A basement stairway has no light switch at the top and a single bare bulb at the bottom. This is:

Stairway lighting is a safety system, not an amenity, and the control location is the part that makes it work. A switch only at the bottom means the descent is made in the dark to reach it, which is precisely when tread edges cannot be judged. Stairs are among the most frequent sites of serious injury in a house, and basement stairs compound the risk with steeper rises, open risers and storage encroaching on the run. The generally recognized expectation is that stairways be illuminated and that the illumination be controllable from each floor level the stairway serves, so the user can light the path before stepping onto it. The inspector reports this as a safety concern and recommends correction; the number of treads does not remove the hazard.

A stairway should be lit before it is used, which requires a control at the point of entry. With the only switch at the bottom, the descent happens unlit, so the arrangement is reported as a safety concern rather than as a convenience issue.

Interior stairways are expected to be illuminated, with lighting controllable from each level the stairway serves so a user never has to travel the stairs in darkness to reach a switch. Home inspectors report stairway safety items — lighting, handrails, guards, uniform risers — as a recognized category.

Light Before You Step. If the switch is at the bottom, you walked down in the dark to reach it — the control belongs where the journey starts.

Inspectors under-report stairway items because they look minor. On the NHIE, stairway lighting, handrails and guards are treated as safety findings — pick the safety framing.

• •Treating stairway lighting as a convenience or efficiency item
• •Excusing the arrangement because the flight is short
• •Reporting the bare bulb as the defect while missing the switch location
