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.

What does a C-6 license cover?
A C-6 license covers the fabrication and installation of cabinets, millwork, trim, molding, built-ins, and other finish carpentry. This includes both custom shop work and on-site installation of decorative and functional wood elements.
Should I choose custom or stock cabinets?
Custom cabinets offer perfect fit, unique designs, and higher quality materials but cost more and take longer. Stock cabinets are budget-friendly and quick but come in standard sizes. A C-6 contractor can advise on the best option for your space and budget.
Do I need a licensed D24 contractor in California?
Yes. California law requires a licensed contractor for any d24 work valued at $500 or more. Licensed contractors must pass exams, maintain bonding, and carry insurance. Hiring unlicensed contractors puts you at risk.
