Assessing Department
The Assessing Department is responsible for the preparation of the annual Assessment Roll which is completed in accordance with the General Property Tax Act (GPTA). The Assessing Department follows the GPTA and State Tax Commission (STC) guidelines in order to determine taxable status, true cash value, assessed value, and taxable value for all real and personal property within the City of Warren.
The Assessing Department does not create value. Rather, value is created by economic forces in the market of buyers and sellers. The Assessor has the responsibility to study the transactions of the market and to appraise all property in accordance with market trends.
The Assessing Department also serves as the primary source of property information in the City by maintaining the most current data for more than 59,077 parcels, consisting of approximately 54,620 real and 4,457 personal property parcels. The Assessing Department also keeps track of ownership changes, maintains maps of parcel boundaries, maintains legal descriptions for all land, and prepares sketches of all buildings summarizing their characteristics.
Our Staff
Assessing personnel are statutorily required to be certified by the State Tax Commission at varying levels of expertise for each of the different duties required within the Department. All certified personnel must meet annual continuing education requirements.
Current Year Land Analysis and Economic Condition Factor
The Assessing Department uses BS & A software to maintain a database of property information. The integrity of information in this database is vital to supporting departments of the City, including Treasury, Planning, Building, Water, Rental, and Property Maintenance.
Access to this database is available to the public free of charge.
