New RPIE-2025 Question: Is Your Property Subject to RPTL § 581-a?

The NYC Department of Finance has added a new question to the RPIE-2025 form. In Section E, DOF now asks:

“Is your property subject to valuation under New York State Real Property Tax Law (RPTL) Section 581-a?”

The form explains that RPTL § 581-a applies to a residential property that is subject to an agreement with a government entity restricting occupancy of at least 20% of the residential units to tenants who meet income requirements. The answer choice is YES or NO. DOF’s RPIE-2025 filing deadline is June 1, 2026, and DOF uses RPIE income and expense information to value income-producing properties for the following tax year, 2027/28.

This is a small question with potentially significant valuation consequences.

What RPTL § 581-a Does

RPTL § 581-a is not new. It was enacted in 2005. What is new is that NYC DOF has now added a direct RPIE question that allows an owner to identify the property as potentially subject to § 581-a.

The statute applies to real property used for residential rental purposes where at least 20% of the residential units are subject to an agreement with a municipality, the State, the federal government, or an instrumentality of government, and that agreement restricts occupancy of those units to tenants who qualify under an income test. When § 581-a applies, the assessed valuation must be determined using the income approach as applied to the actual net operating income, after deducting required reserves. The statute also says the valuation shall not include federal, state, or municipal income tax credits, subsidized mortgage financing, or project grants used to offset development costs to provide lower initial rents.

In other words, if the property is required by a government affordability agreement to rent at least 20% of its units to income-qualified tenants, the law recognizes that the property’s income and value are restricted. The assessment should reflect the actual restricted economics, not a hypothetical market-rent building.

How to Answer the New RPIE Question

For most owners, the answer can be approached with four basic questions:

1. Is the property a residential rental property?
2. Are at least 20% of the residential units covered by an affordability agreement, restrictive declaration, regulatory agreement, covenant, or similar document?
3. Is that agreement with, or required by, a government entity or instrumentality?
4. Does the agreement restrict occupancy based on tenant income, such as AMI limits or another income test?

If the answer to all four questions is yes, the RPIE answer is generally likely to be YES.

If the property merely has rent-stabilized units, but no income-tested occupancy restriction, the answer is generally likely to be NO.

The key point is that § 581-a is not triggered by ordinary rent regulation alone. It requires an income-tested occupancy restriction imposed by a qualifying government agreement.

Where to Find the Agreement

Owners should look for the document that created the affordability restriction. It may be called a:

• restrictive declaration;
• regulatory agreement;
• affordability covenant;
• HPD or HDC regulatory agreement;
• LIHTC extended use agreement;
• bond regulatory agreement;
• written government agreement;
• Land Disposition Agreement;
• Enforcement Mortgage;
• HPD certification package or related restrictive document.

In New York City, recorded restrictive agreements can generally be found on ACRIS. ACRIS allows users to search and view document images for recorded real property documents in Manhattan, Queens, Bronx, and Brooklyn. The City Register maintains property transfer and related public records for those four boroughs, while Staten Island records are maintained by the Richmond County Clerk.

Owners should also check title reports, closing binders, lender files, HPD/HDC files, tax exemption applications, and property management compliance files. Not all documents that create affordability restrictions are recorded on ACRIS.  For example HPD’s practice in years past was to execute but not require recording of certain documents (typically prior to 2015).

Examples of Properties That May Answer “YES”

A residential rental property may generally answer YES if it has at least 20% income-restricted residential units under a recorded or binding government affordability agreement.

Examples may include:

Old 421-a 20 or 25-year projects. Many of these projects, but not all, have affordability restrictions that can satisfy the income-test requirement.

421-a(16) rental projects with affordable housing options. Under 421-a(16), the affordable unit categories expressly restrict initial and subsequent rentals after vacancy to households whose income does not exceed specified AMI percentages. HPD’s 421-a materials also reference restrictive declaration requirements and templates for 421-a(16) rental projects.

