§ 226-c. Notice of rent increase or non-renewal of residential tenancy. 1. Whenever a landlord intends to offer to renew the tenancy of an occupant in a residential dwelling unit with a rent increase equal to or greater than five percent above the current rent, or the landlord does not intend to renew the tenancy, the landlord shall provide written notice as required in subdivision two of this section. If the landlord fails to provide timely notice, the occupant's lawful tenancy shall continue under the existing terms of the tenancy from the date on which the landlord gave actual written notice until the notice period has expired, notwithstanding any provision of a lease or other tenancy agreement to the contrary. 2. (a) For the purposes of this section, the required notice shall be based on the cumulative amount of time the tenant has occupied the residence or the length of the tenancy in each lease, whichever is longer.

(b) If the tenant has occupied the unit for less than one year and does not have a lease term of at least one year, the landlord shall provide at least thirty days' notice.

(c) If the tenant has occupied the unit for more than one year but less than two years, or has a lease term of at least one year but less than two years, the landlord shall provide at least sixty days' notice.

(d) If the tenant has occupied the unit for more than two years or has a lease term of at least two years, the landlord shall provide at least ninety days' notice.
