Summary
Carson's 1977 zoning ordinance sets minimum yard depths for RA, RS, and RM residential lots: front and rear yards use a fixed footage or a percentage of lot depth, whichever is less, and side yards scale with lot width.
Each residential lot shall have a front yard with a required depth of twenty (20) feet or twenty (20) percent of the lot depth, whichever is less. [...] Each lot shall have a rear yard with a minimum depth of fifteen (15) feet or fifteen (15) percent of the lot depth, whichever is less, with the exception of accessory dwelling units, which shall be developed consistent with the standards in CMC § 9122.1...
Full Breakdown
Front yards must be at least 20 feet, or 20 percent of lot depth, whichever is less (CMC § 9126.23). Side yards run 3 feet to 10 percent of lot width for single-family homes and 6 feet to 20 percent for multi-family projects, doubled on a street-side lot line (§ 9126.24). Rear yards need at least 15 feet, or 15 percent of lot depth, whichever is less (§ 9126.25). ADUs and two-unit developments instead use a flat 4-foot side/rear setback under § 9122.1, since state ADU law (Gov. Code §§ 66310-66342) overrides conflicting local limits. These Part 2 standards, last amended in 2022, govern RA/RS/RM lots under Carson's still-operative 1977 zoning chapter.
Violations & Fines
Building within a required yard without an approved exception invites a stop-work order and denial of building-permit sign-off; correction typically means moving or removing the encroaching wall or structure.
