San Bernardino County
Rialto Municipal Code §10.28.291 prohibits storing trucks, delivery vans, tractors, or other commercial vehicles used primarily for business in a residential zone if they have a one-ton or greater carrying capacity or a Gross Vehicle Weight (GVW) over 10,000 pounds. This is stricter than the statewide floor in California Vehicle Code §22507.5, which lets cities ban on-street parking of 10,000+ lb GVWR commercial vehicles in residential districts. Because Rialto is a major I-10/I-210 freight and logistics hub, the city also designates official truck routes under Chapter 10.41 RMC, and the City Engineer can revoke any non-conforming route or terminal under §10.41.060 RMC. SCAQMD Rule 2305 (Warehouse ISR) adds regional limits on idling and diesel activity at warehouses.

Ontario FAQ
Can I park my work pickup at home?
Yes, light-duty pickups under 10,000 pounds and 22 feet are generally allowed on residential streets and driveways.
Where can truck drivers stage their rig?
Semi-trucks must stage in zoned truck terminals or industrial parcels; residential storage is prohibited.
Rialto FAQ
Can I park my work box truck at my Rialto house overnight?
Not if it has a one-ton-or-greater carrying capacity or a GVW above 10,000 pounds. §10.28.291 RMC prohibits storing such commercial vehicles in residential zones, and CVC §22507.5 lets the city extend that to on-street parking in residential districts.
Where can semi tractors and large trucks legally drive in Rialto?
On streets designated as truck routes under Chapter 10.41 RMC. The 2022 Citywide Truck Route Study updated those designations. Vehicles over the 5-ton weight limit must stay on truck routes except for the shortest reasonable path to an off-route origin or destination.
What if I'm just making a delivery in a residential area?
California Vehicle Code §22507.5 specifically exempts commercial vehicles actively making pickups or deliveries of goods, and vehicles delivering materials to a job site under a valid building permit. The exemption does not cover storage between jobs.
Does SCAQMD Rule 2305 affect a small business?
Rule 2305 (Warehouse ISR) primarily applies to warehouse operators with buildings of 100,000 square feet or more — not to individual truck owners. It drives how Rialto warehouses manage diesel trucks at their gates and yards.
