The U.S. Contractor Licensing Board Directory — Verify Before You Hire
Every state’s contractor licensing board, how to look up a contractor’s license, how to check a bond and insurance, how to read complaint and disciplinary history, and how to file a complaint — explained state by state in plain English. We cover the licensing agency for all 50 states, its official license-lookup URL, its phone number, its complaint process, and the consumer protections (recovery funds, bonding, the right to cancel). Every board name, phone number, address, and license-lookup link is verified by a human editor against the board’s own official .gov page and kept updated.
Life-threatening emergency (gas leak, structural collapse, electrical fire, serious injury on a job site): call 911 now.

contractorsboard.org/ is an editorial directory. We are not a state contractor licensing board. We do not issue, renew, suspend, or revoke licenses. We do not verify or endorse any individual contractor. We do not handle complaints, hold bonds, or pay recovery-fund claims. The only authoritative license status is the one on your state board’s own official lookup tool. Always verify a contractor’s license directly with your state board before you hire or pay a deposit.
What This Site Covers
Contractor licensing in the U.S. is run state by state — there is no single national contractor license. Each state (and sometimes county or city) has its own board, its own rules, and its own license classifications. We cover the full picture:
State licensing boards
The official agency in each state — for example the California Contractors State License Board (CSLB), the Nevada State Contractors Board (NSCB), the Arizona Registrar of Contractors (ROC), the Oregon Construction Contractors Board (CCB).
License lookup
The official tool to check whether a contractor’s license is active, expired, suspended, or revoked — with the direct .gov URL for each state.
License classifications
General contractor vs. specialty/subcontractor classifications, residential vs. commercial, and which trades require a license in each state.
Bonding & insurance
How to verify a contractor’s surety/license bond, general liability insurance, and workers’ compensation coverage.
Complaints & discipline
How to read a contractor’s complaint and disciplinary history, and how to file a complaint with the state board.
Recovery & guaranty funds
Whether your state has a contractor recovery or guaranty fund that can compensate consumers harmed by a licensed contractor, and how to claim.
Step-by-step guides
Plain-English guides: how to verify a license, what to check before you sign, your right to cancel, and what to do if a job goes wrong.
Verified board contacts
For each board: official website, license-lookup URL, phone number, mailing address, and complaint portal — human-verified and updated.
How U.S. Contractor Licensing Is Organized
We are not a licensing board and do not license anyone; we describe the framework so readers know which body does what:
| Layer | Body | What it covers |
|---|---|---|
| State licensing | State contractor licensing boards | Issue, renew, suspend, and revoke contractor licenses; set classifications; handle complaints and discipline. Examples: California CSLB, Nevada State Contractors Board, Arizona Registrar of Contractors, Florida Construction Industry Licensing Board (DBPR), Oregon CCB, Washington L&I |
| National coordination | NASCLA | The National Association of State Contractors Licensing Agencies coordinates among state boards and offers the NASCLA Accredited Examination accepted by multiple states |
| Workplace safety | OSHA | The Occupational Safety and Health Administration sets and enforces job-site safety standards |
| Consumer protection | Federal Trade Commission (FTC); state Attorneys General | The FTC’s Cooling-Off Rule (a 3-day right to cancel certain home-solicitation sales); state UDAP statutes; deceptive-practice enforcement |
| Bonding & insurance | Surety companies; insurers | License/surety bonds, general liability insurance, and workers’ compensation that licensed contractors are typically required to carry |
| Local | City & county building departments | Building permits and inspections — separate from state licensing |
What Sets contractorsboard.org/ Apart — The Human-Verification Standard
License status changes constantly — licenses expire, get suspended or revoked, and are reinstated; boards change phone numbers and move their lookup tools; classifications are revised. Most online lists are auto-scraped and drift out of date quickly. At contractorsboard.org/, every board detail enters the site through manual editorial review — the foundation of our experience, expertise, authoritativeness, and trustworthiness (E-E-A-T):
Every board’s official .gov URL is clicked by a human editor before publication — the board homepage, the license-lookup tool, and the complaint portal. Every board phone number is dial-tested on a quarterly cycle (we confirm the line answers and routes correctly, without generating any false emergency call). Every license-lookup link is tested to confirm it reaches the live state tool. Every complaint process is checked against the board’s current published procedure. Every page carries a “last reviewed” date, and we update when a board changes its tools, phone, or process.
How to Verify a Contractor — The Eight-Step Process
- Find your state board. Use our directory to reach your state’s official contractor licensing board and its license-lookup tool.
- Look up the license. Enter the contractor’s name or license number on the board’s official tool. Confirm the license is active — not expired, suspended, or revoked.
- Check the classification. Confirm the license covers the type of work you need (general vs. specialty; residential vs. commercial).
- Verify the bond. Confirm the contractor carries the required surety/license bond.
- Verify insurance. Confirm general liability and, where workers are employed, workers’ compensation coverage.
- Read complaint & disciplinary history. Review any complaints or disciplinary actions on the board record.
- Get it in writing. Use a written contract; understand your right to cancel; never pay large cash deposits up front.
- Know your recourse. Note your state’s complaint process and whether a recovery/guaranty fund exists before work begins.
What You Will Find on Each State Page
- State board name (and the agency it sits within)

What This Site Is For
contractorsboard.org/ is the plain-English, structurally complete reference for finding your state contractor licensing board and verifying a contractor before you hire. We are completely independent. We are not affiliated with any state contractor licensing board, the National Association of State Contractors Licensing Agencies (NASCLA), the Occupational Safety and Health Administration (OSHA), the Federal Trade Commission (FTC), or any contractor, surety, or insurer. We do not license contractors, verify individuals, hold bonds, handle complaints, or give legal advice.
What This Site Is Not For
- Not a licensing board. We cannot issue, renew, suspend, or check a license — only your state board can.
- Not a contractor vetting or endorsement service. We do not recommend individual contractors.
- Not for filing complaints. File with your state board; we explain how.
- Not for emergencies. Call 911 for gas leaks, fires, structural collapse, or injury.
- Not legal, financial, or insurance advice. Consult a licensed professional.
- Not the board, OSHA, or the FTC. We describe; we do not act.
Corrections & Feedback
Boards change their tools, phone numbers, and processes. If you spot anything that does not match your state board’s current official page, tell us.
Email info@contractorsboard.org with the page URL and the detail that needs updating. We re-verify against the board’s official .gov page and update — usually within 48 hours for broken license-lookup links, dead phone numbers, and changed complaint portals.
