Professional home builders are typically required to be tested before being licensed. A license is typically required in order to build homes for other people.
Which is the part I disagree with. Existing homes built under those outdated regulations are somehow magically safe but building the same home 20 years later makes it a death trap?
Existing homes aren't magically safe. Safe isn't a binary, it's a continuum, and we're constantly improving our building techniques. We don't have the resources to knock down all the older houses and rebuild them.
The least we can do is when building new houses is to make sure that they are safer so that over time buildings get safer and safer.
