(f) Right to Stay. If the landlord fails to give the required written notice of nonrenewal of a rental agreement as provided in subsection (e) of this section, the tenant may not be evicted for up to (i) 180 days after the date on which written notice is given to the tenant for a year-to-year lease or a lease lasting a period of greater than a year, (ii) 120 days after the date on which written notice is given to the tenant for a lease lasting a period of not less than one month nor equal to or more than one year, and (iii) 30 days after the date on which written notice is given to the tenant for a lease lasting a period of one month or less, regardless of the termination date specified in the notice or in an existing rental agreement. Until the end of the relevant notice period, the terms and conditions of the tenancy shall be the same as the terms and conditions during the month of tenancy immediately preceding the notice; provided, however, that if rent was waived or abated in the preceding month or months as part of the original rental agreement, the rental amount during such relevant period shall be at the rate established on the last date that a full rent payment was made.
