Single stair reform is something that helps in terms of making more family sized units (aka 'homes').

I saw the author of this book give a talk earlier this year and found his point of view pretty convincing: https://islandpress.org/books/building-people#desc

Single stair is one of the reforms I'd most like to see.

At the time 2 stair requirements were adopted it was vital, with devastating urban fires a common occurrence. We have so many new options for both preventing fire and keeping evacuation routes accessible for hours that it's no longer required.

The regulation has a huge impact on the layout and form it's possible to build, and I think it's a huge driver of the visceral reaction against apartment living in the US and Canada.

Being able to build 4-8 storey apartments on a single lot with a central stair where every unit has windows on at least 2 walls would be a game-changer for north american urban spaces and a pathway out of the housing crisis.

On the one hand, maybe, but on the other hand, apartments (with the same number of bedrooms for the same COL-adjusted price) in the US are enormous compared to those in Asia and in Europe. I think the real source(s) of the visceral reaction(s) is, in no particular order, Americans' prioritization of personal independence over pragmatism (and I don't mean that pejoratively, though it can get stubborn at times), America's fairly weak renter protections/regulations, and the poor build quality of many American apartments (with dogshit sound and climate-proofing). I think it's a mix of a fundamentally American aversion to adding an additional person telling you what to do with genuine issues in the paradigm where you're paying up the ass for heating/cooling because your landlord doesn't particularly feel like installing double-pane windows, and at the same time your neighbors and neighborhood are obnoxiously loud.
