1. If the department proposes to institute proceedings pursuant to this article, it may file a copy of the certification and a notice of intention to commence such proceedings in the office of the clerk of the county in which the dwelling is located. Such notice shall contain the names of all persons required to be served pursuant to this section and shall otherwise meet the requirements of subdivision (b) of section six thousand five hundred eleven of the civil practice law and rules. The notice shall be indexed by the clerk in the manner prescribed by subdivision (c) of section sixty-five hundred eleven of the civil practice law and rules for a notice of pendency of action and shall have the same effect as such notice. It shall expire one year after filing, if no proceeding pursuant to this article has been commenced. Except as otherwise provided herein, all of the provisions of article sixty-five of the civil practice law and rules shall be applicable to the notice filed pursuant to this article.2. The department shall serve upon the owner of the dwelling, a copy of the certification. Service shall be made personally or by posting in a conspicuous place upon the dwelling and mailing a copy by registered or certified mail to the last known owner at such owner's last known address. In the case of a dwelling subject to the provisions of section three hundred twenty-five of the multiple dwelling law, such mailing may be made to the last registered owner at his last registered address. The copy of the certification shall be accompanied by a notice stating that proceedings pursuant to this title may be instituted unless the owner notifies the department that the property has not been abandoned. Such notification shall be made by a showing that the conditions upon which the findings in such certification are based do not exist or have been corrected. Such showing shall be made not later than thirty days after the date of such notice.3. Within five days of the service of notice on the owner, a copy of the certification shall be served on each mortgagee, lienor and lessee of record, personally or by registered mail to the address set forth in the recorded instrument or, if no address appears therein, to the person at whose request the instrument was recorded. Such copy shall, in the case of a mortgagee or lienor, be accompanied by a notice that proceedings pursuant to this article may be instituted unless the mortgagee or lienor, within fifteen days of such mailing, either commences proceedings to foreclose the mortgage or lien or enters into an agreement with the department to bring the building into compliance with the applicable provisions of law.4. If the name or address of (a) the last owner of record; or(b) any owner, mortgagee, lienor, or claimant as shown on records maintained by any city official required by any local law to maintain records of persons entitled to notice or process in connection with the maintenance of in rem foreclosure actions;(c) the person listed as the owner of the property on the latest completed assessment roll, is different from that referred to in subdivisions two and three of this section, a copy of the notice to the owner, or to a mortgagee or lienor, whichever is applicable, shall also be sent to such person at such address by registered mail.N.Y.
