Contractor License Reciprocity Finder
A reciprocity agreement lets a contractor licensed in one state obtain a license in another without retaking the trade examination. The two mechanisms are the NASCLA Accredited Examination (a standardized commercial general building exam recognized by participating states) and bilateral agreements negotiated directly between two state boards. Pick your state and trade below to see exactly what applies.
NASCLA Accredited Examination acceptance
NASCLA acceptance is most common for the commercial general building classification and is rarer for the specialty trades. It never waives a state's own business-and-law exam, financial statements, or background check.

General Contractor (10)

Bilateral reciprocity agreements
Negotiated directly between two state boards, these typically waive the trade exam for an applicant who already holds an active license in good standing in the partner state. The receiving state's business-and-law exam, insurance, fees, and background check still apply.

How to use reciprocity
- Confirm your current license is active and in good standing. Most programs require a certification letter from the issuing board dated within 30–90 days.
- Find the receiving state's reciprocity application form (separate from the standard application) on the state contractor board website.
- Verify the trade scope matches. Reciprocity rarely transfers across classifications (a Class A in one state may map to Residential-only in another).
- Take the receiving state's business-and-law examination. Reciprocity waives the trade portion in most cases but the law portion is almost always required.
- Submit financial statements, insurance certificates, and bond riders required by the receiving state. These are not waived by reciprocity.
- Disclose criminal history and prior license discipline. Reciprocity does not bypass background checks.
Reciprocity agreements change frequently. This finder is generated from the reviewed state and trade pages on this site and should always be checked against the receiving board before filing. Last full source pass: 2026-Q2.
