Planning Your Deck Stairs

When planning your deck stairs, you need to calculate the total rise, and number of risers and treads, and also consider the location of the stairs while adhering to code requirements.

To ensure a safe and functional set of deck stairs, careful planning is crucial.

Determine the Total Rise to the Deck Landing

To figure out the total rise to the deck landing, measure from the ground up to the top of the deck surface. This tells you how high your stairs need to go. You use this height to plan how many steps you’ll need.

The total rise is a key starting point for your stair project. It helps make sure your stairs end right at your deck, not too high or low. So, get this measurement right before moving on to other steps in building your deck stairs.

Calculate the Number of Risers

To find the number of risers, first measure the total rise from the ground to the deck landing. This is the height your stairs need to cover. Divide this number by 7, which is an ideal height for each step in inches.

If you get a decimal, round it up. This gives you the total number of steps needed.

For example, if your deck is 28 inches off the ground, dividing by 7 gives you exactly 4. So, you need four risers for comfortable stepping. Always check with local building codes because they may have specific requirements for stair risers and treads.

Understanding how many stair risers you need ensures safety and compliance with local building codes.

Calculate the Number of Treads

To calculate the number of treads for your deck stairs, start by subtracting one from the total number of risers. Since each step down requires a tread, except for the last riser that meets the deck, this subtraction adjusts for that.

If you have 8 risers, you’ll need 7 stair treads.

Next, choose your tread material and size. Most decks use 2×6 wood for treads. Measure their width to ensure they fit well with your planned stair layout. For safety and comfort, aim for a tread depth between 10 to 11 inches.

This depth provides enough foot space on each step.

Plan the Location of Stairs

To plan the location of your deck stairs, start by choosing a convenient and safe area for access. Ensure that they don’t interfere with the deck’s function or obstruct walkways. Consider including handrails to enhance safety and accessibility.

Once you’ve determined your stairway’s location, make sure to review local building codes to ensure compliance with requirements such as width, rise, tread depth, and railings. A common guideline is that each step should have a maximum rise of 7-3/4 inches and a minimum tread depth of 10 inches.

This helps in ensuring safety and adherence to regulations while giving access to elevated areas.

Be Aware of Code Requirements

When building deck stairs, it’s crucial to be aware of local building code requirements. These codes specify the height and depth of each step, railing height and spacing, as well as load requirements for steps and railings.

Following these regulations ensures that your stairs are safe and up to standard.

Familiarize yourself with the International Residential Code (IRC) guidelines or consult with your local building department to understand specific code requirements for your area.

Adhering to these standards will help you avoid potential fines and ensure the safety of anyone using the stairs. Always keep in mind that meeting code requirements is essential when constructing deck stairs.
