Who Needs the C-4 License?
Contractors who do any sort of heating, steam-fitting, or boiler work. If you do any sort of hot water work or work involved in pressurized water involving project costs over $500, you absolutely need a C-4 license.
In reality, that means most anyone doing this work, as anything involving boilers or furnaces or chimneys or anything of that sort will involve expensive materials and labor.
When Do You Need a C-4 License?
Any of the above projects exceeding $500 in labor and materials necessitates a C-4 license. This requirement applies regardless of the project’s complexity or scale.
For smaller projects under $500, a C-4 license is not mandatory. But in reality, thatâs rarely applied to anyone working on hot water systems. Considering the cost of most hot water projects, you can expect to need a license.
When it comes to the C-4 license, very few jobs donât require a C-4 license. You can get away with small jobs like replacing a valve or doing routine testing, but anything beyond basic maintenance will quickly get expensive in California.

Should I Get Multiple Licenses As A C-4 Contractor?
Considering how important and interconnected hot water systems are to the larger construction project, C-4 contractors might find themselves wondering if it makes sense to get additional licenses in order to provide a broader service to your community â and make a little bit of extra money in the process.
The answer is â definitely! If you can handle bigger projects, you can naturally make more money as a contractor, and considering you probably already have broad construction knowledge due to the interconnected nature of hot water systems, itâs absolutely worth it to invest in additional licenses to improve your bottom line.
When it comes to getting additional licenses for C-4 hot water systems contractors, you should look for licenses that are complementary to the C-4 license, involve hot water or heating, or are areas of construction where you have existing knowledge.
Class B General Contractor License: Considering how much you need to know to effectively perform the job of an interconnected hot water system like a boiler or a heat pump, you will naturally learn the skills a gen con needs to succeed as well. Picking up this classification will open up a whole new world of contracting opportunities.
C-36 Plumbing License: Plumbing and heating systems go hand-in-hand on pretty much any project, especially in large buildings like schools or apartment buildings, where heating systems may involve extensive piping. By holding both C-4 and C-36 licenses, you can offer a full range of services related to both plumbing and heating. For example, you can install the boiler, do the pipe installation to the shower, and install the shower piping. If you can do all that for your local community, you will never run out of new clients.
C-20 Warm-Air Heating, Ventilating, and Air-Conditioning License: The C-20 license is for heating, ventilation, and air conditioning â anyone can see how these two skill sets dovetail. Since HVAC systems often need to integrate with boiler and hot water heating systems, especially in giant commercial or residential complexes, holding both C-4 and C-20 licenses is a no-brainer for hiring managers. Any customer can see the value in someone who can install all of the heating and cooling systems for their project. Not only can you save them money, but you can net a much bigger profit, without much added cost.
Conclusion
If youâre a steamfitter or a hot water systems specialist, we donât have to tell you â thereâs money to be made working on these systems!
Itâs a no-brainer to get your C-4 license if you work on anything related to hot water projects in California. Itâs a tiny investment in what is an extremely lucrative specialty in a state that will have continued needs for hot water systems contractors.
