We had indoor parking at my workplace inside an egress stairwell. When the building inspector came to look at a plenum that had been run through, he saw the bikes and we got the boot. Nothing can be stored in an egress stairwell in my jurisdiction. We all park outside now
Thefts? So far so good. In fact, there was a theft from the stairwell, but none from the bike rack outside so far. (knock wood)
