Functional Obsolescence
Definition and meaning of Functional Obsolescence in real estate.
Functional obsolescence is a reduction in a property's value or usefulness due to outmoded design, poor layout, or features that do not match modern buyer expectations.
In more detail
This condition occurs when a building's design elements are outdated or inefficient, even if the structure itself is in excellent physical shape. Examples include a home with a four-bedroom layout but only one bathroom, or an office building with inadequate electrical capacity for modern technology.
Appraisers deduct value for this type of obsolescence during the valuation process. While some functional issues can be corrected through remodeling, others are too costly or physically impossible to fix, which is known as incurable obsolescence.
