If the tenant proceeds under this subsection (f), he may not proceed under subsections (c) or (d). The tenant may not exercise his rights under this subsection if the condition was caused by the deliberate or negligent act or omission of the tenant, a member of his family, or other person on the premises with his consent. Before correcting a condition, the repair of which will affect more than his own dwelling unit, the tenant shall notify all other tenants affected and shall cause the work to be done so as to result in the least practical inconvenience to other tenants.
(g) Fire or Casualty Damage. If the dwelling unit or common area are damaged or destroyed by fire or casualty to an extent that the dwelling unit is in material noncompliance with the rental agreement or with Section 5-12-070, the tenant may:
(1) Immediately vacate the premises and notify the landlord in writing within 14 days thereafter of the tenant's intention to terminate the rental agreement, in which case the rental agreement terminates as of the date of the fire or casualty; or
(2) If continued occupancy is lawful, vacate any part of the dwelling unit rendered unusable by the fire or casualty, in which case the tenant's liability for rent is reduced in proportion to the reduction in the fair rental value of the dwelling unit; or
