What are alterations or additions made to a building at the expense of an insured who does not own the building called?

The term for alterations or additions made to a building at the expense of an insured who does not own the building is known as improvements and betterments. This term is commonly used in the context of commercial property insurance, where tenants or insured parties invest in enhancing or making modifications to the space they occupy.

Improvements and betterments refer specifically to modifications that increase the value of a property or adapt it to meet the needs of the tenant. These might include new fixtures, built-in furniture, or upgraded systems. The important aspect is that these enhancements were made by the non-owner, and thus they may not be covered under a standard property policy held by the owner.

Understanding this concept is crucial for licensed agents, as it affects the determination of coverage in specific scenarios where tenants may want to ensure that their investments in the property are protected.
