Three official areas, read one at a time
This page reads three of the city's neighborhood tabulation areas one at a time, using the city's tax-lot file (PLUTO). In the Upper East Side-Carnegie Hill area it counts 40,064 residential units on 2,249 lots: co-op buildings hold 50.6% of them, condominiums 18.2%, elevator rentals 16.5% and walk-ups 9.0%, and 58.3% of units predate 1940. In the Upper East Side-Yorkville area it counts 50,986 units on 1,388 lots, with elevator rentals at 33.0%, co-ops 26.9%, walk-ups 24.2% and condos 14.4%; there, 37.5% were built before 1940, 39.0% from 1940 to 1979 and 22.2% since. For the city's Upper East Side-Lenox Hill-Roosevelt Island area, figures including Roosevelt Island show 60,306 units, 31.6% of them co-op and 53.6% built between 1940 and 1979.
In the Census Bureau's 2020–2024 survey, ZIP code tabulation area 10028 shows 10,113 (±1,130) owner-occupied homes among 26,288 occupied units, roughly 38% (table B25003), and 11,499 (±1,232) units built in 1939 or earlier (table B25034). Shareholders and condo owners both count as owners there.
The townhouse side
One-family houses hold 1.6% of units in the Upper East Side-Carnegie Hill area and two-family houses 0.7%. A masonry townhouse of this type typically needs attention at the roof and parapets, the front and rear walls, cornice and lintels, the areaway drain, cellar dampness, the heating plant and the electrical service, and any private elevator should be checked against its own inspection paperwork.
Nine landmark designations
LPC's records put nine historic-district designations on the Upper East Side's three official areas:
- Upper East Side Historic District, designated May 19, 1981
- Upper East Side Historic District Extension, designated March 23, 2010; its Area I begins at East 75th Street and the eastern curbline of Lexington Avenue
- Metropolitan Museum Historic District, designated September 20, 1977
- Carnegie Hill Historic District, designated July 23, 1974
- Expanded Carnegie Hill Historic District, designated December 21, 1993; nine of its buildings lie in the city's East Harlem (South) area
- Park Avenue Historic District, designated April 29, 2014
- Hardenbergh/Rhinelander Historic District, designated May 5, 1998, on Lexington Avenue at East 89th Street
- Treadwell Farm Historic District, designated December 13, 1967
- Henderson Place Historic District, designated February 11, 1969, by East 86th Street and East End Avenue
Treadwell Farm lies in the city's Upper East Side-Lenox Hill-Roosevelt Island area and Henderson Place in its Upper East Side-Yorkville area; the other seven are in the Upper East Side-Carnegie Hill area, except for those nine buildings. The commission regulates property "after designation" (about LPC), and exterior work, from window replacement to rooftop additions, generally needs an LPC permit. A buyer should ask which exterior changes were made and whether each was permitted.
Zoning written for Fifth, Park and Madison
The Special Park Improvement District (ZR 92-00, last amended 4/23/1973) exists "to preserve and protect the unique character and architectural quality of the residential part of Fifth Avenue and Park Avenue which includes many landmarks and other cultural buildings." Its sections include 92-22, "Mandatory Front Building Walls Along Certain Street Lines," and 92-23, "Special Height Limitation." The Special Madison Avenue Preservation District (ZR 99-00) aims "to preserve and enhance street life by promoting specialty shops at street level."
A pre-war co-op unit: scope and records
In a co-op, the board controls the building and its money, and neither is part of the walkthrough. The visit covers the apartment: panel, circuits and outlets; supply and drain at each fixture; windows; the radiator, convector or through-wall unit serving the rooms; exhaust; and staining that suggests water from above or through a masonry wall. A pre-war building may have original risers and steam heat, so ask the board when the risers were last replaced and what the heating plant's age is. For the plan itself, the Attorney General's offering plan database lists submitted co-op and condo plans and amendments.
Those original risers matter for gas as well. The three official areas sit in Manhattan Community District 8, where DOB's Local Law 152 schedule keeps the current gas-piping window open through 31 December 2026 and places the following one in 2030; confirm the district for the exact address. Only R-3 buildings, one- and two-family homes among them, sit outside the rule, so a co-op's GPS2 certification, and any riser work that an inspection under it prompted, belong on the list of papers to request from the board.
Flood labels and stations
On both FEMA's effective and preliminary layers, AE zones run along the East River shoreline of the city's Upper East Side-Yorkville area. For the city's Upper East Side-Lenox Hill-Roosevelt Island area, FEMA's maps also show AE zones along the shoreline, with VE zones added on the preliminary maps; that result includes Roosevelt Island's shoreline. For the Upper East Side-Carnegie Hill area, FEMA's maps give the label Zone X, which is not a statement that a building there is safe from flooding; look up the building's address on FEMA's Map Service Center. Insurance rates still follow the 2007 effective maps (NYC flood maps). The state's station data lists 68 St-Hunter College, 77 St and 86 St on the Lexington Avenue line, and Q stops at 72 St and 86 St on the Second Avenue line. Gracie Mansion is an individual landmark in the Upper East Side-Yorkville area, according to LPC's landmark data.
