Mercer County's Planning Department is involved in the review and approval of various development applications, including subdivisions and site plans, particularly those that may affect county roads, property, or drainage facilities. While the county has specific requirements for land development and right-of-way occupancy permits, the direct issuance of plumbing permits for individual properties is typically handled at the municipal level.
For properties in unincorporated areas, the permitting process will generally follow the regulations of the nearest municipality or the county's designated authority for such areas. New Jersey's Uniform Construction Code (UCC) provides a framework for construction permits, which include technical subcode applications for plumbing work. These permits are usually issued by municipal construction or code enforcement offices.
Key requirements for obtaining a plumbing permit in New Jersey include:
- Completing the UCC-F100 Construction Permit Application and the F-130 Plumbing Subcode Technical Section.

New Jersey Plumbing Legislation, Codes, and Guidelines
Plumbing Codes and Legislation in New Jersey
In New Jersey, plumbing standards are governed by the state's Uniform Construction Code (UCC), which is codified under N.J.A.C. 5:23. The specific plumbing requirements are detailed in the "Plumbing Subcode" (N.J.A.C. 5:23-3.15). Rather than utilizing the International Plumbing Code (IPC), New Jersey has adopted the 2021 edition of the National Standard Plumbing Code (NSPC), published by the International Association of Plumbing and Mechanical Officials (IAPMO). This model code is adopted with specific state-level amendments to address New Jersey's unique requirements regarding materials, installation practices, and safety standards.
Primary State Agencies
The primary state-level agency responsible for the adoption, administration, and oversight of these construction standards is the New Jersey Department of Community Affairs (DCA), specifically through its Division of Codes and Standards. While the DCA sets the statewide technical standards and oversees the regulatory framework, the actual enforcement—including the issuance of permits and the performance of inspections—is carried out by local municipal construction offices. Additionally, the licensing of plumbing professionals is managed separately by the New Jersey State Board of Examiners of Master Plumbers, which operates under the state's Division of Consumer Affairs.
