ACP7 asbestos filings: what an asbestos notification means
Last reviewed Oct 6, 2026 · Boilers, DEP and environmental compliance
An ACP7 is a notification filed with DEP that asbestos abatement work is planned at a building. It records the contractor, the material and the abatement method. It is a filing by a contractor, not a finding against the building, and it is not a violation.
What the filing represents
Asbestos abatement in New York City is a notified activity. Before work of a certain scope proceeds, the contractor notifies the Department of Environmental Protection, identifying the building, the material involved and how it will be handled.
The record that results is evidence that regulated work was declared and is expected to be done under the applicable controls. For an owner it is usually reassuring rather than alarming: an undeclared abatement project is the problematic case, not a declared one.
It also tells you something useful about the building’s past. A history of abatement filings indicates asbestos-containing material has been present and addressed, which is worth knowing before planning work that might disturb more of it.
Limits worth knowing before relying on this data
- It updates roughly monthly
- A project notified this week may not appear in the published data for several weeks. It is unsuitable for anything time-critical.
- It describes intent, not completion
- A notification says work was planned and declared. It does not confirm the work was carried out, or carried out correctly.
- Scope thresholds apply
- Not all work involving asbestos-containing material requires this notification. An absence of filings does not establish that no asbestos work has ever been done.
Common questions
Does an ACP7 filing mean my building has an asbestos problem?
It means asbestos-containing material was present and that regulated work was declared to address it. Whether anything remains depends on the scope of the project and what else is in the building.
Can I see what material was involved?
The published record carries the material and the abatement method along with the contractor, which is usually enough to understand what was done.
Who files it, me or the contractor?
The contractor performing the abatement files the notification. As owner you should nonetheless know it was filed, because an undeclared project is your problem too.
