Deck Permit Requirements in Hamilton County, IN
Do You Need a Deck Permit in Hamilton County?
Yes. In virtually every jurisdiction in Hamilton County, building a new deck or making significant modifications to an existing deck requires a building permit. This applies to attached decks, detached decks, and elevated decks.
Minor repairs — such as replacing damaged boards with the same material — typically do not require a permit. However, if you’re changing the footprint, height, or structural design, you need one.

- Setback compliance — Your deck must meet minimum setback distances from property lines. These vary by jurisdiction and zoning district.
- Footing depth — Indiana requires footings to extend below the frost line (typically 36 inches).
- Railing requirements — Decks 30 inches or more above grade require a railing at least 36 inches high with balusters spaced no more than 4 inches apart.
- Ledger board attachment — For attached decks, proper ledger board connection to the house is critical and will be inspected.
- Load-bearing capacity — Structural plans must show the deck can support required live and dead loads per code.
Inspections
Deck construction in Hamilton County typically requires at least two inspections:
- Footing inspection — Before pouring concrete for footings
- Final inspection — After the deck is fully built, including railings and stairs
Cost Savings Tips
- Prepare complete plans — Incomplete applications cause delays. Include all dimensions, materials, and structural details.
- Check your HOA — Some homeowners associations have additional requirements beyond the building code.
- Know your setbacks — Call the local planning department to confirm setback requirements for your specific lot before designing your deck.
- Consider a permit expediter — If you’re building a complex deck or on a tight timeline, a local expediter can handle the paperwork.
