Michigan law requires the Assessor to annually value all taxable property at 50% of market value.  Taxable properties include homes, factories, commercial properties, farms and vacant land.  It also includes personal property for commercial and industrial businesses.

The Assessing department also keeps records on ownership, addresses, homestead exemptions, sales, and land and building details for approximately 2,000 properties located within the City.

Transfers of Ownership
Any time a transfer of ownership takes place on a property, the buyer or grantee (person receiving the property) is required by Michigan State Law to file a Property Transfer Affidavit with our Assessor's Office within 45 days of the transfer.  Please send or drop off this form to Assessor, 300 N Mill Street, St. Louis, MI 48880.

Property Site Visits  (April 15-December 31)
The Assessor's Office makes several property visits throughout the year.  Most notably, the Assessor and/or staff visits all of the sites that have been issued a building permit throughout the year by the City's Building Inspector.  In addition, property-by-property reviews are conducted of the entire City, with field staff visiting roughly 20% of the parcels in the City each year.  While completing property site visits, Field Staff will have business cards and official city identification.    Frequently Asked Questions about Property Inspections.
