What happens in this clip
Using a tape measure, extend it vertically (plumb) from the nosing (front edge) of a stair tread to the top of the handrail. According to code, this measurement, which is the height of the railing, should be between 34 inches and 38 inches. The presenter demonstrates that the railing in the video is too low, indicating a code violation.
Goal: Determine if the railing height meets code standards
What's used
Tools
- Tape Measure Stanley
- Yardstick
About the full video
This project provides a guide on how to inspect a staircase for common safety hazards and building code violations, focusing on railing height, open riser spacing, and baluster/cable spacing. The video highlights the importance of these measurements for preventing accidents, especially involving young children, and offers advice on how to address identified issues during a home purchase.
Step 4 of 5: Install or Reinforce Railings
Check that all railing posts are firmly anchored into the ground or the stair structure. Tighten any loose bolts or screws. If railings feel wobbly, reinforce them by adding extra bracing or securing them more deeply. Ensure the railing height meets local building codes for safety (typically between 34 and 38 inches above the stair nosing). If existing railings are insufficient or damaged, consider replacing them or installing additional support. The graspable surface of the railing should be continuous along the length of the stairs.
