How many wall switch-controlled lighting outlets are required in every habitable room?

In every habitable room, the requirement is to have at least one wall switch-controlled lighting outlet. This is fundamental for providing adequate lighting that can be easily operated from a convenient location, enhancing both the functionality and safety of the living space. The presence of a wall switch-controlled outlet ensures that occupants do not have to rely solely on portable lighting solutions, which may be less reliable and can contribute to trip hazards if not properly managed.

This requirement aligns with building codes aimed at promoting safety and accessibility within residential settings. It establishes a baseline for lighting fixtures that can significantly impact the comfort and usability of a room, serving the needs of occupants effectively. Furthermore, the standard of having at least one wall switch-controlled outlet is a common practice in electrical design to facilitate ease of use and to set a minimum environmental standard for habitability.
