The three-day notice under RPAPL 711 (2) is by its terms a "demand of the rent * * * requiring, in the alternative, the payment of the rent, or the possession of the premises.” There can be no misunderstanding that both sections 2525.1 and 2205.1 unequivocally forbid "any person to demand or receive” rent in excess of the legal regulated rent or maximum rent (emphasis supplied). Under these provisions it is necessarily unlawful to demand the payment of legal fees, collection costs, and/or late charges in a written three-day notice. Where, as here, the wording of a statute or regulation is expressed in clear and unambiguous terms, it is the duty of the courts to enforce the law as written.
