After a public hearing, the governing board of such city may adopt a local law to grant the exemption authorized pursuant to this section.

4.

If satisfied that the applicant is entitled to an exemption pursuant to this section, the assessor shall approve the application and such building shall thereafter be exempt from taxation and special ad valorem levies as provided in this section commencing with the assessment roll prepared on the basis of the taxable status date referred to in subdivision three of this section.

reduce the percent of exemption otherwise allowed pursuant to this section;

(ii)

limit eligibility for the exemption to those forms of new construction, reconstruction, alteration or improvement as are prescribed in such local law or resolution;

(iii)

provide that the exemption shall be applicable only to those improvements which would otherwise result in an increase in the assessed valuation of the real property but which consist of an addition, remodeling or modernization to an existing multiple residence structure to prevent physical deterioration of the structure or to comply with applicable building, sanitary, health and/or fire codes.
