Harlem has Manhattan's deepest pre-war rent-stabilized stock and the borough's second-largest NYCHA concentration after the Lower East Side — roughly 25,000 NYCHA units sit between Central Harlem and East Harlem. The compliance pattern reflects both: rent-stabilized private walk-ups carry classic heat, plumbing, and lead violations driven by tight repair budgets, while NYCHA developments carry their own chronic-maintenance backlog. Newer construction along Frederick Douglass Boulevard and the 125th Street corridor shows lower per-unit violation rates. The list below ranks Harlem buildings by current open HPD violations.

Harlem FAQ

Frequently asked about Harlem buildings.

Which Harlem ZIP has the most building violations?

ZIPs 10027 (Central Harlem, including Strivers' Row and the 125th Street corridor) and 10037 (East Harlem) tend to carry the highest per-building open-violation counts in Harlem, driven by older landlord-managed walk-ups and significant NYCHA presence. 10030 (West Harlem / Hamilton Heights edge) trends lower thanks to newer 1990s-2000s infill construction.

Is most of Harlem rent-stabilized?

A large majority of pre-1974 Harlem walk-ups are rent-stabilized through standard 6+ unit rules. Newer construction along Frederick Douglass Boulevard and infill on 125th Street is mostly market-rate unless a 421-a or LIHTC abatement attached affordability terms. The audit's DHCR check shows the specific building's status before you sign.

How do I check if a Harlem building is NYCHA?

NYCHA buildings appear in PLUTO with owner = New York City Housing Authority. The audit cross-references this on every BBL. If you're applying for a NYCHA apartment, the application process goes through NYCHA directly, not through a private listing. Renting a NYCHA unit privately without NYCHA's sublet program is not generally permissible.

Should I worry about lead paint in a Harlem walk-up?

Yes — most Harlem walk-ups predate 1978 and are subject to NYC Local Law 1 lead remediation when a child under 6 is in the unit. Several Harlem landlords carry significant open class-C lead-paint violations in our index. If you're moving in with young children, request the landlord's most recent lead inspection records as part of the lease process and check the audit for any open class-C lead flags.

What's the compliance picture for 125th Street corridor buildings?

The 125th Street corridor mixes pre-war walk-ups, 1990s-2000s mid-rise infill, and a smaller tier of post-2015 podium buildings. Open-violation density is mixed — the older walk-ups carry the standard pattern, the infill buildings carry fewer per-unit, and several of the newer podium buildings have accumulated DOB construction-phase or façade violations. Always pull the BBL.
