Do Exterior Stairs Require a Landing?

When designing or installing exterior stairs, one question often arises: do exterior stairs require a landing? The short answer is yes, in many cases, they do. But let's delve deeper into the reasons behind this and explore the scenarios where landings are not only recommended but also legally required.

Exterior stairs are not just aesthetic features; they play a crucial role in ensuring safety and accessibility. And it's in the interest of these factors that landings are often integral to their design.

Understanding the Purpose of Landings

A landing provides a flat surface that interrupts the flow of stairs, allowing users to rest, change direction, or regain their balance. They also serve as a crucial point for installation of railings or banisters, enhancing safety and support.

In some cases, landings are not just a suggestion but a legal requirement, as dictated by building codes and regulations, to ensure the structural integrity and safety of the staircase.

Building Codes and Requirements

Building codes vary by region, but they often share similar provisions when it comes to exterior stairs. For instance, the International Residential Code requires a landing for each flight of stairs with more than four risers. This helps maintain safety by breaking up long, continuous flights of stairs that could pose a risk to users, especially in cases of emergency evacuation.

Similarly, in many regions, landings are required at the top and bottom of staircases, and at any point where the direction of the staircase changes, such as at a turn or where the staircase splits into branches.

Design Considerations for Landings

When designing a landing, it's essential to consider its size, shape, and placement. It should be large enough to accommodate users who may need to stop and rest, but not so large that it consumes excessive space. Typically, a landing should be at least 36 inches deep and 48 inches wide.

The depth of the landing is particularly critical as it should be equal to or greater than the tread depth of the stairs. This ensures a smooth transition and prevents users from having to step out of the normal walking line, which could lead to trips, falls, or stubbed toes.

The Importance of Landings in Accessibility

Landings also play a significant role in the accessibility of exterior stairs. For users with disabilities, such as those requiring wheelchairs or mobility aids, a landing provides a safe and spacious area to rest, maneuver, or transition between different levels.

According to the Americans with Disabilities Act (ADA) Standards for Accessible Design, stairways must have landings that are at least 60 inches square. This size requirement ensures that people using wheelchairs or mobility aids can safely change direction and navigate the staircase.

ADA Compliance and Exterior Stairs

When designing exterior stairs for accessibility, it's crucial to adhere to the ADA standards. This includes requirements for the height and depth of treads and risers, the width of handrails, and the presence of landings at intervals not exceeding 12 feet.

Failing to comply with these standards can result in legal liabilities and may also discourage people with disabilities from visiting or using your property. Hence, careful consideration of accessibility features like landings is not just a matter of safety and user experience but also of legal compliance and overall inclusivity.

Exterior Stair Design and Aesthetics

While safety and accessibility are the primary concerns, landings also serve an aesthetic purpose. They can add visual interest to exterior stairs, breaking up the monotony of a long flight and providing an opportunity to incorporate design elements like decorative railings, artistic tiles, or lush plant life.

Moreover, a well-designed landing can make a space feel more spacious, welcoming, and inviting. It can serve as a transition point between different areas of a property, such as a patio and a garden, or a covered entryway and an outdoor seating area.

When to Consider Alternatives to Landings

While landings are often the best solution for exterior stairs, there are limited circumstances where an alternative might be suitable. For instance, in properties with extremely limited space, a continuous, switchback staircase might be the only feasible option. However, even in these cases, landings should be considered if at all possible, given their safety and accessibility benefits.

Another alternative is to use open-stringer stairs, which have open risers and thus eliminate the need for a landing for changing directions. However, this design can pose safety risks, particularly for young children or pets, so it should be carefully considered and may require the installation of safety gates or other protective measures.

In summary, while there may be rare exceptions, exterior stairs typically do require a landing. Landings aren't just a matter of aesthetics; they play a critical role in safety, accessibility, and even legal compliance. By carefully designing and integrating landings into your exterior stairs, you can create a safe, welcoming, and compliant space for all users. Always refer to your local building codes and ADA guidelines to ensure your design meets all necessary requirements.
