Thanks for summing up the last five weeks of the college course I’m taking
:) :)
What course are you taking? Which school?
@@antoniocortez1326 what ever course and school it is. They’re both a waste of time and money and useless. Screw college
LOVE LOVE LOVE the detailed information about code! Please more of these for all the things! Electrical, plumbing, insulation, and more!
Agreed!
Its amazing how often i have seen Stair builds that are not code built for people. This is great reminder to check and read your code book
Super helpful as I am building basement stairs and finishing our basement. Really appreciate this video!
Can you make a video on stair railing construction? Not necessarily on code requirements, but fastening methods for things like base shoe and fillet, spindles, etc.
It's not the baby's head, but the body that can fall trough feet first. Body will go trough and the head gets stuck and baby is left hanging. Very good video, very instructive. Thanks for sharing. God Speed and God bless. ;-) keep them coming.
Yepp, i like open best. You solve this easy by putting a board under the step that gives both strength to the step, opens for the foot and makes the hole smaller.
I've seen it several places that the calculation for comfortable stairs is Rise" + Run" = 18" (You mention 17" in the video). That's not to say you're wrong. Your right in there but my research shows the following. It was either the IRC or IBC that recommended 7.5" rise over 10.5" run. I've also seen another carpentry method for comfortable stairs that says (2 x Rise") + Run" = 25". If you were to graph out these two methods on a sheet of paper they actually intersect at a prime comfort ratio of 7" Rise over 11" Run. 7" + 11" = 18" and (2 x 7") + 11" = 25". Just some food for thought.
Hand rail height = 34"-38" from top edge of nosings vertically to top of hand rail,and all hand rails must return to wall at top and bottom.
Just saved me a ton of work and a failed Inspection with the overall length at 147. Thank you sir!
Whenever your videos pop up I make myself watch them it’s like doing homework when I want to watch cartoons but you can’t beat good free information
B Nonya )l
I make a lot of outdoor stairs ( decks, balconies), i try to aim for 6" max (5"ideal) rise per step with an 11"+ tread. Very comfortable for any age to use.
Yeah man. I've been building like 6 12 temp stairs around our work sites and you can cruise up and down them!
For winders, the 2018 ICC R311.7.5.2 states tread depth shall not be less than 10” within walkline and not less than 6” at any point within the clear width. The 4” and 9” is a North Carolina code change. Great video explaining the code for stairs. Very helpful for builders and inspectors alike!
Hey y’all, really loving your videos! If you find yourselves in Asheville, we should grab a beer and chat RUclips and building stuff.
Hey thanks 👍 would love to do it… I actually come up to Asheville all the time! Shoot me your email address so we can exchange info
And wow! I just checked out some videos on your channel… You’ve got it going on!
Perkins Builder Brothers thanks! Just shot you an email.
helllo from 2021
Was this real life? Lol
Good information. We built 5 sets of stairs for our condo. Our carpenter friend did helped us lay out the stringers. One of the homeowners attached the 2x6s for the treads using some leftover trex screws instead of using decking screws. The inspector called us out on them but eventually let it slide. Otherwise we followed the code. If a hurricane comes the building may be gone but the 5 staircases will still be standing with all the bracing and lag screws required to anchor them!!!
That's assuming the ICC is applicable in a person's region - in Canada we use our own national building code as a standard. From that, municipalities adopt or develop their own codes, and is what the inspector for that area will want to see when it's finished. Stair location can play a factor in different regions too, ie: indoor vs deck stairs. Some codes call for an 11" tread for outside stairs while indoor is 10". Some call for 10" treads in both cases. You covered the basics for stair building, but people should really consult LOCAL code requirements before building them. If they're doing it professionally, as a contractor or a handyman, then they should definitely spend the $ on a code book that's applicable for their region. A certified journeyman should already have one from school to begin with...
38 year Carpenter here, I allow absolutely no variance building my staircases, there's nothing worse and there's no excuse! The only problem with extensive knowledge in building staircases is, you're the one that always builds them! 😳 As always, good video!
I really appreciated your video. I've been trimming out stairs since the late 90s. Thank you for pointing out the carpet exception to the rise code. I immediately looked it up and it says the same in my Michigan code book. I never noticed that before and I'm not sure how many are aware of that. Seems like every inspector has their own version of how they treat carpet and you have to second guess them. Now I can show them the code book.
