The Contractors State License Board (CSLB) is the governing body for all contractors in the state of California.
Their responsibility is to protect the consumer public and ensure that anyone charging over $500 for plumbing services is qualified and registered with the state of California.
The C-47 license is issued to manufactured housing contractors.

How to get the C-47 License
To get a C-47 license in California, you must meet the following basic requirements:
You must also have:
What is a Journey level experience?
Journeyman level experience means that you have worked unsupervised full time for an construction company or someone that holds the C-47 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-47 license:
Filling out the C-47 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 built our mobile home” is not descriptive enough
The CSLB will want to see something like:
"Ed has installed and repaired manufactured housing, built foundations, prepared for transport, done drywall, flooring, carpentry and electrical hook ups" etc.
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.
- Tax Returns
- Check Stubs
- 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.
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:
- Time of year (processing time slows down during the holidays)
- Criminal History
- Proving Experience
- Mistakes on your application
Application Costs for the C-47 License
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-47 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 primarily concerned with criminal charges associated with:

C-47 License Practice tests and Exam Prep
Some things to remember:
- The questions you will see on the exam may use outdated terms
- Processes may be completely different from how things are done on the job site
- You will see questions about things you may have never done before
- Questions will be presented to you as if you are running a large scale construction business with several employees and jobs happening all at once.
- Know all aspects of your trade
If you don’t have the 4 years required journeyman level construction experience required to get a C-47 license, your journey begins here.
Generally, someone looking to get into the trades would begin by finding a union or apprenticeship program.
