the taxes of such city are levied.

(i) 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

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.

(b) No such local law shall reduce or repeal an exemption granted
