In the context of real estate, what is functional obsolescence?

Functional obsolescence refers to a reduction in a property's value resulting from outdated or inefficient features that do not meet the current needs or preferences of buyers or occupants. This concept encompasses aspects such as a poor layout, insufficient amenities, or design choices that are no longer appealing or practical. For instance, a home with a single bathroom may experience functional obsolescence in a market where two or more bathrooms are standard for family needs.

This is distinct from other types of obsolescence. Natural wear and tear pertains to the physical deterioration of a property over time, while a decline in value due to external factors relates more to location or market conditions, such as changes in neighborhood desirability. Legal degradation of property value typically involves zoning issues or changes in property laws that affect legality or usability but do not directly address the functional aspects of the property itself. Understanding functional obsolescence is critical for appraisers and real estate professionals as it impacts property valuation and marketability.
