Updates March 1, 2026

178 commits since the last update. Most of it was under-the-hood accuracy work driven by your reports. Six new data sources, rebuilt scoring components, human-readable event details, and address-based URLs. Here's what's different now.

What You See

  • Building events now show human-readable descriptions — instead of raw agency codes, you see what actually happened ("failed boiler inspection" not "DOB_VIOL_3A")
  • Every event shows detailed breakdowns: violation class, apartment number, penalty amounts, hearing status, document types — previously hidden in raw city data
  • Events are now color-coded by category: Violations, Complaints, Inspections, Permits, Legal, Financial, Health & Safety
  • PDF reports now match what you see on the website — no more confusing mismatches between web and download

Finding Buildings

  • Every building now has a clean URL based on its address — openstoop.com/building/85-bowery-manhattan instead of a 10-digit number
  • Old links still work and automatically redirect to the new address-based URL
  • Buildings with overdue elevator inspections are now flagged on the report

More Data

  • Added elevator inspection records, ACRIS real estate transactions, and HPD owner/agent contact info
  • Added 833,000 boiler registration records — you can now see if your building's boiler is registered and inspected
  • Added DOF tax lien records, DOB facade inspection reports (FISP 7-year cycles), DHCR rent stabilization registry, and Certificates of Occupancy
  • Building timelines now pull from 25 public data sources total — up from 20 at launch
  • 311 complaints filtered to building-related issues only — citywide infrastructure problems no longer clutter your building's timeline

Scoring

  • Major scoring update — we rebuilt how several components calculate building health, focusing on real evidence instead of penalizing buildings for missing data
  • Buildings with no inspection history are no longer assumed to be neglected — silence from city agencies isn't the same as problems
  • Small buildings (5 units or fewer) are now scored more fairly — they generate less city data by nature, not by neglect
  • Over 10,000 buildings that were stuck at inflated grades due to stale city records have been corrected
  • Buildings with open Class C violations (immediately hazardous — lead paint, no heat, structural danger) are now guaranteed to be flagged, regardless of what the rest of the data says
  • Dismissed violations no longer count against your building — if a complaint was cleared, it's cleared
  • Lead and mold complaints from 311 are now properly weighted — they were being silently ignored before
