What Is a C-17 License?
What does a Glazing Contractor do?
Generally a glazing contractor’s duties would include:
To get the C-17 license you have to be familiar with all aspects of the glazing trade
Contractors that hold the C-17 license can work in a variety of settings.
- They may install or shape glass windows as part of a customized project for a client.
- They may also be subcontracted by a General Contractor who has placed a bid on a project that includes glazing.
A General Contractor would oversee that the glass contractor has executed their duties safely.
Check out this article for an in-depth look at the General Contractor License.
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-17 License is issued to glazing 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 your C-17 License
To get a C-17 license in California, you have to meet the following requirements:
What is Journey Level Experience?
Journeyman level experience means that you have worked unsupervised full time for an glazing company, or for a contractor that holds the C-17 License.
- A journeyman glass contractor 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
A qualifying individual can any of the following people:
Proving Your Work Experience for the C-17 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.
Filling out the C-17 License Application
- Your Qualifying Individual will also need to provide a brief but detailed description of your glazing knowledge and skillset.
- The way this description is written will be critical to whether or not your application is accepted.
- For example:
“Bob, is a nice guy he replaced the windows in my bathroom” will not be enough for the CSLB.
The CSLB will want to see something like: "Bob has used drills, smoothers, polishers, has cut and installed insulated glass"
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-17 License

Can you get a Contractors License with a Felony in California?
Having a criminal record in no way stops you from getting a C-17 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:
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.
