About

The City Assessor’s Office exists by city ordinance and is governed by the City Conference Board. The Conference Board has three voting units and the Mayor is the chairperson.

• Mason City City Council
• Cerro Gordo County Board of Supervisors

The Assessor is appointed to their position by the Conference Board and is required to pass a state examination. Assessors are appointed for six-year terms and must complete a continuing education program consisting of 150 hours of formal classroom instruction (with 90 of those hours being tested courses and a passing grade of 70% or higher) to be eligible for re-appointment.

The Assessor may appoint one or more deputy assessors as deemed appropriate by the Conference Board. Deputy Assessors must also pass a state examination and must complete a continuing education program consisting of 90 hours of formal classroom instruction (with 60 hours being tested courses) in order to be eligible for re-appointment.

The main responsibility of the Assessor is to list and value all real property within their jurisdiction. This includes residential, multi-residential, commercial, industrial, and agricultural classes of property. Real property is revalued every two years, and the effective date of the assessment is January 1st of the current year.
