How to read a page

A lot is not a buildingA deed is recorded against the ground. One lot can carry several buildings, and every price says which it covers.
Zoning is about the groundIt describes what MAY be built on a lot, which is frequently not what is standing there now.
Not every price is a saleA recorded consideration of ten dollars or less is a transfer. Those are shown, labelled, and never headlined.
