what is involved in moving pipes?

We are renovating an upstairs room, turning it into a bathroom, which means bringing in a sewer pipe either from the floor below or the bathroom next door. My contractor says this requires a permit, which requires an architect to sign off on the job, which could add a couple thousand dollars to the job. Does this sound right? Will an architect do something small like this, and how is the fee calculated? Any tips?
