  like multiple dwellings erected after such date.
2. If there are bulkheads, superstructures or penthouses exceeding ten
  feet in height or exceeding in aggregate area ten per centum of the area
  of the roof, the measurement of height shall be taken to the top of such
  bulkhead, superstructure or penthouse, except that this shall not  apply

  walls and ten feet from the rear walls of  the  dwelling  and  at  least
  three  feet  from  any  court  wall.  Such penthouses shall have a clear

4. Any non-fireproof old-law tenement five stories in  height  may  be
  increased  in  number  of  stories to six provided that such increase in
  number of stories does not result in an increase in the  height  of  the
  roof  beams  above the curb level. In any tenement so altered, the first
  floor above the lowest cellar, or, if there  be  no  cellar,  above  the
  basement or other lowest story, shall be fireproof. Any yard or court of
  such  altered  tenement  shall  not  be  less  in any dimension than the

2023 New York Laws › MDW - Multiple Dwelling › Article 7-C - Legalization of Interim Multiple Dwellings › 280 - Legislative Findings.

§ 280. Legislative findings. The legislature hereby finds and declares
  that  a serious public emergency exists in the housing of a considerable
  number of persons in cities having a population  of  over  one  million,
  which emergency has been created by the increasing number of conversions
  of  commercial  and  manufacturing  loft  buildings  to  residential use
  without compliance with applicable building codes and laws  and  without
  compliance   with  local  laws  regarding  minimum  housing  maintenance
  standards; that many such buildings do not conform to minimum  standards
  for  health,  safety  and  fire  protection;  that  housing  maintenance
  services essential to maintain health, safety and  fire  protection  are
  not  being provided in many such buildings; that as a consequence of the
  acute shortage of housing as found and declared in the emergency  tenant
  protection  act  of  nineteen seventy-four the tenants in such buildings
  would suffer great hardship if forced to relocate; that as a  result  of
  the  uncertain  status  of  the tenancy in question the courts have been
  increasingly  burdened  with  disputes  between  landlords  and  tenants
  regarding  their  respective  rights  and obligations under the existing
  circumstances; that some courts have declared such buildings "de  facto"
  multiple dwellings; that illegal and unregulated residential conversions
  undermine the integrity of the local zoning resolution and threaten loss
  of  jobs  and  industry;  that  the  intervention of the state and local
  governments is necessary to effectuate legalization, consistent with the
  local zoning resolution, of the present illegal living  arrangements  in
  such  "de  facto"  multiple dwellings, and to establish a system whereby
  residential rentals can  be  reasonably  adjusted  so  that  residential
  tenants can assist in paying the cost of such legalization without being
  forced  to relocate; that in order to prevent uncertainty, hardship, and
  dislocation, the provisions of this article are necessary  and  designed
  to protect the public health, safety and general welfare.
2023 New York Laws › MDW - Multiple Dwelling › Article 7-C - Legalization of Interim Multiple Dwellings › 282-A - Applications for Coverage of Interim Multiple Dwellings and Residential Units.

