Connecticut asbestos regulations.
Who licenses asbestos work in Connecticut, who takes the notification, and how long before the job you have to file. Plus how the federal rules layer on top.
State licensing & accreditation
Asbestos abatement work in Connecticut is licensed/accredited through the Connecticut Dept. of Public Health (DPH), Asbestos Program under RCSA Sec. 20-440 et seq.; CGS Sec. 19a-88, 19a-89.
Credentials the state issues:

Connecticut Dept. of Public Health (DPH), Asbestos Program — asbestos licensing.
Notification
Notifications go to the Connecticut Dept. of Public Health (DPH), Asbestos Program under RCSA Sec. 19a-332a (Standards for Asbestos Abatement).
- Advance notice: 10 days before abatement begins.
- Notification details / form.
How the federal rules layer in
No matter the state, federal OSHA 29 CFR 1926.1101 (asbestos in construction), EPA NESHAP (40 CFR 61, Subpart M), and AHERA worker accreditation still apply. A state program layers its own licensing and notification on top of — not instead of — these. Where Connecticut has no state license, the federal accreditation and NESHAP notification requirements are the floor.
Connecticut-specific notes
- Licensing and notification both run through DPH, not the environmental agency.
- All demolitions require notification regardless of asbestos presence.
- Renovation thresholds: 160 sq ft / 260 linear ft / 35 cu ft.
- DEEP separately regulates asbestos waste.
