Riverside County Ordinance No. 348 (Zoning Ordinance) establishes minimum setbacks for all structures in unincorporated areas. Typical R-1 single-family zones require 20-foot front yards, 5-foot interior side yards, 10-foot street side yards, and 10-foot rear yards, though setbacks vary by zone classification (R-R rural, R-A residential-agricultural, etc.).
Under Ordinance No. 348, most residential zones in unincorporated Riverside County cap principal structures at 35 feet or 2.5 stories. Accessory structures are generally limited to 18 feet. Height is measured from finished grade to the highest point of the roof, with stricter limits near the Mt. Palomar Observatory dark-sky zone.
Riverside County Ordinance No. 348 limits the percentage of a lot that structures can cover. Typical residential coverage maximums range from 35% in R-1 zones to 50% in R-3 multi-family zones. Coverage is calculated from the footprints of all buildings, including accessory structures, but excludes paved surfaces and pools.
