Bathroom remodel contractors in Marin County, CA
No contractors are listed for bathroom work in Marin County yet. CSLB license data dated Oct 16, 2026.
Which license do you need?
B or B-2 license required. A B-2 can take a bathroom job in an existing wood-frame house when the contract covers 3 or more unrelated trades and nothing structural changes: no load-bearing walls, foundations or roof structure. A structural plan needs a B.
Do you need a permit?
Check with Marin County first. In unincorporated Marin, a non-structural kitchen or bath remodel up to 400 sq ft gets a quick online "minor improvement" permit with no plans sent in; the plans are checked at the job site.

California rules for your contract
A down payment on a home improvement contract can't be more than $1,000 or 10% of the price, whichever is less. No progress payment can be more than the work done or materials delivered.

Work under $1,000 in total (labor and materials) that needs no building permit doesn't require a license. The exemption doesn't apply if the person advertises as a contractor, has employees, or splits a job to stay under the limit.

Every licensed contractor must keep a $25,000 contractor's bond on file with CSLB. That has been the amount since January 1, 2023.

A contractor with employees must carry workers' comp. Until 2028, a B contractor with no employees can legally file an exemption, so check which one yours did. From January 1, 2028, a workers' comp certificate is required for every license.

How this list is built
We have no city permit file for Marin County yet, so a contractor is listed only if it confirmed bathroom work to us. A contractor is listed only with evidence for bathroom work: a permit record whose description matches, or a source the contractor gave us.
License class, status, dates, bond and workers' comp come from CSLB's public data files: Master file Oct 16, 2026, workers' comp file Oct 17, 2026, processed Oct 18, 2026. Each card links to that license's live CSLB record. Full method.
