Oh, Eric, please don't take this the wrong way. I almost sort of laughed for a minute, because it sounds so absurd. But, no, I don't think it is funny for you. This would seem to be a challenging situation for you.
Have you contacted your association management? What do they say?
The permitted uses will depend upon the by-laws, rules and regs of your association. Hopefully, there is cooperation and respect for the rules. If not, the only recourse is a remedy through the legal system.
I might suspect that such use would not be permitted, but it really doesn't matter what I might expect. It matters what the rules are, and if this person is breaking the rules, and next, what support the association provides if there is a violation.
Good Luck and I do empathize with you.
