Calderwick Tower: every component and its recovery period

The city owns both streets and public sidewalks. Only the private court is a site improvement in the owner allocation. Tenant desks are context. The tables below list every component this walkthrough builds, the recovery period it is assigned in this illustration, and its illustrative allocation.

Illustrative assumptions, not a valuation or tax conclusion. A real study's allocation comes from the specific property's own records.
