In order to collect a rent adjustment authorized pursuant to the provisions of subdivision d of section 26-510 of this chapter an owner must file with the state division of housing and community renewal, on a form which the commissioner shall prescribe, a written certification that he or she is maintaining and will continue to maintain all services furnished on the date upon which the emergency tenant protection act of nineteen seventy-four becomes a law or required to be furnished by any state law or local law, ordinance or regulation applicable to the premises. In addition to any other remedy afforded by law, any tenant may apply to the state division of housing and community renewal, for a reduction in the rent to the level in effect prior to its most recent adjustment and for an order requiring services to be maintained as provided in this section, and the commissioner shall so reduce the rent if it is found that the owner has failed to maintain such services. The owner shall also be barred from applying for or collecting any further rent increases. The restoration of such services shall result in the prospective elimination of such sanctions. The owner shall be supplied with a copy of the application and shall be permitted to file an answer thereto. A hearing may be held upon the request of either party, or the commissioner may hold a hearing upon his or her own motion. The commissioner may consolidate the proceedings for two or more petitions applicable to the same building or group of buildings or development. If the commissioner finds that the owner has knowingly filed a false certification, it shall, in addition to abating the rent, assess the owner with the reasonable costs of the proceeding, including reasonable attorneys' fees, and impose a penalty not in excess of two hundred fifty dollars for each false certification. The amount of the reduction in rent ordered by the state division of housing and community renewal under this subdivision shall be reduced by any credit, abatement or offset in rent which the tenant has received pursuant to section two hundred thirty-five-b of the real property law, that relates to one or more conditions covered by such order.
