Delivering to Ontario from Claremont
Ontario is about 20 minutes from our Claremont warehouse, straight down the 10, which means early setup and no rushed deliveries. We handle backyard birthdays in Creekside and Ontario Ranch, HOA block parties, school events, and community gatherings at Cucamonga-Guasti Regional Park — with bounce houses from $200 and water slides, combos and obstacle courses from $300.
Most Ontario backyards fit a standard bounce house comfortably — you need about 15 x 15 feet of flat ground, clear of trees and fences, and a standard outlet within reach. If there's no power on site, we bring a generator. More details are in our FAQs, or check your date to see what's available.
We also deliver to neighbouring Rancho Cucamonga, Chino, Montclair and Upland.
Ontario Schools, Parks & Backyard Parties
Different Ontario events need different setups. A backyard birthday in Creekside usually means one bounce house or a combo on flat grass. A school festival at Ontario High School or a fundraiser needs higher-capacity units and a certificate of insurance — we can send one ahead of the date.
For city parks like Cucamonga-Guasti Regional Park or De Anza Park, check whether a permit and a power source are required before booking; most park setups need a generator, which we bring. Company picnics and HOA block parties tend to run longer, so an obstacle course or the mechanical bull keeps older kids and adults occupied alongside the inflatables.

Which Inflatable Fits Your Ontario Party?
Guest count and yard size usually decide it. For six to ten younger kids, a single bounce house at $200 is plenty. Bigger groups or a wider age range do better with a combo — bounce area plus a slide — so kids aren't queuing for one thing.
Ontario summers run hot well into September, so water slides stay popular longer here than you'd expect. For school carnivals, church festivals and HOA events where you need to keep older kids moving, an obstacle course or the mechanical bull does more work than a second bounce house.
Everything is $200, $300 or $500 flat with delivery, setup and pickup included. Check what's available on your date.
Booking a Bounce House in Ontario
Weekends book out first in Ontario, especially April through September and around graduation. If you have a date, put it on hold early — you can check availability online in under a minute.
Our bounce houses run $200 flat, delivered, set up, anchored and picked up. Themed units — Minnie Mouse, Spider-Man, Fortnite: cost the same as a plain castle, so pick whichever your kid actually wants. Setup takes about 20 minutes and doesn't come out of your rental time.
Not sure it'll fit? Call (909) 248-8441 and describe your yard, we'd rather tell you it won't work than show up and find out.
Water Slide Rentals in Ontario, CA
Water slide rentals run $300 flat in Ontario, delivered, set up and picked up. Ontario stays hot well past Labor Day, so slides book steadily from April through late September — longer than most people plan for.
You'll need a garden hose that reaches the setup spot and somewhere for water to drain. Most Ontario backyards handle this fine; slides go on grass, and we'll position it so runoff goes where you want it rather than into a neighbour's yard. Bring towels and expect the whole area to get wet.
If a wet setup won't work at your venue, a combo with a dry slide gives you the same climb-and-slide without the water, also at $300. Check your date or call (909) 248-8441.
Mechanical Bull Rental in Ontario, CA
The mechanical bull is $500 flat in Ontario, delivered and set up. Speed is adjustable, so it runs gentle for a seven-year-old's birthday and genuinely difficult for adults at a corporate event — same unit, different settings.
It comes with an inflatable crash pad around the base, which is what makes it work for mixed age groups. Plan for about 20 x 20 ft of flat space and an operator standing by throughout — this one doesn't get left unattended like an inflatable does.
It's the most-requested add-on for school fundraisers, church festivals and company picnics around Ontario, where it draws a crowd and a queue in a way a bounce house won't. Check availability or call (909) 248-8441 — we only have one, so it books out early.

Obstacle Course Rentals in Ontario, CA
Obstacle course rentals are $300 flat in Ontario, delivered, set up and picked up. They're the unit that keeps older kids occupied — the group a standard bounce house loses interest fast.
Two riders race side by side through climbs, crawl-throughs and a slide at the end, which is what makes them work for school field days, church festivals and HOA events where you need something with a bit of competition in it. They take more room than a bounce house, so you'll want a long stretch of flat ground rather than a square yard — measure before you book and we can tell you if it fits.
Running a bigger event? Pairing an obstacle course with a bounce house for the younger kids keeps both age groups moving. Check your date or call (909) 248-8441.
Events We Deliver To in Ontario
Birthdays and backyard parties. The bulk of what we do. Usually one bounce house or a combo, set up on grass in the morning and gone by evening. Graduation season in May and June books out fastest.
Schools, churches and HOAs. Field days, carnivals, fundraisers and block parties. These usually need a certificate of insurance — ask when you book and we'll send it ahead. An obstacle course handles larger, older groups better than more bounce houses.
Corporate and community events. Company picnics, city festivals, grand openings and tailgates. The mechanical bull is the usual pick here — it draws adults as well as kids, which most inflatables don't. Check your date or call (909) 248-8441.

Ontario Bounce House Rental FAQs
How long can I keep the inflatable rentals in Ontario, CA?
Most Ontario rentals run the full day, with overnight options for parties that run late.
Party Jumpers delivers and sets up before your rental window starts, so setup time doesn't come out of your day. If your event runs into the evening, ask about an overnight hold when you check your date.
Do you charge delivery fees in Ontario?
No — delivery, setup and pickup are included for Ontario at no extra charge.
Party Jumpers delivers to Ontario from Claremont, about 20 minutes away, so the flat rate you see is what you pay. We also cover Rancho Cucamonga, Chino, Montclair and Upland. Events outside the regular service area may carry a small travel fee based on distance.
How much space do I need for a bounce house rental?
About 15 x 15 feet of flat ground, clear of trees, fences and overhead wires.
Grass is ideal for a bounce house. An obstacle course needs a long stretch rather than a square area, and the mechanical bull needs roughly 20 x 20 ft with its crash pad. Not sure your Ontario yard works? Call (909) 248-8441 and describe it — we'd rather tell you up front.
Do I need a power outlet for the inflatables?
Yes — a standard household outlet within reach of the setup area.
Blowers run continuously for the whole rental, so the unit stays inflated from setup to pickup. If there's no power at your Ontario park or venue, Party Jumpers brings a generator — mention it when you book so we load one.
What safety rules should guests follow while using inflatables?
No shoes, no food or drinks inside, and an adult supervising at all times.
Keep rider numbers appropriate to the unit size and avoid mixing toddlers with much older kids in the same session. Party Jumpers anchors every inflatable before guests arrive and cleans and sanitizes each unit between rentals.
Do you need a certificate of insurance for schools and city parks?
Usually yes — get in touch with the office and we’ll sort out what your venue needs.
Ontario schools, churches and city parks often ask for a certificate of insurance before an inflatable can be set up, and some have their own permit process on top of that. Requirements vary by venue, so get in touch with the office or call (909) 248-8441 with your venue details and we’ll tell you exactly what’s needed.
