I managed a studio for 25 years and this was an integral part of my job.
I had a contract of agreement between the Studio and the renter written up by an attorney.
A few things I thought were important:
List of 5 references and check them out!
Cash any checks prior to first rental
Review the contract and sign it with them
Proof of (their)liability insurance
Safety features/AED set up/911 policy
Proof of (their) CPR
Shoe restrictions, floor damage? ( we didn’t allow tap/hard soled shoes on floor)
Believe it or not I had to put a clause in stating: NO Candles, NO Glitter, NO Feathers allowed in side the studio!
Food policy are you going to allow food and drink?
