Stair tread side overhang is a small yet impactful detail that enhances both the function and aesthetic of a staircase.
This overhang refers to the portion of the stair tread that extends beyond the edge, giving stairs a sleek, finished look.
A well-planned side overhang can elevate the appearance of your staircase while making it safer and more durable.
Whether you’re working with indoor stairs or considering a deck stair tread overhang, the right overhang can improve both the appearance and usability of each step.
Adding carpet stair rugs can further enhance this design, bringing warmth and comfort to the space.
What is the Purpose of a Stair Tread Side Overhang?
A stair tread side overhang serves both a design and functional purpose.
While the side overhang is often not required by building codes, it can provide a polished look by covering exposed edges, especially on open-sided stairs.
This aesthetic addition makes a staircase look complete while offering a visual guide for each step, enhancing safety.
In most designs, the side overhang matches the front tread nosing, creating a balanced, seamless appearance along the staircase.
For both indoor and outdoor applications, this overhang adds style and practicality to your stairs.
Are Stair Tread Side Overhangs Required by Building Codes?
In most cases, building codes like the International Residential Code (IRC) primarily address the front tread overhang, not the side.
The front overhang, or nosing, should extend between ¾ inch to 1-1/4 inches over the riser to provide a safe, comfortable step.
Side overhangs, however, are generally optional and can be customized for aesthetics without needing to meet specific code requirements.
This flexibility allows you to adjust the side overhang to match the design of the staircase, whether it’s an elegant indoor style or a sturdy deck stair tread overhang.
Adding side overhangs to open stairs is a common choice for a more luxurious and finished look.
How to Add or Adjust a Stair Tread Side Overhang
Adding or adjusting a stair tread side overhang can be done with pre-finished treads that have extended edges, or by attaching trim pieces along the sides.
For outdoor stairs, selecting a deck stair tread overhang with durable, weather-resistant materials like composite or treated wood is ideal.
These materials can withstand outdoor conditions and provide a sturdy, secure edge for outdoor steps.
Many DIY stair tread kits include side and front overhang options, allowing you to match the overhangs for a cohesive appearance.
Adding this detail to indoor or outdoor stairs can increase safety while improving the overall style.
How Does the Side Overhang Compare to the Front Overhang?
Front and side overhangs on stair treads have different purposes.
The front overhang, or nosing, adds extra footing and is often required for safety on narrow steps.
In contrast, the side overhang is mostly decorative and hides any exposed wood on open-sided stairs.
Side overhangs contribute to a balanced, luxurious look, giving a staircase a seamless, professional finish.
For outdoor applications, like deck stairs, side overhangs reinforce the edge and provide a more durable step.
Both types of overhangs work together to make stairs safe, stylish, and inviting, especially when paired with additions like carpet stair landings for extra warmth indoors.
Steps to Success
Adding a stair tread side overhang is a simple way to upgrade the appearance and safety of your stairs.
For deck stair tread overhangs, choose materials that can handle outdoor conditions.
With options for both indoor and outdoor use, focusing on these details helps create a staircase that’s comfortable, durable, and stylish.
