Sanitation systems contractors provide one of the most important services in the construction industry. Sometimes referred to as:
- Sewer Contractors
- Septic System Contractors
- Sanitation Engineers
- Waste management consultant
Functioning sanitation systems are one of the cornerstones of living in a modern society.
With 7 billion people on the planet, never at any point in history has there been more of a demand for efficient sanitation systems as now.
In this article we will go into detail about everything you need to know about C-42 license requirements, the exam, study guides, and even how to fill out the license application.
What is a Sanitation Systems Contractor?
"A sanitation system contractor fabricates and installs cesspools, septic tanks, storm drains, and other sewage disposal and drain structures. This classification includes the laying of cast-iron, steel, concrete, vitreous and non-vitreous pipe and any other hardware associated with these systems"-CSLB.GOV
The C-42 is the classification required in the state of California for all persons looking to bid on the fabrication and installation of sanitation systems where the cost of labor and materials exceeds $500.
Duties associated with the C-42 license
Sanitation systems contractors engage in a wide variety of duties including:
To get the the sanitation systems classification, you will have to be familiar with all aspects of sanitation systems.
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-42 license is issued to 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.
General Engineering Contractor License
Sanitation companies that hold the C-42 contractor license often are contracted in a public works setting.
Meaning they are being paid from public tax payer funds to complete sanitation systems projects.
They may in some cases work with a company or property owner.
However, in many cases they work as a sub to a General Contractor or General Engineering Contractor to continually engaging sanitation systems to work for multiple projects over an extended period of time.
General Contractors oversee that the Sanitation systems subcontractor has executed their duties in adherence to code as well as in adherence to environmental safety standards.

How to get the C-42 license in California
To get a sanitation contractor 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 a sanitation company, or contractor that holds the C-42 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.
Filling out the Sanitation Contractor 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.
“Tom is a great guy, he replaced our storm drain” is not descriptive enough.
The CSLB will want to see something like:
"Ed has installed septic tanks, pre-cast manholes, catch basins, clarifiers for industrial waste and drain fields".
The description written by your qualifying individual will need to include the core skills required a sanitation contractor.
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-42 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-42 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:
Fraud, Embezzlement and Forgery.
