Jurisdiction and research scope
City of Ontario, California only. Full official 2026 S 32 sections and signed adopted Ordinance 3261 reviewed October 21, 2026. The current permit page retains an older dimensional definition; the enacted 2023 amendment/current code governs. Full private home placement and ordinary guest utility routes remain unresolved.

Ontario RV parking at a glance
| Location or use | What to check |
|---|---|
| Driveway storage | Paving alone does not establish a complete RV home-storage route. |
| Yard storage | Lawn/landscape/unpaved front or street-side parking/access prohibited, subject to narrow stated exceptions. |
| Street parking | Displayed permit required for listed RV/trailer/boat classes; ordinary≤ 48 h, approved houseguest≤ 72 h. |
| Loading | At most two vehicle permits/calendar month; nonconsecutive periods and 48 h issuance separation. |
| Guest sleeping | Street permits do not allow accommodation; closed private home occupied use needs separate verification. |
Do small trailers or campervans escape the permit rule?
The current code uses more than 25 ft length, 8.5 ft width or 7 ft height, but also expressly includes listed buses, trailers, boats, RVs and other classes regardless of size. The official permit page still repeats old 20 ft/80 in/78 in/6000 lb wording. Signed adopted 3261 and the current section supply the amended definition.
Who must obtain and display the permit?
A resident of the immediately adjacent property must obtain the temporary permit for their vehicle or household guest. Display it on the dashboard or windshield. Actual permit dates, safety approval, clear driveways and all other curb rules still apply.
How do 48 h, 72 h and two-per-month limits differ?
An ordinary permit may not exceed 48 h. The City may at its discretion issue a houseguest permit up to 72 h. No more than two permits may issue for a specific vehicle in a calendar month; periods cannot be consecutive, and at least 48 h must separate issuances for a specific property or vehicle.
Is there an emergency repair exception?
Sudden unexpected repairs occurring during transport have a less-than 8 h exception to the oversized permit prohibition. Commercial, public safety and government vehicles have separate routes. This does not turn routine preseason maintenance into an emergency.
Can I store the RV on gravel or the front lawn?
§4-13.03 restricts lawn, landscaping and other unpaved surfaces in residential front and street-side yards. It also restricts vehicle access through such areas. An infrequent-access exception needs Planning Director approval; new paving also requires City approval and does not create broader storage rights.
Can a short repair or wash use an unpaved area?
The section preserves a narrow washing, emergency repair or on-site construction exception for no more than 3 h total in any consecutive 24 h period. It is not a 3 h everyday storage allowance, and all other work/site requirements still apply.
May I sleep in the permitted vehicle?
The street permit conditions prohibit overnight camping, lodging, residing and other accommodation. §5-23.05 separately restricts vehicle habitation on public/private streets, lots and property held open for public use. Its 30-minute 11 p.m.–5 a.m. evidence presumption is not a free sleeping window; closed private home use needs separate zoning/camping review.
