Marshall County Plumbing Permit Requirements

Marshall County, Tennessee, has adopted the 2018 International Plumbing Code, along with other International Codes for building, mechanical, and fuel gas. As of July 1st, 2025, they will be enforcing the 2024 versions of these codes. The Building Codes Department is responsible for ensuring compliance with these regulations.

A building permit is required for most construction, remodeling, and additions. Routine maintenance and repairs, such as painting the exterior or replacing rotten porch floors, do not require a permit. However, it is always recommended to contact the Marshall County Codes Office before starting any work to avoid potential delays.

Unincorporated Areas

For properties located in unincorporated areas of Marshall County, it is important to note that Tennessee state law requires a state residential building permit for construction in these areas if they are not within a city's limits. While Marshall County has its own set of adopted codes and permit requirements, residents in unincorporated areas should also verify if a state permit is necessary. The state requires permits for unincorporated areas in several counties, but Marshall County is not explicitly listed in the provided information regarding state permits for unincorporated areas. Therefore, it is crucial to check with both the county and state authorities to ensure all necessary permits are obtained.
