An Economic Condition Factor (ECF) adjusts the assessor’s use of the state mandated
cost manual to the local market. The State Tax Commission Assessor’s Manual
provides costs in which property characteristics are costed out. County multipliers are
provided by the State Tax Commission and adjusted annually to reflect change in the
market of construction costs found in this Manual bringing the costs to the County level.
ECF’s are then analyzed annually and adjusted by the assessor to further improve
these costs to our local market.
