Deck Boards for Stair Treads: A Viable Option with Considerations

Yes, you can absolutely use deck boards for stair treads. It’s a common and often practical choice, especially for outdoor staircases connected to decks. However, certain factors need to be considered, including building codes, the type of deck board, and specific safety measures, to ensure a secure and long-lasting staircase.

Why Use Deck Boards for Stair Treads?

• Aesthetic Consistency: Using the same material for both the deck and the stairs creates a seamless and visually pleasing transition.
• Material Efficiency: If you have leftover deck boards from your project, utilizing them for the stairs can minimize waste and save costs.
• Durability: Deck boards are designed to withstand outdoor elements and foot traffic, making them suitable for stairs as well.

Key Considerations When Using Deck Boards for Stairs

• Building Code Compliance:
  • Thickness: Ensure the deck boards meet the minimum thickness requirement for stair treads, typically around 1 ⅛ inches.
  • Nosing: Some codes mandate a nosing (a rounded edge projecting beyond the riser) for added safety. If your deck boards don’t have a built-in nosing, you might need to add one separately.
  • Slip Resistance: Stair treads must provide adequate grip to prevent slips and falls. Consider deck boards with textured surfaces or apply a non-slip coating if necessary.
• Type of Deck Board:
  • Composite Decking: Offers excellent durability, low maintenance, and various textures for enhanced grip.
  • Pressure-Treated Lumber: A budget-friendly option that requires regular sealing and maintenance to prevent rot and decay.
  • Hardwood: Provides a natural aesthetic and longevity but can be more expensive and require periodic refinishing.
• Safety Enhancements:
  • Lighting: Adequate lighting is crucial for safe navigation, especially at night.
  • Handrails: Install sturdy handrails on both sides of the staircase for added support and stability.

Additional Factors and Trends

• Staircase Design: The type of staircase (straight, curved, spiral) might influence the suitability of certain deck boards.
• Climate: Consider the local climate and weather conditions when choosing the type of deck board.
• Accessibility: If the staircase needs to be accessible to people with disabilities, ensure it complies with ADA guidelines.

Conclusion

Utilizing deck boards for stair treads can be a practical and aesthetically pleasing solution. However, prioritize adhering to building codes, selecting the right type of deck board, and implementing safety measures to ensure a durable and secure staircase.
