The Boston triple decker should be the standard home of North America and nobody can tell me otherwise.

Many of the new town houses in Orange County/Irvine area are following this plan.

They do not appeal to me, as I’m not fond of having to scale several flights of stairs, and the individual floors seem quite small, smaller than my first studio apartment.

My first town house was essentially three stories. The garage level, main living level, and a loft. But the main living space was the majority of the square footage so there was little routine need to scale the stairs.

Also the main living/dining/kitchen area shared with the loft offering a nice, high ceiling, and a roomy experience.

While I can certainly appreciate the benefits of the density these provide, the idea of living in several 400-500 sq ft boxes, especially connected with stairs, just doesn’t appeal to me, particularly as I age.

boston triple deckers are not sliced vertically

100% agree. Somerville (city outside of Boston) is 19th on this list of densest cities in the US and I attribute it mostly to 2 and 3-family homes.

Can you explain this for the non-US audience?

I suspect they're referring to this type of buildings https://en.wikipedia.org/wiki/Three-decker_(house)

A little trolling going on in that Wikipedia page. It captions the Cambridge photo as "Three-decker", where locals would call it a triple-decker. It then captions the Worcester photo as "triple-decker", where locals would call it three-decker.

Yep, that's what tons of houses outside of the immediate city center of Boston look like.

Cheap enough for a middle income family to build or purchase themselves, enough apartments for grandparents, parents and children just getting their start in the world. They're great!

The issue with regard to single stair buildings are for things taller than 3 stories. IIRC in America 3 stories is the most common limit by far, and in Canada it's even worse with most regulations having 2 stories as the limit for a single stair complex.
Re:The case to legalize single-stair multifamily housing by pomian on Thursday January 18, 2024 @01:04PM (#39045145)
We need two exits in Canada. Because a snow drift can easily block one exit. That's why there are exits on each side of a structure, not two, on the same side.
Re:The case to legalize single-stair multifamily housing by alexb_ on Thursday January 18, 2024 @01:23PM (#39045471)
Two exits do not require two stairwells - in any case, this is a very weak argument for denying people the ability to buy housing. Especially in Canada, where there is an absurdly large housing crisis due to an extremely small supply.

There was a so-so movie based on this one exit theme once. Forget where it was set.
Re:The case to legalize single-stair multifamily housing by bluGill on Thursday January 18, 2024 @01:11PM (#39045263)
It is generally understood that at 4 floors you need an elevator which is expensive. This is partially the ADA (which doesn't say this from what I can tell, but is generally understood to suggest it), and partially 4 floor is enough stairs few people would agree to walk up them.
Re:The case to legalize single-stair multifamily housing by mjmahone17 on Thursday January 18, 2024 @02:34PM (#39046491)
Which ties into a second problem: the US especially requires elevators to be too large, which limits how many are built because they take up so much square footage, which drives up the cost to install.

In Spain and France you’ll find single staircase, 4 story buildings that have one meter-by-meter sized elevator. Often even as retrofits in older buildings! In NY you’ll find these too, but they’re only in pre-war (1930s and older) buildings. It would make many apartments much more accessible and desirable to live in if we could drive down the cost of elevator installations for smaller buildings.

The word you’re looking for is “cheaper,” not “accessible.” Those 1x1m elevators certainly aren’t accessible for wheelchair users. ADA requirements require the following minimum dimensions for an elevator:

“The width of the elevator car is a minimum of 80 inches (2030 mm). The depth of the elevator car measured from the back wall to the elevator door is a minimum of 54 inches (1370 mm). The depth of the elevator car measured from the back wall to the control panel is a minimum of 51 inches (1291 mm).”

Re:The case to legalize single-stair multifamily housing by mjmahone17 on Thursday January 18, 2024 @07:37PM (#39050096)
More accessible. People with walkers can access the apartment, as can people in smaller wheelchairs, if there is a small elevator. In NYC plenty of older people live in pre-war buildings with tiny elevators. Few live in third floor walk up apartments.

My point is exactly that the ADA, in this case, lets the perfect (fully accessible elevator) result in worse outcomes (brand new apartments in 3-5 story buildings require walking up stairs). This is especially harmful in cities where many homes are on small, 12-20 ft wide lots.

As an example I know people who had to move out of their home when they tore their ACL, whereas with a small elevator they would not need to. To be clear I think we need many many more ADA-accessible apartments, but wherever you are allowed to not have an elevator at all, you should also be allowed to have a small 1-2 person elevator in addition to the stairs.

Boston and immediate environs is still pretty expensive but, at least historically, these sort of multi-unit houses tended to be in less expensive neighborhoods (many of which are now pretty expensive).

The triple-decker three family is great in that there are windows on four sides and stairs in front and back.

There are also double triple-deckers (six units)- the stairs are shared by two triple-deckers sharing a common wall. Most of these are side by side, but in Worcester, there are also front / back ones like this (134 Elm St.):

or with turrets:

The stairs are definitely shared in the side-by-side ones, not sure how it works in these.

So I used to rent in a 10-unit five story brick and wood building with front and back stairs, so I question a bit that the two stair requirement is such a big deal. This building had a central open area, and an old (broken) cage style elevator. Something like this:
