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.

Questions about hiring in Marin County

How many licensed general contractors are based in Marin County?

1,445 active B and B-2 licenses list Marin County as the business city in CSLB's records dated Oct 16, 2026. We list 1,248 of them; the other 197 have no bond on file or hold a specialty-trade license. Each card's "Verify on CSLB" link opens that license's live record.

Which license does a home remodel need?

A B (General Building) license can take a prime contract that involves two or more unrelated trades other than framing or carpentry. A B-2 (Residential Remodeling) license covers remodels of an existing wood-frame house with three or more unrelated trades, and it can't be used for additions, structural work or new homes.

How much can a contractor ask for as a down payment?

In California, a down payment on a home improvement contract is capped at $1,000 or 10% of the contract price, whichever is less.

Do I need a licensed contractor for a small job?

Work under $1,000 in total that needs no building permit is exempt from licensing. The exemption doesn't apply to someone who advertises as a contractor, has employees, or splits a job to stay under the limit.

What does "exempt" mean under workers' comp on a card?

The contractor told CSLB it has no employees. Until January 1, 2028, a B contractor with no employees can legally file that exemption. Ask whether anyone besides the owner will work on your property.

Where do I get a building permit in Marin County?

Permits are handled by County of Marin Community Development Agency, Building and Safety Division; the link is in "Before you hire" above. Ask your contractor who will pull the permit and have it in the contract.
