These are the tax maps used by the Erie County Auditor. They are indexed by city and township and generally cover 1920-1986 although some cover 1900-1986. Use the Index file to locate the section you are interested in and then click that section number to view the particular plat map. These are large PDF files and can take up to one minute to fully load. The maps show the owner names and lot lines. Every so often these maps are retired, new maps are drawn and put into place and ownership is once again tracked. This is a great tool for locating previous owner names. Current maps are physically located in the Erie County Office Building in the Tax Map room.
