Upland, CA Building Setbacks & Zoning: Setback Rules (2026)

The City of Upland establishes structure setbacks by zoning district in Development Code Chapter 17.04 (Residential Zones), Section 17.04.030(B) and Table 17.04-3 (Setback and Height Standards for Residential Zones). Setbacks are measured as the distance between the property line and the nearest point of the structure along a line at a right angle to the property line. Front-yard setbacks vary by zone: RS-20 requires 40 ft, RS-15 requires 30 ft, RS-10 / RS-7.5 / RS-MH require 25 ft, RS-4 requires 20 ft, and multifamily RM-10 through RM-40 require 20 ft. Interior side-yard setbacks are 10 ft in the larger-lot RS-20 and RS-15 zones and 5 ft in RS-10, RS-7.5, RS-4, RS-MH, and the RM zones. Rear-yard setbacks are generally 20 ft in the single-family RS zones (with 5 ft in the RS-MH mobile-home zone) and 15 ft in the RM multifamily zones. Residential buildings must also be separated by at least 15 feet, increased 5 feet for each story above three. These figures are City of Upland zoning requirements, distinct from the California Building Code (which governs construction, fire separation, and permits) and from Civil Code 841 (which only addresses fence cost-sharing). Because corner lots, flag lots, and projections (eaves, chimneys) have special rules, confirm the exact setback for your parcel and zone with the Planning Division at (909) 931-4130.
