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

Building setbacks (required yards) in unincorporated Glenn County are governed by the Title 15 Unified Development Code, with minimums that vary by zoning district. For residential zoning, the Glenn County minimum yard requirements provide a minimum front yard of thirty feet, minimum interior side yards of fifteen feet, and on corner lots the side yard that is not used as a front yard must be not less than fifteen feet in width; the rear yard requirement for residential development is on the order of twenty-five feet. In the AE (Exclusive Agriculture) zone, county planning approvals apply a minimum 30-foot front yard setback, a minimum 25-foot side yard setback, and a minimum 25-foot rear yard setback. These figures come from Title 15 (Chapter 15.330 and related yard provisions) and the county's published minimum-yard-requirements guidance. Because Glenn County contains many zoning districts, including rural residential estate, multiple residential, commercial, industrial, and recreation/planned districts, the exact required front, side, and rear yards depend on the parcel's specific zone, frontage, and whether it is an interior or corner lot. Setbacks are measured from property lines (and in some districts from the centerline of the abutting roadway, whichever yields the greater distance). Always verify the controlling yard requirements for your parcel and zone with Glenn County Planning & Community Development Services before siting any structure.
