Which Staircases Have Intermediate Landings Between Floors

When it comes to staircases with intermediate landings, the International Building Code (IBC) plays a significant role in determining which ones are required. The IBC specifies that stairways with four or more walks must have a landing at each change in direction.

In many residential buildings, especially those with two or more stories, intermediate landings are a common feature. These landings provide a safe resting spot for people navigating the stairs and can be especially helpful for those carrying heavy loads or with mobility issues.

Some staircases, like those with a straight run of more than 12 feet, require intermediate landings to prevent long, tiring walks up or down. This is especially true in commercial buildings where workers may be on their feet for extended periods.

Straight stairs with an intermediate landing can be a good option for those who need a resting point while going up and down the stairs.

The main disadvantage of this type of stair is the space they require.

An alternative to straight stairs is the quarter turn stair, also known as L-shaped stairs.

Straight stairs are a common and practical choice for many buildings. They are a straightforward design that can be customized to fit different spaces.

One advantage of straight stairs is the space they require, which can be a major factor in smaller buildings or apartments. They don't need a lot of room to turn around, making them ideal for tight spaces.

In addition to being space-efficient, straight stairs with intermediate landings provide a resting point for those going up and down the stairs. This can be especially helpful for people who need to take breaks or for those who are carrying heavy loads.

Building codes require straight stairs with intermediate landings when the staircase needs to be more than 12 feet high. This is an important safety feature that helps prevent accidents.

Straight stairs can also help with privacy by providing a visual barrier between floors. If the stairs are contained within walls, they can also help prevent sound traveling between floors.

Quarter turn stairs are a great option for small spaces, as they take up less room than straight stairs. They can even be used in the corner of a room.

The design of quarter turn stairs makes them easier to navigate and safer than straight stairs, with a landing that provides a place to rest and reduces the number of stairs you could fall down at a time.

However, quarter turn stairs are more complex and therefore more expensive to build than straight staircases, requiring a support structure for the landing and the turn.

Handrails for quarter turn stairs also require more skill and planning to build than handrails for straight stairs.

Bifurcated Stairs are typically used in the entryway of a very upscale and roomy home.

They were also an iconic feature of the ship Titanic, which is a testament to their grandeur and elegance.

Bifurcated Stairs are characterized by a large, wide set of steps that lead to a roomy landing with two narrower flights branching off to the right and left.

This design creates a sense of drama and sophistication, making it a popular choice for luxury homes.

A mid-level landing is a great way to break up a long staircase, providing a resting point for those going up and down the stairs.

In commercial buildings, straight stairs with an intermediate landing are often used, but they can also be used in residential outdoor applications, such as steps from decks providing access to areas below.

The extra landing is an extra cost over a simple straight stair design.

The height of the landing does not have to be half the Total Rise, you can build a landing along any one of the calculated Step Heights.

For example, if you use the Automatic Stair Calculator to calculate the Number of Steps and the Typical Step Height on a Total Rise of 120 inches, the Typical Step Height would be 7 1/2 inches and the number of Steps on Stringer would be 15.

In this scenario, the landing is the third step, leaving 12 remaining treads to build from the top of the landing to the Total Rise.

A unique perspective: Stair Rod

The vertical height between the lower and upper landing is 60 inches, but the horizontal distance between the two landings is too far for a 2x12 stringer.

You can use a landing as a step to fill in the gap.

To determine the height and length of the mid-level landing, think of the landing as being one of the steps on the stringer above.

You can locate the landing on any step along the stringer, and the stringer step you choose will determine the landing's finished height and the placement of this landing between the upper and lower levels.

The finished landing height is determined by the number of steps multiplied by the Step Height, for example, 5 * 7.5" = 37.5".

The horizontal distance from the lower landing is determined by the number of Steps on the lower stringer multiplied by the Tread Depth, for example, 4 x 10.5 = 42".

The length of the mid-level landing is calculated by subtracting the run of the lower stringers plus the run of the upper stringers from the overall span of the stair/landing combination.

Stair design considerations are crucial when deciding which stairs to install in your home. A central landing can break up a long expanse of stairs, making them more manageable.

Building codes require a straight staircase with an intermediate landing when the staircase needs to be more than 12 feet high. This type of staircase is also useful for providing privacy and preventing sound from traveling between floors.

The intermediate landing on a straight staircase provides a resting point for those going up and down the stairs, making them a practical choice for homes with multiple floors.

Calculating Stair Requirements is a crucial step in stair design. It involves determining the number of steps, step height, and tread depth to ensure safety and accessibility.

The total height of your stairs can exceed building code limitations, requiring a landing to break up the run of stairs. This can also be a design choice to create a resting place or enjoy a view.

To design a stair stringer, you can use a stair calculator. For example, entering 60 inches in the Total Rise field and changing the Target Step Height to 7.5 inches results in a seven-step stringer.

The step height and tread depth can be determined using a stair calculator. In the example, the Step Heights are 7 1/2 inches and the Tread Depths are 10 1/2 inches.

A landing may be required if the slope of the terrain changes irregularly, ensuring each step rise stays the same. This can involve a series of level walkways between runs of stairs.

Straight stairs can provide a resting point for those going up and down, thanks to the intermediate landing.

The main disadvantage of straight stairs with an intermediate landing is the space they require.

Having a resting point can be a big advantage, especially for people with mobility issues or those carrying heavy loads.

However, the space required for straight stairs with an intermediate landing can be a significant drawback, especially in smaller homes or apartments.

Quarter turn stairs offer several advantages, including taking up less space than straight stairs and being easier to navigate and safer to use.

The landing provides a place to rest and reduces the number of stairs one could fall down at a time, making them a more practical option for many homes.

However, quarter turn stairs are more complex and therefore more expensive to build than straight staircases.

They require a support structure for the landing and the turn, which is often built into the surrounding walls.

Handrails for quarter turn stairs also require more skill and planning to build than handrails for straight stairs.

Large items can be difficult to move up and down the stairs due to the turn, which may require some creative problem-solving.

Straight staircases with intermediate landings are often used in large commercial buildings, but can also be suitable for residential outdoor applications like deck stairs.

They're generally more expensive than simple straight stair designs due to the extra landing.

A large landing can encourage climbers to rest, making the climb more comfortable.

In commercial settings, stairways must meet specific safety regulations, including a minimum width of 36 inches for occupant loads under 50 people.

Stairs over 12 feet tall require an intermediate landing, which should be the same width as the stairway and at least three feet long.

Handrails and guards are mandatory for open-sided walking surfaces, with no gaps allowed between them that could let a four-inch sphere pass through.

The International Building Code (IBC) dictates specific rise and tread measurements for each individual step, with closed risers between four and seven inches and treads at least 11 inches deep.

In some cases, straight stairs with intermediate landings can help with privacy by providing a visual barrier between floors, especially when contained within walls.

These stairs can also help prevent sound from traveling between floors when enclosed.

Straight stairs with an intermediate landing provide a resting point for those going up and down the stairs.

The main disadvantage of straight stairs with an intermediate landing is the space they require.

These stairs can be a good option for smaller spaces because they take up less room than a straight staircase with multiple landings.

However, they still offer some benefits, such as making it easier to navigate between floors.
