Full details are outlined in our Terms of Service.

Date changes requested more than 14 calendar days before your event may be accommodated if availability allows.

We rent by the day, not the hour.

Your booking includes up to 8 hours of active golfing time within a 10-hour window. Setup and breakdown do not count toward those hours.

We do not offer reduced pricing for shorter events, as the majority of our cost is in design, logistics, delivery, and staffing.

Additional golfing time beyond 8 hours may be accommodated when possible at $50 per half-hour increment.

Overtime will be accomodated whenever possible. Our day rental includes up to 8 hours of golfing time in a 10 hour period. (For example, two sessions of 4 hours.) If you book us for 8 hours, and want more time last-minute, we'll accomodate if possible, at a rate of $50 per half hour.

If you booked us for 4 or 6 hours, for example, and want more time last-minute, the overtime is free of charge until you hit 8 hours of service time. The golf attendant will decide if they can stay later than expected or not.

If you know ahead of time you want us for more than 8 hours, we’ll add the extra hours onto your invoice after you book and pay your deposit, at the rate of $50 per half hour.

We offer no-fee delivery within 150 driving miles of Berkeley, California, covering all 9 Bay Area counties and areas such as Sacramento and Santa Cruz.

Our premium mobile mini golf experience was designed with weddings and corporate events in mind - but we’re happy to bring it to birthdays, private parties, other celebrations and events.

The average hole is under 3 feet wide and 11-14 feet long, with some L- and T-shaped designs that are a lot wider.

For comfortable guest flow, we recommend a minimum of 900 square feet dedicated to the course, although we can certainly expand to fill 1500 square feet. Less may work; more is preferred — especially for higher guest counts. Example layouts are shown on our layout page.

We can spread the course across multiple rooms or combine indoor and outdoor spaces. Photos of your venue in advance are extremely helpful so we can plan ahead for the best layout.

Since we just launched, we only built the first 9 hole course, so that’s all we’re offering as a standard bookable package. But if you want less than all 9, email us - and we’ll try and make it work, and get you a reasonable quote asap!

We may or may not add bookable packages in the future for 3 or 6 holes, for example, as well as additional add-ons that we’re dreaming up…

Yes, reasonably flat.

We can level for up to approximately a 2% slope. Beyond that, we cannot guarantee ideal ball roll.

We can set up on hardwood, concrete, tile, grass, gravel, and similar surfaces. If the floor can handle normal furniture, it can handle our equipment. We use rubber feet to protect hard flooring.

Yes. The course works beautifully indoors or outdoors on level surfaces.

The course can accommodate a throughput of approximately 36-56 guests per hour, depending on speed of play and group size.

Mini golf is designed to be open during most or all of your event. For weddings and formal events, you decide when it closes temporarily so guests don’t miss key moments.

Setup typically takes 60-90 minutes, and breakdown takes 45-60 minutes, but this varies widely depending on venue access.

Please inform us during the booking process about stairs, elevators, long walks, parking limitations, or difficult access so we can plan accordingly.

Yes. We provide an on-site attendant for the duration of service - often Jacob, who built the entire course.

The attendant manages guest flow, oversees equipment, and enhances the guest experience by interacting with guests in an engaging, non-intrusive way.

Please remember that Perfect Nine is not a childcare service, and guardians remain responsible for supervising minors.

Our initial 9-hole course was designed to appropriate in any setting: weddings, corporate events, or any party where you want to go absolutely above and beyond! Get in touch if you want to discuss custom themes or decor, or you’d like branded or personalized scorecards and signage. For now, we don’t have a set price add-on for custom options, but we’d love to work with you to create an exceptional experience that suits your needs.

All ages. While many of our events are adult-focused, the course is designed to be fun for kids, adults, golfers, and non-golfers alike.

Yes. All equipment is inspected between events in order to repair any wear or damage, and keep everything safe.

We carry event-appropriate liability insurance and can provide proof of insurance to venues upon request at no additional charge.

No. We carry our own liability insurance, so we do not require clients to provide insurance that covers Perfect Nine. However, clients remain responsible for guest supervision and conduct.

The course is fully playable in rain and is built to withstand rainstorms.

We do not provide automatic refunds or rescheduling for weather. However, we will work with you to adjust layouts, move indoors if possible, or explore practical solutions when available.

Normal wear and tear is expected and not charged. Accidental damage of up to $750 in value is also not charged, since we understand mistakes happen.

Accidental damage exceeding $750 in value, intentional damage, and equipment taken or lost by guests may be invoiced to the event host in accordance with our Terms of Service.

Damage is rare, as the course is staffed - but we do reserve the right to invoice when appropriate.

Absolutely yes, but full disclosure… we’re biased!

Our handcrafted course is designed to be elegant, engaging, and cohesive with upscale events.

We recommend booking as early as possible, especially for peak dates and weekends.

Online booking is currently available for dates up to one year in advance. For events less than two weeks away, please contact us directly for availability. We’re working towards building a second 9-hole set in the future, in order to be able to provide more service on in-demand days. If your preferred date is not available to book online, reach out to us, and we’ll see if we can accommodate you anyway!
