In Ohio it depends on the township's zoning. Some townships in Ohio have no zoning. There are basic guidelines that the state has in place that must be adhered to.
Our township, and some of the surrounding ones have some weird zoning laws. For example, if you own a parcel of land, you cannot construct outbuildings or accessory buildings, such as garages or barns, unless there is a house on the property. I asked the township trustees why they had this law. They said they were afraid someone would put up a building and use it for storage.
I said, "So,what if a person has a house, then puts up a building and uses it for storage?" He said that would be OK.
I own a 1.25 acre lot across the street from my house. I plan on putting an RV pad and septic system in. Our current plan is to sell the house upon retirement, and spend the winters in FL, then come "home" to Ohio for the summers. The taxes on this parcel are only $400 a year. But, they keep going up.
My advice is to check LOCAL zoning laws before you purchase a piece of property.
