About the data
How the figures are calculated
- Recorded sales
- Property sales within 820 ft (250 m) in 12 months, with the median price and the latest sale. For the lot itself, its own recorded sales in that time. Source: NYC Citywide Rolling Calendar Sales.
- Construction
- Building permits within 820 ft (250 m) in 12 months, and the nearest new building. Source: DOB permits and job filings.
- Sidewalk sheds
- Sheds within 820 ft (250 m), and the oldest one still up.
- Flood record
- Whether lots nearby sit in a FEMA flood zone, the nearest FloodNet street sensor and its recorded floods, and the sea level rise at which the spot falls below the high-tide line (NOAA).
- Landmarks
- Historic districts and designated landmarks near the lot. Source: Landmarks Preservation Commission.
- The neighborhood
- Public schools, the nearest subway stations and the air, as yearly averages from the NYC Community Air Survey.
How to read it
- Recorded sales are closed deals, not listings. A median price describes sales nearby, not what a home is worth.
- A school dot is not your zoned school. Check zoning with the Department of Education.
- The sea level layer is NOAA screening data: the reach of high tide on a higher sea, not storm surge.
