(a) If the landlord fails to substantially conform to the rental agreement, or if there is a material noncompliance with any code, statute, ordinance or regulation governing the maintenance or operation of the premises, the tenant may, on written notice to the landlord, terminate the rental agreement and vacate the premises at any time during the first month of occupancy, so long as the tenant remains in possession in reliance on a promise, whether written or oral, by the landlord to correct all or any part of the condition or conditions which would justify termination by the tenant under this section.

(b) If the tenant remains in possession in reliance on a promise, whether written or oral, by the landlord, to correct all or any part of the condition or conditions which would justify termination by the tenant under this section;  and if substantially the same act or omission which constitutes a prior noncompliance, of which prior notice was given under subsection (a) of this section, recurs within 6 months, the tenant may terminate the rental agreement upon at least 15 days' written notice, which notice shall specify the breach and the date of termination of the rental agreement.
