What is the minimum lighting and electrical requirement for a habitable room?

• A. Two outlets
• B. One permanent light fixture only
• C. Four outlets
• D. Two outlets or one outlet and one permanent light fixture

Answer: (D)

A habitable room must have both a lighting source and adequate electrical outlets. The minimum is satisfied by either two outlets, or one outlet combined with a permanently installed light fixture. This ensures the space can be lit and has access to power for typical use.

Two outlets alone do not provide lighting, and a single permanent light fixture alone does not give convenient power outlets. Four outlets meet the power need but still lack a fixed lighting source. Therefore, the option that best fits the minimum is having two outlets or one outlet with a permanent light fixture.
