Different areas have different record systems. Ours is a more rural area so the records are in County offices, whereas your records will be in a city or boro office- perhaps even a precinct office.
Depending on the age of your house, some of these records may be available to you, or anyone else, as they are public records.
Some places you might check are:
- registrar / recorder of deeds office (ask if they have a platbook or some record of land development plans. That would give you lot layout and dimensions)
-local building department, code enforcement office, etc. in some areas plans are filed for approval--probably not going to help if yours is a Queen Anne from the 1800's. :-)
-Your local REALTOR. We ( I am proud to be one!) are in the business of housing, and pick up a remarkable amount of information over the years. Find someone who has been around for a while and is active in your immediate area. If the house is a recent build, who was the builder? developer? They may also have info that would be of help.
Hope that helps!
