I can't stop thinking about this. We're pursuing zero fire risk in multifam, while tolerating much more in single-fam. People respond by building and living in single-fam, where they're exposed to not only one of the highest fire death risks in the developed world, but also TONS more car crash risk

Thanks! The fire-fatality disparities were wild. Fire-death rate 18x higher in pre-1970 single family than post-2010 apartment. But only new apartments (and occasionally townhouses) are getting stopped by fire-safety concerns.

Pew finds something that everybody in codes and standards knows but few will say out loud: we apply far stricter fire safety standards to apartments than to houses. www.pew.org/en/research-...

In part 2 of our series on misaligned incentives in housing policy, the UCLA Housing Voice Podcast speaks with @stephenjacobsmith.com about the high cost of elevators in North America, and the negative consequences for affordability and accessibility. www.lewis.ucla.edu/2025/09/24/9...

Episode 98: Elevators with Stephen Smith (Incentives Series pt. 2)

Elevators in the U.S. and Canada cost 3–5x as much as in other high-income countries. Stephen Smith explains how our well-intentioned standards make cities less safe and accessible.

Well said. And this research shows why reforms like Colorado's are crucial. Regional housing supply drives local rents 4x more than supply within a municipality, so statewide reforms are necessary--there's just no way to get to widespread affordability solely through local action.

Governor Jared Polis @colorado.gov · Aug 18

A new @pewtrusts.org analysis shows restrictive zoning drives up rent and worsens hardships. The U.S. is short 4–7M homes. Breaking down barriers—like parking mandates and outdated zoning—can lower costs and help more Coloradans achieve homeownership.
www.pew.org/en/research-...

Article clipping from the Pew Charitable Trust with text next to it reading, “findings from an analysis done by the Pew Charitable Trust found that not allowing for more homes to be built pushes up rent prices across the board and increases hardships on low-income residents and neighborhoods.”

White text on black background reads: “Colorado is lowering housing costs and removing government barriers. Governor Polis signed landmark laws to allow more housing near transit, cut red tape, and expand options like ADUs, transit-oriented communities, starter condos, and smart-stair apartments, while ending discriminatory occupancy limits and costly parking requirements.

And one more... regional housing supply drives local rents 4x more powerfully than supply within localities on average, so state laws to allow more homes are absolutely necessary to improve housing affordability, even when some localities act.

Alex Horowitz @alexhrwtz.bsky.social · Jul 31

And the converse is also true. Rents have been falling fastest for older, naturally affordable (Class C) apartments in metro areas that have added the most housing.

Alex Horowitz @alexhrwtz.bsky.social · Jul 31

Turns out there's no tradeoff between housing abundance and affordability for low-income renters- the opposite in fact. Rents have risen 10 pts more during the shortage in low-income neighborhoods than high-incomes ones. www.pew.org/en/research-...

The bills are:
Apartments in all commercial areas in cities
Small-lot starter homes in cities
Office to residential conversions in cities
Strong limits on protest petitions
Single-stair
Expanding where factory-built housing can be used
Curbing college-town limits on roommates

Big win for Texans looking for housing. Single-stair reform #SB2835 is a major step forward for legalizing modern apartments that can fit on small lots and above stores.

- Legalizes 6-stories, 4-units/floor, in TX state building code
- Cities that adopt standard amendments to state building code would by-default legalize 6-story single-stair apartments
- Paves way for streamlined adoption by cities

It's easy to lose sight of the big picture, but Rachel provides thorough context on the 2-stair mandate: "Since fires are more common in single-family homes than in new apartments, they say current rules may actually steer people toward less safe housing."

Rachel Cohen Booth @rcobooth.bsky.social · May 8

One of the buzziest ideas in housing reform lately is allowing apartment buildings with just one staircase, instead of two. Though a standard design around the world, American fire safety officials are strongly opposed

I wrote about the debate and research for @vox.com

New Pew brief: Pennsylvania's housing shortage has pushed up costs. Highlights:

Thanks for highlighting this research from @stephenjacobsmith.com and Pew. Lots of reason to think we could improve fire safety by legalizing single-stair because it would bring more of the safest housing type online: sprinklered, modern, multi-family, with self-closing doors & fire-rated walls.

Alex Horowitz @alexhrwtz.bsky.social · Feb 28

Allowing one stair instead of mandating two makes it more likely an elevator would be included because there's more budget and more physical room for it. But we need elevator regulatory reform too so we can get more of them: www.centerforbuilding.org/reports

This is one of the most-discussed housing reforms in state legislatures right now, and here is empirical proof that it’s safe, definitively refuting the only argument being made against single-stair building code reform.

Stephen Jacob Smith @stephenjacobsmith.com · Feb 27

A few findings from this report that I coauthored:
- A stairway in a 4-story bldg costs about $200,000 (corridor not included)
- Zero deaths in 4+-story single-stair buildings in NYC or Seattle attributable to the lack of a second stair
- FDNY has mostly stopped reporting fire deaths to NFIRS
