(c)   For   purposes   of   this   section   the  terms  construction, reconstruction, alteration and improvement shall  not  include  ordinary maintenance and repairs.   3.  Such exemption shall be granted only upon application by the owner of  such  building  on  a  form  prescribed  by  the  commissioner.  The application  shall  be filed with the assessor of such city on or before the appropriate taxable status date of such city.   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. 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.   5.  In the event that a building granted an exemption pursuant to this section ceases to be used primarily for residential  purposes  or  title thereto  is  transferred  to other than the heirs or distributees of the owner, the exemption granted pursuant to this section shall cease.    6. (a) The enactment of a local law in such city may:  (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 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.  (b)  No  such  local  law  shall reduce or repeal an exemption granted pursuant to this section until the expiration of the  period  for  which such exemption was granted.   7.
