This whole bit about "safety," is a result of speculative building, which accounts for the vast majority of residential construction in this country. You're never going to change that, and if you want something that's going to work, you're going to have to pay for it. Stop the delusion that just because someone makes a claim, that it will work. Know, don't assume. If there is a domicile you are considering buying laying within in a region with certain risk factors, assume that it does not meet the requirements to resist failure, and have someone qualified in assessing such things do that for you. You may also need to do some type of retrofit, or outright demolition and a complete rebuild.
You don't have a fucking clue about what this is about, Joshie, so take whatever you think is your opinion, and cram it up your ass.
