Overview

In Mississippi, building code adoption is managed at the local level, but the state provides recommended codes that jurisdictions can choose to adopt. The Mississippi Building Codes Council has adopted the 2018 editions of various International Codes, including the International Residential Code (IRC) and the International Plumbing Code (IPC). However, local jurisdictions are not required to adopt these codes and may choose the 2018, 2015, or 2012 editions or opt out entirely.

For electrical standards, the 2014 National Electrical Code (NEC) was adopted statewide, becoming effective on May 1, 2017. However, as the 2014 NEC is not readily available, the 2017 NEC is used for answers where applicable. Mississippi does not enforce a mandatory statewide energy code, and jurisdictions may adopt stricter building and fire codes if desired.

Hybrid Adoption

A hybrid adoption system means codes can vary at state and local level. Many times the state establishes a base code for building regulations and local jurisdictions then have the authority to amend or adopt more stringent requirements. This allows flexibility for cities and counties to tailor codes to their specific needs while maintaining a foundational standard set at the state level.
