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

Building setbacks in unincorporated Stanislaus County are established per zoning district in the Title 21 Zoning Ordinance, so the required distance depends on your parcel's zone and the classifying street. For the Single-Family Residential (R-1) district, Section 21.28.070 sets the front yard at not less than 70 feet from the existing centerline of the street (nor less than 15 feet from the planned street line) on a major street or expressway; not less than 45 feet from centerline on a 60-foot collector street; and not less than 40 feet from centerline on a 50-foot minor street — with any vehicle opening kept at least 20 feet from the property line it faces. Interior side yards and rear yards are five feet, and on corner lots the main building and garages without direct street access may sit five feet closer to the planned street line than the front yard. The Rural Residential (R-A) district uses the same front-yard centerline distances and a five-foot side/rear standard (§21.24.080). General provisions in Section 21.08.060 allow limited encroachments: cornices, eaves, and canopies may extend up to three feet into a required yard, and uncovered porches/terraces up to three feet into a side yard and six feet into a front yard. Because measurements run from the street centerline or planned line rather than your fence, always confirm the controlling figures for your zone with the Planning Department.
