Well you can police the stuff that will happen, put up cameras, drive there more, become brilliant at property management, but you will see them litter the place more, leave busted up cars there more, stuff on the curb (fines), make more noise, be more destructive.   

Underestimated how dirty something that looks clean on camera can be. 

@Marshall Henry set up a camera now!

If not, might put a camera on that meter (and maybe others) to see what is going on. 

Cameras change the game, pure and simple, especially cameras with digital recording, night vision, web upload capabilities, motion detection spotlights.

It may take some time, and she may signal to the cameras and have a bouncer throw you out, but if you keep at it, you'll find one who will go for it.

Remote Video Guarding strengthens parking security by expanding the real-time monitoring perimeter with dispersed cameras that can instantly alert remote operators and on-site staff to potential issues before incidents occur.Remote monitors can verbally confront potential bad actors using on-location audio or notify law enforcement with video-verified detection which generates response as much as five times faster than an unverified alarm.COMMON SPACESShared amenities like lounges, rooftops and pools inevitably draw occupants after hours.

Much better than what I currently have.I’ve actually thought about putting a camera up in the parking lot to capture how often the car is there.I’ll start with the written letter first reminding the tenant of the lease.

Within a few hours of rejecting the offer I have camera footage of the person walking the property with a local town official.

But basically he wanted to rent my property and then offer it as STR to whoever.I said I didn't want it to be trashed (again) and he talked endlessly about how he puts up cameras, other security, knows exactly who is going in & out, cleaners are the finest, etc.
