Whether you’re in the process of planning your dream project or need an emergency fix, understanding and checking licensing is a vital part of the hiring process—and the requirements for contractors vary depending on where you live.
Some states issue licenses for general contractors, while others only require them for specialty trades. Cities and counties can also require their own set of credentials.

This tool and guide will help you determine licensing requirements at the state level. We recommend continuing your research by contacting your local government to confirm your pro meets city and county licensing requirements.
State Contractor Licenses
Each state has its own regulations and guidelines around contractor licensing, and counties and cities may have additional requirements, too. Before you commit to hiring a general contractor, start your research process here. Then, make sure your chosen pro meets all of the criteria and has the appropriate licenses.
What is a General Contractor License?
A general contractor license is a state or local government-issued license that ensures the contractor meets the city's, town's, or state's requirements for working on residential and commercial construction projects. Licensing requirements vary widely by state, county, and even city. For instance, some states may require no licensing for general contractors or may only require a license for general contractors who work on projects valued at more than $1,000. Many licensing bodies require pros to have the appropriate general contractor insurance and provide references, accountant-prepared financial statements, and proof that their business is appropriately registered. In some locations, general contractors may have to pass a written exam.
Subcontractor & Niche Contractor License Requirements
Some specialty trades, including subcontracted and niche work, require their own set of licensing. For example, heating, venting, and cooling (HVAC) pros need a state-issued license in many states. With few exceptions, the same is true for electricians and plumbers, regardless of project type. Conversely, handypeople typically don’t need a license, but some states require it.
Structural Engineers & Architect Licenses
Structural engineers and architects have different areas of expertise, even though they’re both rooted in civil engineering and work on building projects. Generally, structural engineers focus more on function and durability, while architects consider aesthetics. Both have many years of formal education under their belt, and both typically need a license to work in the United States.
Licenses vs. Certifications
Though both are a type of credential, typically, a government body will issue a license, which gives the person who carries it the legal right to practice that type of work. States may also require or issue certifications, which indicate a person has completed the necessary work or education to practice their specialty.
How Do Contractors Become Licensed?
Depending on location, contractors may need to pass an exam, register their business with the state, get liability insurance, or some combination. Licensing legitimizes a contractor’s business and, in many cases, legally protects them from liability and fines due to issues that may occur on a job. In some places, contracting without a license can prevent a potential pro from ever getting one.
