Napa, CA Parking Rules: RV & Boat Parking (2026)

Napa's RV parking rules combine state vehicle law, recent local ordinance amendments, and Title 17 zoning. (1) On public streets and alleys: NMC §10.36.070, fully rewritten by Ordinance O2024 adopted December 17, 2024 (effective January 17, 2025), defines an 'oversized vehicle' as any vehicle, motorized or nonmotorized, that exceeds 20 feet in length, or 85 inches in width, or 85 inches in height (mirrors and accessories count toward the dimension). Oversized vehicles also automatically include buses (California Vehicle Code §233), trailers and semi-trailers (CVC §630), boats not connected to trailers, trailer coaches (CVC §635), and recreational vehicles (motor homes, slide-in campers, travel trailers, truck campers, camping trailers, fifth-wheel travel trailers). Such vehicles may not stop, park, or stand on any public street, alley, or right-of-way for more than 4 consecutive hours, after which they must relocate more than 1,320 feet for at least 72 hours. A 48-hour loading/unloading exemption applies when the RV is parked immediately adjacent to the property where it is DMV-registered. (2) State-law 72-hour rule: California Vehicle Code §22651(k) independently authorizes tow of any vehicle parked on a public street for 72 or more consecutive hours; NMC §10.36.090 (also rewritten by Ordinance O2024) implements this with a 1,320-foot proof-of-movement standard (100 feet for vehicles registered to that street with no driveway). (3) On private property: the Napa Zoning Ordinance (Title 17) prohibits storage of motor vehicles, motor homes, recreational vehicles, boats, airplanes, trailers, parts, and salvaged materials in any required front or side setback area of a residential property. (4) Enforcement: Napa Police Department enforces on-street violations and may tow under California Vehicle Code §§22650 et seq.; the Community Development Department / Code Enforcement enforces private-property setback storage violations under Title 17.
