Seeing what the city's own systems can't

NYCHA buildings score near-zero on standard distress metrics because the city doesn't fine itself, doesn't sue itself, and doesn't put its own buildings on lien lists. Sillview Flare uses a separate tenant-conditions model that measures what residents actually experience.

Distressed
Top cluster: 9 of the 10 worst-scoring NYCHA buildings sit on two blocks in Harlem — W 143rd–144th Street and Adam Clayton Powell Blvd. Complaint intensity, violation density, and active litigation all converge in the same two-block radius.
50% weight

Complaint Intensity

311 and HPD complaint volume per unit over 90 days, with acceleration vs. prior period. The primary signal of tenant-experienced conditions.

20% weight

Violation Density

Open HPD Class B/C violations per unit. Even when the city doesn't issue ECB fines to itself, inspectors still document hazardous conditions.

15% weight

Physical Condition

Building age, emergency repair history, and maintenance indicators from DOB and HPD inspection records.

15% weight

Development Contagion

Average distress of other buildings in the same NYCHA development. Systemic management failures affect entire complexes, not just individual buildings.

What it solves

How it's different from what you have now

Current Process

HPD currently assembles distressed building lists manually from siloed systems. Each agency sees its own slice — violations here, tax liens there, complaints elsewhere.

With Sillview Flare

Sillview automates this weekly. 22+ sources, one ranked list, updated continuously. Portfolio-level analysis catches the landlords that single-building views miss.

Public Advocate's Worst Landlords

The annual Worst Landlords list uses a single metric. Valuable, but narrow. It captures a moment in time.

Sillview's Approach

22+ data sources with portfolio-level analysis, updated weekly. Track deterioration over time, not just a single snapshot.
