📢 Notice from the Carroll County Assessor’s Office 📢

Appraisers from the Carroll County Assessor’s Office will be working in communities across the county over the coming weeks. These visits are part of our annual duties to review new construction and verify any demolition activity.

Per Iowa Code § 441.17(9), county assessors and their deputies are authorized to enter real property for assessment purposes, including measuring and inspecting buildings.

What to expect:
✅ Appraisers will always knock on the door before beginning any exterior work.
✅ If no one is home and no “No Trespassing” sign is posted, exterior measurements may be taken from accessible areas only.
✅ Walk-throughs of new construction will only occur with permission.
✅ If a property owner asks an appraiser to leave, or if access is restricted/posted with “No Trespassing,” the appraiser will leave immediately and note the visit.

Our staff will always conduct themselves in a respectful and professional manner and will work to minimize any disruption.

If you have questions, please contact the Carroll County Assessor’s Office at (712) 792-9973.

Thank you for your cooperation in helping us keep assessments accurate and fair for all property owners.

Carroll County Assessor’s Office is announcing that door-to-door inspections of all commercial, industrial, and 3+ residential properties in Carroll County will begin approximately May 5^th, 2025.

A reappraisal project was approved by the Conference Board in February 2022.

The purpose of the reappraisal project is to equalize property assessments so that each taxpayer is responsible for paying only his/her fair share of the property tax burden.  Periodic inspections and reappraisal of properties are necessary as all types of properties do not increase or decrease in value at the same rate. Some properties physically deteriorate faster than others, and in many instances similar homes located in different areas of the county will differ greatly in value due to economic factors.

Data collectors with photo ID’s signed by the Assessor will attempt to make interior and exterior inspections of all commercial, industrial, and 3+ residential properties.  They will be compiling information to be used to estimate the fair market value of each property.  Information to be collected includes type of construction, type of interior finish, physical condition of the property, age of structures and exterior measurements.  A complete sales analysis, local construction costs, and economic conditions are also considered.  No estimate of value will be given at the time of inspection.

Property owners are asked to cooperate by allowing a complete inspection of their property and providing accurate information so that a fair and equitable assessment may be determined for each property.

The preliminary data collection process will begin in May 2025.  The project is scheduled for completion December 31^st, 2026.

Notice of final value estimates will be mailed to each property owner after January 1, 2027.  The property owners will have an opportunity to meet informally to discuss their revaluation in the spring of 2027.

The new assessed values will be effective for January 1, 2027, for taxes payable in fiscal 2028-2029.

Representatives of Vanguard Appraisals, Inc., in conjunction with the Carroll County Assessor’s Office will be conducting this project.

All law enforcement agencies as well as the Carroll County Assessor’s Office will be apprised of the areas where data collectors are working.  They will also have a list of all the names and license plate numbers of anyone involved in the project.

If any property owner has questions regarding the reappraisal project, they are urged to contact the Carroll County Assessor’s Office at 712-792-9973 or email: shaberl@carrollcountyiowa.gov
