Vacaville, CA Fence Regulations: Height Limits (2026)

VMC 14.09.200 sets fence, wall, and dense-hedge height limits citywide. In residential zoning districts (RE, RL, RM, RH under VMC 14.09.060) the rule is: 6 feet maximum outside required setbacks or along interior property lines, and 3 feet maximum within 5 feet of the back of sidewalk or a property line - this 3-foot limit functions as a front-yard cap and a corner-visibility safeguard. In nonresidential districts (commercial under VMC 14.09.070, employment under VMC 14.09.080), fences in the required front yard along a public street are limited to 3 feet, fences outside the front yard but visible from the street are capped at 6 feet, and fences on or near interior or rear property lines are capped at 8 feet. Street-side corner setbacks in nonresidential districts revert to 6 feet. Decorative posts, caps, and ornamental features may exceed the limit so long as the over-height portion does not exceed 10 percent of the fence length. Sound-attenuation walls (typically required along Interstate 80, Interstate 505, and the Union Pacific main line) may exceed the standard limits where approved through the project entitlement. Pool barriers required by California Building Code Chapter 31 also override the 3-foot front-yard rule where necessary.
