What is the maximum variation permitted in riser height over a flight of stairs?

1/8 inch
1/4 inch
3/8 inch
1/2 inch

The correct answer is: 3/8 inch

The maximum variation permitted in riser height over a flight of stairs is 3/8 inch. This measurement is crucial for maintaining safety and comfort in stair design. Uniform riser heights allow for consistent stair usage and help to minimize tripping hazards, especially for individuals who may have mobility or visual impairments. Ensuring that all risers are closely matched within this tolerance promotes compliance with building codes, which require accessibility and safety in residential construction. This standard also reflects best practices in construction, where small discrepancies can lead to larger safety concerns. By allowing a maximum difference of 3/8 inch, regulations strike a balance between practical construction methods and the need for safety in residential environments.
