In our municipality, builders are required to install sidewalks only on one side of the street — and they must be cleared of snow by the homeowner. When we went looking for a home here, about 30 years ago, I specifically instructed the real estate agent to show me only houses on the non-sidewalk side of the street. (I pity those poor souls who live on corner properties.)
That was prescient;)
I believe the fines for non-compliance are $50. Not sure if that would be applicable for each snow event - like consecutive speeding tickets.
Seems like a warning would be the first reprimand. Law enforcement must have more important things to do.
