Due to the nature of the trade, metal contractors typically work directly with businesses or clients looking to have customized jobs done.

In a construction setting, a General may hire a D-24 Metal Contractor specifically for their expertise or specialized equipment.

As a result, a general contractor oversees the project to completion and ensures that this phase of the work is executed correctly.

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. 

They ensure that anyone charging over $500 for construction services is qualified and registered with the state.

The C-61 / D-24  Metal contractor license is issued to contractors by the CSLB. 

D-24 Metal Products Contractor License Requirements

To get the metal products contractor license individuals must prove a minimum of 4 years journeyman level experience and pass a law exam.

To qualify for an exam date you must meet the the following requirements:

  • Be at least 18 years of age
  • Have a valid Driver's License or USA Issued Identification
  • Have a Social Security or ITIN #
  • check
    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 metal production company or someone that holds the D-24 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 act as a Qualifying Individual when applying for the metal products contractor license

  • Licensed General Contractor
  • C-61 / D-24 License Holder
  • Former Supervisor (within the last 10 years)
  • check
    Fellow Employee (within the last 10 years)
  • check
    Business Associate
  • check
    Fellow Journeyman
  • check
    Union Representative

How to fill out the Contractor License application

In addition, your Qualifying Individual will need to provide a brief but detailed description of your knowledge and skillset.

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

“Jose knows how to fabricate filing cabinets” is not descriptive enough.

 The CSLB will want to see something more like:

"Jose has worked with various types of metal products to create filing cabinets, lockers, modular storage structures, and mail chutes"

Most importantly, the description written by your qualifying individual has to include the core skills a metal contractor is expected to have.

Work experience for the Contractor 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 which include:

  • 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.

However, 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.

Application Processing, 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 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 

Contractor License Fees

The Current CSLB fees are: 

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

Having a criminal record in no way stops you from getting a C-61/D-24 Metal contractor 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.

Typically the CSLB is most concerned with Fraud, Embezzlement and Forgery.
