What a DOB Class 3 (Lesser) violation means

A DOB Class 3 — "Lesser" — is the lowest-severity DOB violation tier. Many Class 3 summonses are for paperwork, posting, and site-housekeeping issues — violations that must be cured and paid, but that do not threaten life safety. They still show up on the building's record and can attract lender, insurer, and buyer attention, so closing them cleanly matters.

This guide explains what Class 3 covers, the OATH path, and how owners typically close them out. Educational only — not legal advice.

What this means

The Class 3 tier captures the tail end of the DOB penalty schedule — everything not serious enough to be Class 1 (immediately hazardous) or Class 2 (major). The NOV is usually an OATH / ECB summons with a hearing scheduled and, for most offenses, a stipulation / cure option.

Class 3 conditions you see often:

• Minor signage or posting failures on a DOB-permitted site (e.g., missing permit posting).
• Administrative defects in permit paperwork or as-built documentation.
• Minor equipment-use permit lapses — cranes, derricks, certain elevators.
• Minor housekeeping issues at a construction site.
• Tenant Protection Plan paperwork gaps that are not themselves hazardous.

"Lesser" does not mean "ignore." Class 3 violations remain on the building's DOB record until you file a Certificate of Correction and DOB accepts it. They can show up in lender, insurer, and buyer diligence even after the penalty is paid.

Common causes

• Minor signage or posting failures on a construction site
• Administrative defects in permit paperwork or as-built documentation
• Minor equipment-use permit lapses
• Minor housekeeping issues at a DOB-permitted site
• Paperwork gaps in a Tenant Protection Plan that are not themselves hazardous

Timeline

• Issued. The summons is served at the site or sent to the address of record.
• Hearing scheduled. Typically 6–8 weeks out at OATH.
• Stipulation window. If offered, the stipulation must be signed before the hearing date; you admit, cure, and pay a reduced amount.
• Hearing. Contested hearings proceed at OATH; for many Class 3 offenses, mail-in defense is available.
• Penalty imposed. OATH decision states the penalty.
• Certificate of Correction. Cure the underlying condition and file the Certificate with DOB.

Penalties

Class 3 civil penalties are the lowest of the three DOB tiers but still meaningful.

• Base penalty: typically $625 per Class 3 offense as a baseline (verify current schedule).
• Stipulation discount. Signing a stipulation usually reduces the penalty materially compared to the contested default.
• Paperwork sticks. Closing the penalty does not close the violation; the Certificate of Correction is a separate filing.

How it typically gets resolved

1. Read the summons. Confirm the hearing date, rule cited, and the penalty on the face of the summons.
2. Cure quickly. Most Class 3 conditions are curable in days — post the permit, correct the paperwork, clean up the site.
3. Stipulate if offered. Stipulations resolve the case faster than a hearing and usually reduce the penalty.
4. File the Certificate of Correction if the summons requires one.
5. Track closure. Confirm the violation shows closed in DOB NOW / BIS. If it remains open after the Certificate is filed, follow up with DOB.

When to hire a pro

Much Class 3 work is in-house. Bring in outside help when:

• The cure requires a DOB NOW filing or permit amendment — an expediter saves time.
• The summons is tied to a larger dispute (contractor, architect, tenant action) — consult an attorney.
• The building has repeat Class 3 issues — often a procedural fix at the GC or managing-agent level will stop the pattern.
• The cure needs an RDP signature (rare for Class 3 but possible).
