It really depends on the type of finishes one uses. But on average, I would say in this county approximately
$350 (+-) per sq ft. There are high end homes in this county that far exceed that price (Ross, Kentfield, Tiburon and even Mill Valley) - one can climb to $500 - $600 per sq ft.
Hope that helps, we have a team of experts to assist any home buyer/seller to evaluate remodeling aspects of a project.
