The International Residential code (2000 edition) section R303.4.1 states that "the control for activation of the required interior stairway lighting shall be accessible at the top and bottom of each stair without traversing any step of the stair."

To me, this contradicts the "six riser" rule in NEC 210.70.

How does your city call this?

More importantly, if someone were to get injured (falling down the stairs), would you as the electrician be accountalbe for following the NEC but not the IRC?
