Most trade licenses come from a state board, and they stop working at the state line. If you move from Phoenix to Portland carrying a journeyman card, you may face a stack of paperwork, a new exam, or both. Contractor license reciprocity covers the agreements and shortcuts that let a license, or the exam behind it, count in a second state. Some trades and license levels move easily. Others barely move at all.
This guide uses what licensing agencies publish themselves to show where the real shortcuts are, which licenses travel best, and what to check before you sign a lease somewhere new.
What contractor license reciprocity actually means
People use the word reciprocity loosely. In practice, you will run into one of three situations:
- A true reciprocal agreement. Two states agree that their requirements are close enough. If you hold a license in one, the other will issue its equivalent without making you sit its exam.
- Exam acceptance. The new state still licenses you on its own terms but accepts a passing score from a recognized national exam in place of its trade exam. The application, fees and any other requirements still apply.
- No shortcut. The new state has no agreement covering your license class, so you qualify the same way a local applicant would.
None of these is automatic. You always file an application with the new state's board, and you can't work under your old license while you wait. Oregon's Building Codes Division, for example, says verifying a license for reciprocity currently takes 4 to 6 weeks, that incomplete applications slow things down, and that application fees are not refunded. Build that lag into any move.
The NASCLA exam: the closest thing to a national contractor license
No national contractor license exists. The nearest thing is the exam program run by the National Association of State Contractors Licensing Agencies (NASCLA). Its accredited exam page lists two programs: one for commercial general building contractors and one for electrical.
The process has three steps. First, you get pre-approval through NASCLA to sit for the exam. After you pass, you register in NASCLA's National Examination Database to get your transcripts. Then you apply to each state agency where you want to be licensed. Passing the exam doesn't license you anywhere by itself. It gives you a score that participating boards will honor.
For the commercial building exam, NASCLA's participating agencies list names 20 agencies. That is 17 states plus the U.S. Virgin Islands, because Alabama and South Carolina each have two boards on the list. The catch is that many of them attach conditions:
| Agency | Condition on the NASCLA commercial exam |
|---|---|
| Arizona Registrar of Contractors | Counts for the B-1 and B-2 commercial classes; the exam date on your transcript must be within the past two years |
| California CSLB | B General Building exam can be waived only for out-of-state applicants who have held a license in good standing for at least five years; California residents take the state trade exam |
| Florida CILB | Replaces the trade exam, but you still take Florida's business/finance and building code portions |
| New Mexico CID | Replaces the trade exam for the GB98 license; you also need a letter of good standing showing one year of licensure elsewhere |
| Oregon CCB | Accepted in place of the 16-hour pre-licensure training |
| South Carolina Residential Builders Commission | Exam must have been passed within the past three years |
| Utah DOPL | No trade exam required; the NASCLA exam can satisfy the two-year experience requirement for general contractors |
| West Virginia | Won't take scores or transcripts dated before September 1, 2013 |
| Alabama (both boards), Arkansas, Georgia, Louisiana, Mississippi, Nevada, North Carolina, South Carolina CLB, Tennessee, Virginia, U.S. Virgin Islands | Listed as accepting the exam; Arkansas ties it to documented experience, and North Carolina applies it to commercial and residential building classes |
Two cautions. Many entries on NASCLA's list carry "as of" dates, so confirm with the board before you rely on one. And the electrical program has its own separate list. The participating-agencies page says plainly that its list does not cover the electrical exam, so look up the electrical list on its own if that is your path.
Electrician license reciprocity: real, but regional
Electricians usually get reciprocity through two-way agreements between states, not a national exam. Oregon is a useful example because its Building Codes Division spells out the partners and the conditions:
| Oregon license | Reciprocal with |
|---|---|
| General Journeyman Electrician (J) | Arkansas, Idaho, Maine, Montana, Utah, Washington, Wyoming |
| General Supervising Electrician (S) | Arkansas, Utah |
| Journeyman Plumber (JP) | Idaho, Montana |
The electrical conditions show what these agreements test for. You must have qualified for your home state's journeyman exam through four years of apprenticeship education (at least 576 classroom hours) and at least 8,000 hours of work under a licensed journeyman's direct supervision. Washington applicants also need to have completed their apprenticeship in Oregon or Washington and passed Washington's exam.
