Party Equipment Rentals in St. Louis: What to Ask Before You Book

Revised August 17, 2026

Imagine it’s the middle of April and the graduation party in Affton just became your problem. The date is fixed. Forty-some people said yes. The backyard is a backyard — a grill, a swing set, a patch of grass that has never held a crowd.

Maybe your version is a fall wedding on a rented lawn in St. Charles, where the ceremony chairs have to be dry at four o’clock. Maybe it’s a church picnic in Florissant, a company family day in Maryland Heights, or a sixtieth birthday in Belleville where half the guests will not stand for three hours. Same phone call.

Here’s the part nobody warns you about. Picking the tent is the easy half. The half that decides how the day runs is a short list of questions asked before any money changes hands.

What should you ask before you book party equipment rentals?

Six questions, before the deposit. What is the delivery and pickup window? Does the crew set up and tear down, or is this a drop-off? What surface will the tent sit on? What is the weather and cancellation policy, in writing? Who pulls the permit? And what does the damage waiver actually cover?

Those six aren’t arbitrary. They map to the six ways a rental goes sideways. The truck shows up at 7 a.m. Saturday when you wanted Friday. The chairs land stacked on the driveway and setup was extra. The tent can’t be staked because the only flat ground is asphalt. It rains and the deposit is gone. An inspector wants a permit nobody applied for. Get the answers by email.

What size tent do you need for 100 guests?

For 100 guests seated at round tables, plan on roughly 1,200 square feet of tent — a 30x40 is the bare minimum, and most rental companies will move you up to a 40x60 once you add a buffet line, a bar and any dance floor. A standing cocktail crowd of 100 fits in far less, closer to 600 square feet, because nobody needs a chair or a place to set a plate.

The arithmetic is simple enough to do yourself. Companies size from square feet per person, not headcount: roughly 12 square feet for a guest at a round table, about 8 for ceremony rows, 5 or 6 for standing. Multiply, then add the footprint of anything that isn’t a person.

What size tent do I need for 50 guests? Half the people, roughly half the ground: about 600 square feet seated, which puts a 20x30 at the floor and a 20x40 in comfortable territory. Give them the guest count, the seating style and the extras, then ask them to confirm it fits your yard with room to stake.

What are the most rented items for parties?

Tables, chairs, linens and tents carry most of the volume in this trade, in that order. They are what nearly every event needs, which is why a rental yard’s chair count is the truest measure of how big it is.

After that come the things that make an event feel finished. Sidewalls and tent lighting for anything running past dusk. Cocktail tables, which quietly reduce how many chairs you need. Chafing dishes, ice tubs, dance floors, portable restrooms for open ground. Heaters in October and fans in July, both of which sell out the same week the weather turns.

Then the family category: inflatables, concession machines, yard games and a sound system somebody’s uncle will take over. If the party is for kids, the bounce house gets booked first — and it carries the most rules.

Does the price include setup, or is it a drop-off?

Ask directly, because both are common and they price differently. A drop-off means the crew unloads at the curb and leaves; you carry, unfold and stack. Full setup means they place the tables, open the chairs, stake the tent, and return to break it down. Plenty of companies do setup on tents and drop-off on everything else.

Then pin down the window. Most companies deliver on a range, not a time — a four-hour block, sometimes an all-day one. For a Saturday event that often means a Friday delivery and a Monday pickup, and that weekend-long possession is baked into the rate whether you use it or not. Say so up front if your park shelter has to be clear by dark.

Do you need a permit for a tent in St. Louis?

Inside the City of St. Louis, yes, above a size threshold. The city’s tent and temporary structure policy requires a permit for tents greater than 800 square feet in total area, including multiple tents attached to one another with an aggregate area greater than 800 square feet. Any tent that affects, covers or obstructs a required means of egress needs approval regardless of size. Tents under 800 square feet that block nothing are exempt, as are tents for a private family event on the same residential lot.

Notice where that leaves a 20x40. It is exactly 800 square feet, right on the line, and attaching a 10x10 caterer’s canopy puts the aggregate over. Two other city rules catch people out: fabric has to be flame resistant with a certificate, and tents must be placed on grass so they can be staked — not on pavement. If your only flat ground is a parking lot, the conversation shifts to ballast, and ballast means weight, labor and a different price.

Outside the city limits, the threshold is whatever the local building or fire office says it is — St. Louis County, St. Charles County, Kirkwood and the Illinois municipalities all run their own. Ask the rental company who pulls it. Good operators handle it routinely, but the customer is responsible for all permits is a real sentence in real contracts.

Wildly off-topic — the graduate needs a haircut before the photos.

Do bounce houses need a permit in Missouri or Illinois?

This is a genuine state-line split, and it matters if your event is in Belleville rather than Ballwin. Illinois regulates inflatables by name: the Illinois Department of Labor’s Amusement Ride and Attraction Safety Division lists inflatable attractions — moonwalks and bounce houses — among equipment that must be inspected before initial operation and annually after, with a permit decal affixed to each unit. Illinois permits run the calendar year.

The rule follows public use, not the equipment. IDOL’s FAQ is explicit that someone who rents an inflatable for a private party does not need a permit; the obligation sits with the owner operating it publicly. IDOL also sets a minimum operator age of 16 and a $1,000,000 per occurrence, $2,000,000 aggregate insurance requirement for permitted operations.

