Bounce house rules in Massachusetts: permits, inspection, and insurance

Who regulates inflatables in Massachusetts

Massachusetts Department of Public Safety, Office of Public Safety and Inspections (OPSI)

Authority: 520 CMR 5.00 (Amusement Devices), with inflatables at 520 CMR 5.09. Note the scoping: 520 CMR 5.02, 5.04, 5.05, 5.07 and 5.08 do not apply to inflatable devices, challenge courses or climbing wall facilities, except that 5.02(2) does apply.

Permit or registration

Yes, an annual license and permit. No person may manufacture or sell for use in the Commonwealth, operate, arrange for, or cause to be used, any inflatable device that is not in compliance with the inflatables rule. A license is valid for one year or until the insurance expires, whichever is sooner.

Inspection

Large inflatables need an annual inspection by a certified inspector before operation. Small inflatables need no pre-operation inspection by a certified inspector. State inspectors may inspect either type at any time during the season.

We could not confirm which of your units are "large" and which are "small". The definitions sit in a section we did not read, and they decide which rules apply to you. Ask the Office of Public Safety and Inspections.

Insurance required by the state

Yes. Large inflatables: $1,000,000 per occurrence and $2,000,000 aggregate. Small inflatables: $1,000,000 per occurrence. Certified inspectors must themselves carry $1,000,000 per occurrence.

Operator requirements

Yes. A ride operator must be at least 18 years old and have complete knowledge of the operation of the inflatable device. For large inflatables the owner must provide operators. For small inflatables an operator is optional but recommended.

What an operator should know

The large and small split is the whole game in Massachusetts: it changes the inspection duty, the aggregate insurance figure and whether you must staff the unit. The definitions of each sit in a section we did not read, so get them from the Office of Public Safety and Inspections before assuming a unit is small. Note also that the license expires when the insurance does, whichever comes first, so a mid-year policy change quietly shortens your license.

What to do with this

Knowing the rule is the first half. These four pages are the second half: registering the business, buying the coverage the rule assumes you carry, running a setup that would survive an inspection, and putting the terms in writing before a unit leaves the truck.

• Business license, LLC, and permits

  The registration layer under the device rules: the entity, the free EIN, the local business license, and sales tax on rentals.

• Bounce house rental business insurance

  Where the coverage limits on this page come from, what they cost, and why a general small-business insurer usually will not write inflatables at all.

• Safety and certification

  Anchoring, wind limits, supervision, and the ASTM standard most state inspection programs are written against.

• Free rental contract template

  The agreement that puts your terms, your weather policy, and the supervision rules in writing before a unit leaves the truck.

Rules change between sessions. Confirm the current position with the Office of Public Safety and Inspections before you set up.
