(4) Such request shall, unless otherwise
specified by the tenant, remain in effect for the duration of such tenant's
tenancy. The owner shall maintain a record of all cash receipts for rent for at
least three year sunless a longer period is required by other provisions of
this Code.
(5) If a payment of rent
is personally transmitted to an owner, the receipts for such payment shall be
issued immediately to a tenant. If a payment of rent is transmitted indirectly
to an owner, a tenant shall be provided with a receipt within fifteen days of
such rent payment.
(6) If an owner
or an agent of an owner authorized to receive rent fails to receive payment for
rent within five days of the date specified in a lease agreement, such owner
shall send the tenant, by certified mail, a written notice stating the failure
to receive such rent payment. The failure of an owner or an agent of the owner
authorized to receive rent to provide a tenant with a written notice of the
non-payment of rent maybe used as an affirmative defense by such tenant in an
eviction proceeding based on the non-payment of rent.
