Tribeca's Pied-à-Terre Surcharge Runs on a Number Most Buyers Never See

One downtown owner rents his apartment for more than $50,000 a month. In August, The Real Deal reported that he worked out what New York City's new non-primary residence surcharge would cost him: about four months of rent. His response was to add a rider to his existing tenant's lease saying the tenant would live there full time.

The lease rider shows what this tax is really based on. Most people have heard it described as a levy on luxury second homes worth $5 million or more. In Tribeca, for its first two years, the cost depends on two other things. The first is a Department of Finance valuation, which is a different figure from the contract price. The second is whether someone can show the apartment is their primary residence on a particular date in January. The first bills are due January 1, 2027.

The figure on the bill is not the figure on the contract

The surcharge comes from Part HH of the state budget bill S.9009-C. The Legislature passed it May 27, 2026, and Governor Hochul signed it the next day. It applies to fiscal years starting July 1, 2026. The city's implementing rule took effect July 14.

For fiscal years 2026-27 and 2027-28, a condo or co-op unit is covered once its DOF market value reaches $1 million. Under Tax Law §1351, that phase-one figure is the market value DOF already assigns to the unit for property tax. For a co-op, DOF takes the building's market value and divides it according to each unit's share of the stock. According to DOF's own explanation, condos and co-ops are valued differently under state law, so a unit valued at $1 million is generally comparable to a single-family house valued at $5 million or more.

That explains why Tribeca owners who never thought of their homes as five-million-dollar properties received letters. In Q3 2026, Tribeca's median recorded sale was $3.67 million across 58 transactions, and the condo median was $3.6 million. A typical sale price says little about whether a given unit crosses the line. The figure that matters sits in DOF's records and was published in a supplemental market value roll on July 24, 2026. Appearing on that roll does not mean a unit owes the surcharge.

A threshold with a cliff

The rate schedule is in Tax Law §1353, and it changes completely partway through:

Under DOF's final rule, once a unit is over the threshold, the rate applies to its entire value and not just the portion above the line. The arithmetic follows from the schedule. A unit DOF values at $1,000,000 would face $40,000 a year at 4%. A unit valued just under $1,000,000 would face nothing. At a $5.1 million DOF value, 6.5% comes to $331,500 a year.

The surcharge is also kept separate from the property tax itself. Ordinary abatements, credits and exemptions don't reduce it. In a Tribeca building where an owner is used to a lower bill because of an abatement, the surcharge is calculated as if the abatement weren't there.

This cliff explains some of the behavior DOF's own page points owners toward. Anyone who thinks DOF valued the unit too high can appeal to the NYC Tax Commission. An owner who is challenging the value can also ask the Commission to decide the primary residence question. Under this structure, lowering a valuation below $1 million doesn't just trim the bill. It removes the charge entirely.

The two years at the high rates end in 2028

Starting July 1, 2028, §1351 defines condo value differently. Phase-two market value must be based on sales of comparable condo or co-op units, without the restrictions in Real Property Tax Law section 581 that shape the current figure. Put simply, the valuation moves closer to what apartments actually sell for. To match, the threshold rises to $5 million and the rates fall to the 0.8% to 1.3% range that already applies to houses. The statute also carries a repeal date of June 30, 2031.

So the steepest condo and co-op rates apply only to the first two fiscal years, and they run on a valuation method the law itself replaces in 2028. Someone buying a Tribeca apartment in late 2026 as a part-time home is looking at two distinct cost regimes over the first several years of ownership. The 2028 figures will depend on revaluations that haven't happened yet.

Why Tribeca's new construction falls outside it, for now

The law excludes two kinds of property. One is a unit in a building that needs a temporary or permanent certificate of occupancy and doesn't have one yet. The other is a condo or co-op unit still held by the sponsor that filed the offering plan. Once the sponsor sells the unit, the exclusion ends.

Tribeca has very little sponsor inventory right now. In September, CityRealty reported that sponsor inventory at 108 Leonard was more than 90% sold. The building still recorded six contracts totaling $25.1 million over the summer. At 111 Murray, the sponsor's availability page lists one residence, PH1, at $33,950,000. Related Companies' 70 Vestry currently shows no active new-development units. Across Manhattan in Q3 2026, sponsor listings dropped 22% from a year earlier to 564 units, the lowest level since the fourth quarter of 2012.