§  282-a.  Applications for coverage of interim multiple dwellings and
  residential units. 1. Where any occupant has filed  an  application  for
  coverage  pursuant to this article and has received a docket number from
  the loft board, it shall be unlawful for an owner to cause or intend  to
  cause such occupant to vacate, surrender or waive any rights in relation
  to  such  occupancy, due to repeated interruptions or discontinuances of
  essential services, or an interruption or discontinuance of an essential
  service  for  an  extended  duration  or  of  such  significance  as  to
  substantially  impair  habitability of such unit, at any time before the
  loft board has made a final determination, including appeals, to approve
  or deny such application. This section shall not  grant  any  rights  of
  continued  occupancy  other  than  those  otherwise  granted by law. Any
  agreement that waives or limits the benefits of this  section  shall  be
  deemed  void as against public policy. In addition to any other remedies
  provided in this article for failure to be  in  compliance,  in  article
  eight  of  this  chapter,  or in the regulations promulgated by the loft
  board, an occupant who has filed an application with the loft board  for
  coverage  under  this  article may commence an action or proceeding in a
  court  of  competent  jurisdiction,  which  notwithstanding  any   other
  provision  of  law  shall  include the housing part of the New York city
  civil court, to enforce the provisions of this section.
2. It  shall  be  unlawful  for  any  owner  to  interrupt,  deny,  or
  discontinue  essential  services,  or  to  impair the habitability of an
  interim multiple dwelling unit or building. In addition to any  remedies
  provided  under this article, regulations promulgated by the loft board,
  or any other law or regulation  governing  the  housing  standards,  any
  occupant  of  an  interim  multiple  dwelling  may commence an action or
  proceeding in a court of competent jurisdiction  which,  notwithstanding
  any  other  provision  of law, shall include the housing part of the New
  York city civil court, to enforce the provisions of  this  section.  Any
  agreement  that  waives  or limits the benefits of this section shall be
  deemed void as against public policy.
2023 New York Laws › MDW - Multiple Dwelling › Article 7-C - Legalization of Interim Multiple Dwellings › 283 - Occupancy Permitted.

§  283.  Occupancy  permitted.  Notwithstanding any other provision of
  this chapter or any other law, code, rule or regulation,  occupancy  for
  residential  purposes  of  residential  units covered by this article is
  permitted, if such occupancy is in compliance with this article. Nothing
  contained herein shall be construed  to  limit  local  authorities  from
  issuing vacate orders for hazardous conditions, if appropriate.
2023 New York Laws › MDW - Multiple Dwelling › Article 7-C - Legalization of Interim Multiple Dwellings › 287 - Alternative Compliance.

§  287.  Alternative compliance. In any case in which a local building
  code or this chapter provides an alternative means of meeting  the  fire
  and  safety standards of article seven-B of this chapter, an owner of an
  interim multiple dwelling may, to the extent  permitted  by  such  local
  code or this chapter, elect to comply with the standards of such code or
  this  chapter  rather  than with article seven-B. Such an election shall
  not affect an owner's obligations to meet the deadlines  for  compliance
  set  forth  in  this  article,  and  in  such cases references herein to
  article seven-B shall be deemed to include any such local building  code
  or the applicable provisions of this chapter.

§  290.  Tenant  protections  in inhabited basement dwelling units and
  inhabited cellar dwelling units.  1.  The  program  authorized  by  this
  article  shall require an application to make alterations to legalize an
  inhabited basement dwelling unit or inhabited cellar  dwelling  unit  be
  accompanied  by  a certification indicating whether such unit was rented
  to a tenant on the  effective  date  of  this  article,  notwithstanding
  whether the occupancy of such unit was authorized by law. A city may not
  use  such  certification  as  the  basis  for  an enforcement action for
  illegal occupancy of such unit, provided that nothing contained in  this
  article  shall  be  construed  to  limit such city from issuing a vacate
  order for hazardous or unsafe conditions.
2. The local law authorized by  this  article  shall  provide  that  a
  tenant  in  occupancy at the time of the effective date of this article,
  who is evicted or otherwise removed from such unit as  a  result  of  an
  alteration  necessary  to  bring  an inhabited basement dwelling unit or
  inhabited cellar  dwelling  unit  into  compliance  with  the  standards
  established  by  the  local law authorized by this article, shall have a
  right of first refusal to return to such unit as a tenant upon its first
  lawful occupancy as a legal dwelling unit, notwithstanding  whether  the
  occupancy  at  the  time  of  the  effective  date  of  this article was
  authorized by law.  Such  local  law  shall  specify  how  to  determine
  priority when multiple tenants may claim such right.
3.  A tenant unlawfully denied a right of first refusal to return to a
  legal dwelling unit, as provided pursuant to the local law authorized by
  this article, shall have a cause of action in  any  court  of  competent
  jurisdiction  for  compensatory  damages  or  declaratory and injunctive
  relief as the  court  deems  necessary  in  the  interests  of  justice,
  provided  that  such  compensatory  relief  shall  not exceed the annual
  rental charges for such legal dwelling unit.
