> There is no plausible 'consumer protection' story that would explain why building codes for permanent residence are not good enough for temporary residence as well.

Your home is your home, so if you die in a fire it's your look out.

But a hotel, or a temporary residence, is not your home, and if you pay money to someone to provide a service they should meet minimum standards for safety.

This is a good thing. It allows small businesses to compete but without using "safety" as an area which can be cut.
