For the 12 months following this transition, constituents who call the Office’s prior phone number will automatically be transferred to our new line.

The Assessor is required to assess the property at its current market value when a change in ownership occurs.  This usually results in an increase in property taxes.  However, there are some changes in ownership that are excluded from reassessment.
