If your landlord promises to make repairs, make sure that promise is in the written lease. Even if a landlord does not make a promised repair, the tenant should continue to pay the rent. Tenants have some recourse, such as going to small claims court, renegotiating lease agreement terms, moving or seeking the advice of a private attorney.
