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

Table 17.14.070 sets the minimum yard setback for each of Orange's sixteen residential districts. Single-family zones R1-6 through R1-R require a 20-foot front setback, a 5-foot interior side yard, and a 20-foot rear yard. R1-5 lots use a 15-foot front setback for the dwelling itself but a 20-foot setback for an attached garage, per footnote (v.2). Multi-family R2-6, R2-7, and R2-8 districts require a 15-foot front yard, 5-foot side yard, and 10-foot rear yard. The R-3 district uses the same 15-5-10 pattern, and R-4 reduces the front setback to 10 feet while keeping the 5-foot side and 10-foot rear yards.

Section 17.14.090 governs how these numbers are applied. The front yard is measured from the ultimate right-of-way line set by the Master Plan of Arterial Streets, not the existing curb, so a lot on a street slated for widening loses additional depth. Side yard setbacks run from the side property line, or from the ultimate right-of-way line on a corner lot. Rear yards are measured from the rear property line, though in R-1 districts a single-story structure may extend to within 10 feet of that line, a two-story addition may reach the same 10-foot line only where the yard abuts a street, alley, or permanent open space, and unenclosed covered patios may project to that same 10-foot mark. Corner and reverse corner lots must keep a 10-foot street side yard regardless of the base standard, and any garage opening onto a street needs a 20-foot setback. No more than 60% of the required front yard area may be paved.
