Tenants should speak to their building manager or landlord first to try to resolve any landlord-tenant complaints they have. If this does not lead to a resolution, such problems can usually best be addressed by your local town/city building department. This includes rodent or insect infestations and complaints about heat or hot water.
For information on getting help if your apartment, workplace, school or day care is too cold for comfort, visit the New York State heat regulations website.
Heat must be supplied from October 1 through May 31 to tenants in multiple dwellings. If the outdoor temperature falls below 55°F between the hours of six a.m. and ten p.m., each apartment must be heated to a temperature of at least 68°F. If the outdoor temperature falls below 40°F between the hours of ten p.m. and six a.m., each apartment must be heated to a temperature of at least 55°F (Multiple Dwelling Law § 79; Multiple Residence Law § 173; NYC Admin. Code § 27-2029). See VII. UTILITY SERVICES (page 23) of the Tenant's Rights Guide (New York Attorney General's Office)
