Riser
Definition and meaning of Riser in real estate.
A riser is the vertical board or space that forms the height of a step on a set of stairs, positioned between one tread and the next.
In more detail
Stair risers can be closed, meaning they are solid pieces of wood or composite material, or open, which creates a floating look with gaps between the treads. Building codes strictly regulate riser height, usually requiring them to be uniform to prevent tripping hazards. The typical height is between six and eight inches in most residential jurisdictions. During a home inspection, mismatched riser heights are often flagged as safety defects that require correction.

Frequently asked questions
What is the difference between a stair tread and a riser?
The tread is the horizontal board that you step on with your foot. The riser is the vertical board that runs perpendicular to the treads, creating the height of the step.
Are open risers permitted by modern building codes?
Yes, open risers are allowed, but many local codes require that the openings be small enough that a four-inch sphere cannot pass through, preventing small children from falling.
