Code Changes- part 9, Housing & Small Buildings Stair run has changed Minimum run for private stairs was 210 mm ( 8 ¼ inches) in 2010 NBC, now changed to 255 mm (10 inches) in 2015 NBC. 2015 Note: The increased minimum run of the stairs will affect the size of the stairwell opening required to maintain the minimum headroom requirement of 6’4 ¾ “. As well, a 2 x 12 may be required for a stair stringer as it is necessary to maintain a minimum 3 ½ inch uncut portion of the stringer.

Code Changes- part 9, Housing & Small Buildings Previous Code- Referred to “Angled” treads New Code- Refers to “Tapered” treads 2010 2015 Note: The increased minimum run of the stairs will affect the size of the stairwell opening required to maintain the minimum headroom requirement of 6’4 ¾ “.
