Light Switches in Existing Commercial Building

[Mule]

Discussion going on here between me and the inspectors. One of my inspectors came in and said that when he went in to perform an inspection on a lease space and there wasn't a light switch by the front door to turn on the lights.

I commented...where in the NEC does it state that you need a light switch at the front door to turn on the lights? He came up with 210.70. My comment back was most of 210.70 is for residential installations. Subsection C is the only section that specifies anything other than dwellings and that section doesn't have anything to do with what we are talking about.

Is it out there somewhere???? Probably the energy code BUT this is an existing building and is not having any renovations being performed.

How about you experts! Is there a code section requiring a light switch by the door? Or even in the same room??

Thanks in advance!

Even in a residence a switch is not required by the door. Illumination is required not a switch.

 

[brudgers]

I doubt it. Would you want one in a bank lobby so that the robbers can turn the lights off easily?

I wonder how your inspector writes up a motion switch in a bathroom? Ask them how long they have to sit there without moving before they can test that switch.

I wonder how your inspector writes up a motion switch in a bathroom? Good one, Papio! My thoughts too? MacGoober puts two wires together!

Breaker box in the back of the store, real common.

Now that's a good one!!! DON'T MOVE OR BREATH!! You're turning blue....splat! Maybe it will go off now!

The panel WAS in the back of the store.... Inspector said well what if they trip over something going to the breaker box?

 

[Mule]

northstar,

New buildings yes, this building has been there quite some time now. Maybe his brain is on new requirements...

Mule,

Is a "new" [ different than the former Occ. Group ] Occupancy Group moving in

to the tenant space in question?

As I understand it, if the existing space has lighting that is controlled by a

functional / compliant circuit breaker; in an interior elec. panel, then they

are compliant!.....A switch does not have to be located in that space, for

existing applications.

How would that change things unless there is a local amendment.

 

[gbhammer]

If there is no natural illumination, and the switch is in another room, then there better be night lighting if some sort in the event that the room is occupied and some one in some other room can turn off the lights. Unless its exisiting an no alterations have been made.

There is no requirement for that in the NEC and have never heard that there was one in the building code but there may be for commercial jobs.

No, same tenant, same use, it was a name change that caused the inspector to go by. We always require a inspection on name changes and tenant change outs per ordinance.

Now if the use changes that's a different story.

Okay but that does not state that the switch must be in the room. Sure if new occupants come in they can enforce some changes but this is compliant IMO.

Mule,

I agree on the "if the use changes that's a different story" thingy,

...unfortunately [ here ] the "powers-that-be" do not!

I agree!...Since I do not know all of the nuances involved [ with Mule's application ],I was merely providing information to consider......It's kinda like some of the contractors

tell me around here, " ...you don't know what you're going to find until you open up the

walls and actually see".

Nothing in those sections requires a switch at the door. A breaker in the panel would suffice.

There is nothing in the NEC that requires a switch at a door.

Raider we don't require a switch at the door we simply require that if the space does not meet the level of required illumination the moment it is occupied then it is in violation of the code.

 

[gbhammer]

If you have to occupy a room and then walk across a dark room to turn the light on you are in violation of the building code.

 

[Msradell]

Raider we don't require a switch at the door we simply require that if the space does not meet the level of required illumination the moment it is occupied then it is in violation of the code.

I truly hope your code isn't written quite like that. If it was I think the only way to truly meet the requirement would be with a motion detector or a switch that the door tripped. Saying that must be illuminated the moment it is occupied is extremely concise and in my view would mean instantaneously, so they get obviously is not what happened even if you just considered the delay time to turn on the switch.

I think this entire discussion depends on where the employees enter the business. Normally that is from the back so that is where the switches should be.

 

[gbhammer]

There is most likely going to be some natural illumination from the open door way in order to step over the threshould and still be compliant. The point is that without natural or artifical (night lighting) you are creating a hazard/code violation if you have rooms that are not illuminated while being occupied even if for just the time it takes to walk across the room to a panel board, and to mees with a panel baord in the dark is even more dangerous.

 

[Builder Bob]

What was required when the building was built???? The concept of the fire codes is to maintain the same level of safety as was required when the building was built-

For example....

Old building built in the 80's under the Standard Building Code (Standard Fire Prevention Code) did not require emergency illumination at exit discharge or when natural illumination was adequate. Today, this building remains the same as it did all those years ago... except, when new alterations or a partial change of use occurs, it has to be brought up to current code compliance in the work areas affected.
