Every condo and co-op in New York is tested against the pied-à-terre surcharge on its DOF market value — the "Market Value" line on the Notice of Property Value (an income-derived Department of Finance figure), not the 45%-of-market assessed value on your regular tax bill. In The Century, that test splits the building: 5% of units clear the $1,000,000 market-value threshold and owe a flat 4%–6.5% of their full market value for any year they are not someone's primary residence, while the rest owe nothing under Phase 1 (through June 30, 2028). Phase 2 re-tests everyone in 2028.

Owners in Central Park West: 5% of units here test over the $1M threshold, so the surcharge reaches a real share of this building. The exemptions are real, though: a unit occupied >half the year by you or an immediate family member, or leased arm's-length for 12+ months, owes nothing. The main guide covers every rule; the free check below gives you your unit's exact numbers.

Figures from the public NYC DOF assessment roll (dataset 8y4t-faws), FY 2026–27. Educational information, not tax or legal advice. The surcharge is the flat statutory rate applied to the unit's full DOF market value once it exceeds the $1M threshold. Unit designations are public record; no ownership information is shown.
