What are the relevant code (IRC) sections which allow for the depreciation?
Section 263A: This is the Internal Revenue Code section mandating that various components of the building and other direct or indirect costs be included in the total cost of a building. Cost segregation studies can better help determine what goes into the cost basis of a building for future accelerated depreciation. This is especially helpful for new purchases of buildings. Without these costs, a property owner might not understand the total depreciable value of the building. From the example above, the electrical wiring would be an example of a 263A cost. Direct costs are materials, labor, and contractor expenses to make various items (water and sewer lines, electrical systems, paving and curbs, fencing and security features, site signage and lighting, and outdoor recreational amenities, esp as part of a development or RV park). Indirect costs are things like design fees, engineering costs, construction supervision, purchasing, and certain overhead expenses. But a word of caution: certain expenses do not qualify (marketing, selling, unrelated admin costs) and should be expensed separately and not part of the building purchase.
