Code: COC – Certificate of Compliance (DOB equipment approval document)
Description: (Certificate of Compliance) is the DOB document that confirms specific service equipment — such as a boiler, elevator, sprinkler system, or other regulated building system — was inspected, tested, and approved before it is put into use. It is not a violation correction filing and has nothing to do with a person's professional qualifications; it applies only to equipment and systems.
Practical Meaning: If your building has a boiler, elevator, sprinkler, or other regulated system, DOB requires a Certificate of Compliance to confirm that the equipment was properly inspected and approved before use. A missing or expired COC-Compliance can result in a violation, a required re-inspection, and the equipment being taken out of service until a new certificate is issued..
Where You May See It: You may see this referenced in DOB BIS or DOB NOW under your property's job filings, in a DOB inspection letter or violation notice related to a specific building system, or requested by your engineer, Special Inspection Agency, or contractor when closing out a permitted equipment installation.
Why It Matters: Without a valid Certificate of Compliance, DOB considers the equipment unapproved, which can trigger violations, stop further work, or lead to fines and forced shutdowns. Do not confuse this with COC-Correction (Certificate of Correction), which is a filing that closes a violation, or with COC-Competence (Certificate of Competence), which is a personal professional credential.
