Livermore Height Limits Rules (2026): What You Need to Know

The City of Livermore Development Code establishes maximum permitted heights for fences, walls, and hedges based on the zoning district and the location of the fence within the property's setback areas. These height limits are designed to balance residents' privacy needs with the city's goals of maintaining open, attractive streetscapes and ensuring public safety through adequate sight lines for drivers and pedestrians.

In all residential zoning districts — including R-1 (single-family residential), R-2 (medium-density), and R-3 (multi-family) — fences, walls, and hedges in the required front yard setback area are limited to a maximum height of 3 feet (36 inches). This low-profile standard preserves the open character of Livermore's residential streets and ensures that drivers have unobstructed sight lines when backing out of driveways or approaching intersections. The 3-foot limit applies to all fence materials including wood, vinyl, wrought iron, chain-link, and masonry.

In side yards and rear yards behind the front building line, fences and walls may reach a maximum height of 6 feet. This provides reasonable privacy for backyards and side yards while remaining within the height that can be safely constructed without engineered footings for most standard fence materials. Fence height is measured from the highest adjacent finished grade on either side of the fence. On sloped lots — which are common in Livermore's hillside neighborhoods near the ridgelines to the south and east — this measurement method can significantly affect the permitted fence height relative to the uphill and downhill sides.

When a retaining wall is combined with a fence on top, the total combined height of the retaining wall plus the fence may not exceed 8 feet, with the fence portion limited to 6 feet. Retaining walls exceeding 4 feet in exposed height require a building permit with engineered drawings regardless of whether a fence is placed on top.

Corner lots and properties at street intersections must maintain a sight-distance triangle as defined by the City Engineer. Within this triangle — typically the area within 25 feet of the intersection of the two curb lines — fences, walls, hedges, and other visual obstructions must not exceed 30 inches in height, or must be constructed of open materials (such as wrought iron or tubular steel) that do not obstruct driver sight lines. The specific dimensions of the sight-distance triangle may vary depending on street classification and speed limits.

Fences exceeding 6 feet in height require a building permit from the Community Development Department and may require Planning Commission review for consistency with the neighborhood development standards. Any fence exceeding 6 feet also requires structural engineering for wind load and seismic considerations appropriate to the eastern Alameda County region.