That leads to three patterns worth knowing:
- The higher the license, the fewer the partners. Oregon's journeyman license reaches seven states. Its supervising license reaches two.
- Documented hours carry the agreement. Boards are checking that your training matched theirs. A clean record of apprenticeship hours and classroom time matters as much as the card does.
- No daisy-chaining. Oregon accepts a reciprocal license only from a state where you actually tested. You can't take a license you got by reciprocity and use it to get a third one.
Plumbing license reciprocity: usually the hardest move
In the Oregon example, plumbers have the fewest options of any licensed trade on the page. The journeyman plumber license is reciprocal with just Idaho and Montana. Oregon publishes the agreement documents but no separate plumbing conditions beyond them, so read the agreement for your state pair closely.
One state is a single data point, not a national rule. Still, it fits the general shape: agreements exist only where two states judge their requirements substantially similar, and that bar is easier to clear in some trades than others. If you're a licensed plumber thinking about a move, plan as though you may have to test again unless the new state's board tells you otherwise in writing.
Which trade licenses travel best, ranked
This is our editorial ranking, built from the agency rules above. Treat it as a starting point and confirm everything with the board you're moving to.
| Rank | License | Portability | Why |
|---|---|---|---|
| 1 | Commercial general building contractor | High | One NASCLA exam is honored by 20 agencies, though each adds its own conditions |
| 2 | Journeyman electrician | Moderate | Regional agreements exist (seven partners in Oregon's case), tied to documented apprenticeship hours |
| 3 | Master or supervising electrician | Low to moderate | Fewer agreements at the higher level (two in Oregon's case) |
| 4 | Journeyman plumber | Low | The narrowest agreements in the examples we checked |
| - | Trades your new state doesn't license individually | Not applicable | Nothing to transfer, but check city and county rules and any contractor registration |

Moving your trade license to another state: a checklist
Run through this list before you commit to a move. Start at least two months ahead.
- Find the right board and class. Identify the new state's licensing agency and the exact license class that matches the work you do. Names and scopes differ from state to state.
- Look for an agreement at your level. A journeyman agreement may not cover a master or supervising license.
- Confirm you tested at home. If your current license came through reciprocity, expect it to be rejected as a basis for another one.
- Gather proof of hours. Apprenticeship completion records, classroom hours and supervised work hours are what boards check against their own rules.
- Order verification early. Your current board will need to confirm your status and scores. Oregon quotes 4 to 6 weeks for this step alone.
- Check exam date windows. If you're using NASCLA scores, note limits like Arizona's two years and South Carolina residential's three years.
- Expect add-ons. A business and law exam, a local code exam or a letter of good standing may still be required, as in Florida and New Mexico.
- Keep your home license active. California's five-year good-standing condition and New Mexico's one-year letter both reward people who never let their license lapse.
- Budget for fees you won't get back. Application fees are often non-refundable, so submit a complete packet the first time.
Before you quit your job: get the new board's answer in writing on whether your license qualifies. A web page can be out of date. An email from licensing staff about your specific license is much harder to dispute later.
If you might move someday, plan for it now
Portability is mostly decided years before a move. Take your licensing exam in the state where you trained instead of getting licensed through a shortcut, so you hold a license that counts as tested. Keep a running log of hours and classroom time, signed off as you go. Renew on time, because several conditions above depend on years in good standing.
If you're heading toward running jobs as a commercial general contractor, the NASCLA exam is worth a serious look. One score opens doors with 20 agencies, and the agencies that set conditions mostly care about recency, so take it close to when you plan to apply. If you're still choosing where to settle, compare pay and demand in our guide to the best states for tradespeople alongside the licensing rules here.
Bottom line: Commercial general contractor licenses are the most portable, thanks to the NASCLA exam. Journeyman electricians come next through regional agreements. Master-level licenses and plumbing licenses travel least. Whatever your trade, test in your home state, keep your license in good standing, document every hour, and get the new board's answer in writing before you move.
