Building Permits & Inspections


 If you are planning a home improvement project you may be wondering, “Do I need a permit?”

The Town of Thorntown has adopted the Indiana State Building Code. This code was revised in 2020.  Under that Code, building permits are required to construct, add onto, alter, remove, demolish or repair a structure.  Examples of projects that require a permit are; basement finishes, re-roofing, re-siding, some electrical replacement or upgrades, windows, garages, sheds, decks, fences, furnaces, gas fireplaces, air conditioners, etc.

A permit ensures that proper services are provided to safeguard life, health, general public welfare and property values.  Through the permit process, Town staff will review permitted construction work and installations to ensure that they are done safely and in accordance with current requirements.  Regular inspections during construction not only can reveal minor problems that could avert costly repairs, but may also identify life-safety concerns.

In advance of when you wish to begin work, submitting all the required information about your project along with the permit application form will help to ensure a timely review and permit issuance.  We have provided an online, fillable form document to make the permit process as easy as posibble. Click Here to access the Building Permit Application Fillable PDF form. 

Some projects may not require a building permit; however, they may require a zoning permit.  Examples of these projects are; fences, sheds over a specified square footage  and unattached decks less than 30 inches in height.
