This sort of story is the #1 reason why, after careful consideration, I'll never run a crashpad. Tick off one neighbor, and with one phone call your business (which is an unlicensed boarding house, after all) is closed and you're dealing with fines, back taxes, and lord knows what else.

Chicago went through a spate of this a couple of years ago. If memory serves, local hotel interests decided to get some laws passed and enforced that targeted airline crash pads. The theory being, of course, that hotel revenues were suffering.

The irony is that 99% of all crash pads probably make better neighbors than most. Occupants are there to sleep, not to party or make heck.
