A photo booth rental business is one of the fastest event-rental niches to launch profitably: a single booth can book 2–4 events most weekends, each at $400–$900, with the same unit working weddings, corporate parties, birthdays, and school dances. The barrier to entry is low, the margins are strong, and demand has grown every year as couples and event planners treat the photo booth as a standard part of the event rather than an extra. This guide walks through exactly how to start a photo booth rental business in 2026 — what it costs, what equipment to buy, how to price, and how to get your first bookings.
