Flatiron

About Flatiron

Flatiron, as covered here, runs from 14th Street up to 25th Street, east of Sixth Avenue toward Park Avenue South. It sits between Union Square to the south and Madison Square to the north.

The neighborhood takes its name from the Flatiron Building, completed in 1902 where Fifth Avenue and Broadway cross at 23rd Street. In the late 19th century, Broadway, Fifth and Sixth Avenues here were lined with department stores, the shopping district known as Ladies’ Mile. Their cast-iron and masonry buildings now form the Ladies’ Mile Historic District, designated in 1989, which covers about two-thirds of the neighborhood’s tax lots.

Most of those commercial and loft buildings were converted to apartments from the 1970s on, and newer condominiums have been added since. The Union Square Greenmarket runs four days a week at the southern edge.

Landmarks Preservation Commission historic districts in the neighborhood include the Ladies’ Mile Historic District. Exterior changes to buildings inside a historic district need Commission approval, which is worth knowing before buying a townhouse or planning a renovation. Check any address on the LPC designations map.

Flatiron market report

From October 2025 through September 2026, NYC Department of Finance records show 200 home sales in Flatiron, with a median price of $2.27M. Half of those sales fell between $1.29M and $3.45M.

The total breaks down as 81 co-op sales, 118 condo sales and 1 sale of 1–3 family houses.

The overall median is higher than in the previous 12 months, but the co-op and condo medians moved much less (co-ops +53.2%, condos +11.6%). Most of the change in the overall figure comes from which homes happened to sell, so we don’t read it as a price trend.

The co-op median rose 53.2% year on year, on 81 sales. A swing that size usually reflects which apartments sold, not a change in what comparable apartments are worth.
