Are two light switches required for a long hallway?

Tuesday, August 24, 2021

The National Electrical Code requires at least one switched light fixture in a residential hallway [NEC 210.70(2)(1)]. There is no code standard for two switches on a long hallway. One electrician we know mentioned that he had heard that a second switch was required for hallways 10-feet and longer, but we suspect he was confusing it with another NEC requirement for at least one wall receptacle at hallways 10-feet or longer.

    Although not required, a switch at each end of a long hallway on a three-way circuit is a sensible thing to do. Also see our articles What is a three-way switch? and What is the code minimum height for a hallway ceiling? and What is the minimum width of a hallway? and How many electrical receptacle outlets are required in a hallway?
