We have a military project in the US, so the project is mandated to be compliant with UFC criteria.
We are required to locate an LOC (Local Operating Console) within 200-ft of all portions of a building.
Is exiting the building, and re-entering, to access an LOC permissible?
If we have exterior-only mechanical rooms, electrical rooms, or maintenance bays (which each only access the outside), then at what point would an LOC be required in each of these spaces?
I'm not trying to be facetious or dramatic, just looking for outside opinion on working through a gray area in my mind.

Typically LOCs are not required to cover Equipment Rooms. Recommend getting clarification from the DFPE for your project.

It has been our experience that the intent is not to provide LOC access within mechanical rooms and areas only accessible from the exterior.

Per UFC 4-021-01 Section 4-5.1, LOC shall not be provided in a locked room or closet. Exterior access mechanical and electrical rooms would fall within this requirement as they are almost always locked and accessible to authorized personnel only. These areas could also be seen as normally unoccupied, which I would argue does not meet the intent of the LOC requirements per UFC. A maintenance bay, even if exterior access only and since normally occupied, would require a LOC for the occupants of the bay area, unless directed otherwise by the AHJ.

My understanding is the spaces you mentioned would be considered low occupancy and would not require an LOC.

I think K Kyes has nailed it with the reference to 4-021-01 Section 4-5.1. The thing I would add is the statement in that section that states "Provide a LOC to allow emergency response forces and BUILDING OCCUPANTS to access the MNS..." Building occupants don't typically have access to Mech/Elec/Etc spaces, so that in combination with not locating a LOC inside a locked room, this would dictate they are not required in these spaces.
