Building Risk Rankings
Bronx Building Risk Rankings
The Bronx has the highest per-capita open-violation rate of any NYC borough — driven by older rent-regulated housing stock, the largest concentration of NYCHA developments per square mile in the city (~22% of all NYCHA units sit in the Bronx), and chronic underinvestment in heat, plumbing, and lead remediation at many private rent-stabilized buildings. Concentrated areas include the Grand Concourse corridor, Soundview, Highbridge, and parts of Morrisania. The list below ranks Bronx buildings flagged for significant open HPD violations — each entry links to a free preview audit covering compliance, financials, and neighborhood signals.

Frequently asked about Bronx buildings
Why does the Bronx have more open violations than other boroughs?
Three structural factors: (1) older housing stock — much of the Bronx's apartment inventory predates 1960 and faces aging building systems; (2) significant rent-regulated supply where rent caps limit owner repair budgets; (3) the largest concentration of NYCHA units per square mile in NYC. The result is genuinely higher open-violation counts per building on average — not a measurement artifact.
How do I check if a Bronx apartment is in NYCHA?
NYCHA buildings are tagged in PLUTO as owner = NYCHA or NY City Housing Authority. Our 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 involvement is generally not permissible.
Are rent-stabilized Bronx buildings worse for violations?
On average, rent-stabilized buildings carry higher open-violation counts than market-rate buildings — partly because rent caps constrain owner repair budgets, partly because rent-stabilized tenants tend to file more complaints (they have stronger renewal protections so the cost of complaint is lower). Rent stabilization is still a strong tenant benefit; the violation pattern is something to monitor, not a reason to avoid.
What does '100+ open violations' mean for a Bronx building?
Open-violation counts above 100 are common in older Bronx rent-stabilized buildings and don't automatically signal an unsafe property. What matters is the class breakdown: class A (non-hazardous) violations can sit open for years without affecting day-to-day livability, while class C (immediately hazardous, e.g., no heat in winter, lead paint in a unit with a child under 6) are serious. The audit shows the breakdown.
Which Bronx neighborhoods have the highest violation counts?
Mott Haven, Morrisania, Soundview, Highbridge, and Grand Concourse corridor neighborhoods carry the highest per-building violation counts in the Bronx. Riverdale, Throgs Neck, and other lower-density Bronx neighborhoods show meaningfully lower violation rates. Always check the specific BBL — even high-violation neighborhoods contain well-managed properties.