Missouri is different. Its Amusement Ride Safety Act, at RSMo 316.203, defines an amusement ride as mechanical devices that carry passengers, dry slides over 20 feet, trams and motorized wagons, bungee attractions, and climbing walls over 10 feet. Inflatables are not named. So in Illinois, ask to see the current decal. In Missouri there is no state decal — ask instead for the certificate of insurance, the manufacturer’s posted rider limits, and whether an attendant stays.

What happens if it rains on the day of your event?

Usually the event goes on and the deposit does not come back. Most rental contracts treat a deposit as non-refundable once equipment is loaded, since the item was off the shelf and unavailable to anyone else. That is why the tent is the rain plan rather than a casualty of it.

Three things to settle in writing: how late you can move the date and whether the deposit travels with it, what happens if the crew judges conditions unsafe, and whether sidewalls can be added last minute. Wind is the real decision point, not rain — crews will strike or refuse to raise a tent in gusts, and no reputable operator negotiates that.

If the site is a park, a rented lawn or one of the campgrounds around St. Louis, check its own rules on staking and vehicle access first.

How can I reduce the cost of party rentals?

Shrink the tent, shrink the chair count, and widen the delivery window — in that order. Those are the three biggest levers, and none of them costs you anything the guests will notice.

It helps to know what drives the number. Tent size and anchoring is the largest single factor: staking into grass is quick, ballasting on pavement adds weights, labor and time. A tight delivery window costs more than a flexible one. Weekend dates carry a premium in peak months because inventory is finite. Damage waivers are usually a percentage add-on, so they scale with everything else on the order.

Practical cuts: move the buffet and the bar outside the tent so you are not renting square footage to shelter a table. Swap a third of the seating for cocktail tables. Use one vendor rather than two delivery fees. And ask what is already going out that weekend — a size sitting idle sometimes prices better.

How far ahead should you book for graduation and wedding season?

As soon as the date is fixed, and earlier than feels necessary. Late April through early June is graduation season across the metro, and September and October carry the fall weddings. Those weekends are when tent inventory runs out first, and a rental yard cannot conjure a second 40x60 the way a caterer adds a tray.

Chairs and tables usually survive a late request. Tents, dance floors, heaters and specialty linen colors do not. Weekday and Sunday dates hold availability much longer. If the event is a wedding, the rental calendar and the bridal shop timeline in St. Louis run on the same months, and both reward booking early for the same reason: finite stock, fixed dates.

Are event rentals profitable?

They can be, and the shape of it surprises people. The American Rental Association’s May 8, 2026 forecast, built with S&P Global Market Intelligence, put the U.S. event rental industry on track to grow 8 percent in 2026 to $6.1 billion. But the margin isn’t where customers assume. A big frame tent is capital that pays back across seasons, not on one weekend. Linens carry the best percentage and the worst labor, because somebody launders and folds every one between events. The money is really made or lost on the truck — how many stops a two-person crew clears in a window.

The year is made in two stretches, graduations and fall weddings, and January is quiet enough to hurt. What operators grumble about is short: the Saturday-in-May call placed ten days out, and the tent booked for a driveway that cannot be staked. Since this search starts with a category and a location, a complete, current directory listing is how a yard gets found.

Frequently asked questions

Is it cheaper to rent a tent or a venue?

A tent is cheaper on the invoice and more expensive in everything else. A venue rolls tables, chairs, restrooms, power, parking and a rain plan into one number. A tent covers ground and nothing more, so the honest comparison adds everything you put under it plus the labor of running the day yourself.

How much does it cost to rent a 20x20 event tent?

Ask for a written quote rather than trusting a number off the internet. The same 20x20 prices differently depending on how it is anchored, how tight the delivery window is, and whether the date falls in peak season. Staking into grass is cheapest; ballasting on pavement adds weights and labor. Sidewalls, lighting and the damage waiver move it further.

How much do chair rentals typically cost?

Chairs price per chair, and that figure is only part of it. Style matters most — a white folding chair, a resin garden chair and a wooden crossback are three tiers. Then delivery, whether the crew sets them out or leaves them stacked, the waiver, and quantity. Ask for the all-in total, delivered.

Is it cheaper to buy or rent a bounce house?

Renting wins unless you use one many times a year. A purchased inflatable brings storage, a blower, cleaning, patching and the setup you were paying someone else to do. It also brings the liability: a rental company carries insurance, checks anchoring, and in Illinois must hold a current state permit for public use.

Are bounce house rentals worth it?

For a party with young kids it is usually the one item that earns its price, because it occupies the guests you were most worried about. The value drops fast if the yard is wrong — not enough flat space, no anchor points, a long carry from the truck. Confirm footprint, power and surface before booking.

What age is appropriate for a bounce house?

Go by the unit, not a general rule. Every commercial inflatable carries a manufacturer placard listing age, height and weight limits and the maximum riders at once, and that placard governs. The practical rule operators use is to keep sizes separated, since little kids and big kids bouncing together is where injuries come from.

Where can I rent an event tent in St. Louis, MO?

Search party equipment rentals by your municipality rather than the whole metro, since delivery zones and fees are drawn tightly around a company’s yard. A vendor twenty minutes closer often quotes better than a bigger name across the river. Ask each the same three things: tent size, anchoring, and their written weather policy.
