Unfortunately under the laws of all states in this country, the right to deduct rent is contingent upon making repairs to a unit where some item is a habitability issue such as lack of heat after giving the landlord notice of the problem.Unfortunately you cannot deduct for the costs for the take out food you have had to buy. You should be entitled to some rental rebate.Since your landlord is not responsive, I suggest that you make a complaint against him or her with the local health and safety department or the building and permit department as to the lack of a working stove.
