True. Some people buy houses to "flip" them. And there are things that can be hidden. Like, a homeowner can use modern wiring and run 6" of it and tie it in to knob-and-tube wiring. They can cover up and hide foundation cracks or huge structural issues and the inspectors might never see it. Mike Holmes has a TV series where he helps people fix their homes that they bought after a home inspector cleared the place & missed major problems.
Also, some places get rented out. I had some tenants who lived in my house for many years & stopped paying rent (while we were overseas and couldn't do anything about it) bc they mistakenly thought they could get squatters rights to the place. They did a LOT of damage trying to DIY stuff-- tore out plumbing vents, messed up the plumbing, screwed up the wiring, destroyed the floors, etc. There are signs of some electrical fires that started & some of the outlets were missing. Even though they thought they were going to get to keep our home, they still treated it like garbage.
There are some homeowners who think the codes don't matter & just try to do things cheap and dirty (or easy). They don't realize/care that codes exist for a reason.
