Basement Stairs (Canada, ON code?)
 
Hi, i am new here.

I have completed a fair amount of DIY, however as i have now moved to Canada (from the UK) i have questions over "code" and legal stuff...

So the house i should have in about 2 weeks has a basement (60 years old) so the basement floor to roof is about 71 inches, very low (as old), the stairs in there at the moment are way to short meaning a very large drop to each step and the steps are also short.

I have enclosed a picture, i plan to make a set of steps with 1 at an angle and the lower on at a right angle (90o) allow for more depth on the steps and a better height.

I understand the rule is 7/10, however i can only get this with a 8inch height.... is there any code about this in ON, Canada with regards basement stairs?

After all you cant go moving the basement height or entry points....

Input please... :thumbsup:

Many Thanks
Ashley

Adjust your image size so it does not make the forum scroll sideways.

If you have room make your platform higher and add another step or two or what ever you need to be in code. The main thing here is to be sure you have 10 inches of tread at 12 inches from your rail at the ascension line, glide path or walk line, which ever you want to call it. The codes in your area may be different from here.

It is very difficult to read your thread being this wide, please edit and downsize your picture, if you don't have a picture program to downsize your photos here is a free program that is a really good one and easy to use to downsize photos.

The orginal stairs from new arnt to code, why do the new ones if its replacing old, it may not be possible due to the limits of space, what happends if stairs cant be fitted (due to code sizing), does that mean the basement cant have stairs as "to code" sizes wont fit (making the whole basement redundant)?

Please explain:
"12 inches from your rail at the ascension line"

Don't forget about the head room. As you move the steps forward the head room gets less.

I had noticed this, again this is all governed already, i cant change the upper floor plan (it has stairs above it), this was the reason for the question, there is no way "to code" stairs are going to fit in the hole the house was built with (which is 60 years old i think), so what happends, do i do as i would in the UK.

Make something as close to code as possible allowing alterations for safety over design (so steps finish as fast as possible to stop your head getting hit over making the step flat area (10 inches) to code meaning there an inch shorter to stop you hitting your head)?

Many Thanks
Ashley

The ascension line is the distance from the hand rail where your feet will land on the treads as you go up and down the stairs. When you make a turn, or winder tread, the tread needs to be 10 inches wide at 12 inches away from the hand rail. If the tread is too narrow at this point there is a good chance someone will fall.

I wish I had the answer for you about building out of code but I don't because I have no idea what your code enforcement folks will say about your situation, I would ask them, that way you are safe.

Ashley , welcome to the neighborhood, I'm in Waterloo. We have some strange regulations here which may require code if you replace the stairs in entirety, not sure if you can bypass them if you simply modify the stairs. Cambridge will have its own inspectors so call city hall first. Headroom under the beam is another scenario. This is the only province where I have seen heat ducting run under a main beam as well, apparently that passes. If you had a home inspection done either privately or through your mortgage company they should have noted the issue. You should be able to Google the ON code for stairs.

Ive tried to look for the codes for building and cant find anything (or find alods of stuff frmo USA talking about them).

Do you have any links i can see without calling anyone out.

Will they charge for comming out or do they talk over the counter about this (the UK they charge for everything).

Many Thanks
Ashley

If you leave the existing alone then they are grandfathered in. Once you change them you have to meet current code. It could mean major structural changes but they need to meet code.

Sometimes it is not cost effective to change stairs.

I found a reference/case re basement stairs and the Ontario Building Code that may provide some help.

I am unable to find details of the Ontario Building Code online. Perhaps someone else has a link for same????
