Working outside the Specialty Contractor — Carpentry (limited to the specific specialty) scope can trigger unlicensed-contracting penalties.

Missing workers compensation

Hiring helpers without workers comp is a common cause of stop-work orders and fines.

Expired bond or insurance

Lapsed bond or liability insurance automatically suspends most carpentry registrations.

Ignoring local permits

A state license or registration does not replace municipal building permits and inspections.
