About the B — General Building License
A General Building (Class B) license is one of the most common contractor licenses in California. It authorizes the holder to construct, alter, or repair buildings and structures. This includes residential homes, commercial buildings, and industrial facilities. A Class B contractor can use two or more unrelated building trades on a single project, making them ideal for comprehensive construction and renovation work. They often serve as the primary contractor who coordinates subcontractors for specialized trades. When hiring a General Building contractor, homeowners should verify the license is active and in CLEAR status, confirm adequate insurance coverage, and always get a detailed written contract before work begins. General Building contractors must maintain a $25,000 contractor bond and carry workers' compensation insurance if they have employees.
About the C-4 — Boiler, Hot Water Heating & Steam Fitting License
The C-4 Boiler, Hot Water Heating and Steam Fitting license authorizes contractors to install, maintain, and repair boilers, hot water heating systems, and steam fitting equipment. This specialized trade requires deep knowledge of pressure systems, safety protocols, and building codes. C-4 contractors work on both residential and commercial projects, from home radiant heating systems to large commercial boiler installations. Given the potential safety hazards of pressurized heating systems, it is critical to hire only licensed professionals for this type of work. California requires regular inspections of commercial boiler systems, making qualified C-4 contractors essential for building owners. When hiring, verify the contractor has experience with your specific type of system and ask about their emergency service availability.
About the C-7 — Low Voltage Systems License
The C-7 Low Voltage Systems license covers the installation, maintenance, and repair of systems that operate on low electrical voltage. This includes security alarms, fire detection systems, data and communication cabling, home automation, intercoms, CCTV surveillance, and structured wiring. As smart home technology and security needs continue to grow, C-7 contractors are increasingly in demand. Unlike C-10 electricians who work with standard electrical power, C-7 specialists focus on signal and data systems. This distinction is important because improper installation of low voltage systems can affect performance, void warranties, or create safety issues. When hiring a C-7 contractor, ask about their experience with your specific system type, whether they offer monitoring services, and if they stay current with rapidly evolving technology standards.
