The landscape of tax-efficient investing in distressed communities is layered and technical, but it rewards those who map the rules correctly. This article distills several complementary tools — Section 280B demolition planning, bonus depreciation, cost segregation, and the tangible property / partial disposal rules — into practical pathways investors can use inside Opportunity Zones. Throughout, we emphasize how these strategies affect basis, depreciation recapture, and treatment of original use for qualifying assets.
Read on for clear explanations and concrete examples that show why a demolition or a carefully scoped cost segregation study can change whether an asset qualifies from day one, how much can be expensed in year one, and what disappears after a 10-year holding period. The objective is not theory but actionable clarity that helps you plan acquisitions and redevelopments in qualified tracts.

Turning buildings into original use with Section 280B
At the heart of several Opportunity Zone plays is Internal Revenue Code Section 280B, which governs how a demolished building’s remaining basis is treated. Simply put, if you remove a structure, the leftover basis in that structure is typically capitalized into the land rather than recognized as a loss. Because land is treated as having original use in an Opportunity Zone, this shift can allow newly built assets to qualify immediately without meeting the onerous 30-month substantial improvement rule.
How the 75% demolition threshold works
Tax guidance from the 1990s draws a bright line: if you maintain at least 75% of the original exterior walls and structural components, the asset is considered an existing building. If you preserve less than that, the transaction can be treated as a deemed demolition. That threshold is the lever many investors use to move a building’s basis into the land bucket and thereby treat subsequent construction as original use.
A simple numeric example
Imagine a $3 million purchase where $1 million is allocated to the building and $2 million to the land. Execute a demolition that qualifies under Section 280B and the $1 million building basis becomes part of the $3 million land basis. Because land can be treated as original use in the zone, the redeveloped property can meet Opportunity Zone acquisition rules from day one — a structural shift with meaningful tax consequences.
Accelerated deductions: bonus depreciation and cost segregation
To capture near-term tax benefits, many practitioners pair demolition strategies with a cost segregation study. For buildings with total costs above about $500,000, a study — typically costing between $8,000 and $12,000 — isolates personal property and land-improvement components that depreciate over 5, 7, or 15 years instead of 27.5 or 39 years. That reclassification increases current-year deductions and improves cash flow.
Additionally, the so-called one big beautiful bill (OB3) restored 100% bonus depreciation retroactively for assets placed in service on or after January 19th or 20th of 2026. Practically, this can allow roughly 15–30% of a building’s cost to be expensed in year one when combined with a segregation study. Importantly for Opportunity Zone investors, depreciation recapture that would normally hit at disposition can be eliminated if the asset is held for the full 10-year qualified period: after that point a basis-step-up tied to fair market value can remove the usual 1245 and 1250 recapture exposures.
Partial disposals, operating businesses, and the road ahead
The tangible property repair regulations introduced methods for handling replaced components — known as partial disposals — which let owners remove the remaining basis of replaced items without going through costly component-specific accounting, sometimes using producer price index adjustments. In non-OZ contexts that eliminates depreciation recapture on disposed pieces; within Opportunity Zones, partial disposals remain useful but must be balanced against Section 280B interactions so you do not accidentally trigger demolition rules.
Despite these tools, operating businesses have attracted only a small fraction of OZ capital. A recent survey cited roughly 3% of raised equity going to active businesses rather than real estate. Two reasons dominate: the gross income test (requiring 50% of receipts to be generated inside the zone) is operationally burdensome, and investors often prefer alternatives like Section 1202 that can deliver a five-year, tax-favored exit with less compliance friction. Still, businesses can scale beyond real estate’s typical returns, and the OZ program’s original aim was to drive entrepreneurial growth in underserved areas.
Finally, as OZ 2.0 designations approach, pay attention to state selection processes. Nominations are expected to begin on July 1, with the new map scheduled to go live on January 1, 2027. States that coordinate urban and rural voices and prioritize economic activity will likely create the most attractive markets for future Opportunity Zone investment. For investors, the message is clear: combine demolition planning, targeted cost segregation, and thoughtful use of bonus depreciation to maximize basis shifts and tax efficiency while watching how new zone geography reshapes opportunity.
