Accessory dwelling units shall be metered separately from the primary dwelling for gas, electricity, communications, water, and sewer service except for accessory dwelling units constructed entirely within existing structures pursuant to subsection I, Special Provisions for Accessory Dwelling Units Constructed Entirely Within Existing Structures.

Full Breakdown
California's Accessory Dwelling Unit law (Gov. Code §§ 66310-66342) directs cities to streamline ADU approvals, and West Sacramento's own zoning code implements that locally at Municipal Code § 17.30.040.E.1: no setback is required for an existing, legally permitted garage converted into an ADU. Any later addition that increases the encroachment into the side or rear setback, however, must still meet the standard four-foot ADU setback that applies elsewhere under § 17.30.040.E. The waiver covers the converted garage's existing footprint only, and it applies to any qualifying residential lot within the City of West Sacramento, Yolo County.
Violations & Fines
Building an addition onto a converted garage without meeting the standard setback for that new construction can draw a stop-work order and permit denial from West Sacramento's Building Division.
