Investor WorkspaceA little clarity for your next decision.
By Jerry Baker
Opportunity Zone rules bar certain listed activities from qualifying as a Qualified Opportunity Zone Business, including golf courses, country clubs, and some alcohol, gambling, and personal-service businesses. The rules also reach certain landlords, but allow narrowly defined small uses. The restriction applies differently to a lower-tier business and a fund that directly owns and operates property, so the ownership structure matters.
“Sin business” is a common label for a specific tax-law list. It is not a general test of whether a business is good, bad, popular, or useful to a neighborhood. The Opportunity Zone statute refers to a list in Section 144(c)(6)(B), and the regulations explain how that list applies. [1] [2]
The exact activity matters more than the name on the sign. A property called a wellness center may contain several types of businesses. A hotel may have a small spa. A retail center may lease space to a store selling alcohol for customers to take home. Those facts need review before anyone says the project qualifies.
This guide describes the rules checked on October 6, 2026. It focuses on this narrow business restriction. It does not decide whether a particular project is legal under local law, properly licensed, a sound investment, or eligible under every other Opportunity Zone rule.
The current regulation lists the following trades or businesses as ineligible to be a Qualified Opportunity Zone Business, subject to its small-use rules. It also addresses businesses leasing more than a de minimis amount of property to them. [1]
Words such as “principal business” and “off premises” are part of the alcohol rule. Do not replace them with a broader claim that every business serving alcohol is barred. At the same time, do not assume a mixed-product store passes just because it also sells snacks or other goods. Its actual business needs to be examined.
The rule’s list also does not cover every legal or investment risk. An activity that is not on this list still has to meet all other applicable requirements. Absence from the list is not a federal permit, a state license, or an investment recommendation.
A Qualified Opportunity Fund, or QOF, is the investment vehicle. It may own qualifying property directly. It may instead own qualifying stock or a partnership interest in a separate Qualified Opportunity Zone Business, often shortened to QOZB. The fund and the business have different tests. [1]
The QOF generally faces a 90% qualifying-asset standard. A lower-tier QOZB has a 70% tangible-property standard and other requirements, including the listed-business restriction. This is why an adviser needs the entity chart, not just the property address.
For example, “Opportunity Fund LLC” might hold an interest in “Main Street Property LLC,” which owns a building. If the second entity is treated as a separate partnership for federal tax purposes and must qualify as a QOZB, its business and tenant uses need review under the QOZB rules. If an LLC is disregarded for federal tax purposes, the analysis may instead occur at its tax owner. The label LLC alone does not resolve the layer being tested. [7]
The regulation includes a direct-ownership golf-course example. In it, a QOF owns and operates a commercial golf course, and the property meets all the stated requirements for qualifying business property. The example says that the listed-business prohibition does not apply at the QOF level and that the direct operation does not disqualify that fund on those facts. [1]
That is a real distinction in the rule. It means “no Opportunity Zone fund can ever own a golf course” is too broad. It does not mean any structure with a QOF name can ignore the rest of the law.
The direct fund still has to satisfy its own requirements. Those include the fund’s asset standard and the rules for qualifying owned or leased property. A lower-tier business’s working-capital protections should not be assumed to apply to cash sitting directly in the QOF. The legal and tax structure must fit the entire plan. [1] [3]
Do not move an activity between entities based only on this example. A transfer can create other tax, debt, title, contractual, or reporting issues. The example answers a narrow restriction question; it is not a do-it-yourself restructuring guide.
A lower-tier QOZB cannot avoid the restriction simply by leasing substantial property to someone else who runs a listed business. The regulation expressly reaches landlords leasing more than a de minimis amount to those activities. It includes an example where a QOZB leases a golf course to a third-party operator and fails to qualify. [1]
That matters for retail centers, mixed-use buildings, hotels, and other properties with changing uses. A landlord may have no role in selling alcohol, giving massages, or taking bets, yet the tenant’s use can affect the landlord’s QOZB status.
Review the full lease and actual use. A lease might allow a broad range of activities even if the tenant’s current business is narrow. A later assignment, expansion, or change in use may alter the facts. A rent roll that lists only the tenant’s legal name will not always answer the tax question.
Lease controls can help a manager monitor uses, but they are not a substitute for qualification. A promise that a tenant will follow the rules needs a way to detect a change and respond. The available remedies also depend on the lease and applicable law.
