Lot Coverage Limits: Anza vs Murrieta

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.

Lot coverage in Murrieta residential zones is generally capped at 40 to 50 percent of the lot area for primary structures, with additional floor area ratio controls in some districts.
