What about the use of common property parking spaces by members of the general public, i.e. who are not residents, lot owners or their visitors …
Three words, Mike: pop-up bollards. Give residents identical keys so that only their genuine visitors can access the spaces.
Either that or a sign saying “Warning: cars parked here without permission have been vandalised in the recent past. Park illegally at your own risk.”
Not sure if that’s strictly legal … but it’s fun.
