Is a light fixture required within 25 feet of a roof top A/C unit?
FWIW the gas codes (at least around me) require a light at gas fired equipment.
I think you'll find that the gas code (NFPA 54 or CMR 248) require a light at the roof access when there is gas equipment on the roof. But this is often misinterpretted as requiring a light at the equipment.
That could be it.
I just know we have had to install them to get final inspection regardless of the fact they were not called for on the prints.

Great cite! I was not aware of such a requirement, and I doubt I've ever seen such a light on a rooftop.
As I see it, such a light is a great 'add on' or 'value added' feature. Would you place in on the outside (as in the pic), or within the compartment you need to open? Would you add a timer, or other means to ensure that it doesn't stay on unnecessarily?
I wonder how accepted NFPA 54 is, or whether this requirement is shared by the ICC codes. I also wonder about the application of the requirement where your 'access' is by setting your ladder against the wall of the building.
Try 9.4.3.4I have reviewed (2012 to 2021) NFPA 54 and there is no 8.4.3.4. Am i missing something?
Thank you, I literally found it as I got the email notification of your response.Try 9.4.3.4
And it’s always burned out! LOL!I think you'll find that the gas code (NFPA 54 or CMR 248) require a light at the roof access when there is gas equipment on the roof. But this is often misinterpretted as requiring a light at the equipment.
