Concur with Gail. Generally, the landlord will be given anywhere from 7 to 30 days to cure the issues. In the state of Ohio, 30 days is the absolute maximum the landlord is allowed to fix the issues.

To move things along, I would suggest you head down to the Clerk of Courts and make arrangements to escrow your rent. That tends to light a quick fire under a landlord's butt and make him move faster.
