The simplest way to do this is to define what a visitor means in your complex. It may be easier to add this as a ‘rule’ rather than a by-law as chummy has one quarter of the votes and can block any by-law changes. So get a definition ‘visitor’ with regards to parking a common definition is no more than six hours at a time on no more than two consecutive days – something like that.
Then hit the vistor with a Notice To Comply and let them fight it in the CTTT if they think they can get away with it – or face fines of up to $550.
If you and the other three owners collectively have the Unit Entitlements of more than 75 percent, you can and should make this a by-law – and consider adding an ‘excess parking” rental charge of $10 an hour for anyone who overstays.
