Car slides on ice in parking lot hits building cause is negelect of property owner who is at fault for damage?

This will depend on where the ice came from. If the owner or employee of the parking lot property deposited Ice on the lot and then left the lot open for public parking, one might construe owner negligence. If Nature deposited the ice on the parking lot, such as an Ice storm or freezing temperatures, then it is very unlikely that the property owner or the vehicle owner could be construed as negligent or At Fault.
