Loma Linda, California Zoning Map

The HR-C zone at 1,728.21 acres is the city's largest designation by far, and its primary purpose is to limit development in steeper terrain and protect ridgelines and natural habitat. The Low Density Hillside Preservation (HR-LD, 293.76 acres) zone allows limited residential development at estate scales. Projects on hillside parcels face grading limits, fire safety requirements under Cal Fire standards, and potentially biological resource review. Investors targeting hillside land should budget for extensive site feasibility and environmental review costs.

The I-HC zone at 462.66 acres encompasses Loma Linda University Medical Center and affiliated healthcare campuses - one of the largest academic medical systems in California. This institutional anchor generates substantial demand for medical office, professional services, housing, and hospitality uses in surrounding commercial zones. Investors targeting healthcare-adjacent commercial development, medical office buildings, or workforce housing for hospital employees should focus on C2, BP, and CO parcels within proximity to the I-HC boundary.

High Density Residential (R3, 429.74 acres) and Very High Density (R4, 25.57 acres) together provide over 455 acres of designated higher-density residential land - a substantial multifamily opportunity for a city of Loma Linda's size. Medium Density (R2, 33.03 acres) provides a mid-tier option. California's density bonus law can increase unit counts further on qualifying affordable projects, and ADU law applies citywide across R1, R2, R3, and R4 parcels.

The PC designation typically governs large master-planned areas with internally negotiated land use programs, phasing requirements, and design standards. At 334.85 acres, Loma Linda's PC zone is substantial and may encompass multiple sub-areas with different programmed uses. Developers acquiring within a PC boundary inherit the development program agreed at time of plan approval, so reviewing the specific PC agreement - including vesting conditions and infrastructure obligations - is a critical pre-acquisition step.

Loma Linda was founded by the Seventh-day Adventist Church, and that heritage shapes the city's institutional land base (the I-HC zone), its wellness-focused economy, and certain community standards that may be reflected in design review preferences and use permit conditions. While zoning itself is secular, developers should understand that the city's master plan reflects a community identity centered on health and institutional uses, which influences approval culture for projects that may conflict with that character - such as certain hospitality, entertainment, or industrial uses.
