 2019 City of Janesville Revaluation Complete

The City of Janesville Assessor's Office has completed the 2019 Citywide Revaluation. Prior to 2019, a citywide residential and commercial revaluation had not been completed since 2011. Below, please find a list of tools and frequently asked questions to assist you in understanding the recently completed revaluation process. Should you have any questions, please call the Assessor's Office at 608-755-3045.


The Online Property Search Database (eGov) and the Interactive GIS Web Mapping Service allow the general public to view specific data for all properties in the City of Janesville.

How did the revaluation affect my property?

Each property owner was mailed a notice of their property's assessment called the Notice of Assessment Change at the end of May, 2019. The notice listed what your property was previously valued at and what your new valuation is.

Why does the City have to do this?

Revaluations are used to equalize the tax base for all real and personal property on the basis of fair market value. Having all properties assessed at their current value ensures each property owner pays his or her fair share of taxes.

Will my taxes increase?

Not necessarily. Taxation is determined by the spending choices of the officials of several taxing jurisdictions. Although you pay your property tax bill to the City of Janesville, the funds from that payment are allocated to the State of Wisconsin, Rock County, Janesville or Milton School District, Blackhawk Technical College, and the City of Janesville. Once the jurisdictions decide how much funding needs to be obtained through taxes, each property owner's tax bill is developed using the assessed value of the property as the guide.

A popular tool used during the 2011 Revaluation was the “Estimated Tax Calculator”. This resource is once again available on the City of Janesville website.

Does the City consider foreclosures when determining my property's value?

The Assessor's Office only uses "arm’s length" sales when determining a property's value. "Arm’s length" transactions are only those sales that are voluntary and have independent sellers and buyers. Foreclosure properties (some of which are bank-owned) as well as sales to relatives do not generally fall under that category. In a high performing market like the one we are in today more foreclosure sales may represent “arm’s length”, but still not all of them will.

The economy has been performing well in the last few years and homes are selling quickly. Does this mean that my property will be worth more than the last time it was revalued in 2011?

Not necessarily. The chart below illustrates how the value of an average priced home in Janesville would have increased if the City had revalued property every year. However, each neighborhood has experienced different market changes since 2011. Some neighborhoods are performing better while some neighborhoods have stayed about the same.

 Who should I contact if I have questions about the revaluation process or my assessment?

You may call the City of Janesville Assessor's Office at 608-755-3045. 

How do I appeal my 2019 assessment?

The opportunity to appeal 2019 assessments has passed. If you felt your 2019 assessment was a reasonable estimate of the Fair Market Value of your property, the first step available was to discuss it with your municipal assessor during the Open Book period. Open Book was when proposed assessments were first printed and made available for citizen review. During Open Book, which was held from June 6-June 26, 2019, assessment staff was available to meet with property owners to answer questions and exchange information in order to detect any errors or omissions in property data, which may or may not have result in an assessment change.

How do I appeal if I still do not agree with the results of my Open Book meeting?

The next step that was available has also passed, which was to attend the 2019 Board of Review hearings, which began on Monday, August 5, 2019. 

Note: Not receiving a Notice of Assessment Change or attending an Open Book meeting does not disqualify someone from appealing their assessment to the Board of Review. If you desire to appeal your assessment in any year, your appearance at that year's Board of Review hearing is extremely important. Most subsequent appeals require that you first attend the Board of Review. Therefore, always verify your assessment annually prior to the Board of Review. The entire appeal process is fully explained in the Wisconsin Department of Revenue’s "Property Assessment Appeal Guide for Wisconsin Real Property Owners". Additional Property Tax information may be found on the Department of Revenue Website.

Pursuant to 2009 Wisconsin Act 68 (Effective 11-25-2009):


2020 Annual Property Inspection and Valuation Process

The City of Janesville is conducting its annual property inspections and valuation procedures for the 2020 assessment roll.  As part of that effort, we will be conducting exterior and interior inspections on a limited number of properties throughout the City of Janesville until such time that we have completed the 2020 assessment roll (estimated to be completed by mid-summer 2020). In accord with Wis. Stats., SS943.13 and 943.15, the Assessor and members of an Assessor's staff may enter land of another (other than a building, agricultural land or pasture or livestock confinement area) or construction sites without trespassing if the following apply:

  • The assessor or assessor's staff enters the land in order to make an assessment on behalf of the state or a political subdivision.
  • The assessor or assessor's staff enters the land on a weekday during daylight hours, or at another time as agreed upon with the land owner.
  • The assessor or assessor's staff spends no more than one hour on the land.
  • The assessor or assessor's staff does not open doors, enter through open doors, or look into windows of structures on the land.
  • The assessor or assessor's staff leaves in a prominent place on the principal building on the land, or on the land if there is not a principal building, a notice informing the owner or occupant that the assessor or assessor's staff entered the land and giving information on how to contact the assessor.
  • The assessor or assessor's staff has not personally received a notice from the owner or occupant, either orally or in writing, not to enter or remain on the premises.

An owner has the right to deny either orally or in writing the assessor or assessor's staff access to the property.  Should that occur, Wis. Stat. SS 70.05(4m) requires that "Each taxation district assessor shall create and maintain a database identifying all such property owners in the taxation district."

Wisconsin Statute Section 70.32 outlines the value of real property shall be based on “actual view". To ensure receiving a complete and accurate valuation, it benefits the homeowner to provide interior viewing access of their residence. If an assessor is not allowed access to view a property, property value is based on “the best information that the assessor can practicably obtain…” For the purposes of valuation, if access is denied, the assessor must estimate the property value using the information they have available to them. However, if facts exist that make an interior view necessary to complete an accurate valuation, per Wisconsin Statute Section 66.0119, the assessor may seek a Special Inspection Warrant to view the interior of the home.

Wisconsin Statute Section 70.05(4n) requires the following notice:

You have the right to refuse entry into your residence pursuant to Section 70.05(4m) of the Wisconsin Statutes. Entry to view your property is prohibited unless voluntarily authorized by you. Pursuant to Wisconsin Statute Section 70.05(4m), you have the right to refuse a visual inspection of the interior of your residence and your refusal to allow an interior inspection of your residence will not be used as the sole reason for increasing your property tax assessment. Refusing entry to your residence also does not prohibit you from objecting to your assessment pursuant to Wisconsin Statute Section 70.47(7).
