Licensing rules for contractors differ from state to state, and sometimes city to city. Here's how to check any contractor, wherever you live.
Usually licensed by the state
- Plumbers and electricians are licensed by the state in most places. Your state's licensing board has an online lookup.
- HVAC and general contractors are licensed by the state in some states and by cities or counties in others.
- Movers that cross state lines must register with the U.S. Department of Transportation.
Often licensed locally
Many cities and counties require their own contractor license or registration, especially for roofing and remodeling. Ask for the one that matches your address.
Five checks before you sign
- Verify the license or registration.
- Ask for proof of insurance.
- Get a written scope and price.
- Tie payments to finished work, not dates.
- Ask who pulls the permit.
