Resources to Research the History of Your House

These are some suggestions for researching your house. We recommend that you begin your research at the Nassau County Clerk’s Office.

The Nassau County Clerk maintains a record of real estate transactions and makes them available to the public. The office is responsible for:

  • Recording deeds, mortgages, and mortgage satisfactions.

  • Computing, collecting and disbursing transfer and mortgage taxes.

  • Providing certified copies of recorded documents.

  • Recording commercial chattel mortgages, building loans, and their dispositions.

  • Maintaining county land and subdivision maps.

Finding information at the Clerk’s office will be easier if you know the section, block, and lot numbers (the numerical code as established by Nassau County that designates your parcel) of your house. This information is available on your tax bill and My Nassau Property.

My Nassau Property:

This site allows you to search by address. The “Property Description” section provides you with the block, section, and lot numbers of your house. This section also includes: the year the house was built and year it was remodeled; style of home (bungalow, ranch, old style); square footage; and lot size. You can also view aerial photographs of your house and neighborhood. (Please note: there are errors in some of the descriptions. When possible, verify the information using other sources).

Additional Resources:
