Shell Condition (Cold Dark Shell / Warm Vanilla Shell)

Also known as: cold dark shell, warm vanilla shell, base building condition

The base building condition in which space is delivered to a tenant before build-out, ranging from a 'cold dark shell' with no HVAC, electrical, or finished flooring or ceiling, to a 'warm vanilla shell' with basic mechanical systems, lighting, and finished but unimproved interior surfaces.

Delivery condition directly determines the scope, and therefore the cost and risk allocation, of tenant's work versus landlord's work, making it a central negotiating point in the work letter. A warmer shell shifts more construction scope and cost onto the landlord, which is often reflected in a lower TI allowance or higher rent, while a colder shell shifts more risk and up-front capital burden onto the tenant. Lease exhibits should define shell condition with precision — for example, specifying that utilities are stubbed to the space and the premises are delivered broom-clean and code-compliant — since vague shell-condition language is a recurring source of delivery disputes; second-generation industrial and retail space is more often delivered warm or vanilla, while ground-up office and new retail pads are more often delivered cold and dark.
