Michael Galligan, County Equalization Director
Josh Morgan, Assessing Division Supervisor

The Assessor’s Office is responsible for establishing the true cash (fair market) value of real and personal property. The City partners with the Ottawa County Equalization Department to provide these services for the City. County Assessor Josh Morgan is in attendance at Grand Haven City Hall once a week, on Wednesdays from 8:00 a.m. to 12:00 p.m.

The office sets values on over 6,000 properties in the City. This is done with sales ratio studies in order to maintain assessed values at 50 percent.

The office uses the fair market value to derive a property’s:

  • Assessed value (half the true cash value)
  • State equalized value (S.E.V.), which is usually, but not always, the same as the assessed value
  • Taxable value, along with the millage rate, is used to determine amount of property tax

The office takes various factors into account when establishing property value, including:

  • Description of the property and its improvements
  • Lot dimensions
  • Age of home and/or other buildings
  • Land value
  • Building square footage
  • Value-enhancing amenities

Public Information

Access to the following information is provided through the Assessor’s office:

  • Name of registered owner of property at a particular address. May be an individual or a business.
  • A property’s tax roll description, assessed value, and S.E.V.
  • Maps of City parcels. The maps give the location of property designated by specific parcel numbers and a diagram of property configuration.

Special Assessments

Special assessments questions should be direct to the Treasurer’s office. Their amount is determined in the Treasurer’s office, and records of whether assessments are due or delinquent are kept there. The Assessor’s office can give some information as to the initial figures on which the assessment was based (square footage, etc.)

Tax Abatements

The Assessor’s office determines assessed value, S.E.V., and taxable value of property for tax abatements.
