Frequently Asked Questions
Are these light-level targets a building code requirement?
No — they're commonly-cited general guidelines, not an electrical or building-code requirement. Check local code for anything safety-related.
What if my room has more than one type of activity (e.g. a kitchen with a dining area)?
Calculate each zone separately using its own room type, since a dining area needs less light than a food-prep counter.
