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

Maximum structure heights for unincorporated Ventura County are set in the development standards tables of the Non-Coastal Zoning Ordinance. Under Section 8106-1.1, principal structures in the OS-REC, OS, AE, RA, RE, RO, R1, and R2 zones are limited to 25 feet in height. Height may be increased above 25 feet up to a maximum of 35 feet if each side-yard setback is at least 15 feet (or as specified by permit). RHD and RPD zones allow up to 35 feet. Building height is measured under Section 8106-1.3, which addresses flat grades (vertical distance from grade to the highest point of the roof) and sloping grades separately. For commercial and industrial zones under Section 8106-1.2, CO and C1 principal structures are generally limited to 25-35 feet, M1 to about 30 feet, with heights up to a 60-foot maximum available subject to Decision-Making Authority or Planning Commission approval; structures may reach 60 feet when located within 100 feet of an R-zone subject to approval. Accessory structures are generally limited to 15 feet, but under Section 8106-7.4, an accessory structure set back 20 feet from all property lines may exceed 15 feet, though it cannot exceed the principal structure's maximum height without a discretionary permit. Height exceptions for antennas, roof structures, and airport approach areas appear in Sections 8106-7.1 through 8106-7.6.
