What does the principle of contribution state regarding property improvements?

The principle of contribution asserts that the value of a property is determined by the contribution of its individual improvements to the overall value of the property. This principle highlights that not all improvements add equal value; rather, it is the enhancement they provide to the total property value that matters. For instance, if a homeowner installs a swimming pool, the additional value it brings to the property is assessed relative to the cost of installation and how much it enhances the property's appeal or function compared to similar properties without such an improvement.

Understanding this principle is crucial in real estate, as it informs decisions on whether to invest in certain upgrades or improvements based on their potential return on investment. It emphasizes a measured approach to property enhancements, focusing on their actual contribution rather than assuming that all improvements will automatically increase property value.
