How Contractor License Transfer Works: Trades, Reciprocity, NASCLA, and NERA
Last verified: 2026-08-07
A contractor license transfers by trade and class through one of four routes: a trade-specific reciprocity agreement (waives that trade's exam), the NASCLA exam network (commercial general building, ~15 states), the NERA network (electrical, ~14 states), or licensure by endorsement/new application where none applies. Business, law, bonding, and insurance requirements almost always remain.

Why there is no contractor compact
Construction licensing is fragmented by design: states license different trades, at different classes, through different agencies, and some devolve general-contractor licensing to municipalities entirely. That structure resists a single compact, so portability grew as bilateral trade agreements and two voluntary exam networks. The practical rule: your trade and your class determine your options, and the destination state's board is the only authority that matters.
What reciprocity actually gets you
Read every agreement as an exam waiver, not a license transfer. A reciprocity deal typically waives the destination's trade or technical exam for your specific trade and class. You still file the application, pass the business and law exam, submit a financial statement, post the required bond, and carry insurance. Contractors who assume reciprocity means "walk in and work" lose weeks discovering otherwise.
NASCLA and NERA: the portability shortcuts
If you do commercial general-building work across state lines, the NASCLA Accredited Examination is the single most useful credential you can hold — about 15 states accept it toward licensure. If you are an electrician, NERA membership lets roughly 14 states waive your exam. Both reward planning: earn the credential before the move, and confirm the current member list on the board, since networks add and drop states.
Common pitfalls
Three cost contractors real money. Assuming a residential agreement covers commercial work (it usually doesn't — classes are separate). Assuming your general-contractor license implies trade licenses (electrical, plumbing, and HVAC are typically licensed and reciprocated separately). And trusting an aggregator's reciprocity count — the boards contradict the popular Nevada and Utah figures directly. When the stakes are a bid deadline, verify with the board.

Frequently asked questions
Does a general contractor license let me do electrical or plumbing work in a new state?
Generally no. Electrical, plumbing, and HVAC are licensed — and reciprocated — separately from general building in most states. Each trade has its own agreements, exams, and (for electrical) the NERA network.
Is the NASCLA exam worth it?
For commercial general contractors working across state lines, usually yes — about 15 states accept it toward their commercial GC license, replacing each state's own trade exam. It is a one-time exam that travels.
Do I still need a bond and business exam if reciprocity applies?
Almost always. Reciprocity waives the trade exam; the business/law exam, financial statement, bond, and insurance are separate requirements the destination state keeps.
Why does this site's reciprocity count differ from others?
Because we count by trade and class and cite the state board, while aggregators combine unrelated per-trade waivers into one inflated number. Where sources conflict, the board wins.
