My question involves court procedures for the state of: Ohio

I'm residing in Cleveland Ohio. I'm having some landlord problems. The landlord is harassing me with threats of unlawful eviction.

My question is --

What is typically the jurisdiction of a municipal housing court in a city? For instance, Cleveland Municipal Housing Court. Over what defendants would they have jurisdiction?

Is it just people in Cleveland? Or could people from another municipality have jurisdiction?

Also, over what government organizations would they have jurisdiction? For instance, would they have jurisdiction over a federal government official? Would they have jurisdiction over a city government official?

Thanks in advance!