Also, here in Michigan there is no exception for the top and bottom rise being greater than 8-1/4". I was quit surprised when you said that where you are at, you can be 3/4" off. That is a huge trip hazard especially at the top step, the worst place to have a misstep, no pun intended. That doesn't make sense to me at all. I personally know of a case where an individual fell down their stairs at home and it ended up being fatal. The top of the stairs is where you definitely do not want to trip at, especially going down the stairs.
Another point, I always heard that a rise and tread should ideally equal 18", not 17". And an even better way to calculate it is to double the rise and add one tread equaling 25". It's even better they say, not sure if its code though.
Again in Michigan the least you can have on winders is a 6" tread depth at the narrowest part, not 4". At one time it probably was though
Finally, I noticed you didn't get into the railings much, but I thought I'd mention this too, because its such a huge one here at least. Here you need a continuous rail going up at least one side of the stairs from the first step to the top so a person can maintain a grip on the rail and never have to take it off until they reach the top. That one gets people a lot. For instance, if you have a wall half way up you need to jog the rail around the wall and continue on up to the landing or next floor. The rail can't be in two separate sections.
I realize codes are different though out the country. Just thought I share what I know about Michigan. Thanks again, keep up the good work.
Very very interesting. 😊
New scriber here. Just retired 2 years ago after a long career of 46+ years in the construction field. Great breakdown of the codes, one step at a time. ya gotta love it :{I>
As a general contractor who started out in the flooring industry 34 years ago I can tell you that your reading of the code with respect the carpet is not what was intended. Carpets mentioned are free carpet unattached to the substrate, ie throw rugs. In contrast, wall to wall carpet is measured from the top of the backing to the floor. So typical residential carpet will be about 3/8 of an inch, as this measurement includes the tack strip. And yes, a diligent inspector will put a tape from the top of the carpet to the top of the first tread. They have done just that on many of my jobs.
Mine too. The ICC is also only applicable in the US, and if the US is anything like Canada, then code could differ from state to state as well, or city to city even. We have a National building code standard, and from that each municipality develops their own code. In one town the local code might call for 10" treads for all residential applications, while 20 min away in the next town over they could call for 10" treads indoors and 11" treads on all deck stairs. A person should really forget anything he pulled from the ICC, retain the basics from this lesson, and consult LOCAL building code in their area to make sure they don't end up building the damn things twice. Just ask when applying for the permit (which people should be doing). Inspectors are usually more than happy to spend lots of time talking about how they like to see things done...
@@JamesBiggar That is all very true In the us as well. But the ICC is typically adopted wholesale and then Exempted or deviated from on particular items. Such items typically include International Existing Residential Building codes for ADA, or IRC foundation requirements, or any number of other adoptions of a similar type. But such deviations do not typically include stairs, In as much as municipalities rarely find anything unique about their environs or labor force that would require a deviation. Point being that variation from state to state or municipality to municipality are typically put in place on top of the code do as to better facilitate the uniqueness of a particular region. But there is nothing about stairwells in new costruction that would require any such considerations, except for perhaps uniformity with existing structures in inner cities. But the house being displayed was not being built in the Inner City. And besides, he was quoting the IRC incorrectly. His interpretation is simply factually incorrect. But in general I do agree with your sentiment.
it's fun to see how all the intros have grown. Super creative guy Erik!
Max riser height in the 2018 irc code book is 7¾" not 8¼". No allowance for a ¾" variance in the top and bottom riser either. All risers must be within ⅜" of each other . You may have a local or state amendment that allows 8¼". Also minimum tread depth on a winder is 6". This could cause a big headache for somebody. R311.7.5.1 is the code section for riser heights
In our code (MA) we have to be within 3/16” between two stairs but within 3/8” of the whole run.
Has there been an amendment lately for tread depth?
Has the code changed?
What’s the minimum today?
Yes, 7.75" max riser.
Working on building my own house. Thank you for this!!
All the stairs at the end..... beautiful!
Great information and delivered well considering how dry the content happens to be!! Good job Eric!
Nice work! I love your quick and concise videos. Your format is much more enjoyable than other long and drawn out videos that most others employ.
excellent guidance. Best discussion of stair layout on youtube
Great Job, hope all are well in the Family.
There is a lot of codes with stairs. Up our way hand rails have to turn into the walls. That's so when your house is burning the fire hoses don't get caught in them. You can get a good pamphlet from the stair builders association that covers a lot of the codes with pictures to help explain what the code says.
