Section 28-105.9. Expiration

All  permits  issued by the commissioner shall
  expire by limitation and become invalid if the permitted work or use  is
  not  commenced  within 12 months from the date of issuance of the permit
  or, if commenced, is suspended or abandoned for a period  of  12  months
  thereafter.  All  permits  for  work  in an area of special flood hazard
  pursuant to Appendix G of the New York city building code  shall  expire
  if  the  actual  state of permanent construction has not occurred within
  180 days from the date on which such permit is issued. The  commissioner
  may, however, upon good cause shown, reinstate a work permit at any time
  within  a  period of two years from the date of issuance of the original
  permit, provided that the work shall comply with all the requirements of
  this code and other applicable laws and rules  in  effect  at  the  time
  application  for  reinstatement  is  made, and provided further that the
  applicant shall pay all reinstatement fees as required by  article  112.
  The  permit  shall  automatically expire upon the expiration of required
  insurance or if the applicant holds a license issued by  the  department
  upon the expiration or revocation of such license during the term of the
  permit.
