I have been looking for a house to buy in SF for the last 6 months. What's been very interesting is that most of the houses we have reviewed, did not have solid foundations (many being 2-unit condos). They are all located in liquefaction zones and the disclosure packages mentioned the foundations had cracks (or needed retrofitting). Still, buyers did not care and bid huge amount of money. Our estate agent told us the average buyer does not take that into consideration nor care to retrofit the foundation. Scary.
