Frequently Asked Questions
Do I need a building permit for a garage conversion in Ohio?
Yes. Most Ohio jurisdictions require a general building permit for 'change of use' from a garage to habitable space, plus separate trade permits for electrical, plumbing, and HVAC work.
How much does a garage conversion cost in Ohio?
In 2024-2025, a standard conversion in Ohio ranges from $15,000 to $45,000. Basic room finishes may start around $8,000, while full studio apartments with kitchens and baths can exceed $50,000.
Can I keep the original garage floor?
While the slab stays, the RCO requires habitable floors to be insulated. In Ohio, you typically must build a sleeper floor with a vapor barrier or add rigid foam insulation and a new topping to prevent moisture and cold-seep.
Is heating mandatory for the converted space?
Yes. Under Ohio code, habitable rooms must be capable of maintaining a minimum temperature of 68°F. You may need to extend your existing HVAC ductwork or install a ductless mini-split system.
