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

Section 17.10.060 (Setback Requirements and Exceptions) defines how every yard is measured: "Setbacks shall be 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," and setback areas must stay "unobstructed from the ground to the sky," subject to the California Building Code. Table 17.04-3 (Setback and Height Standards for Residential Zones), adopted under § 17.04.030, then sets the actual minimums by zone. In the RS-4 zone (4,000 sq. ft. minimum parcels, the city's smallest single-family lots), the front setback is 20 feet, the side setback is 5 feet, and the rear setback is 20 feet, with a 35-foot maximum structure height.

Front-yard minimums climb with lot size across the RS series: 25 feet in RS-7.5 and RS-10, 30 feet in RS-15, and 40 feet in RS-20, while the multi-family RM-10 through RM-40 zones use a 20-foot front and 15-foot rear setback. RS-10 carries a footnoted exception: "One side yard must be 10 feet minimum unless alley access is provided." Corner lots face additional rules: reverse corner lots must match the abutting lot's front setback on the street side, with a 15-foot minimum (§ 17.10.060(B)), and all corner lots must keep a clear vision triangle, measured 25 feet along the front and side property lines, free of structures, vehicles, or landscaping over 3 feet tall (§ 17.10.060(C)).

Limited projections, such as eaves up to 2.5 feet or open balconies up to 6 feet, are allowed into required setbacks per Table 17.10-1, but bay windows may not exceed 60% of the wall width they project from.
