Assessing Office

The Assessing Department is responsible for the inventory of all property within Ada Township and the valuation of all of its taxable property. The Assessing Office maintains records of current ownership, assessed and taxable values, property characteristics and market data. The Assessing Department follows the requirements of the General Property Tax Law of the State of Michigan.

Please feel free to stop in or call (616) 676-9191 ext. 26 if you have any questions about your property. The assessing system is quite complex, and we are always willing to help our taxpayers understand how the system works.

  • True Cash Value: The estimated market value of your property.
  • Assessed Value: One half of the true cash value. The Assessor is not permitted by State Law to set your new assessment at one-half of your purchase price. Annual changes of assessment are based on sales in the neighborhood. Ada Township has at least 54 sales neighborhoods. Your neighborhood rarely consists solely of the homes located on your street. It is your responsibility as a taxpayer to review your Property Record Card periodically to be sure you agree with all the information that is currently of record.
  • Taxable Value: The value capped by Proposal A that is multiplied by the millage rate to calculate your tax bill. Your taxable value can never exceed your assessed value.
  • Principal Residence Exemption: An 18 mill reduction in property taxes on your primary residence, and any contiguous vacant land. Principal Residence Exemptions that are in effect January 1 each year stay in effect for the calendar year. The May 1 filing deadline for Principal Residence Exemptions applies to new applications-only. You do not need to apply each year.
  • Property Record Card: Contains owner name and address, legal description, sales history, assessment history, picture of home, building sketch with square footage and other value-enhancing amenities. To view a copy of your Property Record, please call the Assessing Office Monday through Friday from 8 a.m. until 5 p.m. (616) 676-9191, ext. 26, or email your inquiries.

Field Review Notice

The Assessor is required to appraise, for tax purposes, all real and personal property within the Township. Michigan Statute requires that all property be evaluated annually based on current market conditions. This requires an inspection of each property in the Township.

This includes measuring all buildings and other property improvements on the property, taking current digital photos of the property, verifying the buildings' current physical condition and review the amenities present, and interviewing the property owners to determine bedrooms, baths, and type of basement, etc.

The State of Michigan has recommended that 20% of properties in a governmental unit be visited each year to review assessment record accuracy and to ensure that properties are being appraised and assessed at 50% of the market value. In efforts to continually improve our excellent standards, the Assessor’s office strives to enhance the annual review process and better meet or exceed the State of Michigan’s expectations. The goal is that the Assessing office will review at least 20% of the Township each year, then every single property is visited at least once every five years.

If one of the inspectors from the Township arrives wearing a Township issued I.D. badge and carrying a clipboard and digital camera and knocks on your door requesting to review your property, please welcome them. Accurate assessments benefit everyone in the community.
