How do I know if a service provider needs a license?

Regulated trades

Electricians, plumbers, HVAC technicians, and contractors handling structural work almost always require licensing. These trades involve safety risks—electrical fires, gas leaks, or building code violations. Your local building department website lists regulated professions in your area.

General contractors

License requirements vary by state and job value. Some states require licenses for any construction work; others only above a certain dollar amount. Check your state's licensing board online.

Home inspection and pest control

Most states license home inspectors and pest control operators due to health and safety implications. Real estate transactions often mandate licensed inspectors.

Cosmetology and personal services

Hair salons, nail technicians, massage therapists need licenses in most jurisdictions. These protect consumers from disease transmission and unsafe practices.

Unlicensed providers

Hiring unlicensed practitioners for regulated work can void insurance coverage and violate building codes. Work may need redoing at your expense. Additionally, you have no recourse if something goes wrong.

How to verify

Search your state or local licensing board website with the provider's name. Legitimate professionals provide license numbers without hesitation.
