TI (Tenant Improvements) plans are construction documents prepared to modify an existing commercial space to meet the specific needs of a new or existing tenant. These plans typically show interior alterations such as new partitions, finishes, mechanical, electrical, and plumbing modifications, accessibility compliance, and life-safety requirements, while generally leaving the building’s structural shell unchanged.
