Do You Need to File?

To determine if your project may be exempt from filing with the state, please send an email to planreview@dhs.in.gov. Give a detailed description of work to be performed as well as city and county where the work will take place. 

The decision chart here is intended to be an aid in determining whether Indiana law requires you to file your project with the state of Indiana. As always, IDHS recommends you contact a construction design professional to ensure compliance with all Indiana laws. 

• If one scope is required to be filed, then all scopes must be filed.

• All work must comply with all applicable codes whether or not it is required to be filed.

• All work, including that exempted from filing with the state, may require local permits.
