What does liquefaction severity 6 mean for a lot when it is also on fault line? Does building department even allow to build there? If yes, how expensive is it going to be?

Very sparsely distributed minor ground effects include sand boils up to 0.5m (1.5 ft) in diameter, minor ground fissures with openings up to 0.1m (0.3 ft) wide, ground settlement up to 25 mm (1 in.). Effects lie primarily in areas of recent deposition and shallow groundwater surface, such as active floodplains.

Liquefaction is a very, very localized effect in landfill areas, and even more so on slopes where the hill slumps in 100 - 150 circles. Is stable for 1/4 mile, then slumps again. A few rains later, another hill (otherwise looking identical) slumps nearby - but then stays still for ten years.
In the 1989 earthquake when several buildings sunk their first and second floors into the land fill on the Bay side of the city, one building sunk 15 feet. the one next door did not move.
