Tenant Improvements (TI): The process of improving or upgrading tenant spaces to meet the needs and desires of a particular tenant. This could include changing layouts, renovations, repairs, or adding amenities. In addition to making the space more desirable to potential tenants, TI also allows leases to be customized for businesses that need specific accommodations or improvements. Ultimately, tenant improvements add value to both the tenant’s individual experience as well as to the property as a whole.
