Property Tax Assessment Freeze

Benjamin Historic Certifications helps owners of historic homes receive a freeze on their property tax assessments.

In 1983, the State of Illinois passed a statute enabling homeowners who rehabilitate their landmark property to receive a freeze on their property tax assessment for eleven years. This is called a "certified rehabilitation."

What is a Landmark property and therefore eligible for the Property Tax Assessment Freeze?

  • A building individually listed on the National Register of Historic Places
  • A Contributing building in a National Register Historic District
  • A building locally designated as a Landmark
  • Contributing buildings in a locally designated Historic District
  • Lakeview National Register Historic District, ChicagoThere are many designated landmark houses and Historic Districts with buildings that are eligible to receive the Property Tax Assessment Freeze. These landmark buildings and historic districts are located in Chicago and the city's suburbs as well as throughout Illinois. Individual buildings and areas may be nominated for landmark designation by Benjamin Historic Certifications so that a property may qualify for the assessment freeze.
