What is the name of your state? NY. The apartment I will moving into onSept 1st, in the lease it states any guests that will be staying for more than 7 days I need to get written permission from the owner, I have family coming for Christmas, 1500 miles away, they will be staying more than 7 days, the owner has already agreed to it, we have been having some problems with him lately and I told him I want it in writing they can stay, he is telling me he needs their license plate number for insurance and emergency reasons, I stated to him that myself as well as my family will just park on the street then, it wasnt stated in the lease I had to give him that info as well as their names and when exactly they would be coming and leaving. He stated under new york law the clause in the lease regarding guests would be held up by any court, and states that any court would agree that it is reasonable for the landlord to require this info. as he keeps saying it is in the lease. It only says in the lease more than 7 days needs written permission, nothing saying he would need all this other info. This is my family coming to visit for the holidays.
