Temporary kitchen rental for Ontario facilities
A mobile kitchen trailer rental in Ontario puts a complete commercial cooking line beside the building that needs it, so a closed kitchen does not have to mean closed meal service. If the work spills into Chino, 5 miles from here, or into Eastvale, a kitchen rented here can be planned around both sites.
Kitchens in the fleet run from the 24ft Mobile Kitchen up to the 40ft Bulk Combo Kitchen. For a site like this one, the 40ft Bulk Kitchen, 40ft Mobile Combo Kitchen and 40ft Mobile Kitchen are the models to compare first, each with its listed equipment and electrical requirements.
Ontario by the numbers
With about 185,285 residents (2024 estimate), Ontario ranks 25th among 475 covered places in California. It covers about 50 square miles of San Bernardino County. San Bernardino County covers 20,068 square miles and has 24 places on this site, about 1,914,545 residents between them; the largest is San Bernardino. That works out to about 3,707 residents per square mile. Sacramento, the California capital, is about 380 miles away in a straight line, which matters for state-level emergency coordination.

What shapes kitchen rentals in Ontario, CA
Past emergencies and recovery needs in Ontario
Since 1965, San Bernardino County has been named in 59 FEMA declarations; wildfire (33 declarations) and flooding (13 declarations) lead the list. Chino has its own page with its county's federal declarations, which helps when a project spans both.
The most recent is Bridge Fire (fire management assistance declaration, FM-5537), declared September 11, 2024, with the incident beginning September 10, 2024. Evacuations, smoke damage and power shutoffs can close commercial kitchens and spoil refrigerated stock, while crews and displaced staff still need hot meals. The latest major disaster declaration is Severe Winter Storms, Straight-Line Winds, Flooding, Landslides, and Mudslides (DR-4699), declared April 3, 2023. By incident type, the count is wildfire 33, flooding 13, severe storms 7, earthquake 2 and freezing conditions 2. By decade: 1960s 3, 1970s 3, 1980s 5, 1990s 10, 2000s 21, 2010s 8 and 2020s 9. Earlier declarations include Line Fire (FM-5535, September 7, 2024), Severe Winter Storms, Flooding, Landslides, and Mudslides (EM-3592, March 10, 2023), Severe Winter Storms, Flooding, and Mudslides (EM-3591, January 9, 2023), Blue Ridge Fire (FM-5381, October 26, 2020) and Wildfires (DR-4569, October 16, 2020).
NOAA's Storm Events Database holds 551 county-based severe-weather event records for San Bernardino County between 2016 and 2025, led by flood events (488) and high-wind and thunderstorm events (63). NOAA's largest reported property loss there is $8 million, from a flash flood in July 2017. Flooding fouls kitchen equipment and drainage first, and a kitchen cannot reopen until it has been cleaned and inspected.
The National Interagency Fire Center maps 5 wildfires of 1,000 acres or more that started in San Bernardino County since 2016, together covering about 161,913 acres. The largest was the York fire in 2023, at 93,078 acres. A fire that never touches a kitchen can still close it: evacuation orders, smoke and utility shutoffs come first.
FEMA declarations apply to designated areas and do not say which individual buildings were affected.
Infrastructure work around Ontario
USASpending.gov lists 100 or more federal construction contracts of $500,000 or more with work in San Bernardino County since October 2021. The Department of Defense committed $155 million to “Construction of Mcon Project P-1231 Wastewater Treatment Plant at Mcagcc, 29 Palms California” in San Bernardino County, awarded May 2023 (award record). Another public record is “P-924, Range Simulation Training & Operations Facility,” a $87 million Department of Defense contract from August 2023 in San Bernardino County (award record). In February 2023, the Department of Defense awarded a $47 million contract for “Sims Center - Complete” in San Bernardino County, with work running to May 2026 (award record). USASpending.gov shows a $32 million Department of Transportation contract, “The Contractor Shall Provide All Program Support,” starting April 2025 in San Bernardino County (award record). A contract of that size means a crew that eats on site: hot food for many people on odd shifts, with water and wastewater to plan for the kitchen. A project in Eastvale, about 70,751 residents, would face the same phasing questions about gates, haul roads and pad space.
Renovation projects that close kitchens in Ontario
No federal contract for repairing or modernizing a building is on record for San Bernardino County. The nearest is in Orange County, about 122 miles away. The Department of Defense committed $14 million to “Design Build Building 515 Renovation” in Orange County, awarded September 2021 (award record). Another public record is “Rrch Elevator Modernization, Ronald Reagan FB and CH, Santa Ana, CA,” a $13 million General Services Administration contract from June 2023 in Orange County (award record). Work inside an occupied facility tends to take its kitchen offline for weeks, so the plan for meals has to exist before the work starts. Montclair is on the same footing: the old kitchen closes on a date, and the temporary one has to be cooking before it.
Emergency access and staging near Ontario
In California, the California Governor's Office of Emergency Services (Cal OES) works with counties on emergency operations. Official staging areas and the roads that connect them to local emergency-management hubs are published by those agencies and should be checked there. For work in Upland, look to the agencies covering that area rather than assuming the same routes.
By CMS's hospital list, the closest to Ontario is Canyon Ridge Hospital, in Chino, about 5 miles from Ontario in a straight line.
What a kitchen rental costs in Ontario
There is no single price for every job in Ontario. Equipment, rental term, delivery and site conditions all change it. As a guide, prices start at the 40ft Bulk Kitchen from $10,995, the 40ft Mobile Kitchen from $9,995 and the 38ft Mobile Kitchen from $7,995, and they may vary. Rancho Cucamonga is quoted on the same factors, but at 7 miles away a different address can change delivery and setup terms.
Starting prices are guides, and prices may vary with location, rental length, delivery, setup and utilities. A written quote states the equipment, the rental period and what is included.

Dishwashing and emergency refrigeration in Ontario
Warewashing is easy to overlook until the dish room is the thing that is down. Dishwashing trailers like the 38ft Low-Temp Conveyor Dishwashing Trailer and the 22 to 26ft Low-Temp Dishwashing Trailer can be rented with a kitchen or on their own for Ontario sites. Warewashing needs the same hot water and drain plan in Upland, 6 miles from here, as it does here.
Emergency refrigeration for Ontario means cold storage that arrives as a trailer. The 20ft MT Refrigerated Trailer is one of three 20ft temperature configurations, subject to availability for your location. A call about emergency refrigeration from Rancho Cucamonga starts with the same three questions: what failed, what is inside and where the trailer can sit.
A typical January night in San Bernardino County drops to 39°F, a typical July afternoon reaches 101°F, and the county gets about 7 inches of precipitation in a year (NOAA, 1991 to 2020). January lows run about 3 degrees warmer than the average California county. Summer heat is the stress test for cold storage here: a walk-in that struggles in July is the usual reason for an emergency call.
