Bounce House Rentals in Lafayette
Compare prices from Lamorinda vendors delivering to Lafayette — plus park rules at Lafayette Community Park, why the Reservoir doesn't allow inflatables, and the generator-required setup rules
Lafayette is the central Lamorinda hub — the L in Lamorinda — sitting just east of the Caldecott Tunnel along Highway 24. With ~25,500 residents and a famously park-rich, school-anchored community, Lafayette runs one of the cleaner backyard-and-park inflatable scenes in Contra Costa. The City allows bounce houses at most reservable park sites with a few specific operating rules that catch first-time renters: sandbags only (no stakes), bring your own generator (no city power), and reservations open up to a year in advance.
The flagship venue is Lafayette Community Park (68 acres on St. Mary's Road), with a reservable group picnic area that's the go-to spot for medium-to-large birthday parties and school events. Smaller neighborhood parks have first-come picnic pavilions. The exception that trips up parents: Lafayette Reservoir — operated by EBMUD, not the City — does not allow bounce houses at any of its picnic areas, even though everything else looks like a city park. If your party has a Reservoir picnic reservation, you can't add an inflatable.
Lamorinda climate is mild and dry compared to Concord and the Tri-Valley — Lafayette sits in the lee of the Berkeley Hills, with summer highs in the high 70s and low 80s, slightly cooler than inland Concord and Walnut Creek but warmer than Berkeley or Oakland. Late spring through early fall is reliable party weather; rare summer fog rarely makes it past Orinda.
With JumpFun, you can compare prices from local Lamorinda vendors delivering to Lafayette, including the same vendors that cover Moraga and Orinda — most vendors serving Lafayette also serve all three Lamorinda towns.

Lafayette Park Rules for Inflatables
Lafayette allows bounce houses at most reservable city park sites — primarily Lafayette Community Park's group picnic area. The Lafayette Reservoir (EBMUD-managed) is a separate jurisdiction that does NOT permit inflatables. The Lamorinda-wide rules: vendors must use sandbags or water barrels (no stakes anywhere), bring your own generator (Lafayette city parks don't provide power for inflatables), and provide proof of liability insurance.
Reservable group picnic area required for inflatables
Bounce houses are allowed at Lafayette's reservable group picnic site (most commonly Lafayette Community Park). They're not permitted in general park grass areas, playgrounds, or first-come-first-served pavilions. Reservations open up to one year in advance and must be booked at least 30 days before the event. Call Lafayette Parks & Recreation at (925) 284-2232.
No stakes — sandbags or water barrels only
Lafayette parks prohibit driving stakes into turf because of the irrigation system underneath. Your vendor must anchor with sandbags or water barrels, which is standard industry practice. Reputable Lamorinda vendors carry these by default; confirm before booking.
Bring your own generator (5,500W minimum)
Lafayette city parks don't supply electrical power for inflatables. You'll need a 5,500W running-watt generator on site (most vendors include one in the rental quote). Concord and the Tri-Valley provide power at some sites; Lafayette doesn't, so plan ahead.
Proof of liability insurance required from vendor
Vendors must carry general liability insurance and provide proof to Lafayette Parks & Rec ahead of the event. The City keeps insurance certificates on file for repeat vendors. Most established Lamorinda inflatable companies are already familiar with the paperwork; ask your vendor whether they've previously rented at Lafayette Community Park.
Lafayette Reservoir does NOT allow inflatables
The Lafayette Reservoir's picnic areas (50-person and 200-person sites) are operated by EBMUD, not the City of Lafayette. EBMUD prohibits bounce houses, jumpers, and similar inflatables at all Reservoir picnic sites. This is the most common surprise for Lamorinda parents — confirm you're booking at Lafayette Community Park, not the Reservoir, if you want a bounce house.
Smaller neighborhood pavilions are first-come-first-serve
Many Lafayette parks (Buckeye Fields, smaller neighborhood parks) have first-come picnic pavilions that aren't suited for reserved-equipment events. For a guaranteed inflatable setup, book the Community Park group area.
Permits & Reservations
Gathering Permit
Lafayette Community Park's group picnic reservation is the primary path. Includes use of the picnic area; the inflatable itself is permitted as long as your vendor provides insurance proof. No separate inflatable permit form.
Special Event Permit
Larger events (school field days, neighborhood block parties, 200+ guests) go through Lafayette's Special Event Permit process. Required for amplified sound or street closures. Most birthday parties don't need this.
Group Picnic Reservation
The Lafayette Community Park group picnic area is the inflatable-friendly option. Other Lafayette parks have picnic pavilions on a first-come-first-serve basis (not reservable, not suitable for guaranteed inflatable setups).
