Confirm California contractor license classification needed for terrazzo or resinous flooring work

Steps

1. Confirm California's C-15 'Flooring and Floor Covering Contractor' classification scope directly at cslb.ca.gov before assuming it covers a specific material — the CSLB's own classification page is the authoritative source, not third-party contractor-school summaries.
2. Note that C-15's published scope explicitly excludes ceramic tile (a separate tile classification) — verify with CSLB directly whether terrazzo requires a different classification, rather than assuming it's automatically included in 'flooring and floor covering.'
3. For resinous/epoxy flooring specifically, confirm which classification(s) a contractor holds actually cover polymer flooring installation, since epoxy/urethane systems may be interpreted differently than traditional resilient/wood flooring.
4. Check the dollar threshold (labor and materials) at which a license is legally required at all on a given job, per CSLB's general licensing rules.
5. Where scope is ambiguous, request written confirmation from CSLB or verify the contractor's license classification directly on the CSLB license lookup tool rather than relying on the contractor's self-description.
