Such a bylaw probably would be struck out.
Its a principle that a lot owner can do with his lot as he please ( within the law).
What is the difference between a lot owner renting out their apartment, versus renting out a parking space.
Of course you could get creative with a bylaw that specifies entry only by a security feature ( a key fob) issued by the OC once the registration of the vehicle is provided.
Of course to enforce this one would have to monitor the CCTV footage, as the fob could be passed on.
OR install a camera linked to your security system that only opens the door when a registered number plate is recognised.
