Before constructing your outdoor stairs, you need to assess several factors. Start by identifying the precise location. Consider the layout of your yard and the flow of foot traffic. The terrain's slope will dictate the stair design and complexity.
Measure the Total Rise and Run: The total rise is the vertical distance from the bottom to the top of the stairs. The total run is the horizontal distance the stairs will cover.
-
Calculate the Number of Steps:
- Rise per step (ideal is 7 inches)
- Run per step (ideal is at least 11 inches)
Use this formula: Total Rise ÷ Rise per step = Number of steps
Choose Your Materials:
| Material | Durability | Cost | Maintenance |
|---|---|---|---|
| Wood | Medium | Variable | High |
| Stone | High | High | Low |
| Concrete | High | Medium | Low |
| Metal | High | High | Medium |
Select materials that complement your home's exterior and landscape, and ensure they are suitable for your climate.
Consider Safety and Compliance:
- Tread Depth and Riser Height: Local building codes standardize these dimensions for safety.
- Handrails: Required if your stairs have a certain number of steps; check local codes.
Your design must balance aesthetic appeal with functionality. Ensure clear, level landing areas at the top and bottom of the stairs. Look up local building codes to guide your material choices and dimensional requirements. Obtain any necessary permits before proceeding with construction.
Materials and Tools Required
When building outdoor stairs, selecting appropriate materials and having the right tools are crucial to the success and durability of your project.
Choosing the Right Materials
Your materials need to withstand the elements and match the aesthetics of the surrounding area. Use pressure-treated lumber for the structural framing due to its resistance to rot and pests. For the treads and risers, options include natural wood (like cedar or redwood for beauty and durability), composite materials (for minimal maintenance), or even stone or concrete (for longevity and solidity).
List of Materials:
- Pressure-treated lumber: For stringers and support
- Cedar, redwood, or composite boards: For treads and risers
- Concrete or stone slabs (optional): For treads
- Galvanized or stainless steel screws and nails: For fastening
- Joist hangers: For additional support
- Concrete: For securing posts
- Gravel or sand: For foundation layer
Essential Tools for Construction
To ensure efficient and accurate construction, equip yourself with a set of essential tools. A circular saw or miter saw is required for precise cuts. A drill with various bits is needed for creating pilot holes and driving screws. Additionally, use a carpenter's square and level to ensure stairs are even and properly aligned.
List of Tools:
- Circular saw or miter saw
- Drill with assorted bits
- Carpenter’s square
- Level
- Tape measure

Designing the Staircase
Proper staircase design is crucial for both aesthetics and functionality. Adhere to local building codes and consider the comfort and safety of users during the design process.
Determining the Rise and Run
Rise refers to the vertical distance from the top of one step to the top of the next. Run is the horizontal depth of one step. For outdoor stairs, a comfortable rise is typically about 6 inches, with a run of around 12 inches, but these measurements can vary based on your landscape and intended use. Use this formula to calculate the total number of steps:
Total Number of Steps = Total Rise / Individual Rise
Ensure the rise and run are within the limits set by local codes.
Calculating Step Dimensions
Calculate the dimensions of each step using the rise and run determined earlier. For consistency and safety, all steps should have the same dimensions. Use the following guidelines:
- Tread Width: At least 10 inches for secure footing.
- Riser Height: Should not exceed 7 ¾ inches in height.
Apply these formulas for precision:
Tread Width (the run) = Total Run / (Total Number of Steps - 1)
Riser Height (the rise) = Total Rise / Total Number of Steps
Layout and Visualization
Create a detailed drawing to lay out the dimensions of your staircase. This visual aid:
- Helps avoid miscalculations.
- Provides a reference during construction.
Start with a side profile of the staircase to plot out each step. Ensure that all treads and risers are marked accurately. For an accurate depiction, consider using graph paper or a digital design tool which allows each square to represent a set measurement for precise scale.
Building Codes and Legal Considerations
Before starting your outdoor staircase project, check local building codes and regulations. These rules define the minimum requirements for safety and are legally enforceable. Non-compliance can lead to fines or being required to rebuild the structure, so it's crucial to understand and follow these guidelines. Building codes typically cover the following:
- Stair Width: The minimum width for stairways.
- Tread Depth: The horizontal distance from the front to the back of a tread.
- Riser Height: The vertical distance between each step.
- Landings: Required dimensions and placement for landings.
- Handrails: Height, strength, and placement specifications.
To begin, identify your local building department, which can provide relevant codes and ensure you obtain necessary permits. Permits are not just paperwork; they are for your safety and usually entail an inspection to certify proper construction.
Zoning laws may also affect stair placement, especially regarding property lines and environmental restrictions. In some areas, there may be historical preservation considerations. If your property falls within a historic district, additional oversight might exist to maintain the area's architectural integrity.
Keep your project compliant by consulting with a professional. A licensed contractor can offer valuable insights and help navigate complex regulations. Additionally, some codes vary significantly between locations, making local expertise essential.

Using stakes and string, outline the footprint of your staircase. Measure the total run (length) and the total rise (height) to determine the number of steps and their individual dimensions. For proper alignment, use a carpenter's square at each corner, and verify the measurements with a measuring tape.
Excavating and Leveling
Remove the topsoil and organic material from the stair location down to the subsoil using shovels and pickaxes. Dig out a few additional inches to allow for a gravel base, which aids in drainage and stability. Use a level and tamper to flatten and firm the subsoil. Check for evenness across the entire area to prevent future shifting or settling of the stairs.
Constructing the Stringers
Stringers are the backbone of your outdoor stairs, providing the essential support for the steps. Correctly cutting and attaching stringers is critical for a safe and stable stairway.
Cutting the Stringers
- Measure the total rise and run of your stairs.
- Total rise: Vertical distance from the ground to the deck or landing.
- Total run: Horizontal distance from the beginning to the end of the stairs.
- Calculate the number of steps and the height of each riser.
- Divide the total rise by the height you want for each riser, often 7 inches, to determine the number of steps.
- Your riser height is the total rise divided by the number of steps.
- Create your stair pattern on a 2x12 piece of lumber.
- Use a framing square to mark out each step, which consists of a tread and a riser.
- Ensure the tread depth (run) is consistent, typically 10 to 11 inches.
- Cut out the stringers carefully with a circular saw and finish the cuts with a handsaw.
- Avoid overcutting at the corners to maintain structural integrity.
Attaching Stringers to the Structure
- Attach a ledger board to the structure at the desired elevation if necessary.
- The ledger board supports the top end of the stringers.
- Use lag screws or carriage bolts to secure the ledger board to the structure.
- Position the stringers properly so that they are evenly spaced and aligned.
- Typical spacing is between 16 to 24 inches on center.
- Secure the stringers to the ledger board and the landing pad at the bottom.
- Use galvanized decking screws or specialized stair stringer connectors for a stronger hold.
- Make sure all stringers are level and plumb.
- Reinforce the stringers by attaching additional support if the stairs are wide or bear heavy loads.
- Install intermediate stringers for wider stairs.
- Use cross bracing between stringers for extra stability.
