I am trying to determine which residential real estate parcels are sub-dividable but am running into issues when it comes to placement of an already existing structure on a parcel.
For example, let's assume the minimum requirements to create a new parcel is 10,000 square feet with 50' of frontage along the road. I can calculate parcels that have at least 20,000 square feet with at least 100' of frontage and know that those parcels may be sub-dividable. However, if an already existing structure is right in the center of said parcel then it is no longer sub-dividable without demolishing the structure.
How can I take into account the location of existing structures on a lot to see if the empty space between the structure and lot boundaries are sufficient to sub-divide?
