Wood Stairway Handrail Code Violation
Don't get me wrong, this
wood handrail can easily be gripped onto by most people, the problem is that
it probably won't pass current building codes.
The illustration below will provide you with a better example of what most current building codes require, but keep in mind the stairway could've been built years before these codes became active. For example, current building codes also require a minimum of 4 inches between stairway balusters and these almost look like they're 12 inches.
Remember to check with your local Building Department to validate any information on this website. Building codes change and some Building Department officials actually interpret this information in a variety of different ways, leading to mass confusion among stair builders.
