What is an ECB violation?

An ECB violation is a summons. It is issued when an inspector finds a breach of the city's construction, zoning, electrical or maintenance codes, and unlike an ordinary notice it carries a monetary penalty and a hearing date. ECB stands for the Environmental Control Board, whose hearings are now held at the Office of Administrative Trials and Hearings.

What one actually looks like

A real summons issued on 30 July 2026, with the field names the city's dataset uses:

FieldValue
ecb_violation_number39198397R
issue_date20260730
severityCLASS - 1
violation_typeConstruction
infraction_code1102
penality_imposed2500
ecb_violation_statusACTIVE
hearing_statusPENDING
hearing_date20261014

The misspelling in penality_imposed is the city's, not ours — it is the real column name, and anyone querying the data has to spell it that way.

The severity classes

ECB summonses are graded by how serious the condition is. Across the full dataset the classes fall out like this:

SeveritySummonses
Class 1 — immediately hazardous490,580
Class 2 — major614,165
Class 3 — lesser54,905
Older labels: Hazardous / Non-Hazardous / Unknown667,953 combined

Those last labels are a legacy vocabulary still attached to older rows. A file that has been running for decades accumulates more than one way of saying the same thing, and it is worth knowing before you conclude that a building has no classified violations.

This is where the "class" confusion starts

Class 1, 2 and 3 belong to ECB summonses. They are not the same as HPD's letter classes, which grade apartment conditions on an A/B/C scale — see HPD violation classes. And they are not a property of an ordinary DOB violation, which is categorised a different way again. Three agencies, three vocabularies, one building.

How it ends

Every summons is answerable at a hearing, and the outcome is recorded. The commonest results across the dataset:

Hearing resultCount
In violation679,464
Dismissed297,942
Written off243,998
Cured, in violation214,174
Default (no appearance)162,858

Nearly 300,000 summonses were dismissed. That is the single most important number on this page: an issued summons is an allegation until a hearing decides it, and a meaningful share do not survive one. Default is worth understanding too — it means nobody turned up, and the penalty is imposed without the case being argued.

Reading it fairly

An open ECB violation on a building tells you the city cited a condition and the matter has not been resolved. It does not tell you the current state of the building, whether the work was since done, or anything about the people who live there. Records also lag: a condition fixed last week may still read as open. Treat it as a documented event with a date, which is exactly what it is.

Questions people ask

What is an ECB violation in NYC?

A summons issued for a breach of the city's construction, zoning, electrical or maintenance codes. It carries a monetary penalty and a hearing date at OATH, which distinguishes it from a notice that simply asks for a repair.

What is the difference between a DOB violation and an ECB violation?

A DOB violation is a departmental record that a condition was found. An ECB violation is a summons with a penalty attached, decided at a hearing. The same inspection can produce both.

What do ECB Class 1, 2 and 3 mean?

Class 1 is immediately hazardous, Class 2 major, Class 3 lesser. Older rows in the city's file use a different vocabulary - Hazardous, Non-Hazardous and Unknown - for the same idea.

Does an ECB violation mean the building is unsafe?

Not by itself. It records that an inspector cited a condition on a date. Across the city's own data nearly 300,000 summonses were dismissed at hearing, and records can lag repairs that have already been made.

What happens if nobody answers an ECB summons?

The case goes into default and the penalty is imposed without the matter being argued. The city's file records over 162,000 defaults.
