Building obsolescence may be brought about by a change in all of the following EXCEPT which of the following?

Building obsolescence refers to the loss of value of a property due to factors that make it less desirable or functional over time. This can occur due to changes in the market, regulations, or advancements that render a structure inadequate for current needs or standards.

When considering wear and tear, it is important to understand that this is a natural process associated with aging and the use of a building. Unlike the other factors listed, which are external changes in the environment or industry standards, wear and tear is an intrinsic aspect of the building's physical condition. It typically does not reflect a shift in desirability caused by market trends, updates in building standards, or technological changes. Instead, wear and tear simply indicates that a building is experiencing deterioration due to time and usage, without suggesting that it has become functionally obsolete due to external factors.

In contrast, market trends reflect changing buyer preferences, building codes may require updates that can render older buildings non-compliant, and technological advancements can introduce new features or efficiencies that older buildings lack. These external changes can directly result in obsolescence as they impact how the building is utilized and perceived in the marketplace.
