Can You Modify Existing Stairs to Make Them Less Steep?

Brief Summary

Yes, you can modify existing stairs to make them less steep, but the extent of the modification depends on your home’s layout, budget, and building code requirements. The most common methods include extending the staircase run, adjusting riser height and tread depth, or reconfiguring the staircase with landings or winders.

Methods to Reduce Stair Steepness

• Extend the Staircase Run:
  • Principle: Increasing the horizontal distance (run) of the staircase reduces the steepness.
  • Implementation: This typically involves extending the staircase into the lower floor, requiring adjustments to floor framing and potentially affecting the layout of the space.
  • Benefits: Often the most effective way to significantly decrease steepness while maintaining comfortable step dimensions.
  • Challenges: Requires substantial construction work, potential impact on space planning, may require permits and professional expertise.
• Adjust Riser Height and Tread Depth:
  • Principle: Lowering the riser height and/or increasing the tread depth decreases the stair angle, making them less steep.
  • Implementation: May involve modifying existing stringers, adding new treads, or adjusting the overall rise and run of the staircase.
  • Benefits: Can be less invasive than extending the run, particularly for minor adjustments.
  • Challenges: Limited by available space and building code requirements for minimum tread depth and maximum riser height.
• Reconfigure the Staircase:
  • Add Landings: Introducing intermediate landings breaks up the staircase into shorter flights, reducing the overall steepness.
  • Incorporate Winders: Winders are triangular or pie-shaped treads that allow the staircase to turn corners. They can be used to reduce the steepness of a straight run, but require careful design and can be more challenging to navigate.
  • Benefits: Can offer design flexibility and potentially improve space utilization.
  • Challenges: Adds complexity to the construction and may require significant structural modifications.

Building Code Considerations

• Riser Height and Tread Depth: Building codes in the USA stipulate maximum riser height (usually 7 ¾ inches) and minimum tread depth (typically 10 inches with nosing). Any modifications must adhere to these requirements.
• Headroom Clearance: Ensure that any changes to the staircase don’t compromise the required headroom clearance above the stairs.
• Handrail Requirements: Handrails must be continuous throughout the staircase and meet specific height and graspable dimensions.
• Permits and Inspections: Depending on the extent of the modifications, you may need to obtain building permits and schedule inspections to ensure compliance with local codes.

Remodeling Trends

• Focus on Safety and Accessibility: Homeowners are increasingly prioritizing safety and accessibility in staircase design, opting for gentler slopes and wider treads.
• Open Risers: Open riser staircases, while popular for their modern aesthetic, can be perceived as steeper. It’s crucial to carefully consider riser height and tread depth in these designs.
• Multi-Functional Staircases: Staircases are increasingly integrated into the overall living space, serving as design elements or incorporating features like built-in storage or seating.

Conclusion

Modifying an existing staircase to make it less steep is achievable, but requires careful planning and consideration of structural constraints, building codes, and safety guidelines. Whether through extending the run, adjusting riser and tread dimensions, or reconfiguring the staircase, prioritize safety and functionality while achieving your desired aesthetic. Consulting with a professional stair builder or architect can help ensure a successful and code-compliant renovation
