3:33 Not accurate, you calculated the "shortest possible ramp length for a 30" rise, not the "longest possible ramp length for the ADA rules to still apply." In doing so, there seems to be a bit of confusion caused. First, it is not that you "cannot have a 50' to 100' long ramp for a 30"(inch) rise" it is that if your "ramp" is 50' to 100' in length, the ADA "does not consider such a pathway as a ramp as it is so long for such a short rise, it is not steep enough for the ADA to consider it an obstacle which is rises to the difficulty that neccesitates the "Ramp rules" be applied. For example, in many forests, prairies, etc. raised wooden pathways are often constructed to serve as ADA compliant paths for people to use to enjoy the surrounding nature. These pathways, inevitably shift due to their very nature of being a low impact on nature as possible (light footings, shallow footings, not the strongest foundations) combined with the "nature" of nature to shift, change, etc. especially in the North where freeze/thaw cycles wreak havoc on such structures requiring footings as deep as 5 feet for a stable walkway. This shifting, or even the inclined design of a path to overcome the natural rise in the land it traverses, can result in on end of a section of pathway to be several inches or even feet higher than the other end, especially if the section is over 100' long. To avoid the cost and distraction from view that complying with ADA "ramp rules," these pathways are designed to have a maximum rise of 1:20 thus avoiding the need to comply with the ADA ramp rules. ADA ramp rules apply only to sloping paths that are over 1:20 but less than 1:12, so a 1:19.999... path would be a ramp that needs to comply with these rules. Such a 1:19.999 ramp which traverses a rise of 30 inches would have a slope or rise:run of 30 inches (rise) : 599.99 inches (run) [ 19.999 inches ramp length per 1 inch of ramp height means a 30 inch ramp rise would have a 19.9999*30 inch length or 599.999 inches or just short of 50 feet. Such a ramp is "allowed" but not because the ADA says it is allowed, but because the ADA says such a path is considered a ramp by their applicable definition and thus the ramp rules must be applied. Again, it is not so much what is and is not allowed regarding run lengths that are very long, but what can and is considered a "ramp" per definiion, as once it meets the definition then you have to comply with all those ramp rules. Also, you likely won't find a ramp that is 50' long or longer as they are not generally needed or wanted, either because the ADA rules require flat landings as a place to rest every so often or because such long lengths cannot physically fit on the smaller business lots where these ramps often are needed as retrofits or because at that length, the rise is more likely to be so shallow, the path is not a ramp by definition or some other ADA compliant device, structure, etc. would be a better solution. Your calculation was for the "shortest" possible length of a ramp at 30 inches of rise; A ramp any shorter than 30 feet over a rise of 30" is too steep to comply with ADA ramp rules in general. Again, you can have a ramp that rises 30" be 'longer than" 30 feet. For example a ramp that is 48 feet long and rises 30 inches is a "ramp" per this ADA definition as the rise:run is 30":(40feet*12inches/ft) or 30":480" or 1:16 which is smack in the middle of the 1:12 to 1:20 you discuss at 1:30 in your video. Conversely, if a path is 28 feet long and rises 30 inches would have a rise:run of 30:336/(12*28) or 1:11.2, a slope steeper then the max of 1:12; for rise:run, the "run" number has to be between 12 (steepest slope) and 20 (flattest slope) as if the "rise" number is lower than 12, it is generally too steep to be allowed by the ADA, while if the number is greater than 20, the path is flat enough that it is not considered steep enough to have the ramp rules apply to it.
Very Good Information. Question: For the ADA Cross Slope, you use the ratio "1 inch to 48 inches" for ensuring that the Cross Slope is 2%. But "1 inch to 48 inches" ratio is actually 2.08%. How should the '.08' be treated? Should 2.08% be rounded to 2.1% OR is the .08 dropped to get just the 2%? Thank you for your time.
Hello, thanks for these videos, they are really informative. I like the graphics and format you use for the presentation, do you have these videos in paper form, if yes, how can I get a copy?
great video! a question about the ramp, if we have the ramp at 36" (which is the min) and also need to add the edge protection which takes up 12"- do we additionally add it after having the 36"?
@archicorner, please also make video on Emergency egress door locking requirements and restrictions. Can Egress doors have lock on it or not? Interface requirements of access control mechanism.
Your maximum slope allowance is 1:12. Think of it as 1 foot horizontal per 1 inch vertical. If you only have 20ft of length, using the maximum allowed slope for a ramp, you could only go up 20 inches. Therefore 20 feet is not enough run for a ramp. Not to mention you need top landings and bottom landings.
Fall protection from heights is a chapter 10 requirement (Building Code). Handrails are normally an accessibility requirement (ADA/Accessibility). Normally, platforms less than 30 inches in height do not require guard rails. This takes me to another quick subject. Don’t confuse guard rails with hand rails.
There is no "finish" requirement. The typical requirement for floors in general to be "stable, firm and slip resistant." Steel and aluminum are often stable and firm, but a finish that prevents slipping would be required.
Great Video! Recently visited a cousin that needs a ramp. She was told it couldn’t be installed on her mobile home because it was to high. I don’t find any limits on height as long as it meets the slope and other requirements. Is there an organization that can help her get a ramp?
As long as you have the room for a ramp and landings and also, as long as you do not interfere with any easements or set backs, then there “should not” be a problem with it. As for organizations that may help, I am assuming you are asking for monetary help. I am unsure if that is available. Each county/state may have varying options (if available).
Ada is ridiculous- change the whole business front door space that makes money with tables and chairs which are busy all day... just for the 0.0003% we need to lose out on business- so stupid. They want to come in- that's fine. We have a portable ramp. Nope- not good enough- destroy your income for this

You cannot have a continual ramp, but you can connect many and chain them, having "lamdings."

