We use public records to help you make a shortlist. They show what a contractor has filed and where they have worked in Marin County (unincorporated). They can't tell you whether someone will be right for your home.
California contractors doing jobs of $1,000 or more must hold a CSLB license.
88% of the 1,596 firms on the Marin County (unincorporated) permit file match an active license in the California CSLB license master file, using the license number typed on the permit when it fits the firm, otherwise matched by business name. Our match can miss a firm that files under another name, so a missing match is a reason to check, not a finding.

The middle value recorded on this contractor's matching permits. It's a permit value, not a quote or the final price. Ask for a written estimate.
Matching Marin County (unincorporated) permits in the most recent year of our data. It shows recent recorded activity here, not every job the company did.
For contractors with at least 5 permits a year or more old, the share with an approved final inspection. A permit can stay open because of paperwork or timing, so this isn't a workmanship grade.
How long their permits take from issue to the approved final inspection, compared with other Marin contractors in the trade. Shown for firms with 10+ permits.
Matched by name against the California CSLB license master file, using the license number typed on the permit when it fits the firm, otherwise matched by business name. Name matching can miss a license, so always check the number yourself.
About the ranking: The score combines how much of this exact work a contractor has on record, how often their older permits reached completion (where we can measure it), how well their usual job size matches your budget, how recently they've been active, and how much of their work is near you. A measure we can't calculate is left out rather than guessed, and a thin record pulls the score toward the middle. A contractor whose matched license has a problem is listed after everyone else. You set the weights with the sliders on every list.
Marin County (unincorporated) specifics: These are County permits for unincorporated Marin only; the county's 11 cities and towns issue their own permits and aren't included. The County file has no status field, so completion comes from approved final inspections. Over-the-counter Minor Improvement permits, used for nearly all solar and many kitchen and bath jobs, never appear in the inspection file, so they count toward a firm's volume and cost but not its completion or speed: solar shows no completion rate or speed, and remodel completion rests on the two-thirds of remodel permits that are tracked. Remodel shows no speed because no firm reaches the threshold, and additions and ADUs show counts and typical cost only. Home values are Proposition 13 assessed values, so the kind of homes a contractor works on and the price comparison are rougher than in most places. Marin is a small market, so many firms have too few permits for completion, speed or a price comparison. Locations are by ZIP code.
