Ah. So basically a multi-tier building code that builders/etc certify during their work? Makes sense - I'm not sure if there's an equivalent in USA or not. There are certainly minimums in most/all? places, but I have no idea how much consistency there is. The bigger problem is probably that there are a bunch of old, cheap buildings in places that experienced major housing booms during lax requirements, and those still exist :|
