Welcome to the new online home of the
Rockford Township Assessor's Office

This website is designed to be a useful source for over 70,000 taxable parcels located within Rockford Township. I hope you find it helpful for practical information about specific properties and the assessment process in general.

Each taxpayer deserves the best possible service at our office and over the internet. 
I appreciate and seek your comments and suggestions about our service and ways to improve our website. Please let me know what you think by calling or sending me an email.

Ken Crowley
 Respectfully,



Ken Crowley
