In the event that a unit is rendered uninhabitable under the provisions of § 6501.2, DCHA shall abate the tenant's total tenant payment in proportion to the seriousness of the damage and loss in value as a dwelling, in the event that repairs are not made as provided for in § 6501.2.
No abatement of rent shall occur if the tenant fails to cooperate with workmen seeking to make the repairs, rejects alternative accommodations, or if the damage was caused by the tenant, the tenant's household, or guests.
Evidence that a unit was uninhabitable under § 6501.2, and that abatement is required, may include a vacate order by a District Housing Inspector, or other substantial documentation.
