A. Heat: Failure to provide heat during seasons which require
heat. The landlord must provide and maintain a heating
system in good operating order. From September 16 to June
14, every room must be heated to at least 68 degrees between
the hours of 7 a.m. and 11 p.m. and at least 64 degrees
between the hours of 11:01 p.m. and6:59 a.m., unless the
tenant is required to supply the fuel under a written lease
agreement. During the heating season, the maximum heat
allowable is 78 degrees.
The landlord should supply heat and a gas on gas system is considered supplying the heat. You can ask the landlord if he will add some heating sources, but he/she is under no obligation to do it.
