Question 3-Way Switch

My house has 2 three-way switches on a separate circuit. Is it code that the kind of switches must be on its own circuit? I am thinking of wiring a bathfan using that circuit but just wonder if any problem? Thx.

There is no code dictating what you have found.

However, make sure that there really is nothing else on the circuit.

And be aware that among the two switch boxes and the fixture box, you can extend power from only one of them, and you won't know which one until you analyze the current wiring.

Also be aware that although there is no blanket restriction evident based on what you've said so far, there are a number of possible restrictions based on what you haven't said so far. For example, you can't extend the circuit if ungrounded. And you can't extend the circuit if it controls receptacles in certain rooms. And if the switches control an appliance, you also may not be able to extend the circuit. The details may be quite significant.
