What is the difference between A contractors and B contractors?

A contractors (also called Class A) are licensed to work on large-scale projects like commercial buildings, multi-family units, or anything involving complex structures and systems. They can build from the ground up, including high-rise buildings, shopping centers, and big apartment complexes. A contractors have to meet higher experience and qualification requirements.

On the other hand, B contractors (Class B) are general building contractors who typically handle residential or smaller commercial projects. They can build homes, remodel buildings, and manage construction where at least two unrelated trades are involved (like Plumbing and electrical). However, they usually can’t take on massive structural work unless it falls under their license scope.
