California has contractor license reciprocity 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, the Contractors State License Board can waive California’s trade exam for eligible classifications. If you hold a California license and want to work in one of those states, the same courtesy may apply in reverse. What reciprocity never waives is the destination state’s law and business exam, and it only covers license classifications that both states treat as equivalent.
What Reciprocity Waives and What It Doesn’t
Under California Business and Professions Code Section 7065.4, the CSLB registrar can accept the qualifications of a contractor licensed in another state if that state offers the same courtesy to California licensees. The registrar may waive the trade exam for an applicant who provides written certification that the out-of-state license has been in good standing for the previous five years.2California Legislative Information. California Code Business and Professions Code 7065.4
The trade exam tests hands-on knowledge of a specific craft such as plumbing or electrical work. The law and business exam covers contracts, insurance, safety rules, and regulations specific to the state where you want to work. That one is never waived, in either direction.
Reciprocity also runs classification by classification. Your California C-10 Electrical license might map to a reciprocal classification in Nevada, but a more niche California specialty license may have no equivalent in Arizona. Before starting an application, check whether your exact classification appears on the CSLB’s Reciprocal Classifications List.3Contractors State License Board. Reciprocal Classifications List
What Each of the Five Agreements Covers
Arizona
Arizona has the broadest agreement with California, covering dozens of classifications across general engineering, general building, and specialty trades. Examples include general engineering (A), general building (B), electrical, plumbing, concrete, roofing, landscaping, masonry, fire protection, and elevators. Arizona also maps several of its K-series commercial specialty codes to California equivalents.
Nevada
Nevada calls its process “licensure by endorsement” and covers a substantial range of classifications, including general engineering, general building, plumbing and heating, electrical, carpentry, painting, concrete, signs, elevators, landscaping, masonry, tile, and refrigeration and air conditioning.4Nevada State Contractors Board. Licensure by Endorsement Some Nevada classifications require the California contractor to hold two California licenses at once. A Nevada C-1 Plumbing and Heating license, for example, requires both the California C-36 Plumbing license and the C-4 Boiler, Hot Water Heating and Steam Fitting license.
Louisiana
Louisiana’s agreement is narrow. Only two Louisiana classifications have California equivalents: Commercial Building and Residential Building, both mapping to California’s B General Building classification. Candidates seeking the B General Building trade exam waiver must also have passed the NASCLA Commercial Building exam and held a Louisiana General Builder license in good standing for at least five years.3Contractors State License Board. Reciprocal Classifications List
North Carolina
North Carolina’s agreement covers its Building Contractor classification, which maps to either California’s B General Building or B-2 Residential Remodeling. As with Louisiana, applicants seeking the B General Building waiver must have passed the NASCLA Commercial Building exam and held a North Carolina General Builder license in good standing for five or more years.3Contractors State License Board. Reciprocal Classifications List
Mississippi
Mississippi is listed as a reciprocal state by the CSLB, with a limited set of covered classifications. The full list is on the CSLB’s Reciprocal Classifications page, and, as with every reciprocal state, only classifications that appear there qualify for a trade exam waiver.1Contractors State License Board. Reciprocity Requirements
Coming Into California From a Reciprocal State
If you hold a contractor license in Arizona, Louisiana, Mississippi, Nevada, or North Carolina and want to be licensed in California, the CSLB requires all of the following:1Contractors State License Board. Reciprocity Requirements
- Your license must be in a classification that appears on California’s Reciprocal Classifications List for your state.
- You must have held an active license in good standing in your reciprocal state for the previous five years.
- You must submit the CSLB’s Request for Verification of License form, completed by the licensing agency in your home state.5Contractors State License Board. Forms and Applications
- You must complete and submit the CSLB’s Application for Original Contractor’s License with all supporting documents.
Meeting these requirements waives the California trade exam for your classification. You will still need to pass California’s law and business exam, which covers state-specific rules on contracts, liens, insurance, and workplace safety.
Going From California to a Reciprocal State
Going 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 requirements, and they are not identical to California’s.
Nevada, for example, requires four years of active licensure with the same qualifying individual rather than California’s five. Nevada also requires no history of license revocation, suspension, or disciplinary action in any state. Your qualifying individual must pass Nevada’s Business and Law exam, and if your California classification doesn’t include an equivalent trade exam, you’ll need to pass Nevada’s trade exam as well.4Nevada State Contractors Board. Licensure by Endorsement
Arizona, Louisiana, Mississippi, and North Carolina each have their own application forms, fees, bonding requirements, and processing timelines. The CSLB’s Reciprocal Classifications List page links to each state’s licensing board.
Bonding, Insurance, and Business Registration Are Separate
A trade exam waiver does not exempt you from the destination state’s bonding, insurance, and financial requirements. Those apply to every licensed contractor regardless of how they qualified. Arizona, for example, sets contractor bond amounts based on classification and anticipated annual gross volume, and requires residential contractors to either pay into the Residential Recovery Fund or post a separate surety or cash bond on top of the license bond.6Arizona Registrar of Contractors. Bond Information Each state has its own schedule.
Workers’ compensation coverage is governed by the state where the work is performed, not where you are licensed. Most states require a workers’ compensation policy that meets their standards before any work begins. Check with the destination state’s workers’ compensation board before starting a project.
If your contracting business is organized as an LLC, corporation, or partnership in California and you plan to operate in another state, you may also need to register as a foreign business entity with that state’s Secretary of State. That typically involves filing registration paperwork, providing a certificate of good standing, and designating a registered agent in the new state. Failing to register can trigger penalties and may prevent you from using the state’s courts to enforce contracts or collect on debts.
If Your Target State Is Not on the List
The majority of states have no reciprocity agreement with California. To work in Oregon, Washington, Texas, Florida, or any other state not listed above, you will generally need to apply for a new license from scratch: meet the state’s experience requirements, pass both its trade and law exams, post any required bonds, and provide proof of insurance.
Some states do not require a general contractor license at all, while others license only certain specialty trades. A few accept the NASCLA exam as a path to licensure, but that is separate from California’s reciprocity program. Before bidding on out-of-state work, contact the destination state’s contractor licensing board directly. Starting a project without the proper license can bring fines, unenforceable contracts, and loss of lien rights.
