Built mostly between 1940 and 1979
East Harlem appears in city data as two neighborhood areas, East Harlem (South), coded MN1101, and East Harlem (North), coded MN1102. In the city's tax-lot file (PLUTO), 46.0% of MN1101 units and 39.7% of MN1102 units are in buildings from 1940–79 (each NTA's figure). East Harlem (South) has 28,466 homes on 703 residential lots, split among elevator rentals at 47.4 percent, walk-ups at 20.0 percent, co-ops at 18.2 percent and condos at 12.5 percent. East Harlem (North) has 31,253 homes on 1,466 lots: elevator rentals 55.5 percent, walk-ups 21.5 percent, condos 9.3 percent and co-ops 6.5 percent, with 28.0 percent of units in buildings from 1980 on.
The Census Bureau's 2020–2024 American Community Survey counts 33,660 occupied homes in ZIP code tabulation area 10029, roughly 7 percent owner-occupied, and 15,655 in ZCTA 10035, roughly 11 percent. Co-op shareholders are part of those owner counts. In 10035 the year-built table puts about a quarter of housing units in buildings from 2000 or later and about a quarter in buildings from 1939 or earlier.
Those figures point a buyer toward buildings of the 1940s to 1970s, or newer ones, and toward the records that follow buildings of that size.
Facades on a five-year cycle
The Department of Buildings requires owners of properties higher than six stories to have exterior walls and appurtenances inspected every five years and to file a technical report. Each report classes the facade as Safe, as safe with a repair and maintenance program (SWARMP), or as Unsafe. A SWARMP item left uncorrected by the next cycle must be reported as unsafe. Under the facade rule itself, unsafe conditions must be corrected within 90 days of the report being filed; where the repair is too large for that, the qualified exterior wall inspector who wrote the report must recommend a longer timeframe. When hazardous conditions turn up, the Department says sidewalk sheds and other pedestrian protection go up.
Cycle 10 filing windows depend on the last digit of the tax block, per the Department's February 2025 service notice: a block number ending in 4, 5, 6 or 9 has a filing window of February 21, 2025 to February 21, 2027; one ending in 0, 7 or 8 files from February 21, 2026 to February 21, 2028; and 1, 2 or 3 follow a year later. Filings sit in DOB NOW: Safety, per the facade compliance page. Ask the managing agent which classification the last report gave.
Elevators and emissions
An elevator building depends on its lifts. The elevator compliance rules call for an annual periodic inspection, an annual CAT1 no-load safety test, and a CAT5 test no later than five years after the month of the last one; the Department's page also says elevators must be inspected and tested twice a year. Request the dates and any open defects.
Emissions limits are the other building-wide cost to understand. Local Law 97 covers a building over 25,000 gross square feet. It also reaches a tax lot holding two or more buildings that add up to more than 50,000, and condo buildings governed by a single board that add up to more than 50,000. The limits began in 2024 and tighten in 2030, and the Department's Covered Buildings List reflects its records as of March 2026. Ask whether the building is on that list and how it plans to meet the limits.
What the visit does inside the apartment
For the unit, the visit checks the electrical panel and circuits, outlets near water, supply lines, shut-offs and drains at each fixture, windows and their hardware, the radiators or through-wall units that heat and cool the space, bathroom and kitchen exhaust, and ceilings and walls for staining from above or from the exterior. Buildings of the 1940s to 1970s commonly have metal-framed windows, original risers and through-wall air-conditioner sleeves, each worth a close look where water can get in; those are traits of the type, not findings about any building. The visit cannot assess the roof, facade, elevators, boiler, board or finances.
Zoning and landmarks
The Special East Harlem Corridors District, in a chapter last amended November 30, 2017, sets as its first purpose "to encourage and guide the development of East Harlem as a dynamic mixed-use neighborhood". Section 138-041 of that chapter is titled "Applicability of Article IX, Chapter 5", the Special Transit Land Use District chapter. Part of East Harlem (North) falls in the Special 125th Street District. Part of the Expanded Carnegie Hill Historic District (LP-1834, December 21, 1993), whose building entries run up to the block between East 98th and 99th Streets, lies within the city's East Harlem (South) area, and most types of alterations there need Landmarks permits.
Stations and flood maps
The state's MTA station table places 96 St on the Q, the Second Avenue line's northern last stop and ADA-listed, in East Harlem (South), with 103 St and 110 St on the 6, neither ADA-listed. In East Harlem (North) are 116 St on the 6, not listed, and 125 St on the 4, 5 and 6, listed as accessible.
Both official areas meet Zone AE and Zone X on FEMA's effective and preliminary flood data. Whether a tower near Lexington Avenue sits in one zone or another is a question for the address alone, which FEMA's Flood Map Service Center will look up.
From East New York, Brooklyn, Masum Rumi of Rumi Home Inspections can meet you at the unit, explain what he sees in Bangla or English, and send the report before the day is out. Use the contact form and mention the building's age and height; the general inspection page lists what the report covers.
