Some cities, towns, etc may require that the property owner maintain the sidewalks/curbs. I know property owner who had to pay out from a lawsuit due to a person tripping on the sidewalk and hurting themselves. It was a granite sidewalk and each slab was lifted and uneven. The City was held harmless since the property owner was held accountable for the repairs.

Also the property insurance may have to cover the damages.
