Assessment Department

About the Assessment Department

The City of Yonkers Assessment Department is a team of appraisal, technical and administrative professionals, responsible for establishing the assessed value for all property within our municipal boundaries. As property tax professionals:

  • The Assessment Department produces an annual Assessment Roll reflecting change in property condition, ownership, boundaries, and exemption status.

  • The Assessment Department strives to ensure the most equitable results from Board of Assessment Review, Small Claims Assessment Review and Certiorari challenges.

  • The Assessment Department provides property information to the general public, private industry and government entities.

By performing these functions within the confines of NYS Real Property Tax Laws and Rules for Real Property Tax Administration and the Administrative Code of the City of Yonkers, the City of Yonkers Assessment Department establishes the base for the city's largest annual revenue source.
