Summary
Unincorporated Placer County limits residential and agricultural parcels to storing just one commercial vehicle, and even that one requires a minor use permit and a minimum lot size in most zones. County Code Section 17.56.250(B)(1) sets a zone-by-zone table of vehicle caps, permit levels and minimum lot area for RS, RM, RA, F, AE and RF districts.
Commercial Vehicle Storage. This subsection applies to the accessory storage and incidental parking of vehicles and/or self-propelled equipment used for shipping, delivery of freight and products, taxis or limousines, or other commercial or industrial purposes. 1. Residential and Agricultural Zones. Within a residential or agricultural zone, commercial vehicles shall not be stored or parked longer than necessary for the pickup or delivery of materials, goods, etc. at the site, except that one commercial vehicle may be stored or parked within a residential zone that satisfies the following requirements: Zone District Maximum Number of Vehicles Land Use Permit Minimum Lot Area Off-Street Parking Required RS, RM 1 MUP 10,000 sq. ft. or more 1 garage space per vehicle None 4.6 acres or more 1 space per vehicle
Full Breakdown
250(B) covers accessory storage and incidental parking of vehicles or self-propelled equipment used for shipping, freight delivery, taxis, limousines, or other commercial or industrial purposes. In a residential or agricultural zone, subsection (B)(1) bars commercial vehicles from being stored or parked longer than necessary for pickup or delivery, except that one commercial vehicle is allowed under a table keyed to zone district. 6 acres or more, no permit is required but one off-street space per vehicle still applies. 6 acres or larger. 3 acres. Storage tied to legitimate on-site agricultural or timber harvesting operations, as determined by the planning director, may occur in any zone district with only a zoning clearance rather than these MUP or lot-size thresholds.
A separate table in subsection (B)(2) governs commercial and industrial zones, ranging from a one-vehicle, no-permit allowance on a 6,000-square-foot C1 lot up to no numeric limit at all in the C3 and IN zones. Storing commercial vehicles as a principal use, rather than accessory to another use, is instead regulated as 'vehicle storage' under the zone district tables.
Violations & Fines
Exceeding the one-vehicle residential/agricultural cap, or storing a commercial vehicle without the required minor use permit or minimum lot area, is a zoning violation. Because Section 17.56.250 sets no specific penalty, the county's general penalty at Section 1.24.010 applies: a fine up to $1,000 per occurrence or up to six months in jail (or both), plus a civil penalty of up to $500 per day capped at $100,000 per violation, pursued by Placer County code enforcement.
