What you need to do the work

For homeowners:
Do I need a plumbing permit?
Do I need a mechanical permit?
Do I need an electrical permit?
Do I need a structural permit?

As 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.

General contractor's license from Construction Contractors Board (CCB).
