There are many different types of properties. Condominiums and co-ops work very differently. If you are a condo owner and you give someone else your keys for 2 nights, you are violating the contractual rights of everyone else that owns property in the building and putting them at financial risk. The proprietor and state are the not the only parties involved.
that is definitely true for a co-op, and whether or not it is true for a condo is more up in the air. but I suspect you meant to say "co-op" where you said "condo".
Everything I've come to understand as a condo board president is that it is not "up in the air". Court cases have established precedent and we have reasonable by-laws. If we all collectively don't want it, we don't have to have it. Our lawyers tell us what we are doing is perfectly within our rights.
