I am wiring a renovated interior room that will not be used as a kitchen, bathroom, utlity room and does not have an exterior-access door. This room has 3 doors. I believe I am required by code to have a light switch at every door - is this correct? Thanks!

No, multiple switches are not required by Code for this room.

Only stairways required multiple switches on each level.

Of, course, mutiple switches will be a good idea for your situation.

One occupancy sensor may help to reducde the amount of switch locations.

tkrussell - Thank you! I suspect that I will have to wire it with a 4-way anyway since the wife will weigh-in on this and I know what the answer will be - and like you say, would be good idea for this situation.
