Montana Title 70. Property § 70-33-313. Lot rules

(1) A landlord may adopt a rule concerning the rental occupancy of a lot and the use of common areas and facilities in accordance with 70-33-311. A rule may not be unreasonable, and a rule that does not apply uniformly to all tenants of a similar class creates a rebuttable presumption, as defined in 70-33-431(3), that the rule is unfair.

(2) Each common area facility must be open or available to residents at all reasonable hours, and the hours of a common recreational facility must be posted at the facility.
