I notice quite a few condos have house rules which cut utility supplies such as electricity and/or water if maintenance fees are not paid.

Personally I think this is a good rule to ensure prompt payment. Otherwise people will not pay maintenance promptly and when the maintenance office has no money, the condition of the condo will go south. Everything will fall apart.

Anyone knows if this is a permissible rule from legal stand point ?

Also noticed some die hard condos which will NEVER cut water or electricity even if the maintenance have not been paid for years. The only thing they will religiously follow is to send legal letters. Legal letters costing money.

I see these condos are like infected by cancer. LOL.
