Steps
Review the CSLB C-35 classification description to confirm the scope covers the specific plaster, stucco, or lath work being bid
Verify the applicant/contractor meets the four-year journeyperson/supervisory experience requirement in the trade within the required look-back period
Check whether the project also requires a separate classification (e.g., waterproofing or painting) for adjacent scopes not covered by C-35
Confirm license status, bond, and workers' comp are active on the CSLB public license lookup before contracting
Retain the CSLB study guide/classification detail page reference for scope disputes with owners or GCs
Known gotchas
C-35 scope covers application of the coating and the lath/furring system itself, but adjacent trades (e.g., water-resistive barrier installation on new construction) can fall under other classifications depending on the work split — confirm rather than assume
Classification descriptions are occasionally updated; rely on the current CSLB classification detail page, not a cached study guide, for scope disputes
