Right, but my view is that certain "qualifying events" should trigger public interest requirements for more safety.
Buying a house? Make sure stuff is up to code, get an inspector, but it's on you.
Housing kids for the state? There's a public interest in making sure they're safe.
Renting out a room or building? Safe thing (and there are already regulations here that are stricter than those applying to private he owners)
Renting out a room or house short term? Again, same thing. This should at least be the same as a long term rental.
EDIT: anyway, my original point was that there is precedence for safety regs even if you don't have long hallways or tall buildings.
