A filled month had a report to HPD; darker means more than one, and the past year is brightest. Tap one to read it. Complaints within a week count as one report. Records list complaints filed, not conditions found.
Status describes city records, not the building's condition. Tap a system for its records and sources.
These are city records, not an inspection by Blueflo. Every item shows its source and the date it was last checked.
