§7–306.

    (a)    In connection with a protected action, an owner:

        (1)    may not terminate or alter the terms and conditions of a lease entered into before the effective date of the protected action;

        (2)    may not interfere with the efforts of individual tenants to obtain housing subsidies or other public assistance;

        (3)    may not discriminate based on source of income or receipt of a housing subsidy;

        (4)    may not interfere with the rights of a tenant to occupy an assisted unit under an existing lease or applicable federal, State, or local law; and

        (5)    shall cooperate with a tenant to execute all necessary documents to enable the payment of housing subsidies to or for the tenant.

    (b)    If the owner has interfered with a tenant’s application for a housing subsidy or other public assistance, the nonpayment of any amount of rent for an assisted unit in excess of 30% of the tenant’s income is not grounds for the owner to terminate the lease or sue for possession of the leased property.
