(2) A person must not replace or alter any keyed lock, or place a new lock on the entrance of a dwelling unit, without first providing both the tenant and owner of that dwelling unit with a suitable functional key to operate the lock. A tenant must obtain permission from the owner, in writing, before installing a lock.
(3) (A) Every owner of a personal living quarters building or 2 or more contiguous rental dwelling units must alter the required deadbolt locks on all affected dwelling unit, personal living quarters, and individual living unit entrance doors between tenancies to protect against misuse of a master key or if the enforcing agency notifies the owner that the agency has reason to believe that a master key has been lost or stolen or is being used in the commission of a crime.

One door of each sliding door structure must be stationary and secured in place by screws or pins.
(5) Viewers. A viewer must be installed in each entrance or exit door to an individual living unit or rental dwelling unit, but a viewer need not be installed if a window, vision panel, or similar transparent device is located within 2 feet of the door and faces the external area in front of the door.
(6) Windows. Each openable window in an exterior wall of a rental dwelling unit, personal living quarters building, or individual living unit that is located within reach of the ground or any adjacent surface must be constructed and maintained to protect it from being opened from the outside and from being pried out of its frame or track.
