You are wise to ask these questions. Places to get accurate answers are:
1. The city hall's planning, zoning, permits - building inspector's office. Safety rules and regulations apply to all our communities around pools. Expect an inspection from the city, so that they can give you the information you need for your unique property. Signs, fences, locked gates and noise ordinances may apply to your public safety checklist.
2. Your insurance agent. In addition to your business insurance, you may need a liability rider for the pool.
3. Your attorney can advise you on this waiver contract idea, and if it is a good one, can write you one that can cover your risk.
I hope this is helpful. Definitely cover your risks here!
