Knoxville approved building code language to allow single-stair buildings up to six stories. Formally takes effect on Jan. 1, 2025. Boom – first US jurisdiction to get to the finish law since @holz-bau.bsky.social and I started making a fuss about this www.centerforbuilding.org/singlestair-...

We need to allow our urban 'single family' neighbourhoods to evolve.
Our vision: Accessible, zero emission, bright, social, bike oriented, #singlestair homes - allowed on individual residential lots - everywhere.

When cities have upzoned, we see more studio, one and two bedroom apartments, but very little development of family-sized units (3 or 4 bedrooms.)
Advocates say single stair reform could help change that, and allow more families with kids to stay in cities if they want

Minnesota has released it's #SingleStair report
www.dli.mn.gov/sites/defaul...
129 pages of fire safety modelling, but my takeaway:
1. Well maintained sprinklers are important
2. Number of stairs isn't important
3. Hallways are the problem (and current code allows for crazy long hallways)

After TO Council passed a motion indicating the City was open to Alternative Solution Proposals for a single stair in apts up to 4 storeys, I applied for a single stair in a 3 storey Part 9 6plex.
I’m told it’s the first one, so it’s a test case. Here’s how it’s going.
