Upon the adoption of such a local law, non-residential real property, upon conversion to mixed-use property, shall be exempt from taxation and special ad valorem levies as provided for in subdivision four of this section. 4. (a) (i) For a period of twelve years from the approval of an application, the increase in assessed value of such property attributable to such conversion shall be exempt as provided in subparagraph (ii) of this paragraph.

(i) such conversion was commenced subsequent to the date on which the municipality's local law took effect; and
(ii) the cost of such conversion exceeds the sum of ten thousand dollars or such greater amount as may be specified by local law.
(c) For purposes of this section the term conversion shall not include ordinary maintenance and repairs.
(d) No such exemption shall be granted concurrent with or subsequent to any other real property tax exemption granted to the same improvements to real property, except, where during the period of such previous exemption, payments in lieu of taxes or other payments were made to the local government in an amount that would have been equal to or greater than the amount of real property taxes that would have been paid on such improvements had such property been granted an exemption pursuant to this section.

Such exemption shall be granted only upon application by the owner of such real property on a form prescribed by the commissioner. Such application shall be filed with the assessor of the municipality or county having the power to assess property for taxation on or before the appropriate taxable status date of such municipality or county. 6. If the assessor is satisfied that the applicant is entitled to an exemption pursuant to this section, he or she shall approve the application and such real property shall be exempt from taxation and special ad valorem levies as in this section provided. The assessed value of any exemption granted pursuant to this section shall be entered by the assessor on the assessment roll with the taxable property, with the amount of the exemption shown in a separate column. 7. (a) During the period of exemption pursuant to this section, the owner shall submit an annual certification to the assessor attesting that the property complies with the provisions or requirements of this section and any additional provisions or requirements as may be provided by local law. Failure to submit such certification shall result in revocation of benefits. Such certification shall include at a minimum the following:

(iv) the specific address of the entrance through which the public enters the portion of the building used for commercial purposes;
(v) if the portion of the building intended to be used for commercial purposes is not currently in active use for such purposes and open to the public, the reasons why it is not currently being used for commercial purposes and open to the public; and
(vi) all such other information required by the municipality.
(b) If the assessor is satisfied that the applicant continues to be entitled to the exemption pursuant to this section, the assessor shall approve the certification and the real property shall remain exempt from taxation and special ad valorem levies for another year as provided in this section. 8. (a) The benefits of this section shall be revoked upon a finding by the assessor that:
(i) the application for benefits hereunder or the annual certification required hereunder contains a false statement or false information as to a material matter or omits a material matter;
(ii) the eligible real property fails to comply with one or more of the provisions or requirements of this section or any provisions or requirements provided by local law; or
(iii) the portion of the property devoted to commercial purposes has not been in active use for commercial purposes and open to the public for three consecutive years.
(b) Such revocation shall require the repayment of any benefits previously granted pursuant to this section for any year during which the property was non-compliant or the application or annual certification contained a false statement or false information as to a material matter or omitted a material matter.
(c) No benefits may be revoked unless the applicant has been given thirty days' notice of such revocation and has been given reasonable notice to cure any failure to comply with the provisions of requirements of this section. 9. If the assessor determines that there was a material misstatement in an application filed by or on behalf of the owners for an exemption pursuant to this section and that such misstatement provided the basis for the granting of such exemption, the municipality shall proceed to impose a penalty on the applicant of one thousand dollars in addition to recovering the amount of any prior exemption granted.
