That is an interesting question. Very aggressive framing you chose Would you believe me if I told you that nearly all of fire deaths in the State of Connecticut occurred in detached homes? Detached homes are only ~60% of CT's building stock but are ~80-90% of the total fire annual deaths
Perhaps you could answer the question? So 65% of Connecticut residences are single family (attached or detached). 10% are multi residential special purpose facilities. Of the 65%, the median age of residence is significantly older than the 5-49 family units.
In 2024 there were 23 residential fire fatalities in Connecticut from with 19 being within a 1 and 2 family residential facility from a total of 1.53 million facilities (US Fire Administration). (Not statistically significant). So I’m not sure what your point is.
You posited that it was the ratio of occupants to stairs that matters most and that SFH have adequate fire protection and yet the data tells the opposite story that SFH are statistically more dangerous to live in from a fire safety standpoint. bsky.app/profile/qm61...
Add in single stair apartment buildings have a higher ratio of stairs to occupants than normal US double loaded corridor apartment buildings and by your figuring that makes them safer
Look - I didn't start out convinced here either. But I followed the data and it clearly shows these buildings are safe, they are built across the globe, they have layered fire safety measures that aren't found in SFH/other small detached homes, and they're super pleasant to live in
So is that the 3 units to one stair plan?
Yes, I would prefer to live in a single stair apartment building over either a double stair apartment building or a detached home. What are you getting at?
I’m trying to determine at what point you may feel that arrangement was inadequate. For a 2 level site each stair related component would be legal. But at 10 levels it would not be. At 10 levels you would have 30 family units emergently exiting via a single stairwell. How many levels do you propose
The short answer is it does not matter because you have lots of other safety features built in. Fire in one of the units? Alarms start going off, entry doors auto shut containing the fire, fire walls prevent its spreading for at least 2 hours, fire department arrives and uses standpipe to put it out
Fire spread to hallway? Automated fire suppression system kicks in to douse the fire. Stairwell is built to prevent it from catching fire, not made of wood. Door gets jammed? Some regs require a negative pressure environment to vent hallway smoke up and out to keep stairway clear
Can I ask which one of the two plans do you prefer ?
I would personally move into in a family sized 3-bedroom single stair apartment with lots of windows on all sides in a heartbeat if it were legal to build in this country
Unfortunately you can’t reach that conclusion from 23 residential fires in 1.53 million homes. The data actually says that there is no difference. Lower density housing with a font and back door appears to be equally safe as multiple exits from higher density.
Also, you don’t get to demand that people “answer” you pointed, rhetorical questions. I’ll respond to you however I wish. If you don’t like the responses, ask better questions.
The thing is your opinions of what is safe are extremely updated. Most of Europe does not have the two stair rule, and they don’t have millions dying in fires every year. Hardly death traps. And a huge portion of the US middle housing stock is pre-2-stair-rule. Also not killing millions here.
