- stairs4u.com/st... Click on this link for more information about stair building codes. Remember to always check with your local building department and the information in this video might not apply to your area. This video will provide you with information for exterior door openings or egress to the building as it concerns stairways, decks, balconies, porches and platforms. More information can be found on page 248 of the 2012 International Building Code.
Hey there I search for building codes and structural content online and over the last couple of years your videos come up as suggestions. I've watched many of your videos and they are always very informative, and simple to understand. Just wanted to thank you for posting this information. They really help me when I am starting a new project and need some specifics on the plan. Keep it up!
You're welcome and I sincerely enjoy reading comments like yours.
I'm in the process of this right now and it's good to see you have the same understanding of the codes as I have. I installed a french door where a window once was and was told I had to have a landing. The doors are 36 inches long so the code says it has to have a landing 44 inches in the direction of egress. I guess I could get away with 36 inches since group R-1 isn't really covered but for safety, I'm going to go with a 44" landing. It's only 19 inches above grade so no extra stair permit will be necessary (I already have a general permit for the work). I'm also in San Francisco Ca, where codes enforcement is very strict.
thank you for this video as I am building a set of steps into a retaining wall I needed to know if I am allowed to have a small step off the top landing to the finish ground level which is only 2 inches
As long as it meets your local building codes. Usually the smallest step is 10 inches in depth for stairs in homes.
The height is to the top of finished floor and not the top of threshold, correct? Im fixing to build my steps from the garage to house.
I would love to provide you with an answer to that question, but it might be confusing the other viewers. I would suggest contacting your local building and safety department for an answer to this question.
You need a landing at all exterior doors, with the exception of 2 or few risers on residential.

1010.1.6 Landings at Doors
Landings shall have a width not less than the width of the stairway or the door, whichever is greater. Doors in the fully open position shall not reduce a required dimension by more than 7 inches (178 mm). Where a landing serves an occupant load of 50 or more, doors in any position shall not reduce the landing to less than one-half its required width. Landings shall have a length measured in the direction of travel of not less than 44 inches (1118 mm).
Exception: Landing length in the direction of travel in Groups R-3 and U and within individual units of Group R-2 need not exceed 36 inches (914 mm).
1011.6 Stairway Landings
There shall be a floor or landing at the top and bottom of each stairway. The width of landings shall be not less than the width of stairways served. Every landing shall have a minimum width measured perpendicular to the direction of travel equal to the width of the stairway. Where the stairway has a straight run the depth need not exceed 48 inches (1219 mm). Doors opening onto a landing shall not reduce the landing to less than one-half the required width. When fully open, the door shall not project more than 7 inches (178 mm) into a landing. Where wheelchair spaces are required on the stairway landing in accordance with Section 1009.6.3, the wheelchair space shall not be located in the required width of the landing and doors shall not swing over the wheelchair spaces.
Exception: Where stairways connect stepped aisles to cross aisles or concourses, stairway landings are not required at the transition between stairways and stepped aisles constructed in accordance with Section 1029.
Is there something I said in the video that was incorrect or are you just providing us with what the building codes suggested in 2015?
@@stairbuilding I believe he is referring to the staircase you begin covering at 1:29, which is an external staircase with no landing.
@@stairbuilding You show too many steps in the picture.
@@JDW240 the picture shows a landing at the bottom of the stairs and i believe the floor inside the house is considered the top landing.
@darrel Riley according to 2012 IRC, a landing is needed on each side of an exterior door.
I understand the 4 inch dimension referred to between interior floor and the exterior deck or landing. Does this apply to exterior opening doors and is there also a minimum dimension to prevent water intrusion?
thanks....
I would check with your building department.
Thank you! Good information.
You're welcome!
I have an exterior door to a garage. I have 12” of rise from grade to threshold. I was going to install 2 steps at 6” height a piece. My 36” wide door opens outward, into the steps. Do I need a 48” long x 36” wide landing at the top of my step at the threshold, before I step down to the last step before stepping onto the ground?
I would check with your local building department to answer your question. I would think that you would need a larger landing at the top of the stairs.
You do not need a landing. That is considered an interior stair so you are good into a garage.
I have a patio window in the kitchen but no deck, I purchased the house that way, My question, will that be a building code violation when i sell the house in Michigan? I await your response!! I did like your height of landing info.
If you're referring to a sliding glass door or something that will allow you to access the exterior, then you would probably need a set of stairs if it's higher than 7 1/2 inches off of the ground or a concrete slab if it's lower, but I would recommend checking with your local building department for more information.
Comparing these statements to the California Residential Code, I find most of these comments do not apply.
Yes, always check with local build codes.
You’re not using the 2015 Code book. The heights are addressed on page 67 section 311.3
Exactly what code book are you referring to?

@@terryturcotte7494 If you don't mind sharing the information, what does it say. It might not be useful to someone living in Nevada, but it might be useful to someone living in Michigan.
You have roofing book?
No, not yet.
