Reasonable notice to enter
I'm leasing a commercial property in Michigan. The landlord has entered 3 different times without notice. Our lease agreement states that they must give "reasonable notice" I was notified at 2 p.m. that she wants to enter tomorrow at 9 a.m. tomorrow morning and I refused because I won't be there and the last time she did it she left the doors open. At 4:00 p.m. the local police department contacted me that tomorrow at 9a.m. they will assist her with a locksmith to enter the premise. What is "reasonable notice" and is there a statue or some sort of landlord tenant act that I can copy and give to the local police department?
