A contractor’s license typically involves a registration with the license-issuing agency and includes proving the contractor holds the minimum insurance and/or bonding as required by the municipality. Often, a license is required as a preliminary requirement for a contractor to be able to pull a permit at the local building department.

In some states and municipalities, the minimum threshold for requiring a license is based on the dollar value of the work. For instance, in New York City, any home improvement work that costs more than $200 is required to be performed by a city-licensed home improvement professional.
