Hey Struggler, All,
Struggler my opinion is to advise your friend to put their hand up for the EC and I think they may kill two birds with one stone. Stir up and motivate a stale or ignorant Committee to hold all residents to abide by the bylaws and then that should stop the illegal parking. You need no other reason than the fact that the CP is being used for FREE and illegally. Breach of bylaw. As well as all the reasons you mention above. Yes there are consequence. My building has had numerous parking issues and we have found that really staying on the backs of parking thieves with letters and threats from our manager does eventually work but they do start nice and end up nasty.The type of people that park illegally do not shift easily. (this totally relies on the efforts of a cohesive and functional committee) By the 3rd nasty letter with threat of fines and CTTT they tend to park elswhere!
Best of Luck CBF
