San Ramon, CA Fence Regulations: Material Restrictions (2026)

E lists prohibited fence materials that apply citywide, in both residential and non-residential zones, regardless of the height limits set elsewhere in the fence chapter. Barbed wire and electrified fencing are banned outright, as are razor wire and concertina wire whether attached to a fence or wall or installed on their own. Chain link fencing is barred specifically within a front yard or street side yard, though it remains allowed in a rear or interior side yard. The only way around these bans is Zoning Administrator approval, which the Section reserves for animal control needs, documented special security needs, or where a City, State, or Federal law or regulation actually requires the prohibited material.

The Section also carves out an exception for open wire fencing, such as field or ranch-style wire fencing, on property that abuts open space, recognizing that agricultural and hillside parcels bordering undeveloped land have different fencing needs than a typical residential lot. These material rules apply on top of, not instead of, the height limits in Table 3-1 and Table 3-2 and the flood-zone and lattice provisions elsewhere in Section D3-4.
