Default 3 way switches-Building Code

Does the Canadian building code require a switch at every entrance of a room.

Installing lights in a room that has two entrances and trying to figure out if a switch is needed at each entrance.

Common sense and what I probably will do is a switch at each entrance but am wondering if it is a code requirement.

30-502 requires a luminaire to be controled by a switch in pretty much every room.

Three-ways not a code requirement except at stairways... 30-504

Cheers

This is a commercial space, that rule is for residential occupancy.

Neither the building code nor electrical code require switches at every entrance to a room for residential or commercial.

I am pretty good at a lot of things... but mind reading is not one of them I guess :-)

Commercial / industrial is open season. I have heard however some AHJ have related the installation of switches as a requirement for the safe ingress and egress to a space if there is not any permanent illuminated fixtures (night lights).

In the NEC land , there is no requirement that the switch for lighting a room be even located in that room. Strictly speaking the switch for the lighting could be on another floor on the opposite side of the building and it would still meet code.
Not a very good idea obviously, but still meets code.

In my apprentice days I did a fair amount of lighting for grocery stores and other larger retail stores...

Typically we would have a separate lighting panel on a 3-pole contactor controlled by a single pole switch. Of course that switch would control all the lights in the entire space, retail area, stock room, loading bays, offices, mechanical, etc.

While electricity was a lot less expensive back then, it was either all on or all off and the switch was in some "hidden" location so it did not get turned off accidently.

I think today with the cost of electricity it makes more sense to spend a bit extra and control individual spaces with occupancy sensors.

Cheers

Here is quote from the 2015 hand book: The design of the switch locations for luminaires should not require the occupant to travel to the other end of the hallway or room to operate the switch. Similarly, where an area has multiple entrances, the use of 3- and 4-way switches enables the luminaires to operate independently at each entrance without the occupant having to move around in the dark looking for the switch. Like you said, better safe than sorry!!

People have become so lazy that they cannot get off their ass and walk to a switch. They wanna be able to turn it on and off with their stupid smart phone.

There is an epidemic of obesity now. The NEC should have a code that says you have to go 25 feet minimum to turn on a light.
