Stanislaus County, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Maximum building heights in unincorporated Stanislaus County are set by zoning district in the Title 21 Zoning Ordinance. In the Single-Family Residential (R-1) district, Section 21.28.040 limits dwellings to a maximum of 35 feet and detached accessory buildings to a maximum of 20 feet. The Rural Residential (R-A) district, under Section 21.24.040, caps all buildings at 35 feet. The same sections also contain the fence height rules (eight feet side/rear, three feet front and corner-side yard), reflecting that the County treats building and fence heights together within each district chapter. Title 21's general provisions in Section 21.08.030 allow specific appurtenances — chimneys, elevators, communication towers, mechanical equipment, monuments, spires, campaniles, and public or quasi-public buildings — to exceed the district height limits, but only after obtaining a use permit in each case. Flagpoles have no height limit, and conventional television antennas up to 60 feet are permitted in all districts. Section 21.08.030 also cross-references Title 17 of the County Code for additional height-related provisions. Because each zoning district sets its own maximum, and because higher-intensity zones differ from residential ones, verify the height limit for your specific parcel's zone with the Planning Department before designing a tall structure.
