How to File a Certificate of Correction (COC) with the NYC DOB — Step-by-Step Guide

Received a Department of Buildings (DOB) violation? Filing a Certificate of Correction (COC) is often the fastest way to show the DOB you fixed the problem and close the case. This guide explains what a COC is, when you need one, the documents required, and how our team at NYC Building Violation Removal & Expediting LLC can handle the paperwork for you.

What is a Certificate of Correction (COC)?

A Certificate of Correction is a formal filing to the NYC DOB that certifies the condition cited in your violation has been corrected. When accepted, the DOB marks the violation as corrected — preventing additional enforcement actions and helping clear your property's record.

When should you file a COC?

• If you received a DOB summons and have corrected the cited condition (for example: unsafe scaffolding, electrical issues, or work without a permit).
• Before or on the compliance date to avoid extra fines, re-inspections, or hearings.
• Immediately for Class 1 (hazardous) violations — delays can lead to daily fines or stricter enforcement.

Required documents & proof

A complete COC packet improves the chance of fast approval. Typical items include:

• AEU-2 (Certificate of Correction affidavit) or alternate DOB form if specified.
• Statement in Support (AEU-20) explaining what was corrected, when, and by whom.
• Proof of correction: dated receipts, invoices, permits, and clear before/after photos labeled with the summon number and address.
• Proof of paid penalties (if applicable) and any required contractor licenses or trade affidavits.

How to file — step by step

1. Correct the violation. Finish repairs or obtain the required permit/inspection.
2. Gather supporting documentation. Photos, receipts, permits, contractor statements, etc.
3. Log into DOB NOW. Use your NYC.ID and navigate to the Certificate of Correction submission section.
4. Upload documents & submit. Include the summons number, address, and all labeled evidence.
5. Monitor status. Check DOB NOW for approval or disapproval and respond quickly if DOB requests more information.

Tips to avoid COC rejection

• Label all photos with address, summons number, and date.
• Include contractor details and invoices showing the work performed.
• Make sure permits (if required) are filed and clearly referenced in your packet.
• Respond promptly to DOB requests for additional information to prevent delays.

Why timely COC filing matters

Leaving a violation open can lead to repeated inspections, higher fines, OATH hearings, and complications when selling or refinancing. Filing a correct COC closes the loop and helps keep your property record clean.
