>This is definitely false for new code, sorry.

I'm not reading your link at 1am. Tell me what I wrote that's wrong. I'm aware that old installs are grandfathered in, I stated that much. Updating your out of date electrical isn't required when doing fixture replacement. I won't argue that it shouldn't be brought up to code, because it should be, but nothing I stated is wrong.

I say a waste of a circuit because a bathroom fan might use 60 watts. Why on earth would you use an entire circuit for the same current draw as an incandescent light bulb? The only time you'd want to run a new circuit here is if the entire bathroom is on a single circuit so the fan and countertop outlets are sharing the same circuit. But there is ZERO reason to separate a fan from your lighting. Either update your LEDs or fan.

Additionally, lots of houses have smaller panels, especially older houses where the same circuit powers the bathroom and additional areas. Newer houses still run out of space on a 200A 30 space panel.

Edit: Figuring maybe you're talking about lighting and outlets being required to be on separate circuits in new code.

210.11(C)(3) Bathroom Branch Circuits. In addition to the number of branch circuits required by other parts of this section, one or more 120-volt, 20-ampere branch circuit shall be provided to supply bathroom(s) receptacle outlet(s) required by 210.52(D) and any countertop and similar work surface receptacle outlets. Such circuits shall have no other outlets.

Exception: Where the 20-ampere circuit supplies a single bathroom, outlets for other equipment within the same bathroom shall be permitted to be supplied in accordance with 210.23(A)(1) and (A)(2).

that’s not the wording of the code. Exception: Where the 20-ampere circuit supplies a single bathroom, outlets for other equipment within the same bathroom shall be permitted to be supplied in accordance with 210.23(A)(1) and (A)(2).

OUTLETS can be shared, OUTLETS is the key word you changed.

Good lord. I didn't change anything. YOU are misunderstanding what the definition of 'outlet' is in the NEC.

NEC Article 100 defines an “Outlet” as a point on the wiring system at which current is taken to supply utilization equipment. The term “outlet” is often misused to refer to receptacles. Receptacle outlets are only one type of outlet. Other types of outlets include lighting outlets, appliance outlets, smoke alarm outlets, equipment outlets and so on.

A lighting outlet is an outlet intended for the direct connection of a lampholder, a luminaire or a pendant cord terminating in a lampholder. Luminaires can be ceiling-, wall- or even floor-mounted (See Figure 2). While the wiring for lighting outlets can terminate in outlet boxes and in other boxes under certain conditions, it can also terminate in junction boxes of luminaires.

So, in short, just because you don't understand what 'outlet' means in the context of the NEC, doesn't make what I wrote wrong. If you're still adamant, go ask someone in /r/electricians. I've been through hundreds of inspections, have you?
