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-2 — Insulation & Acoustical License

The C-2 Insulation and Acoustical contractor license covers the installation of insulating and acoustical materials for thermal, sound, and fire protection purposes. This includes installing insulation in walls, attics, and crawl spaces, as well as acoustical ceiling tiles and soundproofing systems. With California's strict energy efficiency requirements (Title 24), C-2 contractors play a vital role in helping homes and businesses meet building codes and reduce energy costs. Proper insulation can significantly lower heating and cooling bills while improving indoor comfort. When hiring a C-2 contractor, ask about R-value recommendations for your climate zone, the types of insulation materials they use, and whether they perform energy audits. Quality insulation work is one of the best investments homeowners can make for long-term energy savings.

About the C-9 — Drywall License

The C-9 Drywall license covers the installation, taping, texturing, and finishing of drywall (also known as sheetrock or gypsum board). Drywall is the standard interior wall and ceiling surface in modern construction, and the quality of its installation directly affects the appearance of a finished room. C-9 contractors handle everything from hanging sheets to applying final textures and finishes. Different projects require different finish levels, from basic garage walls (Level 1-2) to smooth, paint-ready surfaces (Level 4-5). Specialty applications include moisture-resistant board for bathrooms, fire-rated assemblies, and soundproof installations. When hiring a C-9 contractor, specify the finish level you expect, discuss texture options, and ask about their process for minimizing dust. Quality drywall work is essential for a professional-looking final result.
