Bounce House Rentals in Union City
Compare prices from East Bay vendors delivering to Union City — plus how Kennedy Park and 13 other reservable parks handle inflatables, the business-license-and-insurance rule, and premium-day fee notes
Union City is one of the more inflatable-friendly cities along the I-880 East Bay corridor — a family-heavy community of ~71,500 between Hayward and Fremont, with one of the densest reservable park networks in the East Bay. The City allows bounce houses at every reservable picnic site in the system (14 parks, 25+ individual sites), provided the vendor has a Union City Business License and General Liability Insurance on file at least 14 days before the event. That single rule shapes every park-based party decision in Union City.
Kennedy Park (1333 Decoto Road) is the flagship — five reservable picnic sites scaling from 32 to 130 capacity, an amphitheater, the Kennedy Youth Center, and the largest concentration of party activity in the city. For events of 60+ guests, Kennedy is the obvious choice; for smaller intimate parties, Veterans Memorial Park, Sea Breeze, or the smaller Old Alvarado/Cesar Chavez sites work well.
The fee structure has one quirk most renters miss: non-resident fees are doubled, and an additional doubled fee applies on premium days (Easter, Mother's Day, Father's Day, Halloween) and 10 named holidays. If your event lands on one of these days and you're not a Union City resident, the picnic site fee can quadruple compared to a regular Saturday. Plan accordingly.
Climate-wise, Union City sits in the East Bay Bay-side band — cooler than Concord and Pleasanton inland, similar to Hayward and Fremont. Summer highs in the high 70s, often with a Bay breeze that's especially noticeable in the afternoon. Spring and early fall are reliable; deep summer is warm but not punishing.

Union City Park Rules for Inflatables
Union City permits bounce houses at every reservable picnic site in the city park system — 14 parks with 25+ individual sites — provided the rental vendor has a Union City Business License and General Liability Insurance on file at least 14 days before your event. No alcohol or smoking at any park; sound amplification limited to two specific venues (Kennedy Park Amphitheater, Old Alvarado Gazebo). Premium-day and holiday fee multipliers apply.
Park reservation required for any inflatable
Bounce houses are only allowed at reservable picnic sites — not in general park grass areas or first-come pavilions. Reservations through the Kennedy Youth Center (1333 Decoto Road) or online at unioncity.org/reg. Residents can book up to 30 calendar days in advance; non-residents up to 60 days. Approval takes 24–48 hours; payment due within 24 hours of approval.
Vendor needs a Union City Business License + General Liability Insurance
Per Union City policy, bounce house vendors must have both a Union City Business License and General Liability Insurance on file at least 14 days before your event. If your vendor doesn't have these, the event won't proceed. Confirm with your vendor when getting a quote — established East Bay vendors typically already have UC licenses on file; smaller operators may not.
No alcohol or smoking at any park
Union City prohibits alcohol and smoking at every city park, period. No exception permits available. This is stricter than Concord and many other Contra Costa cities.
Sound amplification only at Kennedy Amphitheater + Old Alvarado Gazebo ($50)
Music and amplified sound permits are issued for only two locations in the city: Kennedy Park's Amphitheater and the Old Alvarado/Cesar Chavez Gazebo. The fee is $50. Anywhere else in the system, amplified sound isn't permitted (acoustic music and standard speakers at conversation volume are fine).
Premium-day fees: doubled on holidays and 4 premium days
Easter, Mother's Day, Father's Day, and Halloween are 'premium days' with doubled fees. Plus 10 named holidays trigger the same doubling. Non-resident fees are also doubled — so a non-resident booking on a premium day pays 4x the resident regular-day rate. Check the date carefully.
Non-resident fees doubled across the board
All site fees double for non-Union-City-residents on every date. A site that costs $50 for a resident is $100 for a non-resident; on a premium day it's $200. Bring your Union City utility bill or driver's license to claim the resident rate.
Refund policy not posted publicly — confirm at booking
The City's published reservation page doesn't post a specific refund schedule for picnic site cancellations. Confirm refund/transfer terms with the Kennedy Youth Center at (510) 675-5329 when you book.
Permits & Reservations
Gathering Permit
The picnic site reservation IS the city paperwork for an inflatable event in Union City. No separate inflatable permit form. The vendor's UC Business License + insurance must be on file 14 days before the event; you don't file these as the renter, the vendor does.
Special Event Permit
Larger Union City events (community festivals, large school carnivals, multi-vendor events) go through the Special Event Permit process. Most family birthday parties don't need this.

Frequently Asked Questions
Yes — at every reservable picnic site in the city park system (14 parks, 25+ sites), provided your rental vendor has a Union City Business License and General Liability Insurance on file at least 14 days before the event. Reservations through the Kennedy Youth Center at (510) 675-5329 or online at unioncity.org/reg.
Kennedy Park (1333 Decoto Road) is the flagship — 5 reservable picnic sites scaling from 32 to 130 capacity, plus the Kennedy Park Amphitheater for amplified music ($50 permit). For 60–80 guest birthdays, Site 4 or Site 5 at Kennedy is ideal; for smaller groups, Veterans Memorial or Sea Breeze work well. Old Alvarado/Cesar Chavez is a good cultural-themed venue with the Gazebo for music.
Two things, on file with the City at least 14 days before your event: (1) a Union City Business License and (2) General Liability Insurance. Most established East Bay vendors already have these for Union City. When comparing quotes, ask whether the vendor is on Union City's compliant-vendor list — if not, allow extra lead time for paperwork.
City policy. All Union City picnic site fees double for non-residents (residents prove Union City address with utility bill or driver's license). On top of that, premium days (Easter, Mother's Day, Father's Day, Halloween) and 10 named holidays trigger another doubling. A non-resident booking on a premium day pays 4× the resident regular-day rate. Plan accordingly — or shift to a non-premium weekend if budget matters.
No city permit required for inflatables on private residential property in Union City. Most homes — Decoto, Alvarado, Sugar Mill Landing, Pacific States — have lots that 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. Union City prohibits alcohol and smoking at every city park, period. No exception permits. This is stricter than most Bay Area cities. If alcohol is essential, you'll need a private venue or backyard.
A standard bounce house in Union City runs $165–$265 for a full day with delivery and setup. Combo units (bounce + slide) are $295–$450; water slides are $315–$525; obstacle courses are $395–$750. If you're at a city park, add the picnic site fee (doubled for non-residents and premium days) and $50 if you want amplified music at Kennedy Amphitheater or Old Alvarado Gazebo.
Residents: up to 30 calendar days in advance. Non-residents: up to 60 calendar days in advance. Approval takes 24–48 hours; payment is due within 24 hours of approval. For premium summer Saturdays at Kennedy Park, book at the very start of your eligibility window — those sites move fast.
Amplified music requires a $50 Sound Amplification Permit. The City only issues these for two locations: the Kennedy Park Amphitheater and the Old Alvarado/Cesar Chavez Gazebo. Anywhere else in the system, amplified sound isn't permitted (acoustic music and conversation-volume speakers are fine). If you need a DJ, book one of those two venues.
The City's public reservation pages don't post a specific refund schedule. Confirm refund/transfer terms with the Kennedy Youth Center at (510) 675-5329 when you book. Vendors typically have separate cancellation policies; ask both ahead of time, especially if booking 4+ weeks out.
May through October. July and August are the warmest (high 70s) with reliable afternoon Bay breeze. Cooler than Concord or the Tri-Valley, warmer than San Francisco. Almost no rain June through September. Avoid November through February for the rainy season.
