What types of building improvements are eligible for the bonus depreciation allowance?
The 2002 Act does not define what types of building improvements are eligible to be treated as qualified leasehold improvement property. Rather, it lists the types of property that cannot be so treated. Qualified leasehold improvement property does not include any improvement for which the expense is attributable to: enlargement of the building, any elevator(s) or escalator(s), any structural component benefiting a common area, and the internal structural framework of the building.
