The surcharge tests each unit's DOF market value — the "Market Value" line on the Notice of Property Value — against a $1,000,000 threshold. In 15 West 53 Street, 35 of 245 units (14%) test over the line, each owing a flat 4%–6.5% of its full market value for any year it is not someone's primary residence. Units below the threshold owe nothing under Phase 1 (through June 30, 2028); primary residents and units on qualifying 12-month leases owe nothing at any value.

Frequently asked questions
Does the NYC pied-à-terre tax apply to 15 West 53 Street?
It depends on the unit. On DOF's July 2026 Supplemental Market Value Roll, 15 West 53 Street has 245 condominium units with a median DOF market value of $521,056. 35 of 245 units (14%) are over the $1,000,000 DOF market-value threshold and owe the surcharge for any year they are not a primary residence; the rest owe nothing under Phase 1. The surcharge is a flat 4%–6.5% of a unit's full DOF market value once it clears $1,000,000; units below that owe nothing under Phase 1, which runs through June 30, 2028.
How much is the pied-à-terre tax at 15 West 53 Street?
It is charged on a unit's full DOF market value, not the lower assessed value on your regular tax bill. A 15 West 53 Street unit at the building's median DOF market value of $521,056 would owe about $0 per year in years it is not a primary residence, and the top-valued unit here ($4,614,451) would owe about $242,259. Across every over-threshold unit, the building's combined maximum annual surcharge is $2.4M.
Which units at 15 West 53 Street owe the pied-à-terre surcharge?
35 of 245 units (14%) are over the $1,000,000 DOF market-value threshold and owe the surcharge for any year they are not a primary residence; the rest owe nothing under Phase 1. The test is on DOF market value — the income-derived "Market Value" figure on the Notice of Property Value — not the lower assessed value. Whether a given unit actually owes in a given year also depends on use: the surcharge applies only when the unit is not someone's primary residence.
How can I avoid the pied-à-terre tax at 15 West 53 Street?
A 15 West 53 Street unit owes nothing in any of three cases: it is occupied more than half the year by you or an immediate family member as a primary residence; it is leased to a tenant on an arm's-length lease of 12 months or more; or it is sold. Conquest can model the lease-versus-sell numbers for your specific unit at no cost.
