C-61/D-12 Synthetic Products Contractor License in California
The C-61/D-12 Synthetic Products license covers a wide range of synthetic materials, including artificial turf, bathtub refinishing, epoxy coatings, synthetic countertops, pool and reservoir liners and PVC irrigation piping.
Quick answer
The C-61/D-12 Synthetic Products Contractor license lets you contract for synthetic products work in California on jobs that require a building permit, use employees, or total $1,000 or more in labor and materials. To qualify you need four years of journey-level experience in the last ten years, an approved CSLB application, and a passing score on the Law & Business exam. The D-12 is a category of the C-61 Limited Specialty classification, so there is no trade exam.

What a D-12 Contractor Can Do
CSLB definition: A synthetic products contractor installs: (a) synthetic counter tops and wall coverings; fiberglass, plastic, vinyl and epoxy products; plastic tile board and decorative art work; and synthetic turf. (b) Bathtub and enamel refinishing, resin and epoxy application, and synthetic caulking and sealants. (c) Reservoir liners, vinyl swimming pool relining, pier piling wrap, and rodent guards. (d) PVC piping systems for irrigation and drainage; subsurface irrigation drip systems. (CSLB definition for this C-61 subcategory, approved by the Board as policy; condensed. See the full text on CSLB.ca.gov.)
Typical D-12 work
- Synthetic turf (artificial grass) installation
- Bathtub and enamel refinishing
- Resin and epoxy coatings and synthetic sealants
- Synthetic countertops and wall coverings
- Vinyl swimming pool relining and reservoir liners
- PVC irrigation and drainage piping and drip systems
Needs a different license
- Ceramic tile countertops and walls (C-54)
- Landscape work beyond synthetic turf and irrigation piping (C-27)
- Water supply and drain piping inside buildings (C-36)
- Painting (C-33)
Because the D-12 covers very different kinds of work, describe the specific synthetic products you installed when you document your experience, for example turf, epoxy floors or tub refinishing.
D-12 License Requirements
CSLB uses the same core requirements for every classification. For the D-12, the qualifying individual (you, or the RMO/RME for a company) must:
- Be at least 18 years old.
- Have at least four full years of experience in synthetic products work within the last ten years, as a journeyman, foreman, supervising employee, contractor or owner-builder.
- Have that experience certified by someone with firsthand knowledge of your work, such as an employer, foreman, fellow journeyman, building inspector or homeowner.
- Pass the Law & Business exam, and complete CSLB’s asbestos open-book exam.
- Complete Live Scan fingerprinting and CSLB’s background review.
You may receive up to three years of credit toward the four-year requirement for technical training, apprenticeship or related education, but at least one year must be practical experience. There is no education requirement to get a California contractor license.
