I am a registered builder in New Jersey who has a daughter living in Palo Alto, CA. She is looking to demolish her two bedroom cottage and construct an upscale stucco sided home with a basement. I am trying to pin down some of the subcontractor costs in California. The quotes she is getting from her architect are out of sight. For example, around here, sheetrock (including the finishing) is quoted at $8-$10 per board (4×12). Out there, she is getting a cost estimate at $84 per board.
Is there some general reference source I can contact in California to get a profile on building costs for various subcontractors.
