Converting an existing building into a dwelling is a change of occupancy that needs a state building permit where the state residential program applies. That covers a detached garage turned into a separate living unit. Cities and counties that enforce their own residential code decide whether an attached garage conversion needs a building permit, and it commonly does. Confirm with your local codes office. Where the state code applies, residential energy rules come from the 2018 IECC or Chapter 11 of the 2018 IRC, as adopted with Tennessee amendments.
