In the event that a unit is rendered uninhabitable and repairs are not made as provided for in § 5758, the Project Owner shall abate the tenant's total tenant payment in proportion to the seriousness of the damage and loss in value as a dwelling.
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 § 5758, and that abatement is required, may include a vacate order by a District Housing Inspector, or other substantial documentation.
