Contractor License Requirements
Meeting contractor license requirements is the first legal step to running a contracting business in the United States. While the exact rules vary by state and trade, most licenses require a combination of experience, passing an exam, proof of insurance, a surety bond, and application fees. This guide walks through the common requirements so you know what to prepare.

Common Requirements Across States
- Experience: Many states require 2–4 years of verifiable trade experience.
- Exams: Most licenses require passing a trade exam and a business/law exam.
- Surety bond: A contractor license bond is required before your license is issued.
- Insurance: Proof of general liability and, with employees, workers compensation.
- Application & fees: A completed application, fingerprinting, and background check.
Some states also require pre-license education, a minimum net worth, or continuing education for renewals.
Requirements by Contractor Type
General contractors are usually licensed to manage whole projects and hire subcontractors, and their licenses often have the broadest requirements. Specialty trades — electricians, plumbers, and HVAC technicians — are frequently licensed separately, sometimes at the state level and sometimes locally. Electrical and plumbing licenses almost always require apprenticeship hours and trade-specific exams.
Because requirements differ so much, always confirm what your specific trade and license class demand with your state licensing board before you apply.
Steps to Get Licensed
Start by documenting your experience and choosing the correct license class. Next, complete any required pre-license education and register your business entity. Then pass your exams, secure your surety bond and insurance, and submit your application with fees and fingerprints. Once approved, you will receive your license and can legally bid and perform work.
