Considerations for Deck Stairs
Before we explore materials and designs, it's crucial to address key considerations that can impact the safety and functionality of your deck stairs. These considerations include:
1. Level Landing Spaces
Ensure that the landing space below the stairs is level and safe. Avoid unlevel ground or areas prone to water puddles, providing a secure transition from the stairs.
Here are the three top reasons why level landing spaces should be considered while designing your deck stairs:
- Safe Transition: A flat landing ensures a safe and stable area to step onto when using deck stairs, reducing the risk of accidents.
- Structural Integrity: A level surface supports the structural integrity of the stairs, ensuring they remain strong and durable over time.
- Water Drainage: A flat surface helps water drain away, preventing puddles and slippery conditions, enhancing safety, and preserving the stairs' materials.
2. Building Codes and Guidelines
Adhere to building codes when constructing stairs. Failure to comply might result in red-tagging by your local building department.
Here are the main building codes and guidelines you should follow while designing your deck stairs:
- Tread Depth: Building codes typically dictate a minimum stair tread depth, ensuring safe and comfortable stepping. It's essential to adhere to these guidelines for each step.
- According to Michigan deck-building regulations, “The minimum tread depth shall be 9 inches (229mm).”
- Stair Width: The width of the stairs should meet or exceed the minimum requirements outlined in building codes, ensuring easy and safe passage.
- According to Michigan deck-building regulations, “Stairways shall not be less than 36 inches (914mm) in clear width at all points above the permitted handrail height and below the required headroom height.
- Riser Height: Regulations specify the maximum height for each riser, promoting consistency and preventing uneven steps that could lead to tripping hazards.
- According to Michigan deck-building regulations, “The maximum riser height shall be 8¼ inches (210mm). The riser shall be measured vertically between leading edges of the adjacent treads. The greatest riser height within any flight of stairs shall not exceed the smallest by more than 3/8 inch (9.5mm).”
- Handrail Requirements: Building codes often mandate the installation of handrails for specific stair configurations and heights to enhance safety, especially for elevated decks.
- According to Michigan deck-building regulations, “Handrail height, measured vertically from the sloped plane adjoining the tread nosing, or finish surface of ramp slope, shall be not less than 34 inches (864mm) and not more than 38 inches (965mm).”
- Guardrails: For elevated decks, guardrails are essential. Building codes outline specific height and spacing requirements for guardrails to prevent falls.
- According to Michigan deck-building regulations, “Guards shall be located along open-sided walking surfaces, including stairs, ramps and landings that are located more than 30 inches (762mm) measured vertically to the floor or grade below at any point within 36 inches (914mm) horizontally to the edge of the open side. Insect screening shall not be considered a guard.”
3. Handicap Accessibility
For spaces requiring handicap compliance, installing ramps alongside stairs is a thoughtful addition, providing accessibility for those struggling with traditional staircases.
Here are a few more deck design ideas you can incorporate into your handicap-accessible stairs:
- Gentle Slopes and Landings: Use gentle slopes with flat areas for easy mobility.
- Wider Stairs: Build wider stairs for comfortable use, especially for those with mobility aids.
- Lift or Elevator: Install a small lift for multi-story decks to help people move easily between levels.
- Adaptable Handrails: Include handrails with different heights for added support and accessibility.
- Non-Slip Steps: Ensure steps have non-slip surfaces for improved safety, particularly for those with mobility challenges.
Deck Stair Designs
Beyond materials, the design of your deck stairs contributes significantly to the overall appeal. Consider the following design options:
1. Straight-Run Stairs
Cost-effective and suitable for decks not too far off the ground, straight-run stairs are a practical choice when space allows.
2. L-Shaped and U-Shaped Stairs
Compact your space with L-shaped or U-shaped stairs, allowing for larger staircases in smaller areas.
3. Switchback or Z-Shaped Stairs
Ideal for elevated decks, these designs use landings to break up long staircases, optimizing space and maintaining a visually appealing look.
4. Spiral Stairs
When space is limited, spiral stairs provide a code-compliant solution and a unique design element. Consider adding flair, such as a slide, for an innovative touch.
5. Flared or Grand Stairs
Wider at the base than the top, flared stairs offer a grand appearance, perfect for those looking to make a statement with their deck design.
Deck Stair Materials
Now, let's explore various materials suitable for deck stairs, each with its unique features:
1. Wood
A classic choice, wood stairs, particularly with pressure-treated lumber treads and cedar rails, offer an economical option. Regular maintenance, including sanding and resealing every 24 months, is necessary.
Here are the more pros and cons of wood deck stairs:
Pros:
- Renewability: Sourced from sustainable forests.
- Ease of Installation: Generally easier to work with for DIY projects.
- Affordability: Generally more affordable than some alternative materials.
- Customization: Can be easily customized to fit specific design preferences.
- Natural Aesthetics: Adds warmth and natural beauty to your outdoor space.
Cons:
- Slippery When Wet: Poses safety hazard when wet.
- Prone to Warping: Susceptible to warping over time.
- Insect Attraction: May attract termites and other insects.
- Maintenance: Requires regular sealing and staining to prevent decay.
- Limited Lifespan: May not last as long as some alternative materials.
2. Metal
Options like aluminum and steel provide durability. While pre-designed metal stairs offer design flexibility, they require consistent maintenance to prevent rust and weathering.
Here are more pros and cons to consider before choosing metal for your deck stairs:
Pros:
