Every condo and co-op in New York is tested against the pied-à-terre surcharge on its assessed value — the income-derived DOF figure, not the price the unit would sell for. In 111 West 57th Street (Steinway Tower), that test splits the building: 80% of units clear the $1,000,000 threshold and owe 4%–6.5% of assessed value above it 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 Billionaires' Row: a large share of homes in buildings like this are second residences — exactly what the surcharge targets. 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.
