How to file a 2023

Board of Review Appeal

We are available by phone or in person to discuss an appeal with you.

Deadline to file an appeal is February 6th

Unless you have specific evidence to add to an appeal, you can request an appeal by calling our office or by using the link below.

An appeal is intended to correct the accuracy

of your property’s assessment.

If the value of your property is assessed higher per square foot than other similar properties, you can file an appeal based on the grounds of Lack of Uniformity.

If you recently purchased your home in an arms length transaction for less than the County Assessor’s Current Market Value, you can use your closing documents as evidence to support a reduction in the assessment of your home.

If the County Assessor’s market value is higher than similar recently sold homes, you may use this data as evidence to support your claim of over assessment.

Please click the button below if you would like to request an appeal. If you already requested an appeal in November, please do not fill out the form again.
