Each state in the USA has different levels of education and training and distinctive requirements for getting a license for plumbers.

Delaware requires a plumbing license for any person or organization that is engaged in any sort of plumbing activity, so you will not be allowed to work unless you have it.

You can become a journeyman or master plumber for an organization or a general contractor.

But, in order to become a state-licensed general contractor in Delaware, you will comply with the Delaware Department of Revenue.

In Delaware, there are two different types of contractors:

  • Non-Resident Contractor License, that is, an individual or business that performs contractual work and maintains the majority of that work outside the state of Delaware. Non-Resident Contractors must also be able to supply a surety bond;
  • Resident Contractor License: an individual or business that performs contractual work and maintains the majority of that work within the state of Delaware.

Delaware Plumbing License Reciprocity

Unlike some other states, Delaware offers some reciprocal agreements within the state.

This means that if you hold a current plumbing license in Connecticut, Iowa, and Maryland, Delaware extends a license reciprocity agreement.

The following states also will consider a reciprocity agreement with proof of experience under a licensed professional:

  • Alabama
  • Arkansas
  • District of Columbia
  • Florida
  • Georgia
  • Michigan
  • New Hampshire
  • New Jersey
  • North Carolina
  • Ohio
  • Rhode Island
  • South Carolina
  • Virginia
  • West Virginia.

Ultimately, the board will decide whether or not to honor some sort of agreement.
