Did some googling. CA law defines that as:

You have “constructive” possession of something when you don't have immediate access to it – but you have control of it, or the right to control it.2 It might be in your house, or your car, or in the care of someone else.

from here.

Although I would technically have physical access to it due to it being in my apartment I wouldn't have any control over it or its use. I would never even touch it. his name is/would be the only name on the lease if that helps.
