Bounce house rules in Maryland: permits, inspection, and insurance
State-regulated. Inflatables have their own dedicated chapter of the state code.
Informational only. Informational only, not legal advice. Amusement-device rules change between legislative sessions, and several of the entries here record changes made in the last three years. The binding authority is the agency named on this page. Confirm the current rule with them before you set up.

Permit or registration
Yes. An owner may not operate an amusement attraction unless it has been registered, inspected, and a certificate of inspection issued. Annually, by 1 April, each owner registers all existing certified attractions that will operate that year. New attractions are registered as soon as practical, or at least 30 days before anticipated operation. The Commissioner issues a state registration number and sticker for each registered inflatable, which must be on site in a readily visible location. Maryland states that no registration or inspection fees apply.
Inspection
An inspection request form must be submitted at least 5 business days before the scheduled operation date for an inflatable, against 30 days for mechanical attractions. The owner must also run a daily pre-opening inspection program covering tie-downs, anchors, blowers and electrical systems; automatic and manual safety devices; control devices; fencing, gates and guardrails; the structure, supports and wiring; entrances, exits, stairways, ramps and the surrounding area; and the communication system.
Insurance required by the state
Yes. Liability insurance of not less than $200,000 for injury to persons for non-mechanical, meaning inflatable, attractions, against $350,000 for mechanical attractions. A certificate of insurance must be furnished to the Commissioner before a certificate of inspection issues.
Operator requirements
The daily pre-opening inspection must be performed by a qualified person.
We could not confirm whether a separate attendant standard applies. Ask the Safety Inspection Unit at the Maryland Department of Labor.
What an operator should know
Maryland has the most inflatable-literate rulebook we found. The dedicated chapter reads as though it was written by someone who has actually staked down a bounce house: the daily inspection list names tie-downs, anchors and blowers rather than gesturing at "the device". Note the unusual combination of real obligations and no fees, and a $200,000 insurance floor that is well under what most commercial inflatable insurers write anyway, so the state minimum is not the number that will constrain you.
Frequently asked questions
What does it cost to register an inflatable in Maryland?
Nothing. Maryland states that no registration or inspection fees apply, which is unusual for a program with this much substance in it.
When is the Maryland annual registration deadline?
1 April, for all existing certified attractions that will operate that year. New attractions are registered as soon as practical, or at least 30 days before anticipated operation.
How much notice does Maryland need for an inflatable inspection?
At least 5 business days before the scheduled operation date, against 30 days for mechanical attractions.
How much insurance does Maryland require for a bounce house?
Not less than $200,000 for injury to persons for non-mechanical attractions. That is well below what most commercial inflatable insurers write, so your policy will likely exceed it.
Sources
Every claim above traces to one of these. Where a source is marked as one we could not open, nothing on this page rests on it: it is listed so you can try it yourself.
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.
Keep the paperwork with the unit
Permits, inspection dates and certificates belong next to the unit they cover, not in a folder. BounceDay keeps each unit’s record with its bookings, so the certificate a venue asks for is one tap away on the delivery. Your checklists are your own templates; the safety standards in them are yours, not ours.
Rules change between sessions. Confirm the current position with the Safety Inspection Unit at the Maryland Department of Labor before you set up.
