Building deck stairs without a landing is a practical solution for many homeowners looking to optimize space and simplify construction. This design approach is particularly effective for shorter stair runs where a landing would be unnecessary or impractical. By eliminating the platform, you reduce both material costs and the time required for assembly, while still achieving a safe, functional connection between levels.
The structural integrity of a deck staircase depends on precise calculations and careful execution. Without a landing to break up the journey, each component—from stringers to treads—must work together seamlessly to handle vertical transitions. Attention to local building codes and proper joist hangers is essential, as is accounting for the total rise and run to ensure comfortable, code-compliant steps.
Planning Your Stair Layout
Before cutting a single board, accurate measurements are critical. Begin by determining the total vertical rise from the deck surface to the ground. This figure dictates the number of steps and helps establish the required run. A standard rise of 7 to 7.5 inches and a run of 10 to 11 inches typically results in a comfortable climbing angle.
Calculating Step Dimensions
Use a simple formula to divide the total rise by your chosen riser height. The result is the number of steps. Multiply this by your desired tread depth to confirm the horizontal run fits your available space. Double-check these calculations with a framing square to ensure accuracy before proceeding.
Required Materials and Tools
Efficient construction starts with having the right materials on hand. Pressure-treated lumber is recommended for stringers, treads, and risers due to its resistance to moisture and decay. You’ll also need galvanized screws or nails, concrete deck posts for support, and adjustable joist hangers for secure connections.
- 2x12 or 2x10 stringers (pressure-treated)
- Treads and risers matching your deck material
- Galvanized fasteners for outdoor use
- Concrete support posts and brackets
- Joist hangers and post base hardware
Constructing the Stringers
Cutting the stringers is a foundational step. Lay out your calculated rise and run on the lumber using a framing square, then trace the notches for each step. Use a circular saw to make the initial cuts, finishing with a handsaw for precision. These stringers will serve as the skeleton of your staircase.
Space the stringers approximately 16 inches apart, depending on the thickness of your treads. Secure them with joist hangers attached to the deck rim joist, ensuring they are level and properly aligned. For additional support, consider adding a central support post beneath the midpoint of the stair run.
Installing Treads and Risers
Once the stringers are in place, attach the treads starting from the bottom. Ensure each tread is flush with the stringer edge and fastened securely with corrosion-resistant screws. Leave a small overhang for aesthetic appeal and slip resistance.
Risers can be installed vertically between treads for a cleaner look and added safety. Cut each riser to match the calculated height and attach them with nails or screws. For an open-riser design, skip this step, but verify that the gap does not exceed local code specifications.
Final Checks and Safety Measures
Before regular use, conduct a thorough inspection of the entire structure. Check for any loose connections, uneven treads, or protruding hardware. Test the stairs by walking up and down slowly, noting any movement or instability.
Consider adding handrails if the stairs are particularly steep or long, even if not strictly required by code. Non-slip treatments, such as textured paint or adhesive treads, can enhance safety during wet conditions. Proper maintenance, including tightening screws and sealing cuts, will extend the life of your deck stairs.
