[EMJ]

Here's a question: Why did you even sign up for letting him have the place his senior year in the first place? Seems you and your sis set him up for all that's to come. Why not just let him tough it out at the dorms? You wouldn't have any of these control issues - that's what's basically going on here from his perspective. You "allow" him to stay there, but you attach conditions, albeit, they're reasonable ones. You're actually lucky he's not tearing up the place with his buds and girls and booze like most college kids.
