Napa County RV parking at a glance
| Location or use | What to check |
|---|---|
| Driveway / yard | Unoccupied storage requires parcel-specific placement confirmation. Confirm setbacks, access and applicable district standards. |
| Street / loading | These private-property provisions do not establish public-street parking permission. Loading is not an exemption from separate street, access or occupancy restrictions. |
| Sleeping / utilities | Ordinary living outside mobile-home-park zoning is prohibited; an issued construction watchmen permit is separate. Parking alone does not authorize utility connections. |
The disaster allowance has ended
The county’s trailer-compliance guidance says the Glass Fire temporary housing allowance expired October 1, 2025. Its notice says RV or trailer residence on property not zoned for mobile-home parks is prohibited under Section 1.20.022(I). Do not rely on an old disaster permit or an archived policy without a current county decision.
Construction watchmen permits
An active building permit may make a property eligible for a Watchmen’s Trailer Permit during construction. Eligibility is not issuance. Ask Code Compliance and Building to confirm the approved occupant, vehicle, duration, location and required utility inspections before using a trailer as quarters.
Paved placement and unoccupied storage
The same FAQ says cars, boats and RVs must use paved, approved areas or designated parking zones rather than unpaved areas or vacant lots. This is not approval for every paved driveway: confirm the site’s actual zoning and parking designation. Temporary loading, street parking, guest use and hookups remain separate questions.
Who to contact for your setup
Ask Napa County Planning or Code Enforcement to confirm jurisdiction, the actual parcel or road, vehicle classification, position, duration and intended use. Obtain the required road, building, electrical, plumbing or wastewater approvals before relying on a parking exception. Easements, HOA rules and leases remain separate. Start with the official rule or permit guidance.
Use the Napa County parking checker to organize the starting conditions. The checker cannot approve a parcel, a variance or an unverified exception.
