What to know before renting in Ontario
Topics in order: past emergencies and construction where we can cite them, then renovation, emergency access, and costs. Sourced facts are listed under sources.
Renovations in Ontario
For a renovation in Ontario, the trailer needs to cover the whole closure, including punch-list and inspection time, so a monthly lease is often simpler than stacking weekly rentals. Where patients, students, or the public use the unit, include an accessible stall; an ADA combo puts it in the same trailer. Ask the building department early if the trailer will sit in a fire lane or parking area. Planning a job next door? Neighboring Upland has its own page with local notes.
Staging and access for Ontario sites
Emergency requests in Ontario usually come through the county or city emergency manager; name that contact on the quote. A staging spot that a tractor-trailer can enter and leave forward saves time; parking lots and school bus loops usually work. If Ontario roads are closed, sites in neighboring Montclair or Chino can serve as backup staging, subject to the owner's permission.
What an Ontario rental costs
Starting rates in Ontario match every other location: combos starting from $2,495 / month, or $2,995 for a 1-week rental. Ontario has more than 50,000 people, so delivery is quoted from within the city for your exact address. Water tanks, a generator, or waste hauling are added only if the site lacks hookups. See the full rental price list; rates are the same in Upland.

Before delivery
Site checklist for Ontario
Electrical
Each unit needs shore power or a generator sized for its water heaters. We check the service against the unit you pick before delivery so the first shift gets hot water.
Water and drains
Let us know if the Ontario site has a potable water tap and a sewer or septic tie-in. If it has neither, we price fresh-water tanks and waste pump-outs alongside the trailer.
Permits and placement
Some municipalities and venues ask for placement approval or a fire-lane check. Ask your local office early; we supply unit dimensions and specifications for any review.

What is the shortest rental?
One week. Longer jobs move to a monthly lease. Starting rates for both are on our rental prices page.
Do you rent ADA combo trailers?
Yes. Our ADA combo trailers add an accessible shower and restroom stall beside 3 or 8 standard stalls. Mention it in your request and we include it in the quote.
How fast is a trailer ready once it arrives?
Once the trailer is on site and utilities are ready, most shower and restroom units take about an hour. Stairs add 5 to 15 minutes; an ADA ramp takes 4 to 6 hours.
