Assessing Department

The Township Assessing Department is updating property record card information, photos, and sketches and performing onsite property inspections for the township’s commercial, industrial, and residential neighborhoods.


Our department is primarily responsible for performing and maintaining property assessments for the equitable distribution of property tax burden, per the current Michigan General Property Tax Laws.


The Assessing Department compiles the annual assessment role on which taxes will be levied, maintains property tax descriptions and maps, processes personal property statements, and conducts field audits of both existing properties and new construction located within Marquette Charter Township. The Assessing Department provides the township treasurer with taxable value on all township properties, used to produce the annual tax bills.


  • Establish legal assessment roll and annually site-visit 20% residential properties
  • Review and evaluate commercial and industrial property
  • Site visit and review all new construction
  • Continue public education in areas such as non-consideration forms, homestead applications, property transfers, and personal property tax law
  • Enhance and increase understanding of and compliance with the property tax system as established by Township ordinances and State law



Assessed Value shall not exceed 50% of the True Cash Value of the property. Assessors use mass appraisal techniques to determine the true cash of each property every year and sets the Assessed Value at 50% of the True Cash Value. True Cash Value of a property is synonymous with market value.



Capped Value is a calculation of the previous year’s Taxable Value multiplied by the Inflation Rate Multiplier and adjusted for any physical changes in the property. The inflation rate multiplier is based on a two year average of Consumer Price Index CPI.



Taxable Value is determined by the lower of the Assessed Value or the Capped Value. Properties that transferred ownership in the previous year will have the Taxable Value set to the current Assessed Value. Taxable Value is the basis of property tax in Michigan and is multiplied by the millage rate to determine the tax amount each year.



State Equalized Value (SEV) is final Assessed Value after the County and State complete their equalization processes and certify the Assessed and Taxable Values. Typically, the SEV is the same as the Assessed Value.

I have been with Marquette Charter Township since October of 1998, as the Deputy Treasurer/Administrative Assistant. In 2004, I became a Michigan Certified Assessing Officer (FKA a Level 1 Assessor) and immediately following in 2005 I became certified as a Level 2 Assessor. Our township has experienced tremendous growth both in the Residential and Commercial classes which resulted in the Township requiring a Michigan Advanced Assessing Officer (MAAO). In 2012, I completed the education requirements of the MAAO program through the State Tax Commission and was named Marquette Township’s Assessor. In September of 2017, I achieved my Michigan Master’s Assessing Officer Certification.

I have been with Marquette Charter Township since 2004. I graduated from Lake Superior State University and started out as a Firefighter/EMT. In 2005 I was hired part-time to assist with Property Maintenance (blight). I then started to assist in both the Planning/Zoning and Assessing departments in a support role. In April 2011 I was hired-full time to work in both departments in the same capacity. I became a Michigan Certified Assessing Technician in May of 2012 and a Michigan Certified Assessing Officer in January of 2017. I now work full-time in the Assessing Department.
