Do Indiana jurisdictions agree?
Every row below is a measurement at least two Indiana jurisdictions publish, compared against each other. This is the question a statewide answer cannot settle, because the number that governs your project is the one your own city or county publishes.
| Project | Published threshold | Jurisdictions | Agreement |
|---|---|---|---|
| Shed | 120 to 200 sq ft | 2 | 2 different numbers |
0 of 1 comparable measurements are uniform across Indiana; 1 are not. Latest verification 2026-08-15.
Where Indiana jurisdictions split
The verdict for each project across the 2 Indiana jurisdictions we cover. On 4 of 10 projects they do not give the same answer, which is why a statewide answer is not one.

|---|---|---|---|---|
| Deck | 1 | 1 | Answer varies | |
| Fence | 1 | 1 | Answer varies | |
| Pool | 1 | 1 | Answer varies | |
| Roof Replacement | 1 | 1 | Answer varies | |
| Electrical | 2 | Same answer everywhere | ||
| HVAC | 2 | Same answer everywhere | ||
| Patio | 2 | Same answer everywhere | ||
| Plumbing | 2 | Same answer everywhere | ||
| Shed | 2 | Same answer everywhere | ||

Building without a permit in Indiana
Indiana splits buildings into two classes and only one of them carries a statewide permit offense. For a Class 1 structure (commercial, public, three or more tenants), building with no state design release is a Class C infraction under IC 22-15-3-7(c), and a Class C infraction carries a judgment of up to $500 under IC 34-28-5-4(c).

What each Indiana jurisdiction publishes
One line per jurisdiction, written from its own rules rather than from a state summary. This is the section that used to be a list of links, and the states with the fewest jurisdictions to compare are the ones it says the most about.
