Planning a foam party in a San Francisco park? Be sure to check with the SF Recreation and Park Department for any required permits or restrictions on water usage and event sizes. Many neighborhood parks have specific rules to keep in mind, especially concerning ground cover and public access.
Delivery in San Francisco
Our team navigates the hills and one-way streets of SF with ease. We factor in typical delivery challenges like limited parking and the occasional steep driveway. Please ensure clear access for setup, especially for backyard events or locations with stairs, and let us know about any unusual gates or access codes in advance.
San Francisco event seasons
San Francisco's "summer" (June-August) with its classic fog often means surprisingly pleasant foam party weather – not too hot! September and October often bring the warmest, sunniest days. We generally avoid the wetter winter months but are happy to operate on any clear, 55°F+ day. Book early for spring and fall events!

Foam Party Rentals in San Francisco — FAQ
Do I need a permit for a foam party in a public park?
Yes, for most public parks in San Francisco, you will likely need a special event permit from the Recreation and Park Department. We recommend applying well in advance.
What about water and power for the foam machine?
Our foam machines require a standard 120V outlet and a garden hose connection within 50 feet. Please ensure you have access to both at your event location.
Can you set up in a typical small San Francisco backyard?
Absolutely! We specialize in making foam parties happen in diverse spaces. Just ensure you have enough clear, relatively flat space for the foam area and machine.
How much does a foam party cost?
Most foam party packages run $350–$800 for 1–2 hours of active foaming, including machine, foam solution, and attendant.
Is the foam safe for kids?
Yes — all reputable operators use hypoallergenic, biodegradable, tear-free foam solution that's safe for skin and clothes.
Does it stain or kill grass?
The foam is non-staining and biodegradable. Grass is fine — it usually rinses away with a hose.
