What makes up the number

Hold this separate, on top

A 15-20% contingency for what is found once demo opens the walls (use 20% for pre-1985 homes). Do not spend it on upgrades.

Now pressure-test it against a real bid.

A number is only useful if you know how to hold a contractor to it. That is exactly what the advisory call and the guides are for.

Build Advisor CA provides independent, pre-construction advisory and educational guidance based on field experience advising California homeowners. We are not licensed contractors, architects, engineers, attorneys, or financial advisors, and nothing here is a bid, a quote, or a project-specific estimate. Cost ranges and the breakdown are directional and vary by scope, site conditions, city, finish selections, and market timing. Permit and city fees in particular vary widely by jurisdiction. Verify costs, permits, and contracts with the appropriate licensed professional and your local building department before making decisions.
