Full Breakdown
Solano County regulates fence height through its Zoning Regulations (Chapter 28 of the County Code). 3 provides that no fence shall be erected, moved, or altered, and no hedge grown, so that the portions behind the building line of the dwelling exceed seven feet in height, and the portions between the building line and any street line exceed three feet in height. A fence between the building line and any street line may exceed three feet only if the portion exceeding three feet is open so that it permits adequate visibility.
These limits apply only to the unincorporated county; each incorporated city (Vallejo, Fairfield, Vacaville, Suisun City, Benicia, Dixon, Rio Vista) sets its own fence heights within city limits. Separately, Solano County's Building & Safety Services exempts fences not over 6 feet high from a building permit, so a 7-foot fence behind the building line is permitted by zoning but may require a building permit. Agricultural and other non-residential zones are governed by the development standards for that district rather than the 7-foot/3-foot R-district rule.
Violations & Fines
Erecting a fence taller than the limits in Section 28.93.A.3, or a street-facing fence over three feet that is not open for visibility, is a zoning violation enforced by Solano County Code Compliance. Enforcement typically begins with a notice of violation and may escalate to administrative citations and required removal or modification of the non-compliant fence.
