Thanks guys. I don't live in Denver anymore. I moved to the foothills (Kitteridge area) a couple years ago. I love it. I'm 3 minutes from fishing in Bear creek and the locals let me access private spots. I'm surprised this little creek can hold some decent fish. But at 7400 ft. it sure does snow a lot more and I need to worry more about bears than junkies. The lady who moved into my old house in Denver recently had her car stolen out of the driveway, so I get the security concerns. That is a good point.
Right now. this is not a very bad place to rob or trespass. My next-door neighbor breeds, trains, and competes German Shepard police dogs. They are mean! Well, they're nice to us but, I feel bad for the UPS and FedEx drivers. I'm not sure a door and deadbolt on a ADU are any less secure than the door and deadbolt on the main house but I need to think about this and an overall security plan. Every time I lock up my steel barn I always kind of do a head shake because all it would take to break into it is a screw gun. One could remove a wall panel in 2 minutes.
