Hi I Currently have an opportunity to purchase a single-family residence that has a detached ADU (1B/1B). The basement has full kitchen, 2b/2b and already has a dedicated exterior entrance. If I purchase the home my plan would be to convert the basement to it's own dedicated unit by installing a interior wall which would separate the main floor from the basement so the exterior entrance would be the only way to access the basement with it's own dedicated path on the outside of the property. Does anyone have any experience within Indianapolis in terms of what the overall process would look like to do this and is it even worth legitimizing the basement as a separate unit?

The benefits I see is the home would go from a single-family to a multi-unit property increasing the value with a re-appraisal.
