9.8.3 (October 16, 1996)
**BRANCH OPINION **
RE: STAIRS FOR TOWNHOUSES
Proposed stairs for a townhouse project. Each flight of stair connecting two floors is indicated to comprise a straight run, a winder and a curved run, all meeting the requirements of Section 9.8 of the 1990 Ontario Building Code (OBC).
Section 9.8 of the OBC sets out the requirements for regular stairs (straight runs) under Subsections 9.8.3 and 9.8.4., for curved stairs under Articles 9.8.5.1. and 9.8.5.2, and for winders under Article 9.8.5.3. However, this section does not explicitly restrict how these three types of stairs can be combined. In consequence, it is the opinion of this Branch that your proposed stair arrangement meets the intent of Section 9.8 of the OBC.

Doing some grow-op inspections, Mario?
Does anyone have Article 3.4.6.8 from Alberta’s Building Code 2006 Volume 2?
Brian,
That’s funny!
What’s also funny is I find myself inspecting while I’m on vacation! Is it just me or does everyone inspect while on vacation?
Marcel,
All I can say is, thank God for building codes!!
Here is something I didn’t know!!
http://www.nbnnews.com/NBN/issues/2005-05-16/International/index.html
[size=4]ICC partners with Mexico to develop building safety codes[/size]
Under an MOU signed by CEO James Lee Witt and the Mexican National Commission of Housing Development, ICC will provide technical assistance to the Mexican government to develop a residential building code based on the I-Codes.
“The Mexican government has a long-term plan to update its construction standards to include the safest techniques, materials and technologies,” Witt said. “The I-Codes, already enforced in thousands of U.S. jurisdictions, will be the basis for housing construction in Mexico. The codes will provide Mexico’s residents with safe, affordable and comfortable housing.” Click here to read more.
Brian,
Thanks for bringing that up! The original pic didn’t show it but there is a landing therefore the winders are 90 degrees.
Bill,
Are they the only province that doesn’t follow the NBC?
That reminds me when I built my first house back in the 70’s, the municipality didn’t have any and that was in Ontario. It was a free for all…the house is still standing.
It is my understanding that the NBC is the base and can only be improved upon…

Good info, thanks Claude!
Thanks.
I went there and found the '06 Alberta Code I’ve been working on. And purchased it. Wow! $250
Thanks, guys, for all your help. InterNACHI stair checklist (United States and Canada) coming soon. And credit goes to you all.
This stair does not meet the code. There can only be three thirty degree winders or two 45 degree winders in one flight of stairs.
These stairs are not safe and should be reported as such
If the house has been given an Occupancy Permit, the issue of the stairs is moot because the town issued the permit. So the best advice might be suggest installation of a hand rail.

You should infract the stairs and advise the owner to ask the authority having jurisdiction why they have passed the stairs when they are not constructed to the building code requirements.
This is what I do when I come accross these items.
Vern,
But there is only three thirty degree winders…
J’comprends pas!
The issue is how the local AHJ (authority having jurisdiction) measures and determines the size and safety on the “questionable” winder area of the stair.
We as home inspectors are not there to supercede their “authority”; however, as a home inspector if you are aware of a code “infraction” than it is best to cover your a$$ by noting the condition in the inspection report as a “safety” concern.
I always thought tread was the actual physical surface area of a step and the run is the linear distance from nose to rise of the next step.
Marcel
How old is the house in question?
[RIGHT] [/RIGHT]
Run equals Tread minus nosing.
Tread equals run plus nosing.