The regulation defines a de minimis amount of real property as less than 5% of net rentable square feet. For other tangible property, it uses less than 5% of value. It also permits less than 5% of a QOZB’s gross income to be attributable to the listed types of business. These are specific measures, not a broad “small enough” judgment. [1]
Keep the measures separate. Rent dollars are not square feet. Gross income is not net profit. Equipment value is not the number of rooms. A favorable answer under one measure does not prove that another required measure is satisfied.
The regulation’s hotel-spa example satisfies all three stated measures: the spa accounts for less than 5% of gross income, less than 5% of net rentable square feet, and less than 5% of other tangible-property value. On those facts, the spa does not prevent the hotel from qualifying as a QOZB. [1]
Use the measures that apply to the actual activity and structure. An adviser should determine whether the issue is direct operation, leasing, or both, and how to measure the relevant property and income. The hotel example is useful guidance, not a license to skip a test that is inconvenient.
Assume a fictional lower-tier property business has 100,000 net rentable square feet. A proposed tenant would use 4,000 square feet for a listed business. That use represents 4% of the space. If the correct measurement and all relevant facts support those figures, it is below the real-property threshold.
Now assume the tenant expands to 5,000 square feet. The fraction becomes 5%, which is not less than 5%. The rule does not say “round it down because it is close.” Nor does it say that a large amount of rent from other tenants can cure a square-footage failure. [1]
The denominator needs care too. The rule uses net rentable square feet, not the entire site acreage or every square foot mentioned in a development brochure. Get the measurement basis from the property records and the tax analysis. Do not add unrelated land or parking area just to make the ratio smaller.
If more than one listed use is present, do not casually treat each as having its own separate allowance. Identify the full amount attributable to the restricted activities and have counsel apply the rule. A series of small leases can present a different issue from one isolated tenant.
Consider another hypothetical. A hotel has $8 million of total gross income. Its listed spa activity produces $240,000, or 3%. The spa uses 3% of net rentable space and 4% of the relevant other tangible-property value. Assume the measurements are correct and the rest of the hotel’s facts match the rule. Each stated measure is below 5%.
Next year, the hotel’s room revenue falls while spa receipts stay at $240,000. Total gross income falls to $4 million. The spa now produces 6% of the total. Its rooms did not get larger, but the income fraction changed.
That is why a one-time floor-plan review is not enough for a business relying on the exception. The manager needs the right operating data over time. A tax adviser must determine the effect of a change under the full rules; the illustration does not assume that every brief fluctuation has the same consequence. [1]
The example also shows why net profit is the wrong shortcut. A spa could lose money after expenses while still producing a meaningful share of gross income. The test is not based on whether the restricted activity is profitable.
The incorporated list refers to a store whose principal business is selling alcoholic beverages for consumption off premises. A store focused on take-home liquor presents the stated issue directly. A restaurant that serves beverages with meals presents a different fact pattern. [1] [2]
Do not invent a universal sales percentage for the phrase “principal business” based on this article. The cited provision uses that legal standard; it does not give every mixed-use store a simple safe percentage in these lines. Counsel should assess the facts and any further applicable authority.
For a landlord, the due diligence file can include the tenant’s permitted use, licenses, operating description, and relevant sales information where available. A business name such as “market” or “café” is not conclusive. Nor is a tenant’s statement that it is “not a liquor store” enough by itself.
The purpose of this review is to classify the activity correctly. It is not to turn every restaurant lease into a prohibited use or to give every grocery tenant a free pass. Both shortcuts miss the wording of the rule.
The working-capital rules can help a qualifying business hold and spend cash under a written plan. They also provide certain related protections during startup. But the regulation expressly describes those related safe harbors as applying to requirements other than the sin-business prohibition. [1]
That distinction matters when a development is still on paper. A business cannot rely on its cash-spending plan as a reason to ignore a prohibited planned activity. The intended use should be reviewed alongside the budget and schedule, before leases and construction plans become difficult to change.
A project can meet a spending deadline and still have the wrong use. It can also have an acceptable use while failing a property or income test. The compliance file should address each requirement separately rather than give the whole project one green checkmark.
