Santa Clarita Zoning Intelligence

BP covers approximately 3,189 acres and is the primary employment zone in Santa Clarita, designed for office, R&D, light manufacturing, and logistics uses in a planned park setting. Santa Clarita's location along Interstate 5 and SR-14 makes it a competitive logistics market, and BP-zoned land provides the bulk of that supply. Developers should verify whether individual BP parcels have specific plan overlays, as many are governed by master development agreements that add design and infrastructure standards.

NU1 through NU5 zones allow very low densities (0.05 to 1 dwelling unit per acre) across roughly 5,351 acres of hillside and transition land. Grading constraints, wildfire risk, and infrastructure extension costs are the dominant feasibility variables in these zones - the zoning designation alone does not determine whether a parcel is buildable. Developers considering non-urban residential sites should conduct geotechnical and wildfire hazard assessments early in due diligence.

Specific Plan (SP) designations cover approximately 3,889 acres and represent master-planned communities or mixed-use areas governed by detailed specific plan documents rather than the standard zoning code. Each specific plan sets its own land use mix, development standards, phasing requirements, and infrastructure obligations. Developers working within an SP-zoned area must obtain and review the relevant specific plan document, as the standard municipal code takes a back seat to the specific plan in those areas.

Mixed Use Corridor (MX-C at 247 acres) and Mixed Use Neighborhood (MX-N at 331 acres) zones accommodate residential above commercial ground floors in transit and neighborhood contexts. Urban Residential 3 (UR3 at 11 dwelling units per acre, 2,264 acres) and UR4 (18 dwelling units per acre, 507 acres) support more conventional multifamily development. The highest-density zone, UR5 (18-30 dwelling units per acre), covers 754 acres. State ADU and density bonus laws apply throughout the city on eligible parcels.

OS at 9,101 acres is the single largest land category and effectively defines the outer edges of the developable envelope. OS-A (Open Space Agriculture at 1,217 acres), OS-BLM (Bureau of Land Management at 84 acres), and OS-NF (National Forest at 387 acres) add further conservation constraints. Together these open space categories mean that Santa Clarita's developable land is geographically concentrated in the valley floor and existing community areas - a fact that drives land values and makes infill and specific plan buildout the primary development pathways.
