Verify a California elevator contractor's C-11 Elevator Contractor license before dispatching them for modernization or maintenance work
domain: cslb.ca.gov — Contractors State License Board, C-11 classification · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Use the CSLB license lookup tool to search the contractor by name or license number
Confirm the license carries the C-11 (Elevator) classification specifically, not just a general contracting classification
Check license status (active, expired, suspended) and bond/insurance flags shown on the record
Cross-reference with dir.ca.gov guidance noting that a full maintenance contract with a C-11-licensed firm can support a longer-duration DOSH conveyance permit
Confirm classification scope on cslb.ca.gov's Licensing Classifications page (C-11) if the work in question is borderline (e.g., dumbwaiters, moving walks) rather than assuming coverage
Known gotchas
A general B contractor license is not sufficient for elevator work — the C-11 classification specifically must be present on the license
CSLB status can lag real-time for very recent renewals or disciplinary actions; treat the lookup as current-as-of-refresh, not instantaneous
C-11 scope (per CSLB's own classification description) extends to escalators and moving walks in addition to elevators, so don't assume a separate license is needed for those in California
