St. Charles' Trusted Bounce House & Party Rental Company

Backyard Party Rentals is based in Wright City — about 30 minutes from St. Charles via I-70. We're not a metro STL company stretching west. We're your St. Charles County neighbors, and we've been delivering bounce houses, water slides, and party equipment to St. Charles families, schools, and churches since 2019.

St. Charles is the county seat, Missouri's first state capital, and home to 73,000+ residents. With 26 city parks, Historic Main Street, Frontier Park on the Missouri riverfront, two public school districts, Lindenwood University, and a year-round calendar packed with festivals — from the Festival of the Little Hills to Christmas Traditions — there's no shortage of events that need inflatables and party equipment.

What You Need to Know About Renting Inflatables in St. Charles, MO

St. Charles yards and neighborhoods: As the county seat and one of the oldest cities in Missouri (73,000+ residents), St. Charles has an incredible range of neighborhoods — from historic homes near Main Street and Blanchette Park to newer developments near Fountain Lakes and Fox Hill. Most yards easily accommodate our bounce houses and combos. Grass is our first choice for setup — we anchor with ground stakes for a secure hold. Each inflatable needs one standard 110v outdoor outlet within about 50 feet. No nearby outlet? We rent generators that keep everything running all day. We also set up on driveways, concrete, and indoor gym floors using sandbags.

Two school districts: St. Charles is served by the St. Charles School District — which operates St. Charles High School, St. Charles West High School, Lewis & Clark Middle School, Hardin Middle School, and six elementary schools — and parts of the Francis Howell School District, the top-rated district in the county with 16,000+ students across 23 campuses. Francis Howell holds graduation ceremonies at the Family Arena in St. Charles. We serve schools across both districts for field days, PTO carnivals, and end-of-year celebrations. Full liability insurance and COI provided at no charge.

St. Charles parks — 26 city parks: The City of St. Charles Parks & Recreation maintains 26 parks serving residents and visitors. Frontier Park sits on the Missouri riverfront at 500 S. Riverside Drive and is the city's premier event venue — home to the Festival of the Little Hills, Riverfest, and dozens of community events year-round. The Katy Trail runs right through it. Blanchette Park was the city's first park (acquired 1914) and features a playground, aquatic facility, shelters, and the Parks & Recreation office. Wapelhorst Park hosts athletic fields, a skate/BMX complex, and the city's soccer complex. DuSable Park offers a boat ramp, dog park, and trails along the Missouri River. Events at city parks may require a shelter reservation or special event permit — we'll provide our COI and any documentation St. Charles Parks & Rec needs.

St. Charles festivals: St. Charles is arguably the festival capital of the entire St. Louis metro. The Festival of the Little Hills (August, Frontier Park, three days, 100,000+ visitors) is one of the largest craft festivals in the Midwest. Christmas Traditions on Historic Main Street runs from Thanksgiving weekend through Christmas Eve with Victorian carolers, international Santas, and one-of-a-kind holiday charm — the festival has run for over 50 years. Riverfest (July 4th) features a morning parade on Main Street, carnival rides, and fireworks on the riverfront. Fête de Glace (January) is an ice-carving festival on Main Street. Legends & Lanterns (October) brings Halloween-themed walking tours through Historic Frenchtown. Our mechanical bull, obstacle courses, and inflatables are perfect for events of this scale.
