According to the principle of contribution, which scenario best illustrates when an improvement does NOT add value equal to its cost?
Correct Answer
B) An ADU costing $180,000 increases a property's market value by $120,000 based on comparable sales data
The principle of contribution holds that an improvement's value is measured by what it adds to the property's market value — not by what it costs to build. When an ADU costs $180,000 to construct but comparable sales data shows it adds only $120,000 in market value, the improvement contributes less than its cost, resulting in a $60,000 value gap. This is the defining condition the principle of contribution warns against.