421-a(17) extended-benefit projects. The 421-a(17) extension for certain old 20- or 25-year 421-a rental projects generally requires additional affordability commitments. HPD describes the extension as requiring, among other things, at least 20% of dwelling units restricted to households at or below an average of 80% of AMI and at least an additional 5% of units restricted to households at or below 130% of AMI, with restrictive declaration materials.

485-x Options A and B. HPD’s 485-x materials describe Option A and Option B as requiring specified percentages of Affordable Housing Units with AMI-based affordability levels, and also state that projects must submit restrictive declarations. By contrast, Option C is described as a small rental-project option based on rent stabilization of at least half the units, which is different from an income-tested occupancy restriction.

467-m projects. The 467-m program includes affordability requirements for eligible conversions, including AMI-based affordable housing unit restrictions and long-term affordability compliance. HPD’s materials also refer to required legal instruments and restrictive declarations.

LIHTC, bond-financed, HDC, HPD, Article XI, or other government-regulated affordable housing projects. These often have recorded regulatory agreements or covenants requiring income-qualified occupancy for a percentage of units.

The label of the program is helpful, but it is not enough by itself. The better question is: what does the actual recorded agreement require?

Examples of Properties That May Answer “NO”

A property generally may answer NO if there is no agreement restricting occupancy of at least 20% of residential units to tenants who qualify under an income test.

Examples may include:

Rent stabilization alone. A rent-stabilized unit is rent-regulated, but it is not necessarily restricted to a tenant who satisfies an income test. Even if the unit became rent stabilized because of 421-a, that fact alone does not mean the unit is income-restricted for § 581-a purposes.

Old 421-a 15-year projects. These projects may have rent-stabilization requirements without an income-tested occupancy covenant.

485-x Option C. Option C is generally structured around rent stabilization rather than a 20% income-tested affordable housing set-aside.

Buildings with more than 20% rent-stabilized units but no affordability agreement. The percentage of regulated units is not the test. The test is whether at least 20% of the residential units are subject to a qualifying government agreement restricting occupancy based on tenant income.

Common Traps

The most important trap is confusing rent regulation with income-tested occupancy restriction. They are not the same thing.

A second trap is assuming the restriction must be permanent. It does not. For RPIE purposes, the question is whether the property is subject to the qualifying restriction now. A restriction that expires in one year may still matter if it is currently in effect.

A third trap is assuming that vacant affordable units do not count. If the property has a binding agreement requiring 20% income-restricted units, the existence of temporary vacancies should not automatically change the answer. The question is whether the units are subject to the agreement.

A fourth trap is failing to review the regulatory agreement for Article XI, LIHTC, bond, HDC, HPD, or other affordable housing properties. Some agreements will satisfy § 581-a; others may not. The agreement controls.

Why DOF Is Asking About 581-a

The theory behind the new RPIE question is straightforward. If the property is subject to § 581-a, then DOF should be alerted that valuation must be based on the property’s actual net operating income, rather than a valuation approach that treats the property like an unrestricted market-rate rental.

That is exactly why § 581-a was enacted. In Warrensburg Commons LPT v. Town Assessor of the Town of Warrensburg, the Third Department explained that § 581-a was enacted to address the disadvantage faced by affordable housing owners when some communities assessed affordable housing using market rents rather than the restricted rents actually received. The court described the statute as intended to eliminate uncertainty and promote uniform treatment.

The bill jacket tells the same story. The Legislature was concerned that affordable rental properties could be assessed as if they charged market rents, even though government restrictions limited the rents and income the properties could actually generate. The purpose was to provide a more realistic and uniform valuation method for affordable rental housing.

The new RPIE question gives DOF a direct way to identify these properties.

How 581-a can help a Tax Certiorari Protest

A YES answer may matter because § 581-a can change both parts of the valuation equation: the NOI being capitalized and the capitalization rate used to convert that NOI into value.

