Real Property Listing and Addressing

For assessment questions or disputes, contact your local assessor to review your options. Check the Wisconsin Municipal Assessors List.

• Town properties: Parcel combines must follow the Outagamie County Land Division & Platting Ordinance. A Certified Survey Map (CSM) is required. Learn more about the CSM process(PDF, 479KB).

• City/Village properties: Properties located within a City or Village may combine/split a parcel or parcels with approval from your Municipal Clerk and your local Assessor. A letter signed by the Municipal Clerk and ALL owners of the parcel or parcels can be emailed to the Real Property Lister. Changes are processed for the next tax roll year (e.g., a request received June 10, 2023 appears on the 2024 tax bill). Contact your Clerk/Assessor about potential assessment impact.

Visit the Outagamie County Ascent Land Records site, search your property (parcel ID, address, or name), then click on "Find Now". Choose the correct record under display to view details.

Contact your local Assessor for questions about your assessment.

Prior-year assessment and tax rolls are available on the Outagamie County Open Data site. Current-year rolls are posted in January of the following years (e.g., 2023 rolls in January 2024).

Property owners who want to request a new address must contact their municipality.

Municipalities in the unincorporated areas of Outagamie County (except the Town of Grand Chute) and in the Villages of Nichols and Shiocton will submit the new address request on the property owner's behalf online via CityView Web Portal. All other municipalities in Outagamie County have addressing authority and will process new address requests according to their local procedures.

To change a parcel mailing address, visit the Outagamie County Ascent Land Records site, search your property, and select "Request Mailing Address Change". Updates may take up to 24 hours to appear.

More information about this process is available through the County Treasurer "Mailing Address Change" webpage.
