What is A C6 License?

The C-6 License is the classification required in the state of California for all contractors looking to bid on residential and commercial finish carpentry projects where the cost of labor and materials exceeds $500.

Projects may include: 

  • Chairs
  • Couches
  • Staircases
  • Doors and Tables
  • Shelvings
  • Stairs, Baseboards and Hang Windows

A cabinet, millwork and finish carpentry contractor makes cabinets, cases, sashes, doors, trims, nonbearing partitions and other items of "finish carpentry" by cutting, surfacing, joining, gluing and fabricating wood or other products to provide a functional surface.

This contractor also places, erects, and finishes such cabinets and millwork in structures. - CSLB.GOV

Functional cabinetry, tables, and chairs are found in virtually every residential home.

Finish Carpenters are often paid top dollar to produce customized pieces as well as common household wood products.

Duties Associated with the C-6 License

Finish carpentry contractors engage in a wide range of projects. Some of their daily job site duties can include:

  • Using Glue and Mastics
  • Ordering Materials
  • Reading Blueprints
  • Inspection
  • Paint and Stain Finish Work

Finish Carpentry Subcontractor

A finish carpentry contractor holding the C-6 License may work directly with a client or homeowner to complete a very specific project.

However, they can also work with a General Contractor as part of a larger construction or remodel job. 

General Contractors may sub out the finish carpentry and millwork to a C-6 licensed contractor who has their own shop. 

The prime contractor ensures that the finish carpentry process is not only executed up to code but often times to the specific request of the client.

Journeyman level experience means that you have worked unsupervised full time for a construction company, a contractor that holds the C-6 License, or Union.

  • A journeyman finish carpenter can perform all of the duties associated with cabinet making, millwork and finish carpentry.

The CSLB will want to see four full-time years over the last ten years. The years do not need to be consecutive, but they do need to be four years in total.

Proving Your Work Experience for C-6 License

You must be prepared to submit documentation supporting the experience you claim to have.

The Contractors State License Board gives you many ways to prove your experience including:

  • Tax Returns
  • Check Stubs
  • Contracts
  • Material Order Invoices or Receipts

The CSLB  receives thousands of applications per month so there is a good chance they won’t document your experience but if you are one of the applicants that get reviewed you will need to be ready to submit something. 

The CSLB does not accept pictures of projects.

How to fill out the C-6 License Application

The person you choose to be your qualifying individual will need to write a detailed description of your knowledge and skillset.

The CSLB is strict on how this description has to be written. 

For example:

“Ricardo has done finish carpentry for many years”  will not be accepted

 The CSLB will want to see: 

"Ricardo has installed, erected and finished cabinets, cupboards, counters, stairs, baseboards trim, paint & stained, used glues and mastics" etc.

Application Processing, Time Frame and Criminal History

The time it takes to get your application processed and assigned a test date fluctuates throughout the year.

Typically you can expect:

  • 6-8 Week Application Processing Time
  • 3-4 Week wait for an Exam date

I have seen some situations where applicants got their test date sooner and some where they got their test date much later.

The most common reasons your application would get held up are:

  1. Time of year (processing time slows down during the holidays) 
  2. Criminal History 
  3. Proving Experience
  4. Mistakes on your application

Can you get a Contractors License with a Felony in California?

Having a criminal record in no way stops you from getting a C-6 License.

Thousands of contractors get licensed and bonded each year despite their criminal records.

The key is to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.

BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do fingerprinting. 

The CSLB handles criminal records on a case by case basis. Remember, their responsibility is to protect the public.

In my experience, they primarily concerned with criminal charges associated with:

  • Fraud
  • Embezzlement 
  • Forgery 

In the state of California, you are required to divulge any criminal charges when applying for any state license even if they have been expunged.

You will need to be prepared to submit anything they ask for regarding your criminal history.
