> Things like dual staircase requirements, elevator size requirements, and sprinkler requirements make it extremely expensive to build any sort of housing.

And you want and need precisely that in a house with fluctuating occupants of which a high percentage will have some sort of mental health issue.

Cutting corners on boarding houses will lead to fire catastrophes.

Nobody denies this. The question is whether said fire catastrophes really claim more lives than homelessness and wintering on the street. (Obviously fire catastrophes are a bigger PR problem and get more media attention, but is that really the appropriate metric for human suffering?)

They don't, but fire catastrophes are one of the most gruesome ways to die - and worse, a fire can always spread around and endanger even more people. There are reasons why fire codes are among the oldest laws in humanity.

A good advice is to remember that in case of fire what kills people most of the times, is the smoke. Having extinguishers -and- breathing bottles could help. Maybe there is room for designing a new product that would act as two in one?.

No but here's the thing: for all of those regulations, the US still has more fire deaths than most of Europe. So they're not working anyway!
