3 lots sold as one parcel?

[Rich Bultema]

I'm looking at a house for sale in an old part of town. The county website states the legal description of the parcel as something like "subdivision blah blah blah lots 33, 34, and 36"

Three equal sized/shaped lots that forms an L shape where the house and garage are on two of the lots with frontage on "Oak" street and the third lot has no structures and its own frontage on "Maple" street.

What are my possibilities that I could purchase this property and separate out the third lot to either sell by itself or potentially build on? How does that work?

Thanks
