https://www.homebuildingandrepairs.com/codes/stair/index.html - Thinking about adding a curved or radius step to the bottom of your staircase? Before you make any cuts, you need to understand the 3/8-inch variance rule!
In this video, we break down the building codes surrounding stair tread depth and riser height to show you why certain radius designs will fail inspection and how to do it right. We explain why cutting into the stair path creates an illegal variation, and show you exactly how to extend your bottom step safely so you stay code-compliant.
What you'll learn in this video:
The maximum allowable variation for stair treads and risers (the 3/8" rule).
Why removing a section of the bottom step for a curve is a code violation.
How to properly extend a radius past the edge of the stairway.
Why you always need to double-check with your local building authorities.
Disclaimer: Building codes can vary by city and county. Always check with your local building authority or a licensed contractor to verify the specific codes and regulations in your area before starting your project.
