wheatcitygirl said "I don't really care who did it. It isn't in my way but will cause anyone who is walking down the sidewalk to go around it onto the street.
I just want to know if I would be held responsible if there was a complaint that it is blocking the city sidewalk in front of my house.
If I would be responsible then yes, I will contact the neighbor and have them fix the problem. "
think you answered your own question. If there is a complaint made, you, not the contractor will be held responsible for this.
That is why it would be helpful to know what contractor cleared their snow.
Chances are with how busy things are right now, IF the contractor was to come back to clear this, they're not going to be in any rush to get over to your residence.
