The record supports DHCR's finding that petitioner had improperly imposed a rent increase for certain claimed improvements that its documentation did not substantiate (see, Matter of Birdoff Co. v. DHCR, 204 A.D.2d 630). Petitioner was not entitled to demand a hearing in lieu of producing adequate documentation. Nor was petitioner entitled to a hearing on the issue of whether the overcharge was willful. There being adequate support and a rational basis in the record for DHCR's finding that petitioner failed to establish the nonwillfulness of the overcharge, treble damages were properly imposed (see, Matter of Century Tower Assocs. v. DHCR, 83 N.Y.2d 819).
THIS CONSTITUTES THE DECISION AND ORDER OF SUPREME COURT, APPELLATE DIVISION, FIRST DEPARTMENT.