In Maryland a lot of people decks fail due to no solid risers installed. Also if you cut the deck stair sides, you have to use a solid piece of lumber to reinforce the cuts. Also the Minimum dimension for spans applies here.
Learned something new about measurements on stairs, thank you.
Recently-ish, When the Brady bunch home was renovated/altered to actually resemble the home in the show, They had to install plexiglass sides on the stairs to meet code but not be seen, When I was a kid you started a lawn mower with a hunk of rope.
Darn . Now if only I knew the jargon and had a picture of all the stair parts
Lol nice video man
Great Video as always I still cut alot of my own stairs but there's alot of builders here who just order them completely assembled
aha ! problem is solved ! i'll just buy one ! pls make vlogs too brother what else are available to be ordered :) :)
I really appreciate this video! I am planning to build a loft in my garage and learned a lot from this video. Thanks.
Great info!! A lot of people have no clue about codes!!
Knowledge is power thanks been following y'all from Day 1..
Good job on your video. Easy to understand . This video is worth everything for the first point you make about taking into consideration the finish thickness on all the places that get added to later after the framer is long gone. I didn't know the IRC 2018 could be State specific . the one I have doesn't have any state on it and its quite a bit different from yours.
I don't even need to see this vid to like it . Thanks guys
Bro dope af video no cap. Figuring this out as I go and yall are a goldmine of information
I really want to see this house build 😢
Great video! Here in fiji we don't do many wooden stairs, mostly concrete and we don't have a $200 code book either. Good information either way.
Nice work man those radiused returns and rebar pickets real nice touch man !
I like this video, and I agree when they are shorter in length they just "feel" better, but, I would have liked to have seen some additional examples emphasizing the points of the code being explained. Scene changes and topic changes, (perhaps to the point at hand, "nose to nose, head height, landings, etc."), can make a longer video feel just as "comfortable"....Long winded talkie talkie talkie videos can get looonnnng in short order. Thanks for the info!+++
Ive been doing 1/2" for carpet on the last 3 houses for this new builder.... Hopefully the final passes!
matt mag LMAO! You best hope so because that would be a bitch to tear out! 😂
Good info! That Makita cordless saw is my favorite.
Thanks again guys for another great vid. You guys are great at this tooo
This is something the guys should do on every new build for all the new subscribers to see in case they don’t see earlier vids like this
Not sure about codes in Texas but I trip on the first and last steps either going up or leaving because those steps are shorter or higher in height. And it’s completely open. I have an size 9 in shoes and a good chunk of my toe into mid foot goes through the empty risers. I always hated carrying heavy awkward things into the apartment like when I first moved in. Hoping this video explains how many stringers is needed minimally for certain wide a step is. See a lot of videos that builds decking but use like 4 stringers on a (I’m exaggerating) 15 ft wide step.
Great video. I wished he would’ve cover hand rail codes.
There is one exception to Winder stairs. If you ask your contractor to put in a firemens pole. You can have more fun going down. Lol Great Video as always. I didn't even know North Carolina had a code book. I thought it was close enough.... Nail it! Lol
2:00 I keep reading handrail can use 4.5", not 4-1/4”. More I listen, the more differences (e.g. max. riser height) your book seems to suggest. Interesting!
I love your video. Thanks for sharing!
Perkins brothers, any chance you will share your plans on the staircase in this code video? My. Husband has seen it and won’t settle for anything else. He is a wood collector if that tells you anything. Of course he will follow our local codes . Thank you
One of my favorite channels , thanks for sharing
Good information summed up nicely. You guys are the best!
Inside corner tread depth on winders =6" in Michigan.
You the man Eric thank you
Just some advice… I live in a condo,carpeted stairs going into the unit. Prior owners installed doors blocking out heat and old. I closed with a CO approval of this 13 years ago!… now fire dept wants them removed… omg!Your thoughts please
Excellent information!
Great video! One of the worst things to see in a otherwise nice home. Unfortunately one of the last things people consider and then try to fit in at the last minute.
Very good knowledge dudes, keep up the awesome content
Wow 8.25 rise that's a big step. We try to stay 7.25 I MI. And from a fire department stand point 36 inch landing is NOT enough for WHEN we need to bring a cot in.
I enjoy the videos. Don't know a whole lot about carpentry. Would help me if when you are talking about the "nose" (or whatever) if you pointed it out or had overlay/cartoon drawing of it.
