No, PeterC, this by-law may not apply, strictly speaking. But where do you start and stop in a situation like this?
What if there were a few more changes in tenancy and a couple more bikes for each unit? Can they all be allowed to be chained up round the common areas?
I reckon timilla should not be an uncaring absentee landlord and have the tenants play by he rules. It’s not hard for someone fit enough to ride a bike to carry it up stairs. Jerry Seinfeld does it in New York. I’m guessing they would rather clutter up the common property than their own apartment.
