Full Breakdown
The R-A (Residential Agricultural) zone caps one-family residences at 40 feet. Other buildings or structures may reach 50 feet only with a height exception approved under § 17.172.230. No building may ever exceed 75 feet, and no other structure may exceed 105 feet, even with a variance granted under Chapter 17.196. The R-1 one-family zone and R-R rural residential zone carry the same 40-foot residential cap under their own sections. This applies only to unincorporated county land; Riverside, Temecula, Murrieta, Moreno Valley and the county's other 24 cities set their own height limits.
Violations & Fines
Plans exceeding the cap are denied at building permit review by the county's Building and Safety Department; a structure built over height without an approved exception or variance is a zoning violation subject to code enforcement correction.
