3. Confirm the status is ACTIVE
Only an active (or current) status means they're licensed today. Expired, suspended, or revoked is a hard stop — and a contractor who let it lapse is telling you something.
4. Check the classification matches your job
Licenses are scoped to specific trades. Confirm the classification covers the work you're hiring for, and that the name on the license matches the name on your contract.
5. Check bond, insurance, and complaints where shown
Many boards also show bond amount, workers' compensation, and complaint or disciplinary history. A bond and active workers' comp protect you; an open complaint is worth a direct conversation before you sign.
