Trade licences by state: how to find exactly what you need
There is no single national licence for most trades. Each state decides which trades need a licence, what the requirements are and how often it must be renewed - and many cities and counties add their own.
Start with the state board
Search for your state's licensing board for your trade: contractors, electricians, plumbers, HVAC, and others often have separate boards. Their site lists:
- whether a licence is required for your work,
- the classes or levels of licence,
- experience, exam and education requirements,
- insurance and bond requirements,
- fees and renewal cycles.
Know the thresholds
Some states only require a licence above a certain job value or for certain types of work. Others license almost everything. Do not assume a small job is exempt - check.
Then check locally
Cities and counties may require a business licence, a local trade registration or permits for specific jobs. Permits are per job, not per business: a licensed contractor still pulls permits where the work requires them.
Working in more than one state
A licence in one state usually does not let you work in another. Some states have reciprocity agreements that make the second licence easier, but you still need to apply.
Keep it current
- Put every renewal date in your calendar.
- Track continuing education hours if your trade requires them.
- Update the board when your business name, address or ownership changes.
Show it
Customers increasingly check. Put your licence number on your quotes, invoices, vehicle and website where your state allows or requires it. It builds trust before you even arrive.
