Deck Construction · Johnson County, Indiana
Permit required
In Indiana, a Deck Construction requires a building permit.
The only exception is a small freestanding platform 200 sq ft or smaller and no more than 30 inches above grade that is not attached to the house (IRC R105.2); any attached or elevated deck needs a permit. Plans are reviewed under the Statewide code (IRC 2018); apply through Johnson County Planning/Zoning before work begins.

Building a deck typically requires a permit if it is attached to the house, over 30 inches off the ground, or exceeds a certain square footage (often 200 sq ft).
With a population of around 166,315 residents, Johnson County generally runs a more streamlined permitting process than major urban hubs.
Code Compliance & Inspections
Because of severe winter weather in Indiana, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Indiana Building Code.
Concurrent Permits & HOAs
For Johnson County residents, we highly recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Often, homeowners associations maintain stricter rules regarding materials and dimensions for your Deck Construction than the county itself.
Zoning & Cost Factors
Indiana law grants substantial zoning power to local plan commissions, with a strong emphasis on balancing residential expansion with agricultural land preservation. Fortunately, Indiana maintains relatively builder-friendly regulations, keeping base permit fees competitive.

Frequently Asked Questions
What happens if I build a Deck Construction without a permit in Johnson County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.
Can a homeowner pull their own Deck Construction permit in Indiana?
Yes. Indiana generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Indiana Building Code.
How much does a Deck Construction permit cost in Johnson County?
Permit fees vary by jurisdiction and by your project's valuation, so Johnson County does not publish a single fixed figure. Confirm the exact fee with the local building department before applying.
How long does it take to get a Deck Construction permit in Johnson County?
Based on the size of Johnson County, the typical processing time is 10 to 14 business days. Times vary with the season and the building department application volume.
