(1)(a) When premises are rented for an indefinite time, with monthly or other periodic rent reserved, such tenancy shall be construed to be a tenancy from month to month, or from period to period on which rent is payable, and shall be terminated by written notice of twenty days or more, preceding the end of any of the months or periods of tenancy, given by either party to the other.

     (b) Any tenant who is a member of the armed forces, including the national guard and armed forces reserves, or that tenant's spouse or dependant, may terminate a rental agreement with less than twenty days' notice if the tenant receives reassignment or deployment orders that do not allow a twenty-day notice.

     (2) Whenever a landlord plans to change any apartment or apartments to a condominium form of ownership or plans to change to a policy of excluding children, the landlord shall give a written notice to a tenant at least ninety days before termination of the tenancy to effectuate such change in policy. Such ninety-day notice shall be in lieu of the notice required by subsection (1) of this section. However, if after giving the ninety-day notice the change in policy is delayed, the notice requirements of subsection (1) of this section shall apply unless waived by the tenant.
