Sorry for the late reply. I have tried to reply to your question multiple times and in the end, it becomes a very very long, complicated answer. Sooooo...... In short I will simply say: I didn't ignore this question, but it's simply not a question that I can answer by this means without confusion. If in the future I have questions and answers video, I may tackle this in such platform.

I love all your videos. They are so well done! There was one thing at 15:10 about landings that I went back to the code to verify. The code says that the minimum depth of the landing is equal to the width of the stairway or 48", whichever is LESS (1011.6). You said it was whichever is greater. I only know this after digging through the code for a commercial project and the landing min came up.

Hey, I would like to thank you for basically tutoring me. I will be taking the IBC test to take to become a general contractor and these videos are helping me to understand work the code mean and why they were written as well as justified. I hope you did all 35 chapters because between me reading the 2015 codes books and the videos you have so I can understand what they want is a blessing for me. I know I will get my GC license now

Thank you for your videos. They are of great benefit. After viewing your Stair ADA and IBC requirements video. I wanted to point out that "nosing" is a defined term in both the IBC and IRC, "The leading edge of treads of stairs and of landings at the top of stairway flights". Every tread and landing at the top of a flight has a leading edge or NOSING regardless of the projection. Nosing projection is limited in both the IBC and ADA as you state however you cannot slope the riser even close to 30 degrees if it is in one plane as you illustrate because you will exceed the limit of the nosing projection. The face of the riser would have to consist of multiple planes for any of them to approach the 30 degree maximum allowed. Nosing is not defined in the 2010 ADA. As such the term would have the the meaning as defined in the referenced standard. The IBC is a standard referenced of the 2010 ADA Standard. The illustration of the sloped riser you show is similar to that in the 2010 ADA, the Access Boards Guideline, and the A117.1 Standard. It is my understanding that the illustrations in these documents are editorial in nature and not enforceable. In any case the drawing causes great confusion as it conflicts with the text of the each of the regulations noted above. It would be good to point out the issue in your video. Thanks again for the service you are providing.

It's refreshing to know there are other people out there nerding out over the code (hehe), but that is AWESOME. What you are mentioning is very interesting. You are correct, if a riser is 7" in height, having a 30-degree slope would exceed the projection allowance, but technically speaking, the 30 degrees is a maximum. Is this what you are trying to say? If so.... AGREED! Don't shoot the messenger, it is written in the code, but it could've been written a bit better, true. I wonder if anyone knows a scenario where 30-degrees is actually doable as per the illustrations provided in the standard codes. Probably one of the most interesting technical comments received here at archicorner! THANKS!

@@archicornerI don't know of any stair with single plane risers sloped at 30-degrees angle, however I do know of conditions where the riser is actually sloped enough to exceed the allowed nosing projection which is the point I think worthy of inclusion in your video. In the meantime we are working on needed changes to the illustrations and text of the A117.1 standard in the current development cycle now underway.

Thank you for the reply JJ. In reply to your comment; Yes and No: Yes, the video does show the extension requirements. Starting at minute 7:38 you will see it. However, No, the video does not show 24 inch extension at the bottom. The 24 inch extension is a California requirement, not an ADA requirement. ADA 505.10.3 is different than CBC 505.10.3. What state are you in? If you are not in California, it would be of interest to find out what other state has this same requirement. Please reply if you could please. Thank you for leaving a comment!

Other than that, the CASP Inspector was saying that I have to also install detectable warnings in front of all the exit doors that lead onto the pavement but not onto the driveway and they are not along accessible path of traveI. I have no luck looking for code regarding this. Your reply would be much appreciated! Jim

In the section 1011.6 - 1/2 required clear width of the total dimension for the landing that means the landing never can be 48 inches bcs in that direction we have at least 32 for the door plus 32 clearance = 64 min for the landing ?

If there is a door in a stair landing, you are correct, the building code requires the stair landing + the door allowance per IBC 1011.6. and as you noted, this will likely need a landing that is more than 48 inches depending on the door layout. HOWEVER, not all stair landings have doors. For example, in most switchback stairs, the intermediate landing does not have a door.

Hi my friend. I have a question please. You mentioned that we calculate the stair width based on the occupant load of one story.. but what if I have multistory building and each story has its own occupant load or occupant group ( like in mix-used building), which floor I shall consider to calculate my stairs width? Is it the one with the highest occupant load?
@archicorner
2 жыл бұрын
Yes and no. If you have multiple stories, you calculate the occupants of each story SEPARATELY. Thereafter, each story must have the width of the stairs provided ALL THE WAY DOWN. For example: if the 5th floor required 48" in width but the 4th floor required 60" in width, in theory, you could have 48" wide stairs from the 5th floor down to the 4th floor, but once you got the 4th floor, you would need to have 60" wide stairs from the 4th floor, all the way down. I hope that helps. Please consider being my patreon or buying me a coffee (no pressure at all)..... :). patreon.com/archicorner buymeacoffee.com/archicorner

Various states have "additional" requirements for accessibility beyond the ADA. Here in california, we do have additional requirements that require an added level extension at the bottom. Therefore, the answer would be; it depends on your state/county/city and what they require.

Not sure what you are referring to. A flight of stairs can have an intermediate landing as shown in the video at around time frame 3:40. I am not sure if that is what you mean. In general obstructions are not allowed to impeded into landings, not even the stairs themselves. Sorry if this is not what you mean in your question.
@jeffparry2426
Ай бұрын
The way I think of it is that stairs have to have the same rise and run at the walk- line and, this allowes winders, the only way to change the rise or run or both is with a landing. A landing has to be 36x36 (minimum) with a change slope not greater than 1/4" per foot. If you put a stair in the landing area you can no longer call it a landing and it would exceed the allowed tolerances of rise and run in a flight of stairs.
