To substantiate that a metal steel building is not considered a structural component under IRS guidelines, you must maintain comprehensive records that clearly demonstrate the building’s function, use, and relationship to the equipment or processes it houses. The goal is to show that the building either (1) is essentially an item of machinery or equipment, or (2) houses property used as an integral part of a qualifying activity (such as manufacturing or production), and its use is so closely related to the use of such property that the structure can be expected to be replaced when the property it initially houses is replaced. This is based on the exceptions to the definition of "building" in Treas. Reg. § 1.48-1(e)(1) and related authorities.
1. Key Records to Keep:
Design and Engineering Documents:
- Architectural and engineering plans showing the building’s design, including any features specifically tailored to house, support, or interact with particular machinery or equipment.
- Documentation of any specialized construction (e.g., reinforced floors, custom openings, integrated supports) that is necessary for the operation of the equipment.
Construction and Installation Records:
- Contracts, invoices, and correspondence with contractors or suppliers that detail the purpose and specifications of the building.
- Records showing the sequence of construction and installation, especially if equipment was installed before or during the construction of the building, indicating the building was constructed around the equipment.
Operational Records:
- Maintenance logs, operating manuals, and process flow diagrams that demonstrate the building’s role in the operation of the machinery or process.
- Evidence that the building is not used for general purposes (such as office, storage, or sales space), but is integral to the operation of specific equipment.
Regulatory and Contractual Documents:
- Contracts or agreements (such as with government agencies or customers) that restrict the use of the building to a specific process or activity.
- Environmental or safety permits that require the building to be used in a particular way or to be decommissioned or demolished when the equipment is retired.
End-of-Life and Replacement Documentation:
- Records or studies showing that the building is expected to be retired, demolished, or rendered unusable when the equipment it houses is replaced or ceases operation.
- Cost analyses or feasibility studies demonstrating that adapting the building for alternative uses would be prohibitively expensive or impractical.
Photographic and Physical Evidence:
- Photographs or videos of the building during and after construction, showing the integration with the equipment.
- Evidence of physical barriers to alternative use (e.g., contamination, specialized containment, or location within a restricted area).
Industry and Site-Specific Studies:
- Industry reports or expert opinions supporting the assertion that such buildings are not reused or repurposed, and are typically demolished when the equipment is retired.
Accounting and Depreciation Records:
- Fixed asset ledgers and depreciation schedules that separately identify the building and the equipment, and reflect the intended recovery period based on the building’s expected useful life tied to the equipment.
2. Why These Records Are Important:
- The IRS and courts look at the facts and circumstances to determine whether a structure is a "building" or a "structural component" (which would be § 1250 property), or whether it is "other tangible property" or "machinery or equipment" (which could be § 1245 property).
- Key factors include whether the structure is specifically designed for the equipment, whether it can be economically used for other purposes, and whether it is expected to be replaced when the equipment is replaced.
- The burden of proof is on the taxpayer to substantiate the classification, so detailed and contemporaneous records are essential.

4. Conclusion
To substantiate that a metal steel building is not a structural component under IRS guidelines, you must keep detailed records that demonstrate the building’s specialized, integral, and non-general-purpose nature, its close relationship to the equipment or process it houses, and the expectation that it will be retired or demolished when the equipment is replaced. These records are critical to support your tax position in the event of an IRS examination or audit.
