas behind the front setback (rear and side yards), and allows eight feet for single-family uses when the wall is adjacent to an arterial road. Section 28-297(c)(4) similarly permits masonry walls up to eight feet on through lots whose rear lines abut an arterial street. Heights are measured from finished grade. Because these limits live in the zoning code, they apply citywide to residential lots regardless of the underlying district. Homeowners planning anything taller than the standard limits, or near a corner or intersection, should confirm the exact figure with Avondale Development Services before building, since corner-lot sight-distance rules can further restrict height near driveways and street corners.
Walls or fences exceeding the height limits in Section 28-297(c) are zoning violations enforced by Avondale Code Compliance. The City may require the owner to lower or remove the non-conforming portion. Heights above seven feet additionally require a building permit under Section 28-297(c)(5).
