If the pool is part of a HOA (Homeowner’s Association) complex, the association has rules that must be followed by the homeowners.
I lived in a So Cal neighborhood with a HOA. Homeowners paid quarterly dues, which paid for the maintenance of the common areas, including the pool. The dues covered the salaries of the Clubhouse Manager and staff, lifeguards, pool maintenance, etc. This property was for use by homeowners…and occasionally their guests. The HOA limited the number of guests a homeowner could invite.
Infants and toddlers who were not potty trained were not allowed in the main pool. (There was a kiddies’ pool, as well.) If a child had an “accident” in the pool (feces), the pool had to be closed. The pool maintenance personnel would have to add large amounts of chemicals to the pool and there were county regulations pertaining to the pool’s water having to completely circulate a certain number of times, before the pool could reopen.
I worked in the clubhouse office, and more than once had to ask non members to leave the property. Made no difference who they were. We even caught employees of local office complexes, sneaking in and using the pool. They were asked to leave. If they refused or gave us a hard time, we “trespassed” them, notifying the Sheriff’s Dept. that we would press charges if they showed up at the clubhouse again.
I don’t know whether or not the pool in McKinney, TX, had lifeguards. Safety becomes a concern…and a legal liability when the too many people try to use the pool at the same time.
The officers in the video were doing their job.
