The ideal tread run for stairs is 12". The wider the tread run, the better it is. The minimum requirement is 9"; however, many people trip on stairs that have such short tread runs. Many municipalities have code requirements associated with tread runs. Even though home inspectors are not required to inspect to code, it is appropriate to provide this information to clients so they are aware of the potential safety issues.
