Estimated Cost of Home Repairs in Northern California

Home inspectors in the State of California should not perform repairs. We do not include price estimates in our property inspection reports, as it is considered a conflict of interest.

All Bay Home Inspection, Inc. has developed this list to serve as a guideline and to provide estimates for some common items.

The referenced costs are for a typical 2000 Sq. Ft. or less house in Northern California. Site access and other factors could increase cost substantially.

Always obtain three signed bids from a Contractor Licensed by The State of California.
