Full Breakdown
Yuba County Code § 11.06.030 sets maximum lot coverage for the county's three Rural Community District zones, which apply only in unincorporated Yuba County (Marysville and Wheatland set their own limits). Residential Estate parcels under one acre may cover up to 40% of the lot with structures; RE parcels an acre or larger drop to 25%. Rural Residential parcels are capped at 15%. Rural Commercial carries no numeric coverage limit ('N/A'). Section 11.03.100 defines lot coverage as the ratio of total building footprint, including garages, carports, and roofed porches, to net lot area, excluding uncovered decks, eaves under three feet, and swimming pools.
Violations & Fines
Building permits are denied for plans exceeding the coverage cap; existing over-coverage triggers Planning Department code enforcement and may require a variance or lot-line adjustment to resolve.
