New York has two layers of asbestos rules. Industrial Code Rule 56, enforced by the NYS Department of Labor, covers the whole state, NYC included. Title 15 of the Rules of the City of New York, enforced by DEP, adds city-only forms and filings inside the five boroughs.
Inside the five boroughs
- ACP-5 before DOB permits, signed by a DEP-certified investigator.
- Asbestos project = more than 25 linear feet or 10 square feet: filed with DEP on an ACP-7 before work starts.
- ACP-21 completion form from DEP once the work passes.
- Variances and DOB ATRU review for complex projects.
Outside NYC
- An asbestos survey by a NYS-licensed inspector before renovation or demolition of most buildings built before 1974.
- No ACP forms. Your local building department decides what it needs for your permit.
- Projects over 160 square feet or 260 linear feet: a 10-day advance notification and fee to NYS DOL.
- 10 SF / 25 LF or less can use Rule 56 minor-project procedures.
What it means for your schedule
In the city, budget time for the ACP-5 before your permit and, if asbestos is found, for the ACP-7 filing before abatement. Outside the city, larger jobs need the 10-day NYS DOL notice. Either way, testing during design (not after demo starts) is the single best way to avoid delays.
Questions
Do NYC projects also follow Rule 56?
Yes. Rule 56 applies statewide, and DEP rules add to it within the city.
Is Long Island part of NYC rules?
No. Nassau and Suffolk follow NYS DOL Rule 56 and local building department requirements.
