Guess I should live in Mass.
Checked it out-if new install, then it is permissible-but not required.
I just would not want to be on toilet or in shower and lights go out just b/c the GFCI tripped for some reason.
To me, it's an inconvenience. I wire bathrooms where the home run goes to the switch box, power goes from here to GFCI and then onto other outlets and power to one side of the switch and the lighting switch leg to the other side. This way the lights are controlled only by the switch.
It's unpractical to take power to the outlets and THEN to the switch for lighting. I've never seen it done and will NEVER do it that way.
I only want other outlets to be slave to the GFCI.
To me, lighting is separate from power. It's the way I've done it for 20+ years.
