Maintaining social distancing in a pool is naturally quite difficult. Thus, exercise of great caution should be exercised when deciding whether to reopen one. Not only are there different legal restrictions in different jurisdictions, insurance coverage may vary. You should seek legal counsel before making a decision. Regarding states’ restrictions, below are the restrictions currently in place in Ohio, Kentucky, and Indiana on the opening of pools.
