Need some help with a switch requirement.
Is there any code reference for where you have to mount the switch to control the light/receptacle for a room?
If I am not mistaken, the NEC goes as far as to say you need to have one for each room, but does not require it be mounted in any given space within, or even outside of the room.

Bob,
I was asked by a fellow inspector about the requirements for lighting/switched receptacles in rooms. To my knowledge, I only know of the requirement that it has to be there, none about the location of the switch.
I was pretty certain that the NEC only addresses the fact that every room needs one, not where the switch is located. Basically that means if you have a 25 foot hallway with three rooms off that hallway, you could have the lighting switches for all three rooms located at the beginning of the hallway, regardless of where in the hallway the rooms are positioned.
Come to think of it, I don't even think there is a requirement for them to be controlled by switches, they could be controlled by breakers, as long as you can turn them on and off from where ever the "switch" is located.

Staying with the NEC references here is what the section says.
Quote:
210.70 Lighting Outlets Required.

(A) Dwelling Units. In dwelling units, lighting outlets shall be installed in accordance with 210.70(A)(1), (2), and (3).
(1) Habitable Rooms. At least one wall switch-controlled lighting outlet shall be installed in every habitable room and bathroom.
Exception No. 1: In other than kitchens and bathrooms, one or more receptacles controlled by a wall switch shall be permitted in lieu of lighting outlets.
Exception No. 2: Lighting outlets shall be permitted to be controlled by occupancy sensors that are (1) in addition to wall switches or (2) located at a customary wall switch location and equipped with a manual override that will allow the sensor to function as a wall switch.
(2) Additional Locations. Additional lighting outlets shall be installed in accordance with (a), (b), and (c).
(a)At least one wall switch-controlled lighting outlet shall be installed in hallways, stairways, attached garages, and detached garages with electric power.
(b)For dwelling units, attached garages, and detached garages with electric power, at least one wall switch?controlled lighting outlet shall be installed to provide illumination on the exterior side of outdoor entrances or exits with grade level access. A vehicle door in a garage shall not be considered as an outdoor entrance or exit.
(c)Where one or more lighting outlet(s) are installed for interior stairways, there shall be a wall switch at each floor level, and landing level that includes an entry way, to control the lighting outlet(s) where the stairway between floor levels has six risers or more.
Exception to (a), (b), and (c): In hallways, stairways, and at outdoor entrances, remote, central, or automatic control of lighting shall be permitted.
(3) Storage or Equipment Spaces. For attics, underfloor spaces, utility rooms, and basements, at least one lighting outlet containing a switch or controlled by a wall switch shall be installed where these spaces are used for storage or contain equipment requiring servicing. At least one point of control shall be at the usual point of entry to these spaces. The lighting outlet shall be provided at or near the equipment requiring servicing.
(B) Guest Rooms. At least one wall switch?controlled lighting outlet or wall switch?controlled receptacle shall be installed in guest rooms in hotels, motels, or similar occupancies.
A breaker would not qualify as a wall switch, however you could put the wall switch any where you want in many of the sections[/quote]

Does the NEC differentiate between Residential vs. Commercial & Institutional Properties?
"Dwelling Units" or "Other than Dwelling Units. 
The code section I posted above applies to "Dwelling Units"
To the NEC a dwelling unit may be a single family home or a 50 floor Hi rise hotel.
Here is the 2002 NEC definition of dwelling unit.
Quote:
Dwelling Unit. One or more rooms for the use of one or more persons as a housekeeping unit with space for eating, living, and sleeping, and permanent provisions for cooking and sanitation.
Some hotel rooms, fire stations, apartment buildings, retirement homes could all be "Dwelling Units"
If the building is "Other Than Dwelling Units" there are almost no requirements for switches or receptacles.
You will not see a row of light switches on the way in the door of your local "Target, Walmart, Kmart etc.

Be careful I do not believe all breakers are designed to be used as switches. I think ( I could be corrected )sq D are the only ones that are approved to be used as a disconnect . The rest are for isolation only.

That is per code now the manufacturer instalation instruction may something different and they should always be followed first.
