If the owners association is anything like a condo board or a homeowners association in the US, they should have more than enough authority to enact whatever rules they want in their building. If they don't, maybe they can amend their bylaws so that they do. I do think that most bad behavior is already covered by existing laws. Yes, the guests might not care, but the owner ultimately has to own the place and answer to the local authorities and the owners association or whatnot. If there are constant complaints about your property, you're going to be held accountable for it, whether you live there or not.
