The record, live: Manhattan

Mold violations in Manhattan.

mold violations cited in Manhattan in the trailing 3 years, read from the city’s open-data API at this deploy.

How a violation reaches this record

Most rows here start with a tenant's call to 311. HPD schedules an inspection, and if an inspector confirms the condition, HPD issues a violation and mails the owner a Notice of Violation. From that point the violation is searchable on HPD Online by address. It stays on the public record used throughout this site until the agency accepts a correction or the agency closes the case another way. See how HPD, DOB, and OATH/ECB fit together.

The monthly pattern

Mold violations HPD has cited in Manhattan, by calendar month, over the last 36 complete months so every month is counted across the same three years. August carries the most at 2,074. December carries the fewest at 1,280.

By class

HPD sorts every mold violation into one of three classes, and the class sets the correction window and how urgently an owner must act. In Manhattan, HPD has issued 1,781 Class C mold violations, immediately hazardous, correct within 24 hours. It has issued 8,826 Class B, hazardous, correct within 30 days, and 8,682 Class A, not hazardous, correct within 90 days.

Class C is 9.2% of the 19,289 mold violations recorded in Manhattan.

The certification record

Of 1,781 Class C mold violations in Manhattan, 275 have ever been certified corrected, 15.4%. Correction took a median of 33 days and a 90th percentile of 262 days. 1,097 have sat open more than a year with no certification on file.

1.8% of mold violations in Manhattan are currently marked Not Complied With, HPD's status once the certify-by date passes without an accepted certification.

After a certification is filed

Filing a certification does not automatically close a case. If HPD reviews the paperwork and finds it insufficient, the case moves to Defect Letter Issued and the owner must refile. If a reinspection later finds the condition still uncorrected despite a certification on file, the case moves to Invalid Certification. A certification accepted after the certify-by date is marked NOV Certified Late rather than on time; one accepted before it is marked NOV Certified On Time. Each of these statuses carries its own page in the status glossary, decoded in plain language.
