When you had Americans building the homes in CA they usually knew how to compensate for it. Commercial construction in CA uses higher quality workers in most cases. For example - in Nor Cal the Costco uses wood roof trusses to flex for earthquakes. In Florida they use steel roof trusses.
Pedro “ain’t” slap dashing commercial buildings in many cases because if it falls down - a lot of people could get killed and sued.
True true.
