Re: Step Riser Height


They also have to fix the deck framing along that whole front a wall, that's also out of square. They've got a lot to do before I step another foot on that project.

It's a brand new home it's the builders fix. I'm contracted by the HO which is the way I like it. Either way I'm not going to hammer one nail until it's right.

R311.7.4 Stair treads and risers. Stair treads and risers shall meet the requirements of this section. For the purposes of this section all dimensions and dimensioned surfaces shall be exclusive of carpets, rugs or runners.

R311.7.4.1 Riser height. The maximum riser height shall be 73/4 inches (196 mm). The riser shall be measured vertically between leading edges of the adjacent treads. The greatest riser height within any flight of stairs shall not exceed the smallest by more than 3/8 inch (9.5 mm).

R311.7.4.2 Tread depth. The minimum tread depth shall be 10 inches (254 mm). The tread depth shall be measured horizontally between the vertical planes of the foremost projection of adjacent treads and at a right angle to the tread's leading edge. The greatest tread depth within any flight of stairs shall not exceed the smallest by more than 3/8 inch (9.5 mm). Consistently shaped winders at the walkline shall be allowed within the same flight of stairs as rectangular treads and do not have to be within 3/8 inch (9.5 mm) of the rectangular tread depth.

Winder treads shall have a minimum tread depth of 10 inches (254 mm) measured between the vertical planes of the foremost projection of adjacent treads at the intersections with the walkline. Winder treads shall have a minimum tread depth of 6 inches (152mm) at any point within the clear width of the stair. Within any flight of stairs, the largest winder tread depth at the walkline shall not exceed the smallest winder tread by more than 3/8 inch (9.5 mm).

R311.7.4.3 Profile. The radius of curvature at the nosing shall be no greater than 9/16 inch (14 mm). A nosing not less than 3/4 inch (19 mm) but not more than 11/4 inches (32 mm) shall be provided on stairways with solid risers. The greatest nosing projection shall not exceed the smallest nosing projection by more than 3/8 inch (9.5 mm) between two stories, including the nosing at the level of floors and landings. Beveling of nosings shall not exceed 1/2 inch (12.7 mm). Risers shall be vertical or sloped under the tread above from the underside of the nosing above at an angle not more than 30 degrees (0.51 rad) from the vertical. Open risers are permitted, provided that the opening between treads does not permit the passage of a 4-inch diameter (102 mm) sphere.

Exceptions:1. A nosing is not required where the tread depth is a minimum of 11 inches (279 mm).2. The opening between adjacent treads is not limited on stairs with a total rise of 30 inches (762 mm) or less.

Re: Step Riser Height


7.25 is a good riser height most of the time, and is very common

Yep my cali inspector gives me the paper at every california state inspection, which states 4" minimum, which I never had a muni that didn't go by the state codes.

Re: Step Riser Height


The stairs on my deck are 10 risers at 5-7/8" with 11" treads, and they are very comfortable to use.

The let-in area for the steps was 42" on one side and 45" on the other. So with that said they will have to use the 7.25" risers. When I did the takeoff I didn't check both sides. I figured hell they framed the whole house you'd think I wouldn't have to check their work. Oh well they are fixing it now, gives me some time to get caught up.

Re: Step Riser Height


I don't like anything less than 7 personally, feels like a waste of time climbing short steps.

But for older folks less is better. I always start at 7" and find the closest number that gives me the overall rise, favoring steeper up to 7 1/2".

Obviously sometimes there are other considerations and you just have to do what works.

Re: Step Riser Height


And...you can talk an inspector out of the limits on riser height if the stair is not a primary egress. Lol.

And sometimes not. We were red tagged on a stair during framing inspection by a clown that didn't get the big picture. The bottom tread was 8 inches, and due to get laminate flooring, next tread was 7-1/2 and on up, landing tread was floor level above....and I pointed out that floor thickness would be 1/2 inch +, and he still wrote the red tag. My framer cut the stringers to make this clown happy, and then shimmed them back.

BTW, I shoot for 7-3/4 x 11 just because most people are taller now, and shorter steps are just not comfortable to most people now.

Re: Step Riser Height


Just keep it in mind fellas, for those who don't know the way interpretation of code compliance work to meet the stair variation within 3/8" ... You have to take the tallest rise and subtract the lowest rise and that should be within 3/8.Same goes for the width.

Here is an example.

Re: Step Riser Height


Personally I find the "stride" method Greg post in #21 to be very true to comfort.

A short step and stair is clumsy but when a short step has a wider tread you adapt easily in stride.

Re: Step Riser Height


Total run+rise should ~17-18", hence the 7/11 starting point.
Minimum IIRC is 4-3/8", anything over that is a "legal" step, may not walk right, but is legal. Not sure what the tallest legal step is, but I wouldn't go anywhere over 8-1/2". No more than 3/8" variance in a flight.
The customer is always right, and it is only a few steps.

Actually here in Cali it's 4" minimum.
