Plumbing Permit and Inspection Program

The mission of the plumbing program is to carry out and enforce the Delaware plumbing code in conformance with basic plumbing principles and regulatory requirements.

The program accomplishes its mission by providing for the adoption and promulgation of suitable rules and regulations for the construction of plumbing facilities where mandated. Program staff oversee registration of plumbers and others involved in the plumbing business in Delaware. The program provides a mechanism for the issuance of permits whenever plumbing takes place, enforces plumbing codes and regulations, handing down penalties when appropriate.
