Getting the C-15 License for flooring offers the opportunity for incredible income potential within the construction industry.

The installation of wood floors, carpets, and laminates are critical services and almost always required within virtually all construction projects.

Commercial flooring jobs can be incredibly lucrative especially if you offer a one-stop service for clients to choose materials, have their previous floor removed and a new one installed.  

This article will provide you with every single detail you need to know about how to get your C15 license, requirements, the flooring license test, and even how to fill out the application.

What is a C-15 Flooring Contractor?

A flooring and floor covering contractor prepares any surface for the installation of flooring and floor coverings and installs carpet, resilient sheet goods, resilient tile, wood floors and flooring (including the finishing and repairing thereof), and any other materials established as flooring and floor covering material, except ceramic tile.

C-15 license and the General Contractor

They may also be subcontracted by a General Contractor who has placed a bid on a project that includes flooring. The flooring construction portion would be overseen by the General Contractor.

What is the CSLB?

The Contractors State License Board (CSLB) is the governing body for all contractors in the state of California.

Their sole responsibility is to protect the consumer public and ensure that anyone charging over $500 for construction services is qualified and registered with the state of California.

The C-15 License is issued to flooring contractors by the CSLB.

The CSLB administers applications, exams, and maintains a database of all active and inactive contractor license numbers which are public domain.

How to get the C-15 License

To get a C-15 license in California, you must prove a minimum of 4 years of journeyman level experience and pass a two-part state exam with the Contractor State License Board.

To get an exam date you must meet the following requirements:

  • Be at least 18 years of age
  • check Have a valid Driver's License or USA Issued Identification
  • Have a Social Security or ITIN #
  • Not Currently be on probation or parole

You must also have:

  • 4 Years Journey Level Experience
  • A Qualifying Individual to sign off on your experience
  • A way to prove your experience if the state asks for documentation

What is Journey Level Experience?

Journeyman level experience means that you have worked unsupervised full time for a flooring company, or for a contractor that holds the C-15 License.

  • A journeyman can perform all of the duties associated with his or her trade.

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. 

Signature of a Qualifying Individual

The following people may be used as Qualifying Individuals to sign off on your experience when applying for the C-15 license:

  • Licensed General Contractor
  • C-15 License Holder
  • Fellow Employee (within the last 10 years)
  • check Former Supervisor (within the last 10 years)
  • check Business Associate
  • check Fellow Journeyman
  • check Union Representative

Filling out the C-15 License Application

Your Qualifying Individual will also need to provide a brief but detailed description of your knowledge and skillset.

The way this description is written will be critical to whether or not your application is accepted. For example:

“Ed is a great guy and has a lot of experience installing carpets…” will not be accepted by the CSLB.

 The CSLB will want to see something more like:

“Greg has installed, finished and repaired vinyl, wood, linoleum, and resilient tile floors”, etc.

Proving your work experience for the C-15 License

You must be prepared to submit documentation supporting the experience you claim to have. The Contractors State License Board gives you a few ways that you can prove your experience.

  • 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.

C-15 License Application, Fees, 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 somewhere 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-15 License. I have personally helped guys with all types of criminal records obtain multiple licenses.

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 are primarily concerned with criminal charges associated with:

Fraud, Forgery, and Embezzlement.
