(1) If there is a noncompliance by the tenant with the rental agreement or with a provision of 70-33-321 , the landlord may deliver a written notice to the tenant pursuant to 70-33-106 specifying the acts or omissions constituting the noncompliance and stating that the rental agreement will terminate upon the date specified in the notice that may not be less than the minimum number of days after receipt of the notice provided for in this section. The rental agreement terminates as provided in the notice for one or more of the following reasons and subject to the following conditions:
(a) nonpayment of rent, late charges, or common area maintenance fees as established in the rental agreement, for which the notice period is 7 days;
(b) a violation of a rule other than provided for in subsection (1)(a) that does not create an immediate threat to the health and safety of any other tenant or the landlord or manager, for which the notice period is 14 days;
(c) a violation of a rule that creates an immediate threat to the health and safety of any other tenant or the landlord or manager, for which the notice period is 24 hours;
(d) late payment of rent, late charges, or common area maintenance fees, as established in the rental agreement, three or more times within a 12-month period if written notice is given by the landlord after each failure to pay, as required by subsection (1)(a), for which the notice period for termination for the final late payment is 30 days;
(e) a violation of a rule that creates an immediate threat to the health and safety of any other tenant or the landlord or manager whether or not notice was given pursuant to subsection (1)(c) and the violation was remedied as provided in subsection (3), for which the notice period is 14 days;
(f) two or more violations within a 6-month period of the same rule for which notice has been given for each prior violation, as provided in subsection (1)(a), (1)(b), or (1)(c), for which the notice period for the final violation is 30 days;
(g) two or more violations of 70-33-321 (1) within a 6-month period, for which the notice period for the final violation is 14 days;
(h) any violation of 70-33-321 (3), for which the notice period is as provided in 70-33-422 (1);
(i) disorderly conduct that results in disruption of the rights of others to the peaceful enjoyment and use of the premises, for which the notice period is 7 days;
(j) any other noncompliance or violation not covered by subsections (1)(a) through (1)(i) that endangers other tenants or mobile home park personnel or the landlord or manager or causes substantial damage to the premises, for which the notice period is 14 days;
(k) conviction of the mobile home owner or a tenant of the mobile home owner of a violation of a federal or state law or local ordinance, when the violation is detrimental to the health, safety, or welfare of other tenants or the landlord or manager or the landlord's documentation of a violation of the provisions of Title 45, chapter 9, for which the notice period is 14 days;
(l) changes in the use of the land if the requirements of subsection (2) are met, for which the notice period is 180 days;
(m) any legitimate business reason not covered elsewhere in this subsection (1) if the landlord meets the following requirements:
(i) the termination does not violate a provision of this section or any other state statute; and
(ii) the landlord has given the mobile home owner or tenant of the mobile home owner a minimum of 90 days' written notice of the termination.
(2) If a landlord plans to change the use of all or part of the premises from mobile home lot rentals to some other use, each affected mobile home owner must receive notice from the landlord as follows:
(a) The landlord shall give the mobile home owner and a tenant of the mobile home owner at least 15 days' written notice that the landlord will be appearing before a unit of local government to request permits for a change of use of the premises.
(b) After all required permits requesting a change of use have been approved by the unit of local government, the landlord shall give the mobile home owner and a tenant of the mobile home owner 6 months' written notice of termination of tenancy. If the change of use does not require local government permits, the landlord shall give the written notice at least 6 months prior to the change of use. In the notice the landlord shall disclose and describe in detail the nature of the change of use.
(c) Prior to entering a rental agreement during the 6-month notice period referred to in subsection (2)(b), the landlord shall give each prospective mobile home owner and any tenant of the mobile home owner whose identity and address have been provided to the landlord written notice that the landlord is requesting a change in use before a unit of local government or that a change in use has been approved.
(3) Subject to the right to terminate in subsections (1)(d) through (1)(k), if the noncompliance described in subsections (1)(a) through (1)(c) is remediable by repairs, the payment of damages, or otherwise and the tenant adequately remedies the noncompliance before the date specified in the notice, the rental agreement does not terminate as a result of that noncompliance.
(4) For purposes of calculating the total number of notices given within a 12-month period under subsection (1)(d), only one notice for each violation per month may be included in the calculation.
