I haven't kept up with building codes in a number of years, but believe it was 36" minimum landing at bottom or top of stairs. You need to check out the National Building Code to verify. You can Google this information online,
check for a copy at your local library or make a call to your local building department.

Residential Code on Stairways. You still need to verify that this information is current and suggest you contact your local building department.

Stair lifts are commonly installed in garages. Many garages are built below the grade of the house and require steps to access the living area. If the garage is fully enclosed an interior stair lift model can be used. If the garage is open (no doors) an outdoor unit may be more suitable in humid areas of the country.
A two way switch is required for staircase wiring. A staircase switch will have two terminals. Connect the line wire with the center terminal. Connect the two ends of a wire with the top two terminals and two ends of a wire with the bottom two terminals. The line wire at the center terminal can now be connected with one terminal of the light bulb or light holder.
Newel posts are used at each end of stair balustrading with spindles or balusters along the length supporting the handrail.
Stair lifts by manufacturers such AmeriGlide are said to be well favored by customers and incredibly easy to install. Electric powered stair lifts are said to be more difficult. However, battery powered stair lifts are easier for installation.
The formula for calculating the slope of a staircase is: slope rise / run. This means you divide the height of the stair rise by the depth of the stair run to determine the slope of the staircase.
To install vinyl stair nose on your staircase, first measure and cut the stair nose to fit the width of each step. Next, apply adhesive to the back of the stair nose and press it firmly onto the front edge of the step. Use a rubber mallet to ensure a secure bond. Repeat this process for each step until the staircase is complete.
To calculate stair stringers for a staircase, you need to determine the total rise and total run of the staircase. Then, you can use a mathematical formula or an online calculator to find the length and angle of the stair stringers. This will help you cut the stringers accurately to ensure a safe and stable staircase.
To properly install laminate stair nose for your staircase, follow these steps: Measure and cut the stair nose to fit the width of the staircase. Apply construction adhesive to the back of the stair nose. Press the stair nose firmly onto the front edge of the stair tread. Secure the stair nose in place with finishing nails or screws.

A flight of stairs in it's entirety is a staircase
The number of stair stringers needed for a staircase depends on the width of the stairs and the building codes in your area. Typically, you will need one stringer for every 16 inches of stair width. It is recommended to consult with a professional to determine the exact number needed for your specific staircase design.
There are companies dedicated to staircases, such as Stair Plan, which will be happy to help. Alternatively, most interior design companies will be perfectly willing to get involved with a staircase project.
A stair stringer is what holds up the stairs. Usually, a staircase has at least two of these supports to hold it up.
Stair tread rugs are used to decorate staircase steps. They can also be used for protecting the floor of a staircase from dirt on someone's shoes or damages to the floor such as a burn or a scratch.

The best method for installing vinyl floor stair nose on a staircase is to measure and cut the stair nose to fit the width of the stairs, apply adhesive to the back of the stair nose, and then press it firmly into place on the edge of the stair tread. Make sure to follow the manufacturer's instructions for the specific adhesive and installation process.