The next large Tribeca project is still a construction site. Tribeca Citizen reported on October 16 that 65 Franklin is well underway. Sky Equity Group is the developer and COOKFOX Architects designed the 24-story building, which will have 106 condominium units. Sales are expected to launch next year, and construction is expected to take two years. As long as it has no certificate of occupancy, the building can't be charged. Units the sponsor still holds stay excluded after that. A buyer's unit enters the surcharge framework only once the buyer closes, and by then the condo phase-two rules starting in July 2028 may already apply.

Where the charge lands: shareholders, leases and settlements

Co-ops don't receive separate bills for each unit. The surcharge goes on the cooperative's property account, and the co-op collects the share attributable to a taxable unit from that unit's shareholder. In Brick Underground's Q3 market report, brokers described concern about the administrative burden on co-op boards and about who will make up the future resale pool. One said the tax was "fueling a shift toward condos."

Residency is judged as of the January 5 taxable-status date before each fiscal year. A unit can qualify through the owner, a close family member, or a person renting under a bona fide arm's-length lease of at least one year. The statute defines immediate family as a spouse, child, sibling, parent, grandparent or grandchild. A unit owned by an entity can qualify through holders of a majority interest. Because a lease can satisfy the test, the surcharge now shows up in rental terms. In the same Real Deal article, attorney Pierre Debbas said he advises landlord clients to have tenants indemnify them if a tenant's absence triggers the charge. Another downtown tenant handled a last-minute rider by having a partner who would live in the apartment full time sign the lease.

It has also come up in divorces. The Real Deal reported in September on a settlement involving a Tribeca co-op it described as valued at more than $5 million. One spouse wanted to keep the apartment for visits to the city and wanted the other spouse to pay the expected annual 6.5% surcharge. The attorney on the case said the tax had come up at least 10 times with her clients.

Where things stand heading into November

The exemption application deadline for 2026-27 was October 13, 2026. The Real Deal reported on October 15 that DOF first notified more than 17,000 owners. It received more than 11,000 exemption applications and granted more than 6,800 exemptions. Counting exemptions and errors caught through tax records, nearly 9,000 owners have been dropped. State officials had projected $500 million a year from 13,000 homes.

Three court actions are pending:

1. In O'Brien v. City of New York, homeowners challenged how the city rolled out the notices. They did not challenge the statute. A Richmond County justice ordered the rollout redone on September 29. The city appealed, and according to a Sullivan & Cromwell tax policy update, the Appellate Division, Second Department stayed that ruling on October 6, which lets implementation continue while the appeal is pending. The court's scheduling order set briefing to finish October 21 and gave no date for oral argument.
2. Ross v. State of New York, filed in Suffolk County Supreme Court, challenges Article 30-C on constitutional grounds, including claims of discrimination against nonresidents. As of October 9, the state was asking to move the case to New York County.
3. A third suit, brought by homeowners and a city co-op and reported by amNewYork, challenges the statute's retroactive taxable-status date and the liabilities it could create for co-ops.

With the stay in place, DOF still says charges will appear on the bill due January 1, 2027.

FAQ

Does a Tribeca condo priced at $3 million automatically owe the surcharge? No. For 2026-27 and 2027-28, the test is the unit's DOF market value, and that number differs from the sale price. A unit is exempt if it's the primary residence of the owner, a qualifying family member, a majority interest holder, or a tenant.

What documents does DOF accept as proof of primary residence? For each occupant, DOF asks for a recent federal or state tax return or DMV-issued identification. Tenant claims also need a lease and other rental records, and entity owners must document majority interest.

Can an owner who missed the October 13 deadline still contest? DOF's page directs owners who disagree with its valuation to the NYC Tax Commission. Owners who are denied an exemption can also appeal there.

This post is general information. It is not legal, tax or financial advice, and owners and buyers should confirm how the surcharge applies to them with their own attorney or tax advisor.

For a Tribeca purchase or a part-time residence, the useful starting point is the unit's DOF value, its co-op share allocation if it's a co-op, and how each fits under both rate schedules.
