What should developers know about Upland zoning?
Upland is a Inland Empire city in San Bernardino County with a 40-district zoning map that reflects both its historic foothills character and its position within the broader Los Angeles-to-Riverside development corridor. The residential core is dominated by large-lot single-family zones: Residential Single Family Low (RS-10) at 1,677 acres and RS-7.5 at 1,441 acres are the two largest residential districts, with RS-15 (768 acres) and RS-20 (608 acres) extending into more spacious lot configurations near the mountain base. The Mining (M) zone at 732 acres reflects active aggregate and sand-and-gravel extraction from the alluvial fan of the San Gabriel Mountains - a land use constraint unique to Upland's geology.
Commercial activity is structured around a range of mixed-use designations rather than traditional strip commercial zones: Commercial Residential Mixed Use (C/R-MU, 200 acres), Business Residential Mixed Use (B/R-MU, 122 acres), Commercial Industrial Mixed Use (C/I-MU, 261 acres), and Commercial Office Mixed Use (C/O-MU, 121 acres) together cover nearly 700 acres of mixed-use land. Highway Commercial (HC, 105 acres) and Regional Commercial (RC, 75 acres) handle more conventional auto-oriented retail. Cable Airport (CA, 114 acres) is a distinct zone protecting the public-use airport in the city's eastern area.
Multifamily capacity is structured through tiered Residential Multifamily zones: RM-10 (132 acres, up to 10 units per acre), RM-20 (413 acres, 10-20 units per acre), and RM-30 (46 acres, 20-30 units per acre). The Specific Plan for The Colonies (SP-1, 401 acres) governs the city's major master-planned mixed-use development. Building controls cover FAR, lot, density, coverage, pervious, setbacks, and height. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
Upland zoning: frequently asked questions
What multifamily residential zones does Upland offer and how are they differentiated?
Upland structures multifamily zoning in three explicit density tiers: RM-10 allows up to 10 units per acre (132 acres), RM-20 allows 10-20 units per acre (413 acres), and RM-30 allows 20-30 units per acre (46 acres). RM-20 is the largest multifamily district and the most common target for apartment development. California ADU law also applies to the RS-designated single-family zones, supporting infill across the city's extensive low-density residential base.
How does the Mining (M) zone affect development feasibility in parts of Upland?
The Mining (M) district at 732 acres covers active extraction areas on Upland's alluvial fan and foothills edge. Land within this zone is subject to extraction operations and associated noise, dust, and truck traffic, as well as reclamation requirements under SMARA (Surface Mining and Reclamation Act) when mining ceases. Adjacent parcels may also face compatibility constraints. Developers should assess the operational status of any nearby mining activity and reclamation status before acquiring adjacent land.
What is the Colonies Specific Plan (SP-1) and what uses does it encompass?
The Colonies (SP-1) at 401 acres is a master-planned mixed-use development in the northeastern part of Upland that integrates retail, office, residential, and institutional uses under a single site-specific regulatory framework. Development within SP-1 must comply with the specific plan rather than standard code provisions. The district is notable for its regional shopping, hotel, and commercial office component along the 210 Freeway corridor.
How does Cable Airport (CA) zoning affect nearby development?
The Cable Airport (CA) zone at 114 acres protects the active public-use general aviation airport and its approach surfaces. Properties within or adjacent to the CA zone are subject to Airport Land Use Compatibility Plan (ALUCP) review through the San Bernardino County Airport Land Use Commission, which can restrict building heights and certain sensitive land uses such as housing or schools within defined noise and safety zones.
What commercial mixed-use options exist for developers in Upland?
Upland's commercial framework is dominated by four mixed-use overlay designations: Commercial Residential Mixed Use (C/R-MU, 200 acres), Business Residential Mixed Use (B/R-MU, 122 acres), Commercial Industrial Mixed Use (C/I-MU, 261 acres), and Commercial Office Mixed Use (C/O-MU, 121 acres). This mixed-use structure offers considerable flexibility for projects combining retail, residential, office, or industrial uses on the same parcel - an important advantage for developers building mixed-income or live-work products.
