a consumer, it is beneficial to check a contractor's license number before allowing
work to be done on your project:
Building Codes Division issues licenses
to four types of trade contractors: electrical contractor, elevator contractor,
plumbing contractor, boiler contractor. Every trade contractor must also possess
an active Building Contractor license issued by the Construction Contractors Board
(CCB). It is a good idea to check the status of both licenses before allowing
work to be done on your project.
