If the DTF determines that the total annual income is in excess of $250,000, $175,000, or $200,000 in each of the two preceding calendar years, whichever applies as rovided in section 2211.2 of this Part, the city rent agency shall, on or before November 15th of the year in which DTF makes such determination, notify the landlord and tenants of the results of such verification. Both the landlord and the tenants shall have 30 days within which to comment on such verification results. Within 45 days after the expiration of the comment period, the city rent agency shall, where appropriate, issue an order providing that such housing accommodation shall not be subject to the provisions of the Rent Law and this Subchapter as of the first day of March in the year next succeeding the filing of the OPD with the city rent agency. A copy of such order shall be mailed by regular and certified mail, return receipt requested, to the tenant or tenants and a copy thereof shall be sent to the landlord. Where the DTF determines that the income threshold has not been met, the city rent agency shall issue an order denying the OPD. If the DTF cannot ascertain whether the threshold has been met, the city rent agency may issue an order denying the OPD, or request additional information.
