§ 383. Construction  with  other laws; severability. 1. The provisions   of this article and of the uniform fire  prevention  and  building  code   shall  supersede any other provision of a general, special or local law,   ordinance, administrative code, rule or regulation  inconsistent  or  in   conflict therewith provided however:a.  Nothing  herein  shall  impair  the  validity  of any action taken   pursuant to or in compliance with such  law  or  regulation  before  the   effective date of the uniform code; andb.  Any improvement, modification, alteration, adaptation, redesign or   repair required by or pursuant to any general,  special  or  local  law,   administrative code, rule or regulation enacted and effective before the   effective  date  of  the  uniform  code  shall be made in the manner and   within the time so required.c. That, in cities with a population of over one million, the existing   building and fire prevention codes shall  continue  in  full  force  and   effect  beyond  January  one,  nineteen  hundred  eighty-four unless the   council, after analysis and consultation  with  the  building  and  fire   officials   of  such  cities,  shall  determine  that  said  local  code   provisions are less stringent than  the  uniform  code.  Existing  local   statutory,  regulatory  and  administrative  laws and provisions of such   cities shall continue in full force and effect unless the  foregoing  is   determined  by  the  council.  Notwithstanding this paragraph, when such   factory manufactured homes are intended for use as  one  or  two  family   dwelling  units  or  multiple  dwellings of not more than two stories in   height, provided such multiple dwellings are not  intended  for  use  as   hotels or motels, the provisions of this article and of the uniform fire   prevention  and  building  code pertaining to factory manufactured homes   shall supersede any other provision of general, special  or  local  law,   ordinance,  administrative  code,  rule or regulation inconsistent or in   conflict therewith.2. Nothing herein shall be construed as affecting the authority of the   state labor department to enforce a safety  or  health  standard  issued   under  provisions  of  sections  twenty-seven  and twenty-seven-a of the   labor law.3. Nothing  herein  shall  be  construed  to  relieve  a  person  from   complying  with  a stricter standard issued pursuant to the Occupational   Safety and Health Act of 1970, as amended.4. If any section of this article or the application  thereof  to  any   person  or  circumstances  shall  be  adjudged  invalid  by  a  court of   competent jurisdiction, such order or judgment shall be confined in  its   operation  to  the  controversy  in which it was rendered, and shall not   affect or invalidate the remainder of any provision of  any  section  or   the application of any part thereof to any other person or circumstances   and to this end the provisions of each section of the article are hereby   declared to be separable.
