Newton County, Mississippi Plumbing Permit Requirements

Plumbing Codes and Legislation in Mississippi

In Mississippi, plumbing standards are primarily based on the International Plumbing Code (IPC), published by the International Code Council (ICC). While the state provides a framework for these standards, the adoption and enforcement of specific code editions are often handled at the local level. Many jurisdictions in Mississippi have adopted the 2021 edition of the International Plumbing Code as their technical baseline, often incorporating state-specific amendments to address regional needs, such as hurricane and wind resilience in coastal areas.

It is important to note that Mississippi does not mandate a single, uniform statewide adoption of the I-Codes for all counties and municipalities.