For a qualifying property, § 581-a requires valuation by the income capitalization approach, applied to the property’s actual net operating income. That is different from valuing the property by comparison to unrestricted market-rate apartment buildings, or by relying on market rents the property is legally unable to charge. It also means that a sales-comparison approach should not control the valuation of a § 581-a property, even if the property recently sold. A sale price may reflect more than the taxable real estate. It may include, or be influenced by, tax credits, subsidized financing, project grants, regulatory benefits, assumed financing, investor structure, or other elements of the affordable housing transaction that § 581-a says should not be included in the assessment valuation.

That is one of the core points of the statute. The property should be valued based on the restricted real estate income, not as if it were an unrestricted market-rate rental and not as if the assessor could capture the value of the affordable housing financing package. The legislative history describes this exact problem: affordable housing properties were sometimes assessed using market-rent assumptions even though the properties were legally restricted to lower rents, and § 581-a was intended to require a more realistic valuation based on restricted income.

For protest purposes, this can be very important. If DOF or the Tax Commission is using comparable properties, market rents, or a model that produces income higher than the property’s actual restricted NOI, the owner may be able to argue that the valuation does not comply with § 581-a. The statute directs the assessor to use the income approach as applied to actual NOI, after the required deductions, rather than a valuation method that effectively assumes unrestricted economics.

The capitalization rate is the second major issue. In the income approach, value is generally calculated by dividing NOI by a capitalization rate. A lower NOI produces a lower value. A higher capitalization rate also produces a lower value. For example, a property with $1,000,000 of post-tax NOI is worth $20,000,000 at a 5% cap rate, but only $12,500,000 at an 8% cap rate. Small cap-rate differences can have large valuation consequences.

The taxpayer prevailed on this issue in Cohoes Falls Limited Partnership v. Board of Assessment Review. There, the taxing jurisdiction’s appraiser used a 4% capitalization rate and justified that low rate in part by reference to the property’s LIHTC structure, low-risk investment profile, stable income stream, and subsidized financing. The Third Department held that this violated § 581-a because the statute prohibits consideration of income tax credits and subsidized financing to enhance the value of the property. The court found the taxing jurisdiction’s appraisal “foundationally flawed” and reduced the assessments.

That point may be especially relevant in NYC valuation disputes. A regulatory agreement may provide economic stability, but § 581-a does not allow the assessor to use the government-created affordability structure, tax credits, subsidized debt, or project grants as a reason to enhance taxable value. In other words, the assessor should not say, in substance: “This property deserves a lower cap rate because the affordable housing program makes the investment safer,” if the reason for that stability is bound up with the very regulatory and subsidy structure that § 581-a excludes from valuation.

The better argument for the taxpayer is that the assessment should reflect the property’s actual restricted NOI, capitalized at a rate that does not improperly capture the value of tax credits, subsidized financing, project grants, or the subsidy-driven investment structure. If the actual NOI is lower than DOF’s modeled income, and if the proper cap rate is higher than the rate implied by DOF’s valuation, the result should be a lower taxable value.

That is why the new RPIE question matters. A property that properly answers YES may have an additional valuation argument in a Tax Commission hearing or tax certiorari proceeding if the assessment does not reflect § 581-a’s required income-capitalization methodology, the property’s actual restricted NOI, and the statutory exclusion of tax credits, subsidized financing, and project grants.

Next Steps

Owners completing RPIE-2025 should not wait until the filing deadline to investigate this question.

First, identify whether the property has any affordability, exemption, regulatory, LIHTC, bond, HPD, HDC, or similar program history.

Second, locate the restrictive declaration, regulatory agreement, or covenant. In many cases, the recorded agreement can be found on ACRIS.

Third, confirm whether at least 20% of the residential units are subject to an income-tested occupancy restriction.

Fourth, answer the RPIE question consistently with the agreement and keep a copy of the supporting document.

Finally, do not assume that rent stabilization alone is enough. The agreement must restrict occupancy by tenant income.
