Mott Haven.

Three structural factors: (1) older housing stock — most private apartment buildings predate 1960 with aging systems; (2) deep rent-regulated supply where rent caps constrain owner repair budgets; (3) significant NYCHA presence with chronic maintenance backlogs. The result is genuinely higher per-building counts than NYC averages, not a measurement artifact.

Yes — Mott Haven Houses, Mitchel Houses, Patterson Houses, and several smaller NYCHA developments appear in our HPD-violation index. NYCHA has its own internal complaint and resolution process; the audit flags BBLs with NYCHA ownership. NYCHA cannot be rented privately — applications go through NYCHA directly.

On per-unit open-violation density, yes — post-2010 affordable-housing construction in Mott Haven carries much lower counts than the surrounding pre-war stock. Several specific buildings have accumulated DOB construction-phase violations or façade filings worth checking individually. The audit's BBL-level data separates the two.

A large share of pre-1974 6+ unit Mott Haven walk-ups are rent-stabilized through standard rules. Several post-2010 affordable buildings carry stabilization or other affordability terms through LIHTC, 421-a, or Mitchell-Lama programs. The audit's DHCR + tax-program check shows specific status before signing.

Open-violation counts above 200 are common in older Mott Haven rent-stabilized buildings and don't automatically signal an unsafe property. What matters is the class breakdown: class A (non-hazardous cosmetic) violations can sit open for years; class C (immediately hazardous — no heat in winter, lead paint with young children, severe vermin) are serious. The audit shows the breakdown.
