Do deck stairs need a landing?
SAFE, SUPPORTED STAIRS: Deck-stair construction varies, but the general requirements are consistent: proper footing support, and an adequate landing. Regardless of the stair run and number of treads, the stairway needs a footing at the bottom to support the stringers—they can’t just rest on the ground.
What should deck stairs land on?
Just like a deck, a landing needs to have footings, posts, beams, and joists. The minimum size for a landing is 3 feet by 3 feet or the width of the stair sections meeting at the landing—whichever is greater.
How long can deck stairs be without a landing?
A flight of stairs should not rise vertically more than 147 inches without a landing. An intermediate landing is a small deck, and should be built as such, including appropriate footings, posts, and bracing.
How do you attach stair stringers to landing?
Attach the stringers to the deck using angle brackets and 3” galvanized deck screws. Cut a 2×6 board to fit snugly between the two stringers at their base. This will be used to fasten the stairs to the concrete pad. Place the board between the stringers and attach to stringers with 3” galvanized deck screws.
How many stairs before a landing is needed?
– A landing is required every 12′ of vertical stairway rise. – The landing should be at least as wide as the stairway that it serves.
How thick is a stair landing?
Staircase Landings The width of the landing, measured perpendicular to the direction of travel, must be no less than the width of the staircase. The minimum depth, measured in the direction of travel, is 36 inches.
How thick should stair treads be?
According to general specifications, your stair riser thickness should be no less than ½”. In fact, many professionals recommend risers with a thickness of ¾”. It’s also important to note that if you do build a closed riser staircase, your stair treads will need to have a note as well.
Do I need a rail on my deck stairs?
If your deck is over 30 inches from the ground, then by law you need railings for the deck stairs. Low rise (aka floating) decks are less than 30 inches from grade and are exempt. Guardrails must be installed on a high deck or a balcony. Stair rails are a type of guardrail.
Do I need a concrete pad for deck stairs?
Building codes generally require that exterior stairways have a concrete footing or foundation. Without the foundation the steps will sink, heave or tilt to one side. This article shows how to build a 4-in. thick slab that will serve as a foundation for a set of deck steps.
Are stair stringers 2×10 or 2×12?
It is acceptable and within building code guidelines to use either 2×10 or 2×12 dimensional lumber to create a set of stairs; however, a stair stringer should not be less than 3.5 inches wide at its narrowest point to provide adequate strength for the load the stairs will be supporting.
What is the code for stair stringers?
Stair stringers should not span more than 13 feet and 3 inches (4039 mm) for a closed stringer. Cut stringers should not span more than 6 feet (1829 mm). Refer to the American Wood Council’s 2018 Prescriptive Residential Wood Deck Construction Guide for stringer spans.
How do you calculate stairs for landing?
How to Calculate Stairs – Example 1 450mm / 150mm = 3. This tells us that with a riser of 150mm we will need 3 risers/steps. 450mm / 2 = 225mm. Twice the Rise plus the Going (2R + G) should be between 550mm and 700mm. 2 x 150mm + 275mm = 575mm.
Is the landing considered a step?
The Total Run only applies to a single straight run of stairs. The height of each step is 6 7/8 inches. The mid-level landing counts as a step in this design. Both upper stair stringers and lower stair stringers have the same number of treads.
What is considered a stair landing?
Landing, or platform: A landing is the area of a floor near the top or bottom step of a stair. An intermediate landing is a small platform that is built as part of the stair between main floor levels and is typically used to allow stairs to change directions, or to allow the user a rest.
What is half landing staircase?
A half landing staircase gives the user a flat platform that is situated midway up the staircase, allowing the stairs to undergo a half (180°) turn, allowing it to ascend to a point that is better situated in the home, whether this is through preference or necessity.
How big should a landing be?
A minimum landing depth of 36 inches is specified in most building codes. In general, a landing need not be deeper than 4 feet, no matter how wide the stairs are, if it’s at the end of a straight run of stairs.
What is the standard step height for stairs?
Riser Heights In the United States, the step height standard should be between 7 or 7 ¾ inches at the most, and no less than 4 inches. You should follow other measurements if given by local building codes. In Canada, the maximum step riser height is 8 ¼ inches.
How wide should stairs be on a deck?
Deck Stair Basics Deck stairs are typically made from 2 x 12 stringers spaced about 12 to 16 inches apart. They rest on a solid foundation and are attached to the deck with hangers. They have risers (also called toe kicks), treads and railings. The stairs should be at least 36 inches wide.
At what height are stairs required?
Standard Stair Riser Height Requirements OSHA 1910.25(c)(2) requires standard stairs to have a maximum riser height of 9.5 inches (24 cm). IBC 1011.5. 2 requires that stair riser heights shall be 7 inches (178 mm) maximum and 4 inches (102 mm) minimum.
