The Warranty of Habitability applies under both common law and state statutory law. What it means, in a nutshell, is that any landlord has a duty to make any quarters that he or she is renting, commercial or residential, livable. To make a property livable means to provide things such as working locks, windows that close, hot water, working electricity, in essence, to make the premises in clean working order. This also means that the landlord must paint regularly and make sure there is no mold on the walls. This list is not exhaustive, but provides a very short and general outline to a landlord’s duty to keep any premises that he or she rents livable.
