A landlord, from time to time, may adopt rules or regulations, however described, concerning the tenant's use and occupancy of the premises. Any such rule or regulation is enforceable against the tenant only if:

1. (a) Its purpose is to promote the convenience, safety, peace 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. (b) it is reasonably related to the purpose for which it is adopted;
3. (c) it applies to all tenants in the premises equally;
4. (d) it is sufficiently explicit in its prohibition, direction or limitation of the tenant's conduct to fairly inform the tenant of what such tenant must or must not do to comply;
5. (e) it is not for the purpose of evading the obligations of the landlord; and

6. (f) the tenant has notice of it at the time such tenant enters into the rental agreement.

   After the tenant enters into the rental agreement, if a rule or regulation which effects a substantial modification of the rental agreement is adopted, such rule or regulation is not enforceable against the tenant unless such tenant consents to it in writing.
