If they found out, I bet your homeowner's insurance would cancel in a heartbeat.
@susieq : I agree.
I wouldn't want to be with the same insurance company as a neighbor that rents out their private pool.
Pool owners can still be sued. Insurance paying out. Everyone pays.
It's not worth all the inconveniences mentioned in the posts above.
Air BnB for your pool, renting by the hour. lol
