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. They ensure that anyone charging over $500 for construction services is qualified and registered with the state.
- The CSLB issues the construction clean-up contractor license in the state of California.
- The CSLB has a state-wide task force that conducts sting operations targeting unlicensed construction activity.
- Getting caught contracting without a license in California is punishable with fines up to $15,000 and 6 months in the county jail
Blue Print Reading Course

Being able to read and understand blueprints is a core skill for anyone working in or around a construction site.
Identifying the structural details and dimensions of a building before beginning the clean-up process can be very valuable.
Construction blueprints communicate an array of information to builders.
Being comfortable with construction blueprints is an invaluable skill for all tradesmen, but can be especially important for a construction clean-up contractor who may be a part of a larger construction project.

C-61/D-63 Construction Clean-up License Requirements
To get the construction clean-up contractor 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 qualify for an exam date you must meet 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 #
- Not Currently on probation or parole
You must also have:
- 4 Years Journey Level Experience
- A Certifier to sign off on your experience
- A way to prove your experience if the state asks for documentation
What is a Journey level experience?

Journeyman-level experience means that you have worked unsupervised full-time for a construction clean-up company, or for a contractor that holds the C-61/D-63 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 Certifier
The following people may be used as certifier to sign off on your experience when applying for the construction clean-up contractor license:
- Licensed General Contractor
- C-61/D-63 License Holder
- Fellow Employee (within the last 10 years)
- Former Supervisor (within the last 10 years)
- Business Associate
- Fellow Journeyman
- Union Representative
Filling out the Contractor License Application
- Your certifier will also need to provide a brief but detailed description of your knowledge and skill set.
- The way this description is written will be critical to whether or not your application is accepted. For example:
“Sam is a nice guy and very experienced” is not descriptive enough for the CSLB.
The people reviewing your application will want to see something like:
“Sam has cleaned up residential and commercial job sites and has safely disposed of various construction debris. Sam knows how to operate a dump truck as well as using a variety of cleaning products in adherence to EPA standards” etc.
- The description written by your qualifying individual will need to include the core skills required for the construction clean-up contractor license.
Proving your work experience

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 somewhere 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
State Fees
The current state fees are:
1. State Application Fee (one-time fee per application sent to the state board )
2. License Activation Fee ( paid every two years )
You will also need to pay for live scan fingerprinting.
Construction Bonds

Upon passing the exam, the state board requires you to have a Contractor Bond number. A construction bond is a security deposit issued by a surety company.
- Bonds are designed to protect the consumer public against contractor default. They act as protection mechanisms for clients from unethical or illegal actions performed by contractors.
- Bonds also ensure that subcontractors get paid for their work.
- Furthermore, they ensure or that a contractor performs his duties as stated in a contract.
Construction bonds protect employees, suppliers, sub-contractors, or clients against a contractor's failure to abide by an agreement.

Can you get a Contractor's License with a Felony in California?

Having a criminal record in no way stops you from getting a sandblasting 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. In my experience, they are primarily concerned with criminal charges associated with Fraud, Embezzlement, and Forgery.
