There are healthy limits to free advice, suggest you contact a company like Savaria to discuss.

This building has a LULA small elevator, the report you screenshotted is referring to stretcher-size requirements that are not applicable when the code exception for “limited-use/limited-application” elevators is used.

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-...

Modular, mass timber, and single-stair

This workforce housing project in Montana maxes out the current IBC code limitations on single housing with a 10,000 sf floor plate and 8-bed units that each feature shared living, kitchen, and laundry.

This comparison shows the price of putting an internal garage on a rowhouse

Both of these rowhomes are ~16' wide

Left: 2BR+Den/3BA
Right: 4BR/3.5BA

So the cost is losing TWO bedroom.

Visited two of my favourite Point Access Blocks (single stair apartment buildings) in Berlin… E3 on Esmarchstrasse in Prenzlauerberg (encapsulated mass timber, noncombustible exterior stair) and Walden 48 co-op housing project nearby in exposed mass timber and treated wood cladding.

Why are single-stair buildings actually SAFER than two stair buildings in some circumstances?

It seems counter intuitive… obviously, more redundancy is better, right?

Important TOMORROW:

The LA City Council is going to vote on whether to legalize single stair buildings. Opponents have launched a disinformation campaign, and we need people to give public comment in support.

Will you be joining me tomorrow at 10am in City Hall?

Design study comparing single-stair vs multiple stair egress on a small 5,500 SF lot in Denver:

(L) double-loaded corridor
•71% efficiency
•(4) units

(R) single-stair
•87% efficiency
•(4) dual-aspect units

We must work within the firefighting capabilities that exist here today, and hence focus on technical conditions to achieve a better level of safety/lower risk through building systems and design.

Sweden and Germany’s codes are premised upon corridor separation of the exit where ladder rescue cannot be accomodated. Since ladder rescue is not practical in North America above 3 storeys (trees, overhead utilities, access routes) - the basis of SES/PAB >3/4 storeys is that it must have corridors.

Week 2

On a tiny corner lot in Boston, Condor Street Housing shows how much a single stair can do. A small elevator makes every unit barrier-free, linked by a short corridor to meet code. Even on one of the tightest sites, the plan delivers safe and accessible homes.
