Once the Authority Having Jurisdiction determines a commercial building requires emergency lighting fixtures / exit signs, what NFPA document is used to determine exactly which rooms, etc. they are to be installed in? I searched NFPA 101 - Life Safety Code and could not find the information.

Usually, it is the path of egress and it would also include lighting outside of the exterior doors.

I can't find my antique copy of NFPA 101 but it might not be the code being enforced. You should ask your AHJ which code this requirement comes from. Most inspectors will also be willing to tell you what the specific requirements are.

Generally, from what little I know on the subject, the path of egress must be illuminated to 1fc average with no point being less than .1fc Most manufacturers or their agencies would be willing to do this layout for you. Some catalogs show specific spacings & mounting heights to achieve the 1fc.

Good luck

Few things are harder to put up with than the annoyance of a good example.

NFPA 101
NFPA 101 does address path of egress as you mentioned Tom. For an office building for example, do restrooms, conference rooms, lunchrooms, smaller offices etc. require emergency lighting. I was just wondering if there was another NFPA Document that would address this. I suppose type of occupancy and room size among other things would enter into the equation.