Available at: Lafayette Community Park (group picnic area — inflatables OK with reservation), Buckeye Fields (Little League primary use; not for inflatable parties), Lafayette Reservoir (EBMUD — picnic OK but inflatables NOT allowed), Smaller neighborhood pavilions (first-come, not for inflatables)

Inflatable Rental Pricing in Lafayette
Lafayette pricing runs slightly above Concord and roughly matches Tri-Valley rates (Danville, Pleasanton). Vendors that cover Lamorinda typically include the generator rental in the quote — confirm this is the case rather than assuming. If you're booking at a city park, no separate park-fee surcharge applies, but Lafayette Community Park's group picnic reservation is its own line item paid to Parks & Rec.
Standard Bounce House
$185–$285
13×13 to 15×15, full-day with delivery — fits typical Lamorinda backyard or the Community Park group picnic area
Combo Unit (Bounce + Slide)
$320–$475
Most popular pick — Lafayette's reliable summer weather drives combo demand May through September
Water Slide
$345–$575
Summer favorite. Water source needed — Lafayette Community Park's group picnic site has running water
Obstacle Course
$425–$800
40-foot courses fit Community Park's group area or a deep Lamorinda backyard
Generator (often included)
$95–$150
Required at Lafayette city parks — most Lamorinda vendors include in the quote
Frequently Asked Questions
Yes — at Lafayette Community Park's reservable group picnic area (the city's flagship inflatable-friendly venue). You'll need a picnic reservation, a vendor with liability insurance, sandbag anchoring (no stakes), and a generator on-site since the park doesn't supply power. Call Lafayette Parks & Recreation at (925) 284-2232 to check availability.
No. The Lafayette Reservoir is operated by EBMUD (East Bay MUD), not the City of Lafayette, and EBMUD prohibits inflatables at all Reservoir picnic sites — including the 50-person and 200-person reservable areas. This is the most common point of confusion in Lafayette. If you want a bounce house, book Lafayette Community Park instead.
Lafayette city parks don't supply electrical power for inflatables. You need a 5,500W running-watt generator (sufficient for the blower) on-site for the duration of the rental. Most established Lamorinda vendors include the generator in their quote — confirm rather than assume. This is different from Concord, Pleasanton, and other inland cities where some parks provide power.
No city permit required for inflatables on private residential property in Lafayette. Lamorinda's typical lot is generous — most Lafayette homes comfortably fit a 15×15 standard bouncer or a 30×15 combo unit. Standard requirements: 110V outlet within 50–100 feet, 3 feet of clearance, no overhead obstructions. No generator needed for backyard setups (your house outlet is sufficient).
A standard bounce house in Lafayette runs $185–$285 for a full day with delivery and setup. Combo units (bounce + slide) are $320–$475; water slides are $345–$575; obstacle courses are $425–$800. If you're setting up at Lafayette Community Park, add the group picnic reservation fee separately (call (925) 284-2232 for current pricing). Lamorinda pricing sits a touch above Concord and matches Tri-Valley rates.
Reservations open one year ahead. Group picnic applications must be processed and paid at least 30 days before the event date — so block out a 30-day buffer minimum. For summer Saturdays, book 3–6 months out. Off-season (October–April) is open most weekends with 4–8 weeks notice.
Three fallbacks: (1) Briones Regional Park (EBRPD, north of Lafayette off Bear Creek Road) allows inflatables under EBRPD's $75 permit — large natural park, more availability. Call 1-888-EBPARKS option 2. (2) Reciprocal Lamorinda vendors often serve Moraga and Orinda; both towns ban inflatables at city parks, so backyard is the only Moraga/Orinda option. (3) Concord's Concord Community Park (3 sites) is 15 minutes east — different city permit but spacious and inflatable-friendly.
Many vendors serve both, but the Lamorinda-specific operators know the local rules — sandbag-only anchoring, generator-required setups, and Lafayette Community Park's reservation quirks. When comparing prices, check whether the quote includes the generator (some include it for Lamorinda by default; others list it separately).
May through October. Lafayette's mild Lamorinda climate (high 70s to low 80s in summer) means almost no fog and almost no rain June through September. Slightly cooler than Concord and Walnut Creek, warmer than Berkeley or Oakland. Avoid November through February for the rainy season.
Possibly — Lafayette Parks & Rec evaluates alcohol on a per-event basis, often requiring a separate permit and possibly insurance riders for larger events. Smaller family birthday parties typically can't include open-bar setups. Check directly with Parks & Rec at (925) 284-2232 when you reserve the picnic area.
