I don't know the pertinent CA laws, but in NY you can be fined for not shoveling snow off of your sidewalk and you are required to keep the sidewalk in good repair. If the sidewalk is broken and somebody trips, you can get fined by the city and/or sued by the ankle breaker. If it needs to be replaced, you're expected to do it yourself with your own money or be fined.
