The tools tell you the numbers. The guides and the advisory call tell you exactly how to use them, and how to hold a contractor to them.

Build Advisor CA provides independent, pre-construction advisory and educational guidance for California homeowners. We are not licensed contractors, architects, engineers, attorneys, or financial advisors, and nothing in these tools is a bid, a quote, a loan offer, or a project-specific estimate. All figures are directional and vary by scope, site conditions, city, finish selections, and market timing. Verify costs, permits, financing, and contracts with the appropriate licensed professional and your local building department before making decisions.
