Tennessee, Lewis County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Lewis County HVAC Permit Requirements
Lewis County, Tennessee, does not have its own building and codes department. For building and code-related information, it is recommended to contact the City of Hohenwald. However, for properties located in unincorporated areas of Lewis County, the county itself does not require a building permit for any type of structure or size, whether for residential or commercial use. This applies to new construction and additions like emergency backup power generators. While Lewis County does not have specific ordinances for septic tanks or electrical installations, Tennessee State Law (Tennessee Code Annotated or TCA) does mandate requirements for these aspects.
For HVAC permit requirements specifically, most HVAC installations, replacements, and major repairs in Tennessee necessitate a mechanical permit from the local building department. However, since Lewis County has opted out of having its own codes department, the jurisdiction for permits in unincorporated areas may fall under the state or the City of Hohenwald, depending on the specific circumstances. Generally, projects costing less than $25,000 are regulated at the local level, and it is advisable to contact the specific county or city where the work will be performed.
It's important to note that a state HVAC contractor license does not exempt one from local permit requirements.
Rules for Properties in Unincorporated Areas
In Lewis County, properties situated in unincorporated areas outside the city limits of Hohenwald generally do not require a building permit from the county for any type of structure or use. This includes new construction and additions such as emergency backup power generators. While the county itself does not have specific building and codes enforcement, Tennessee State Law does outline requirements for septic systems and electrical installations.
For HVAC work in these unincorporated areas, the situation is less clear due to the county opting out of a codes department. While local jurisdictions typically issue permits for HVAC work, the absence of a local Lewis County codes department means that enforcement may default to the state or the City of Hohenwald. It is recommended to contact the City of Hohenwald for guidance on any potential permit requirements for HVAC work in unincorporated areas, as they handle codes for the city and may be the point of contact for surrounding areas.
