Good question. Ordinarily a written lease between a landlord and a tenant controls and governs the obligations owed the tenant by the landlord and vice versa in the absence of state law.You sent an e mail transmission to your landlord requesting certain repirs be made by him or her. You received a response from your landlord to your e mail. The repairs were not made. Whether or not you are entitled to terminate your lease due to the failure of the landlord to make timely repairs depends upon what your lease states as well as state law on the subject. Many states allow the tenant to make the repairs themselves up to a certain amount and deduct the amount of repairs made from the following month's rental.I suggest that you consult with a landlord tenant attorney further on the subject that you have inquired about.
