What Is Diminution in Value?
When someone damages your Florida property, you are entitled to damages. But how do you measure the loss? There are two primary methods:
- Cost of Repair — How much it costs to fix the damage.
- Diminution in Value — How much the property's fair market value dropped because of the damage.
Florida courts generally use the cost of repair when the damage can be fully fixed. But when repairs cannot fully restore the property, or when the cost to repair exceeds the property's value, the court uses diminution in value.
When Diminution in Value Applies
- Permanent Damage — A neighboring property's chemical spill permanently contaminates your land. Even after remediation, the stigma of contamination reduces your property's value. The diminution (the difference between the value before and after contamination) is your damages.
- Repair Cost Exceeds Value — A construction defect would cost $300,000 to repair, but the entire house is only worth $250,000. The court will not award $300,000 in repair costs; instead, it awards the diminution in value.
- Stigma Damages — Even after a property is physically repaired, the market may perceive it as less valuable because of its history (prior flood damage, prior contamination, prior structural failure). This residual loss in value is a form of diminution.
Calculating Diminution
The formula is straightforward: Diminution = Fair Market Value Before Damage − Fair Market Value After Damage. Both values are established through expert appraisals, and the competing appraisers' opinions are often the central battleground at trial.
