How to get Your C45 Sign Contractor License in CA

What kind of work can a Sign Contractor perform?

A C45 sign contractor is licensed to perform a wide range of tasks related to both electrical and non-electrical signs. This includes fabricating, installing, and erecting electrical signs, along with handling the necessary wiring for these signs. They can also install post or pole-supported signs, often seen outdoors in parking lots or along roads, as well as signs that are attached to buildings or other structures. In addition, C45 contractors are responsible for creating and applying painted wall signs, as well as modifying or repairing existing signs. Essentially, they are equipped to manage the design, installation, and maintenance of various types of signage, whether they require electrical components or not.

Who needs the C45 license?

Anyone who plans to work as a sign contractor in California and take on projects that involve the fabrication, installation, or modification of signs needs a C45 Sign Contractor License. This is particularly crucial because California law requires that any contractor performing work on a project valued at $500 or more, including both labor and materials, must have a valid contractor license. Without this license, sign contractors cannot legally bid on or complete projects that meet this threshold. Whether it's installing large post-supported signs, wiring illuminated signs, or modifying existing signage, anyone in this line of work must have a C45 license to operate legally and avoid penalties.

What if I only install non-electrical signs?

If your work focuses solely on non-electrical signs—such as painted wall signs, vinyl graphics, or signs that don’t require wiring—you may not need a full C45 Sign Contractor License. Instead, the Contractors State License Board (CSLB) offers the C61-D42 Limited Specialty License for Non-Electrical Signs. This license allows you to fabricate, install, and modify non-electrical signs without engaging in electrical work.

In addition to meeting legal requirements, having the C42 license signals to clients that you’re qualified to manage sanitation projects safely and effectively, opening up more opportunities for higher-paying jobs and larger projects.

An important difference with the C61-D42 license is that applicants are only required to pass the Law & Business exam—there is no trade exam portion like there is for the C45 license. This makes the process quicker for those specializing exclusively in non-electrical signage.

California License Requirements for the C45 Classification

To obtain the C45 Sign Contractor License in California, you must meet the requirements set by the Contractors State License Board (CSLB). These include:

1. Be at least 18 years or older.
   You must be legally considered an adult to apply for any contractor’s license in California.
2. 4 years of journey level experience.
   When considering this requirement, you must demonstrate four years of journey-level experience within the past 10 years. This experience is typically acquired by working for a licensed contractor, but it can also be a combination of completed apprenticeship programs, education, and fieldwork.
3. Provide a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN).
   The CSLB requires either an SSN or ITIN for identification and tax purposes.

Application Process for the C45 License

Before you can take the required exams for the C45 license, your application must first be approved by the state. This means you’ll need to complete the application thoroughly, submit it with the state fee of $450, and wait for approval before you can schedule your exams.

Here are a few key things to know before filling out your application:

• Establish a business entity. The Contractors State License Board (CSLB) issues license numbers to business entities, not individuals. Ensure you have established a business entity before applying.
• Get a certifier to verify your experience. To prove your four years of journey-level experience, you’ll need a certifier—someone with direct knowledge of your work—to sign the Certification of Work Experience page. This step is crucial for demonstrating your qualifications.

• Provide proof of education or apprenticeship, if applicable. The CSLB may grant up to three years of credit toward the experience requirement if you've completed accredited training or apprenticeship programs in electrical sign construction. For formal education, request official, sealed transcripts from your institution to include with your application. If your degree is from outside the U.S. and in a language other than English, it must be translated and evaluated by an accredited service.

The application is often considered the most critical and detailed part of the licensing process. Since your entire eligibility hinges on this step, it’s highly recommended to seek assistance from Contractors Intelligence School. Their experienced staff and step-by-step approach can help make the application process smooth and stress-free.

Preparing for the C45 Licensing Exam

To obtain your C45 Sign Contractor License, you’ll need to pass two exams: the C45 trade exam and the Law & Business exam. Both are required by the Contractors State License Board (CSLB) before a license number can be issued.

While it’s possible to prepare for these exams on your own, many applicants find it helpful to follow structured learning programs like those offered by Contractors Intelligence School. These programs provide a comprehensive, step-by-step approach to ensure you’re fully prepared.