Illustrated and explained ADA Ch 405 well. Thank you
Super helpful video, thank you!
You're so welcome!
Thank you. I'm a lic. P.t. in NM & I used this as a reference in a current case situation- very helpful
Glad it was helpful!
I learnt all I needed to know. Thank you!
very good video thank you
You always do such a great job in presenting it as well as explaining it. Thank you!!!
Thanks 😊
Very well explained. Thank you
No problem, glad you thought so.
Are FHA/ANSI/HUD requirements different? Don’t they state anything over 5% requires handrail’s?
Thank you so much for your services your explanation was outstanding it has helped me tremendously
You are so welcome!
please do one video osha standards on this
Nicely done dude thank you
You are welcome!
Awesome thorough explanation, my man thank you
My pleasure!
Please can you throw more light on draftstopping, firestopping & fireblocking. Thank you, really appreciate your teachings.
That is a good subject. I will keep it in mind.

Speaking form my locally acquired experience, I am not experienced with the entire USA, 2% is what is required. The decimals are not even considered.
Thank you.@@archicorner
DO NOT GO OVER 2% CROSS SLOPE YOU MIGHT GET THE WRONG INSPECTOR AND WILL MAKE YOU REDO THE WORK. I PERSONALLY ALWAYS STAY AT 1.5% TO BE SAFE.
Could you address doors preceded or followed by ramps and landing requirements for such cases?
Thanks for the video. You know what you are talking about.
Thanks for watching!

can i use 2x4s for temporary ramp handrail ? what spec do i look for answer
great video! a question about the ramp, if we have the ramp at 36" (which is the min) and also need to add the edge protection which takes up 12"- do we additionally add it after having the 36"?
It should be 36" clear.

good topic, I will add it to the list.
25 inch step. How long should my ramp be?
Is there different requirements for a person with a powered wheelchair?
For California, do we use cbc or ADAS or both?
Great job thanks
Thank you too!
for straight ramp, required bottom landing to be 72" min
Is that ADA or California code?
@@archicorner yes cbc 2020 figure 11B-405.7
Ok, so that’s the reason why. This video is for ADA. Not California Code. CBC is different than ADA.

Great video..👍
Thanks 👍
How to make ramp for home. 30*45 feet.
So i have a 30 inch rise and 20ft of length can that be built as one straight ramp? Or will the slope be to much?
Your maximum slope allowance is 1:12. Think of it as 1 foot horizontal per 1 inch vertical. If you only have 20ft of length, using the maximum allowed slope for a ramp, you could only go up 20 inches. Therefore 20 feet is not enough run for a ramp.

Does a platform under 30" height above grade require a handrail, or just the ramp leading to it?
Fall protection from heights is a chapter 10 requirement (Building Code). Handrails are normally an accessibility requirement (ADA/Accessibility).
Normally, platforms less than 30 inches in height do not require guard rails.
This takes me to another quick subject. Don’t confuse guard rails with hand rails.
So....does a platform require a handrail if it's under 30" tall and is reached via a ramp with a handrail?
what is the finish required for the steel or aluminum ramps
There is no "finish" requirement. The typical requirement for floors in general to be "stable, firm and slip resistant." Steel and aluminum are often stable and firm, but a finish that prevents slipping would be required.
Thqnks
Thank you!!!
You're welcome!
Do I need to permit an Ada ramp in California?
In California you need a permit for just about everything.
Can you sketch me a design? Floor to the bottom of the door has 18 inches
Can you design me a skillet ramp for my property 30 feet wide 120 feet long slop 5%
Not sure what a “skillet” ramp is. 🤔
Great Video! Recently visited a cousin that needs a ramp. She was told it couldn’t be installed on her mobile home because it was to high. I don’t find any limits on height as long as it meets the slope and other requirements. Is there an organization that can help her get a ramp?
As long as you have the room for a ramp and landings and also, as long as you do not interfere with any easements or set backs, then there “should not” be a problem with it.
As for organizations that may help, I am assuming you are asking for monetary help. I am unsure if that is available. Each county/state may have varying options (if available).
Thank you for taking the time to answer. Best wishes to you.
Spanish version???
Hola me gusta 👍🏻.

Why don't you do 8% that the professors told me?
1:12 is 8.33. That is the "maximum" 8% is totally doable as a ramp.
Ada is ridiculous- change the whole business front door space that makes money with tables and chairs which are busy all day... just for the 0.0003% we need to lose out on business- so stupid. They want to come in- that's fine. We have a portable ramp. Nope- not good enough- destroy your income for this
