Secondary Suites

I notice that the local lefty paper and politicians are on again about secondary suites.

They, and all planners, seem to have missed the point, which is the usage load on a property.

Who cares if a house with basement suite has an elderly retired couple upstairs and a single student down? I would care a great deal if my neighbor sold his house to a large family, say mother, father, brother in law, 3 teenagers and 2 little kids. They will of course be replete with 2 cars per adult and a motorcycle or two for the teens, plenty of friends, parties and all the usual accoutrements, such as a large smoky fire pit and multiple high speed comings and goings. They could be the nicest people in the world and they would still be overloading my neighbors house, which is a 2 bedroom bungalow.

And yet situation one is illegal and situation 2 is perfectly legal.

How about a bylaw that each occupant must have 500 square feet if an adult and 250 square feet if a child and that there be off street parking for all but 2 vehicles for any single residential building? Or something. Maybe create a point system with a by-law enforcement visit if there are egregious breaches by many points.
