Snow Removal Requirements. When to Clear or let melt?

[Jack Barkow]

I'm just curious what everyone is doing with snow removal. Is there a certain depth of snowfall that you wait for to pay/DIY snow removal or do you do it regardless?  For example half an inch in Chicago like 20% of people clear their sidewalks and it just turns into slippery ice.  I could fall and sue them I guess, but it hasn't happened.  For my personal stuff is it just not worth the risk to wait for half an inch to melt/get icy and just spend the dough to have it done for every snowfall?
