NYC DOB Forms: A Homeowner’s Guide to Notices, Corrections, and Challenges

Example of an older NYC DOB Certificate of Correction document
Older Certificate of Correction document. Current requests are submitted through DOB NOW.

A notice from the NYC Department of Buildings does not always require the same response. This guide helps homeowners understand which forms or online requests relate to correcting a violation, challenging a summons, or appealing a decision. Start by reading your notice and identifying the agency, violation or summons number, hearing date, and any correction deadline.

Correcting a condition and challenging a summons are different processes. A Certificate of Correction tells DOB that the violating conditions have been corrected. It does not argue that the summons was wrong. To contest a DOB-issued OATH summons, follow OATH’s hearing instructions and present evidence supporting your defense. Do not assume that repairs or a submission to DOB cancel your hearing obligations. This guide focuses on DOB-issued OATH summonses and related correction requests; other city notices may require different procedures.

Understand your options: correction documents, hearings, and review requests.

AEU2 was the Certificate of Correction form, and AEU20 was the supporting statement describing the correction work. DOB now requires the information to be entered directly in the online Certificate of Correction request instead of uploading these forms. Prepare supporting records, such as photographs, receipts, and relevant permits or inspection documents. Submitting a request is not the same as receiving approval, and correction does not automatically cancel every penalty. See the official DOB Certificate of Correction instructions.
