(a) "Rules" or "regulations" pertaining to a residential lease are defined as policies of the landlord affecting the maintenance, operation, or governance of the common areas of the premises, or concerning the general conduct of tenants in their use and enjoyment of the leased premises.
(b) A landlord, from time to time, may adopt a rule or regulation. It is enforceable against the tenant only if:
(1) its purpose is to promote the convenience, safety, or welfare of the tenants in the premises, preserve the landlord's property from abusive use, or make a fair distribution of services and facilities held out for the tenants generally;
(2) it is reasonably related to the purpose of which it is adopted;
(3) it applies to all tenants in the premises in a fair manner;
(4) it is sufficiently explicit in its prohibition, direction, or limitation of the tenant's conduct to fairly inform the tenant of what the tenant must or must not do to comply;
(5) it is not for the purpose of evading the obligations of the landlord; and
(6) the tenant has notice of it at the time the tenant enters into the rental agreement, or when it is adopted.
(c) If a rule or regulation is adopted after the tenant enters into the rental agreement that works a substantial modification of the tenant's use of the leased premises, it is not valid unless the tenant consents to it in writing. In the case of any variance between the lease and a rule or regulation, the lease prevails.
