Solano County, CA Fence Regulations: Fence Requirements (2026)

Solano County's fence requirements in Chapter 28 go beyond a simple height cap. Under Section 28.94.I, a minimum six-foot-high, solid wall or fence must be constructed - pursuant to a design approved by the Zoning Administrator - to separate parking and other commercial, industrial, and nonresidential uses that abut residential districts or residences. This is a buffering/screening requirement, not a general residential fence mandate. Residential fences themselves are governed by the height and visibility limits in Section 28.93.A.3 (7 feet behind the building line, 3 feet street-facing unless open for visibility). Fences must also respect corner-lot visibility, and architectural features such as cornices and eaves may project into required yards up to two and one-half feet, while unenclosed porches or stairways may extend up to six feet into a front or rear yard and three feet into a side yard. Most residential boundary fences do not require a building permit if 6 feet or less. Whether a particular fence is required, optional, or restricted depends on the property's zoning district, so owners should verify their zone before building.
