Obion County HVAC Permit Requirements
In Obion County, Tennessee, building permits are required for construction projects, including HVAC work, regardless of whether the property is within city limits or in an unincorporated area. The Obion County Assessor's Office is responsible for issuing these permits for properties outside of incorporated cities. If a city within the county does not issue its own permits, the county assessor's office handles permit issuance for those areas as well.
County-Level Jurisdiction
The Obion County Assessor's Office serves as the building and safety division for properties located in unincorporated areas of the county. They are the authority for issuing building permits when a specific city does not have its own permitting process. For properties within city limits, residents should contact their respective city's building department. The City of Union City, for example, has a Planning & Codes Department that handles permits and enforces building codes.
Properties in Unincorporated Areas
For properties situated in unincorporated areas of Obion County, a building permit must be obtained from the Obion County Assessor's Office before any construction can begin. This applies to a wide range of projects, including but not limited to pools, shops, barns, portable buildings, remodeling, roof work, and decks. While there is currently no cost for permits issued by the county, this may change in the future. It is important to note that mortgage companies often verify the existence of permits.
Additionally, any property located in a FEMA-designated flood zone, which includes areas within most cities in Obion County, will require additional permitting. Property owners in such zones will be referred to the County EMA Director for further steps.
It is important to be aware that while cities within Obion County may have their own building codes, there is generally no specific building code in unincorporated areas. However, the requirement to pull a building permit from the county assessor's office remains in effect for these areas.

State Statutes and Adopted HVAC Codes
In Tennessee, building construction safety standards, including those for HVAC systems, are authorized under Tennessee Code Annotated (T.C.A.) ยงยง 68-120-101, et seq. The state adopts minimum statewide building construction safety standards through the Tennessee Department of Commerce and Insurance, Division of Fire Prevention. As of the most recent updates, the state has adopted the 2021 editions of the International Code Council (ICC) family of codes, which include the International Mechanical Code (IMC) and the International Fuel Gas Code (IFGC) for HVAC-related installations. It is important to note that Tennessee is a "home rule" state, meaning local jurisdictions may adopt and enforce their own building codes, which may differ from the state-level standards or utilize different editions of the model codes.
Primary State Agency
The primary agency responsible for setting and enforcing these statewide standards is the Tennessee Department of Commerce and Insurance, specifically through the State Fire Marshal's Office (SFMO) and its Codes Enforcement section. The SFMO oversees the adoption of the minimum statewide building construction safety standards and provides enforcement in areas of the state that do not have local building code programs or where the local government has opted out of enforcing its own codes.
