Yes, this.
That's the only thing that matters. If the lease doesn't say you can't, then you can. If it says you can't, then time to look for a new airport if they start to enforce that clause. No point in vilifying the dude who is insisting that you make good on your agreement to not store that stuff in your hangar.
Insurance, as was pointed out, could indeed be a driver for this, but what's important is what the lease says.
As a side note, some of you might find it interesting to know that it's reasonably common to have someone *live* in your hangar in Mexico (depends on the airport, of course). In return for free or cheap housing, they keep an eye on things, keep things clean, pull the plane out, let people into the hangar so you don't have to go to the airport and do it yourself. That sort of thing. So, in short, the kinds of prohibitions mentioned in this thread basically don't exist there.
