Do I need a permit for addition or structural alteration in Unincorporated Clay County?
Unincorporated Clay County does not issue residential building permits. Clay County has no county building department and issues no residential building permit. The Indiana Department of Homeland Security (IDHS) Local Building Officials directory (printed 9/27/2026) lists no local building official for the unincorporated county, only the IDHS state inspector, who handles Class 1 (commercial) structures; the state does not issue permits for one- and two-family dwellings. The state residential code still applies to the work. Contact the county office listed here with questions.
The requirements below come from Indiana rules and describe the standard the work must still meet. They are not a statement that Unincorporated Clay County will issue you a permit.
Most likely yes. Addition or structural alteration usually requires a permit in Indiana. Confirm the specifics with Unincorporated Clay County.
IC 36-7-2.5 sets statewide rules for any city, town, or county that requires Class 2 permits: plan review must be completed within 7 business days after the unit confirms the application is complete, and the owner may use a qualified private provider for plan review or inspection. A local unit may not require an architect or engineer to prepare plans for a Class 2 structure built as prescribed by the 2020 Indiana Residential Code (IC 36-7-2.5-35). Under Indiana's amendments to R314.2.2 and R315.2.2, additions and alterations that require a permit trigger smoke and carbon monoxide alarms as required for new dwellings, with listed exceptions; sprinklers cannot be required in Class 2 structures (IC 22-13-2-3.5). The state does not issue permits for or inspect one- and two-family dwellings; if the local unit has no building permit ordinance, no state office issues one instead, but the 2020 Indiana Residential Code still applies to the work.
