Before correcting a condition affecting facilities shared by more than one dwelling unit, the tenant shall notify all other affected tenants and shall cause the work to be done so as to create the least practical inconvenience to the other tenants. Nothing herein shall be deemed to grant any tenant any right to repair any common element or dwelling unit in a building subject to a condominium regime other than in accordance with the declaration and bylaws of such condominium building; provided, that the declaration and bylaws have not been created to avoid the application of this chapter.
For purposes of mechanics' lien laws, repairs performed or materials furnished pursuant to this subsection shall not be construed as having been performed or furnished pursuant to authority of or with permission of the landlord.
(d) Failure to Maintain. If there is material noncompliance by the landlord with the rental agreement or with Section 5-12-070, the tenant may notify the landlord in writing of the tenant's intention to withhold from the monthly rent an amount which reasonably reflects the reduced value of the premises due to the material noncompliance. If the landlord fails to correct the condition within 14 days after being notified by the tenant in writing, the tenant may, during the time such failure continues, deduct from the rent the stated amount. A tenant shall not withhold rent under this subsection if the condition was caused by the deliberate or negligent act or omission of the tenant, a member of the tenant's family, or other person on the premises with the tenant's consent.
