Welcome to OnCOR
Ontario County welcomes you to OnCOR (Ontario County Online Resources). OnCOR is a cooperative project between the Ontario County Planning Department, Real Property Tax, Information Services, and the County Clerks Office. OnCOR leverages the resources of these individual departments and delivers them through one common web enabled interface.

This project currently provides integration of County’s Land Record information (assessment data, deeds, surveys, aerial photography), and will evolve to address the needs of the Ontario County Tax Payers. In its current form this application provides a rich set of tools that can be immediately used as resource enhancing Ontario County’s service delivery.

Welcome you to OnCOR and invite you to begin exploring its many uses.
