Upland, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Maximum building height in Upland's residential zones is set by Development Code Chapter 17.04, Section 17.04.030(B), and Table 17.04-3 (Setback and Height Standards for Residential Zones). In the single-family RS zones (RS-20, RS-15, RS-10, RS-7.5, RS-4), the maximum structure height is 35 feet. The RS-MH mobile-home subdivision zone is limited to 16 feet. In the multifamily zones, RM-10, RM-20, and RM-30 allow up to 40 feet, and RM-40 allows up to 50 feet, with heights greater than the base limit subject to consideration through a Conditional Use Permit (CUP). The code also requires residential buildings to be separated by at least 15 feet, increased by 5 feet for every story exceeding three. These zoning height caps are City of Upland standards and are separate from the California Building Code, which governs structural and fire-safety construction but not the zoning envelope. Because height is measured per the City's definitions and accessory structures, rooftop equipment, and architectural projections may be treated differently, applicants should verify the maximum for their specific zone and any height exceptions with the Planning Division at (909) 931-4130. A taller project in an RM zone typically requires the CUP process and public hearing before exceeding the base height.
