Columbus Garage to ADU conversion

[Mike Hasson]

Hi! I'm about to start making offers on properties in Columbus but first want to make sure my plan is reasonable. My plan is to purchase a home to house hack with a detached garage, convert it to an ADU, and live in the ADU while I rent out the main house.

I can find a ton of info for doing this in California, but not as much in Ohio - so I'm wondering:

How common/accepted are garage conversions in the Columbus area?

Has anyone here competed a conversion like this in/around Columbus? Is there anything you wish you knew before doing it? What was the cost and about how long did the project take to complete, including planning and permitting?

Any insight would be helpful to make sure my plan is realistic before I give up everything to move out there lol

Thanks!
