CSLB's public data lists 51 limited specialty contractors with a mailing address in Napa, and 50 of them (98%) show a Clear primary status.

29.4% report a workers' comp exemption, 6.8 points lower than the statewide figure for limited specialty contractors (36.2%), so many of these businesses say they have no employees. The share with a suspension (2%) is close to the Napa County rate for the same license (2.8%).

0 of these licenses are less than a year old, while 66.7% have been held for 10 years or more. The median is 18.6 years.

C-61 licenses are always paired with a D-subcategory that names the specific trade, so check the "D" code on each profile. See the C-61 Limited Specialty guide for what the license covers.

How to check a limited specialty contractor's license in Napa

  1. Open the limited specialty contractor's profile from the table below (or search Napa listings by name). Check that C-61 appears among its classifications and that the primary status reads Clear. What C-61 covers.
  2. Confirm it live with CSLB's Instant License Check. Statuses change between our weekly refreshes, especially workers' comp and bond suspensions.
  3. Ask for the pocket license and a photo ID and match the name to your contract. Work of $1,000 or more needs a license (the $1,000 rule), and a down payment can't exceed $1,000 or 10% (down payment rules).
