New York Real Property Law
Warranty of Habitability
1. In every written or oral lease or rental agreement for residential premises the landlord or lessor shall be deemed to covenant and warrant that the premises so leased or rented and all areas used in connection therewith in common with other tenants or residents are fit for human habitation and for the uses reasonably intended by the parties and that the occupants of such premises shall not be subjected to any conditions which would be dangerous, hazardous or detrimental to their life, health or safety. When any such condition has been caused by the misconduct of the tenant or lessee or persons under his direction or control, it shall not constitute a breach of such covenants and warranties.
2. Any agreement by a lessee or tenant of a dwelling waiving or modifying his rights as set forth in this section shall be void as contrary to public policy.
3. In determining the amount of damages sustained by a tenant as a result of a breach of the warranty set forth in the section, the court;
(a) need not require any expert testimony; and
(b) shall, to the extent the warranty is breached or cannot be cured by reason of a strike or other labor dispute which is not caused primarily by the individual landlord or lessor and such damages are attributable to such strike, exclude recovery to such extent, except to the extent of the net savings, if any, to the landlord or lessor by reason of such strike or labor dispute allocable to the tenant’s premises, provided, however, that the landlord or lesser has made a good faith attempt, where practicable, to cure the breach.
(c) where the premises is subject to regulation pursuant to the local emergency housing rent control law, the emergency tenant protection act of nineteen seventy-four, the rent stabilization law of nineteen hundred sixty-nine or the city rent and rehabilitation law, reduce the amount awarded hereunder by the total amount of any rent reduction ordered by the state division of housing and community renewal pursuant to such laws or act, awarded to the tenant, from the effective date of such rent reduction order, that relates to one or more matters for which relief is awarded hereunder.
