Residential lot coverage in Moreno Valley is generally capped at 40 to 50 percent in R-5 and R-10 districts, with impervious-surface limits applying separately for stormwater compliance under the Santa Ana RWQCB permit.
Lot coverage refers to the percentage of lot area occupied by buildings (principal plus accessory structures). In R-5 single-family zones, maximum building coverage is typically 40 percent. Estate R-A / R-10 zones allow lower coverage (often 25 to 30 percent) to preserve open character. Commercial and industrial districts permit higher coverage (up to 60 to 80 percent) with landscape and parking set-asides. Impervious surface coverage — including driveways, patios, and pool decks — is regulated separately under the city's stormwater ordinance implementing the Santa Ana Regional Water Quality Control Board MS4 permit. Projects creating or replacing 5,000 sq ft or more of impervious surface typically require a Water Quality Management Plan (WQMP) with permanent BMPs such as bioretention or pervious paving. ADUs are excluded from local lot coverage limits under state law if they comply with Government Code thresholds. Setback areas must generally remain free of structures except for allowed projections.
