Is This A Small Angled Stair Landing or Step? - Building Codes And Architectural Design Tips
Angled steps, often found in winding staircases or as transitions between flights, can add a unique architectural element to a home. However, their design and implementation can be tricky, as building codes often have specific regulations regarding their use.
Angled Steps: Two Possible Classifications
An angled step can fall under two categories:
Winder Step: A step that is wider at one end than the other, typically used to change the direction of a staircase. Multiple winders form a winder staircase.
Landing: A platform between flights of stairs, providing a resting point and changing the direction of travel. An angled step can sometimes function as a small landing.
Building Code Considerations
Building codes often have strict rules regarding angled steps, especially when used as winders:
Tread Depth: Winder treads must maintain a minimum depth at a specific point (usually measured 12 inches from the narrower end) to ensure safe footing.
Riser Height: Riser heights in winder stairs must remain consistent with the rest of the staircase.
Headroom: Adequate headroom must be maintained above winder steps to prevent head injuries.
Handrail Requirements: Winder stairs typically require continuous handrails that follow the changing direction of the steps.
Why Consult Your Local Building Department
The classification of an angled step (winder or landing) can significantly impact code compliance. Here's why checking with your local building department is crucial:
Code Interpretation: Local officials can provide clarity on how your specific design will be interpreted under the local building code.
Variances and Exceptions: In some cases, you might be able to obtain a variance or exception to certain code requirements if your design meets specific safety criteria.
Avoiding Costly Mistakes: Building a non-compliant staircase can lead to failed inspections and expensive rework. Getting it right from the design phase saves time and money.
Key Takeaways for Stair Builders and Homeowners
Understand the difference between winders and landings.
Research local building codes regarding angled steps.
Consult with your local building department during the design phase.
Ensure your design meets all safety and accessibility requirements.
By understanding the building code implications and seeking expert guidance, you can confidently incorporate angled steps into your stair project while ensuring a safe and compliant structure.
