About the C-5 — Framing & Rough Carpentry License
The C-5 Framing and Rough Carpentry license covers the structural skeleton of buildings — the framework that everything else is built upon. C-5 contractors install wood and metal framing, roof trusses, sheathing, subflooring, and other structural components. This is one of the most physically demanding and technically important trades in construction, as the quality of framing directly affects a building's structural integrity and safety. In earthquake-prone California, proper framing techniques and seismic considerations are especially critical. C-5 contractors must understand load calculations, building codes, and engineering specifications. When hiring a framing contractor, look for experience with your project type, verify they follow current seismic codes, and ensure they coordinate well with other trades that will follow their work.
About the C-6 — Cabinet, Millwork & Finish Carpentry License
The C-6 Cabinet, Millwork and Finish Carpentry license covers the fine woodworking and finishing touches that define a home's character. C-6 contractors build and install custom cabinetry, trim work, crown molding, wainscoting, built-in shelving, and other decorative and functional wood elements. This trade requires precision craftsmanship and an eye for detail, as finish carpentry is highly visible and must meet exacting standards. Whether you're renovating a kitchen with custom cabinets or adding architectural details throughout your home, a skilled C-6 contractor can dramatically improve both the appearance and value of your property. When selecting a C-6 contractor, ask to see examples of their previous work, discuss material options and wood species, and get a clear understanding of timelines since custom work often takes longer than standard installations.
