What is the term for an improvement that a tenant attaches to real estate, specific to their business operation?

The term for an improvement that a tenant attaches to real estate, specific to their business operation, is a trade fixture. Trade fixtures are items that are installed by the tenant to conduct their business and are considered personal property, even though they are attached to the property. This distinction is crucial because tenants have the right to remove these fixtures at the end of their tenancy, as they are intended for the tenant's use and are vital to the operation of their business.

In the context of real estate law, understanding what constitutes a trade fixture versus other types of fixtures can significantly impact both the tenant's rights and the landlord's expectations. This typically applies in commercial leases where tenants customize a space to fit their operational needs.

Other terms, such as lease, holdover tenant, and rental agreement, refer to broader contractual or situational aspects of property rental and do not specifically denote improvements attached by a tenant for their business purposes. Therefore, the distinct definition of a trade fixture makes it the correct answer in this context.
