May I suggest that you allow your friends to handle the situation. It's quite possible that the property owner isn't aware. You may be jumping to conclusions. I'm sure there's a simple solution.
Also it's Sumter County code to have an outside light mounted within 4' of the back door. At least that's what we were told last year when we had the lanai enclosed. The light comes on automatically and is tripped by a motion detector. I can only adjust the length of time the two 75 watt flood lights stay on at the fixture. And when it comes on the Space Shuttle can see TV.
Happy New Year
