What does the National Electrical Code (NEC) say about lighting in habitable rooms?

The National Electrical Code (NEC) specifies that a minimum of one lighting outlet is required in habitable rooms. This requirement is in place to ensure that there is adequate lighting for safety, visibility, and general use in living spaces. Habitable rooms include areas such as living rooms, bedrooms, and dining rooms, where occupants spend significant amounts of time and need sufficient illumination.

By mandating at least one lighting outlet, the NEC promotes proper lighting practices that can help prevent accidents and improve the comfort and functionality of the space. The code does not specify the type of lighting to be used, which allows for flexibility; therefore, options such as ceiling fans or recessed lighting are not prescribed or limited, which is why those options do not align with the NEC’s requirements.

This attention to lighting demonstrates the NEC's focus on both safety and practical usage within residential environments.
