California has contractor license reciprocity agreements with five states: Arizona, Louisiana, Mississippi, Nevada, and North Carolina.1Contractors State License Board. Reciprocity Requirements If you hold a license in one of those states and want to work in California, or you hold a California license and want to work in one of them, you may be able to skip the trade exam. Everyone else applying across state lines starts the licensing process from scratch.
What a Reciprocity Waiver Actually Covers
Reciprocity waives one thing: the trade exam in the destination state. The trade exam tests hands-on knowledge of a specific craft like plumbing or electrical work. The law and business exam, which covers contracts, insurance, safety rules, and regulations specific to the state where you want to work, is never waived.
The waiver also only applies if your exact classification has an equivalent on the destination state’s reciprocal list. A California C-10 Electrical license maps to a reciprocal classification in Nevada, for example, but a niche specialty license may have no counterpart in Arizona. Before you apply, confirm your classification appears on the CSLB’s Reciprocal Classifications List.2Contractors State License Board. Reciprocal Classifications List
Coming Into California From a Reciprocal State
If you hold a contractor license in Arizona, Louisiana, Mississippi, Nevada, or North Carolina and want to get licensed in California, the CSLB requires all of the following:1Contractors State License Board. Reciprocity Requirements
- Your license is in a classification that appears on California’s Reciprocal Classifications List for your state.
- You have held an active license in good standing in that state for the previous five years.
- You submit the CSLB’s Request for Verification of License form, completed by the licensing agency in your home state.3Contractors State License Board. Forms and Applications
- You complete and submit the CSLB’s Application for Original Contractor’s License with all supporting documents.
Meet all four and California waives the trade exam for your classification. You still take California’s law and business exam.
Going From California to Another State
In the other direction, you contact the destination state’s licensing board directly, request its reciprocity application form, and have it forwarded to the CSLB for verification.1Contractors State License Board. Reciprocity Requirements Each state sets its own rules.
Nevada, for example, requires four years of active licensure with the same qualifying individual rather than five, and no history of license revocation, suspension, or disciplinary action in any state. Your qualifying individual has to pass Nevada’s Business and Law exam, and if your California classification doesn’t include an equivalent trade exam, you’ll need Nevada’s trade exam too.4Nevada State Contractors Board. Licensure by Endorsement Arizona, Louisiana, Mississippi, and North Carolina each have their own forms, fees, bonding requirements, and processing timelines.
How Much Each Agreement Actually Covers
The scope varies sharply by state.2Contractors State License Board. Reciprocal Classifications List
Arizona
Arizona has the broadest agreement, covering dozens of classifications across general engineering, general building, and specialty trades. Mapped classifications include general engineering (A), general building (B), electrical (Arizona C-11 to California C-10), plumbing (C-37 to C-36), concrete (C-9 to C-8), roofing (C-42 to C-39), landscaping (C-21/A-21 to C-27), masonry (C-31 to C-29), fire protection (C-16 to C-16), and elevators (C-18 to C-11), among others. Several Arizona K-series commercial specialty codes also map to California equivalents.
Nevada
Nevada covers a wide range of classifications under its “licensure by endorsement” process: general engineering (A), general building (B), residential and small commercial (Nevada B-2 to California B), plumbing and heating, electrical (C-2 to C-10), carpentry, painting, concrete, signs, elevators, landscaping, masonry, tile, refrigeration and air conditioning, and more.4Nevada State Contractors Board. Licensure by Endorsement A handful of Nevada classifications require you to hold two California licenses at once. A Nevada C-1 Plumbing and Heating license, for example, requires both a California C-36 Plumbing license and a C-4 Boiler, Hot Water Heating and Steam Fitting license.
Louisiana
Louisiana’s agreement is narrow. Only two classifications map across: Commercial Building and Residential Building, both to California’s B General Building. For the B General Building waiver, you also need to have passed the NASCLA Commercial Building exam and held a Louisiana General Builder license in good standing for at least five years.
North Carolina
North Carolina’s Building Contractor classification maps to either California’s B General Building or B-2 Residential Remodeling. The B General Building waiver carries the same extra condition as Louisiana’s: a passed NASCLA Commercial Building exam and five or more years holding a North Carolina General Builder license in good standing.
Mississippi
Mississippi appears on the CSLB’s reciprocal state list but covers a limited set of classifications.1Contractors State License Board. Reciprocity Requirements Check the CSLB’s Reciprocal Classifications page for the current list before applying.
Bonds and Insurance Still Apply
Waiving the trade exam does not waive the destination state’s bonding, insurance, and financial requirements. Those are separate and apply to every licensed contractor regardless of how they qualified.
Arizona bond amounts, for instance, depend on classification and anticipated annual gross volume. A residential general contractor with less than $750,000 in annual volume needs a $9,000 bond; a commercial general contractor doing over $10 million needs a $100,000 bond.5Arizona Registrar of Contractors. Bond Information Arizona also requires residential contractors to pay into the Residential Recovery Fund or post a $200,000 surety or cash bond on top of the license bond. Other reciprocal states set their own schedules.
Workers’ compensation requirements follow the state where the work is performed, not where you’re licensed. Most states require a compliant workers’ compensation policy before any work begins. Confirm the rules with the destination state’s workers’ compensation board.
If Your Target State Isn’t on the List
Most states have no reciprocity agreement with California. To work in Oregon, Washington, Texas, Florida, or any state outside the five above, you generally apply for a new license from scratch: meet that state’s experience requirements, pass both its trade and law exams, post any required bonds, and provide proof of insurance.
Some states don’t require a general contractor license at all; others license only certain specialty trades. A few accept the NASCLA exam as part of their licensing path, but that’s separate from California’s reciprocity program. Contact the destination state’s contractor licensing board directly before bidding on out-of-state work. Starting a project without a proper license can bring fines, loss of the ability to enforce the contract, and loss of lien rights.
Register Your Business Entity Separately
A reciprocal license is only one piece of working across state lines. If your contracting business is an LLC, corporation, or partnership in California and you plan to operate elsewhere, you may need to register as a foreign business entity with the destination state’s Secretary of State before doing business there. That typically means filing registration paperwork, providing a certificate of good standing from California, and designating a registered agent in the new state. Skipping this step can bring penalties and can block you from using that state’s courts to enforce contracts or collect debts.
