Plumas County sets maximum building (lot) coverage by zoning district in Title 9. In the Suburban Zone, maximum building coverage may not exceed 50 percent of the lot area, with a special rule for parcels at least one acre. Other zones state their own coverage limits, so check your parcel's zone.
Maximum lot coverage in unincorporated Plumas County is governed by each zoning district's standards in Title 9, Chapter 2 - there is no single county-wide coverage percentage. In the Suburban Zone, the maximum building coverage shall not exceed 50 percent of the lot area; on a parcel at least one acre in size, the code addresses how each dwelling unit and its accessory buildings are limited (no more than one acre of coverage). Other residential, rural, agricultural, and commercial zones state their own coverage and intensity standards within their respective articles, and these work together with the zone's required yards (setbacks) and building height to control how much of a lot can be built upon. Because coverage limits interact with minimum lot size and the required front, side, and rear yards, the buildable footprint on a given parcel often depends on the combination of all these standards rather than the coverage percentage alone. To determine the maximum coverage for a specific property, identify its zoning district and review that zone's coverage provisions in Title 9, or contact the Plumas County Planning Department, which can confirm the percentage and how it is calculated for your lot.
Exceeding the zone's maximum lot coverage violates Title 9 and is enforced by the Plumas County Planning Department through permit denial, a notice to comply, a required variance, or orders to reduce the built footprint. Coverage violations are often caught at building-permit plan review, and unpermitted over-coverage can incur after-the-fact fees and abatement.
