Contractors who do this most

Rankings reflect permits where the firm is listed as contractor on DataSF building permit records, classified into categories from the permit's work description. Declared costs are the applicant's estimate at filing and often understate final project cost. A ranking isn't a recommendation, and we don't check licenses, bonds or insurance. Always verify the license at cslb.ca.gov, ask for references and proof of insurance, and get multiple bids. Methodology.
