Palo Alto zoning establishes front, side, and rear yard setbacks by district, with R-1 single-family lots typically requiring 20-foot front, 6 to 8-foot side, and 20-foot rear yards.
Setback requirements in Palo Alto are established in Municipal Code Title 18 Zoning and vary by district. In R-1 single-family districts, typical requirements are a 20-foot front yard, side yards of 6 feet (interior) and 10 feet (street side on corners), and a 20-foot rear yard, with some variation for smaller or larger lots. R-2 and multifamily zones have different standards, and commercial zones often have reduced or zero setbacks with design overlay requirements. Historic districts impose additional constraints to preserve neighborhood character. ADUs built under state law (Government Code 65852.2) have reduced setbacks (4 feet side and rear) that preempt local standards. Encroachments like eaves, chimneys, and bay windows have specific allowances into required yards. Fences in setback areas are governed by height limits (6 feet rear/side, 3-4 feet front typically). Nonconforming structures built before current rules are generally grandfathered.