Great idea Charles
The nose is the edge of the tread closest to you when you are walking up them. The rounded over part or edge is called a nose.
Should a stringer be cut from 12" or 10" by code?
When I had my little company that was a requirement. Some one came and told me he was a carpenter and wanted work I would give him and area and tell him to work out the stringers for a set of steps. If he could do it I would hire him at carpenter wages.. if not.. well he could get apprentice pay if he wanted work.. that was the 60 - 80's
I am in Canada , where can I buy a code book?
At 2:00 minutes, you mention an exception to the stair width code of 36" (min) if the stairs are not needed for egress. However, I am not sure where this code is written in the IRC. The reason why, we have a non-permitted portion of our house that has a basement stairwell of 35", but there is an egress window less than 10 feet away. I am wondering if I can get this portion of our house into compliance using this exception. Where is this exception written?
😍 those with the thick wood open 🙄😍👍
fantastic info. do you have more of these "all the code that applies to situation X" type videos?
Thanks for sharing this wisdom
Well, I was hoping to share this with my fellow inspectors and builders in my area (north texas), but we are using the 2015 irc and it is very different on the rise and run measurements
Yes, and I’m sure the codes you use for commercial /industrial stairwell construction will be different as well. Just like here in California.
Good job men good information
Good experience with your channel
Yes, its true, im too important for this video!!! Great vid about stairs.
I'll learned to do 7 11 on steps and our Max hight is 7 3/4
What about 8 inch risers at bottom of stairs before a landing then 6 inch risers above landing?..
Thanks!
Q: if the best practice is the 17" is the Luxuries height and length, or will it always be 17"? I've been to some resorts where it feels like, I'll never get to the top/bottom of their stairs.
are old stairs granfathered? I'm replacing a cheap spiral to the basement, and want to put stairs back in. two story row home. 94 inch to basement floor. horizontal head room from finished floor is 102 inches. how do you make this stringer? stairs from first floor to second floor has 12 steps, and the angle of steps are 47.5 degrees, tread is 10" hieght is 8.375.
Wish they could come build for me!
Do you guys do all the building from start to finish? Framing and finish work?
Well done!
SWEET Stairs!!
Awesome video! Can you tell me where to get the brackets under the stairs @ 9:08 ?
I’m a Ironworker and I’m looking for a book with all the codes that deal with metal stairs,ramps,handrails,Ship ladders, Formulas to build and take measurements etc. Thank you!
Sounds good, but you will most likely need to purchase a number of code books and other publications to cover your list. Good hunting.
Say you have a set of stairs from a garage to interior space. The door at the of the top of the stairs has a threshold higher than the interior finished floor. Where should you measure to for a consistent rise height?
Excellant
Thanks dude!
huaaa ! that's just for the stairs alone ! what more for the whole house !?? you guys are really well-rounded in your trade. i really love carpentry but haven't got the chance to learn it well. and guys I'm also having difficulty using the english measurement :) , btw, your explanation could be better understand by the uninitiated and trying-hard to be carpenter like me by explaining it with the real thing, hope you got me :). just my 2 cents anyways.
Recently the government of British Columbia put their building code books online with for everyone to use for free.
They only did that because the NRC which the develops the building code of canada which the bc code is based on recently became free to access online. Otherwise they would still be gouging us.
Gotta love spending 500 on it just 6 months ago.... 🤯
I dont get why it shouldn't be publicly online for yeaaaars ago... in every country in the world this kind of info should we available online. Why pay for something like this ?
Yes this exactly waht happendin USA also many people in RUclips never share the links to get the same access to public information
36in wide ateast or just 36in?
How long does it take to build a shed?
@1:49 the stringers didn’t sit on top of the platform. What was the reason the first step was added on like it was?
Good info.
is it a code to double up on stringers at the edges? because I see you guys did that
What code are you talking about? It is not the IRC which is what most places in the US use. Max rise is 7 3/4" and minimum tread is 10". Other stuff is wrong too, but people need to check local codes for themselves.
I LOVE BUILDING HOMES BUT I'M SO BAD IN CONSTRUCTION
Do u remodel homes in Wyndmoor PA?
I want to b passive, off-grid,
net zero
As a trim carpenter { the guy that installs the doors} I have explained this countless times to my latino friend who lays the tile.Still doesn't get it.Still finishes to the center of the stud.
Damn, a lot more codes with stairs than I realized
What’s the code for dimensions in which your stairs can be from the front door?
