Narrative:

Aircraft landed on runway 28 on a clear but dark night. I instructed pilot to 'turn right on taxiway A4; right on taxiway a; taxi to the ramp.' the pilot made the two right turns; but then turned left onto taxiway C (a non-movement area) which is the entrance to the general aviation ramp/FBO parking. This is about 1000 ft short of the entrance to the air carrier ramp and required the aircraft to make a 180 degree turn to re-enter alpha taxiway. This is not the first time I have seen this happen.callback conversation with reporter revealed the following information: reporter stated he has seen two aircraft this month turn into the non-movement area on taxiway C. He is not aware of any other controllers observing the problem. He feels airport signs could be improved.