Qualifying property has its own requirements. Owned property can raise questions about acquisition, related sellers, original use, substantial improvement, and where it is used. Leased property follows distinct rules. The business may also need to meet the income, intangible-property, and financial-property requirements. [1] [3]
For example, an ordinary office business is not on the restricted list. That fact does not prove that its building purchase meets the original-use or improvement test. It also does not prove that the QOF acquired its business interest in the required manner. The use screen is one piece of a larger analysis.
The 2025 law changes several OZ rules and effective dates, including rules affecting new investment cohorts and rural property. Those changes should be checked for the actual investment. They should not be treated as a general repeal of the existing listed-business review. [5]
A property can look compliant when purchased and face new questions later. A tenant might expand a listed activity. A hotel might add a spa. A business might change its product mix. Monitoring should therefore continue after the first investment and after the first tax return.
When a change is found, identify the affected entity, the date, and the relevant measure. Then assess the effect on the QOZB and the QOF. The regulations have a limited cure rule for certain business failures, with conditions, timing requirements, and a one-correction limit. It is not a standing six-month permission to operate any prohibited business. [1]
Do not assume paying an asset-test penalty fixes every eligibility issue. The fund’s penalty rules and the anti-abuse rules have different roles. If a significant purpose of a transaction is to achieve a tax result that conflicts with the program’s purposes, the regulations allow it to be recast. [4]
Ask the sponsor to show which entity owns the real estate and which entity runs each business. Ask which entities are treated as separate taxpayers. Then ask whether any current or planned use falls within the listed activities, including uses by tenants and subtenants.
If the plan relies on a small-use exception, request the actual calculation and its source data. Which square feet, income, and property values were used? What period does the information cover? Who updates it? How much room is there before the threshold is reached? These are practical questions, not demands for a guaranteed tax result.
Read the risk disclosures as well. A private fund’s securities status and its tax status are different matters. Private placements can involve limited disclosure, illiquidity, and substantial risk. An adviser’s OZ analysis does not remove those investment concerns. [6]
Finally, ask what happens if the facts change. A useful answer identifies monitoring, decision authority, notice to investors, and access to tax advice. “We checked it once” is not a full operating plan for a long holding period.
A short worksheet can make this review easier to follow. For each activity, list the operator, the tax owner, the property used, and the reason it may fall within the restricted list. Then list the source of the facts: a lease, floor plan, sales report, equipment schedule, or written description of services.
Keep a separate column for the legal conclusion. A property manager can confirm that a tenant uses 3,600 square feet. The tax adviser can determine how that fact fits the rule. Keeping those steps apart makes it easier to update the analysis when one fact changes.
For instance, 3,600 square feet out of 90,000 net rentable square feet equals 4%. If the correct total is only 72,000, the same use reaches 5%. The numerator did not change. A better measurement changed the answer. This is a hypothetical area calculation, not an opinion on a particular lease.
Document uncertainty too. If gross-income data is not yet available, say that the income test has not been confirmed. Do not turn “we have not seen a problem” into “the test passed.” An investor can then decide whether the missing information must be resolved before funding, whether the documents address the risk, and what further professional review is needed.
No. The listed alcohol category is a store whose principal business is selling alcoholic beverages for consumption off premises. Other facts require their own review. The wording should not be shortened to a ban on every restaurant or hotel that serves drinks. [2]
The landlord rule and the de minimis measures must be checked. Leasing more than the permitted small amount to a listed business can prevent QOZB status. A small lease is not automatically safe without the relevant calculations and facts. [1]
No. The regulation says less than 5% for the stated measures. Exactly 5% does not meet that wording. Use the correct denominator and do not rely on rounding to create a margin. [1]
No. The regulation’s hotel example allows a spa where its gross income, net rentable space, and other tangible-property value are each below the stated 5% measures. The example’s facts matter; a larger spa may present a different result. [1]
The regulation expressly provides an example where it can, because this prohibition does not apply at the QOF level. All other fund and property requirements still apply. That example does not approve every golf-course investment or structure. [1]
No. The related startup safe harbors do not suspend the sin-business prohibition. Planned uses need review even while cash is being held and spent under an otherwise valid plan. [1]
Not necessarily. This is a tax classification screen. The project still needs legal, financial, operational, and securities review, along with the rest of the OZ requirements. Tax eligibility does not assure profits or protect principal. [3] [6]
Do not assume so. The effect of a failure, any available cure, and the fund’s asset-test penalty require separate analysis. Paying a charge is not blanket permission to disregard qualification or anti-abuse rules. [1] [4]
