I live in a basement apartment as a separate unit from the upstairs, but I exclusively have access to the panel for the whole house. Muwahaha. The upstairs unit has sole control of the thermostat however. Oh, and said panel is all of 20-24" away from my kitchen sink, that's some nifty stuff as well. Lucky for the neighbours upstairs, we happen to be old work friends, which makes it much less awkward on the occasional breaker trip. House parties are a lot easier too. I would hate to think what this place would be like with seperate tenants who didn't know eachother.
