I didn't see this posted, but I might have missed it.
Use a 2 pole switch. Split or tee off the circuit before the switch. One side to the switch and then to the light. The other side to GFCI recep, then back to other pole on switch and then to fan. Kind involved and complicated, but it will work.

I agree SANDSNOW and it's really not that difficult. Use a two pole toggle switch or a two pole timer switch. Brilliant! Simply brilliant!!!

Are 2 poles switching GFCI, light, & fan?

One pole switches the light
The other pole switches the fan. That pole of the switch is on the load side of GFCI

Ahh, I see. This circuit shares the light line side of GFCI, so it won't interfere with (trip) the GFCI monitored fan.

Larry, thats twice I fell off the turnup truck today. The first bump was landing in your teritory this morning, at KAISER Sand Canyon. I better tell them to prepare some cookies & milk.

This must be a local or state code. I couldn't find anything in the 2005 NEC that says fans in dwelling unit showers have to be GFCI protected. Unless the fan has an integral receptacle, I think it's legal to have it on a non-GFCI-protected circuit.

Jeff -this is a listing requirement of almost all bathroom fans. (Guess how I learned THAT little lesson...)

I have never seen a bath fan without an integeral, 2 wire receptacle. This is so the fan motor may be replaced without removing the housing. Of course, by the time the motor goes bad, the model is usually out of production and you can't get a motor that fits the original housing. Also, the only fans I find are either not rated for over tub/ in shower install or they are only listed for such installs when GFCI protected.

Matt, That 'receptacle' is not a receptacle to the NEC.

If it was it would have to be a grounding type and it would have to be rated at least 15 amps.

Of course, your too dangerous, without something stronger to dull that sharpness.

Too bad your not elected, like other public servants, so local jobsites can legally operate with parades of beer wagons and topless menchens, as a political campaign.

I got ya covered Larry. Anything you want.

Re: Bathroom Lights & GFIs

You guys lost me when you got to the 20amp receptacle requirement for the bathroom. Could someone please post the code reference for that.

Re: Bathroom Lights & GFIs

From the UL "White Book"

FANS, ELECTRIC (GPWV)

USE AND INSTALLATION
. . .
This category covers fans and blowers intended to move air for the purpose of air circulation or ventilation.
. . .
Fans intended to be mounted over tubs or showers have been evaluated for such purposes and are marked ??Acceptable for use over a bathtub or shower when installed in a GFCI protected branch circuit.??
. . .

And from the 2005 NEC

210.11 Branch Circuits Required

(C) Dwelling Units

(3) Bathroom Branch Circuits In addition to the number of branch circuits required by other parts of this section, at least one 20-ampere branch circuit shall be provided to supply bathroom receptacle outlet(s). 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).

I was aware of the required 20 amp circuit, but that still dosen't require a 20 amp receptacle as far as I can tell.

You are right. However, if you supply only one bathroom from the circuit, and if you supply only one receptacle (and no other loads) in that bathroom, then 210.21(B)(1) requires that one to be a 20 amp receptacle. On the other hand, if a single circuit supplies receptacles in more than one bathroom, or if it supplies two receptacles in the same bathroom, or if it supplies a receptacle and other outlets in the same bathroom, then the receptacles can be rated at 15 amps.

Also, a duplex receptacle is two receptacles.
