Verified Contractor License Requirements by State and Trade

Contractor license requirements by state and trade

Why this reference exists

Getting a contractor license in the United States is harder than it should be. Every state has its own board, its own application form, its own exam, its own bond amount, and its own renewal cycle. The information lives scattered across dozens of state government websites, written in legal language, buried under PDF links and login walls. When contractors search the web for a clear answer to a simple question — how much does a Florida roofing license cost, what experience does a Texas electrician need, how do I transfer my California general contractor license to Nevada — they usually land on a marketing page from a bond company, an exam-prep school, or an insurance broker. Those pages are written to sell something, not to inform, and most of them have not been updated in years.

ContractorLicenseRequirements.com was built to fix that. We are a free, independent reference that tells you exactly what the state board actually requires, in plain English, with the real numbers and the real rules — application fee, examination fee, bond amount, insurance minimum, experience years, exam provider, passing score, renewal cycle, continuing education hours, and reciprocity partners. Every page links to the official source set behind the summary, including the issuing board, the governing statute or rule, and any official exam-provider material that controls the application process.

What we cover

We cover the four core construction trades — general contractor, electrician, plumber, HVAC technician — plus specialty trades including roofing, painting, solar installer, landscaping contractor, masonry, carpentry, low-voltage technician, and fire sprinkler contractor. That is 688 published license guides across 51 jurisdictions, each one structured the same way so you can compare requirements without hunting for the information. Our national trade hubs show the exact number of jurisdictions currently published for each trade, and the cost calculator estimates your total out-of-pocket from application through first renewal in seconds.

What a contractor license actually is

A contractor license is, at its core, a state's promise to consumers that the person doing the work has demonstrated competence in the trade, carries enough insurance to cover damage, and has agreed to abide by the building codes and consumer-protection statutes adopted by that state. Earning the license usually means documenting between two and eight years of supervised field experience, passing a written trade examination, passing a separate business and law examination, posting a surety bond ranging from $5,000 to $50,000 depending on the state and the trade, and carrying general liability and workers' compensation insurance from the day the license issues. Renewal cycles run between one and three years and almost always require continuing education hours focused on the latest National Electrical Code, International Plumbing Code, International Mechanical Code, or trade-specific safety standards. Every state and every trade we cover is documented in this same level of detail, so a contractor researching a single jurisdiction or comparing requirements across the country can find every number they need on one site.
