Which NYC DOB Filings Require an Asbestos Survey? A Plain-English Guide
Clear Advisory / NYC filing guide
Filing plans in New York City and hitting an asbestos question you didn’t expect? You’re not alone. A missing asbestos assessment or required DEP filing can hold up a Department of Buildings (DOB) permit.
The principle is straightforward: when proposed work may disturb suspect asbestos-containing materials, resolve the assessment and filing requirements before the permit and construction stages. Which projects trigger those requirements can trip up owners, boards, architects, and contractors.
The quick answer
Demolition and alterations that disturb suspect materials commonly require an asbestos assessment and the applicable DEP filings. The scope of work, materials, and available exemptions matter. An ACP-5 is one filing route; an asbestos project may require an ACP-7 and completion documentation.
Filings that commonly require an asbestos assessment
Full and partial demolitions
Demolition requires careful asbestos review. For a full building demolition, DOB generally requires an ACP-5 with box 8(d) checked, certifying that the entire building is free of asbestos-containing material. Specific exceptions apply to certain concurrent abatement and demolition projects and emergency demolitions. Partial demolition requires an assessment of the affected scope and the appropriate asbestos documentation.
Alterations that disturb suspect materials
Alteration work that touches materials that could contain asbestos commonly triggers assessment requirements. Examples include floor tile and mastic, pipe and boiler insulation, roofing, joint compound, plaster, ceiling tile, and facade materials. Gut renovations, kitchen and bathroom renovations in older buildings, and mechanical system changes deserve early review.
Roof, facade, and enlargement work
Re-roofing, Local Law 11 / FISP facade repairs, and enlargements that cut into existing construction may disturb suspect materials. Roofing felts, flashing cements, window caulking, and other components within the work area should be considered during scoping.
Interior demolition ahead of a renovation
Even when the renovation is filed separately, interior demolition that strips a space back to structure may disturb suspect materials. Review the demolition scope before work begins rather than waiting for the later renovation filing.
Filings that may qualify for an exemption
Not every DOB application needs an ACP-5. Certain applications with no physical work, and qualifying work that does not disturb existing building materials, may be exempt from asbestos certification requirements. The filing label alone does not settle the question.
For alterations to buildings constructed after April 1, 1987, an asbestos certification exemption may be available. If known asbestos-containing material will be disturbed, it must still be handled and abated in accordance with applicable requirements.
Assuming a small alteration is exempt and then receiving a DOB objection can cost more time than resolving the question beforehand. When in doubt, ask before you file: a short scoping conversation can identify the assessment and documentation your project needs.
How the process works
Survey the proposed work area. A NYC DEP-certified asbestos investigator assesses the materials affected by the project and collects appropriate bulk samples of suspect materials.
Analyze the samples. An accredited laboratory tests the samples. Clear Advisory offers approximately 24-hour lab results.
Determine the filing route. If the affected area is free of asbestos, asbestos will not be disturbed, or the abatement scope qualifies as a minor project, the investigator completes, signs, seals, and submits the ACP-5 to DEP. DOB verifies the applicable documentation for the permit process.
Complete required abatement and filings. If the disturbance constitutes an asbestos project, the owner or authorized agent files an ACP-7 before abatement begins. Applicable ACP-20 or ACP-21 completion documentation follows the asbestos work. Full demolition generally still requires the entire-building ACP-5 certification described above.
Plan around the actual scope. Older buildings deserve particular attention, but age alone does not describe every project’s obligations. Confirm the materials, proposed disturbance, building history, and any available exemption before filing.
Why co-op and condo boards hear about this so often
Boards approve renovations every month, and managing agents routinely require a survey report and applicable asbestos documentation in the alteration package before work starts. This helps protect neighboring units, building staff, and the corporation from a stop-work order or a contamination event during the project.
Getting the assessment done at the alteration-package stage helps keep board approval, the DOB filing, and the contractor’s start date aligned.
