Lease Agreement unclear on Parking situation

[Melissa T.]

I am managing property for a client. The client would like their tenant to not use the garage as storage. She would like them to park their car in the garage. There are issues with congestion on the street and the house is a 3 family. One unit has been vacant for a long time and won't be for much longer. This is going to create an issue with cars at the house as she chooses to park outside the garage. Two cars will fit in the garage and one can be parked on the side by the vacant unit.

The problem I'm having is that the owners lease does not say that the address is a 1bdrm/1bathroom/with one car garage or really any identifying factors about what the signed lease agreement is for. My leases for other clients (hers will be updated when this one is ends) have specific property identifiers including how many spots, where (garage or off street), and what the property is in terms of bedrooms and bathrooms.

We told her to please park her car in the garage she complained the door slammed shut. We had a garage company come out and fix the door. We even offered to let her move her things into another area on the property. She responded she still doesn't want to park in the garage because it's not a motorized door with a button for her to press inside her car. She also said she doesn't want to move her things to the other area because of concerns about mildew.

Do I have a leg to stand on if her current lease says nothing other than the address about what she is leasing?

Input is appreciated. We're trying to play nice but she's not making it easy.

Thanks!
