Illegal / Unlicensed Plumbing Work in NYC
A DOB violation and ECB/OATH summons arising when plumbing work was performed by someone other than — or not supervised by — a Licensed Master Plumber.
What It Means
NYC requires DOB plumbing permits to be pulled and the work supervised by a Licensed Master Plumber. Using an unlicensed contractor creates additional violations and does not clear the original issue. This is a frequent reason a prior “fix” never cleared a violation. These conditions commonly pair with a work-without-permit charge under §28-105.1.
Why You Got It
Common triggers: the owner hired a handyman or general contractor without a Licensed Master Plumber; the work is discovered at inspection or during a sale.
Consequences & Penalties
Stacked penalties typically apply — a work-without-permit penalty plus penalties for the underlying condition, all set by the DOB penalty schedule and varying by infraction code. Prior unlicensed work usually must be redone or verified by a Licensed Master Plumber.

How to Clear It
- A Licensed Master Plumber inspects the prior work and documents deficiencies.
- File the proper permit and correct the work to code under LMP supervision.
- Pass inspection, pay or waive penalties, and submit the Certificate of Correction.

Frequently Asked Questions
A handyman did my plumbing and now I have a violation — can it be fixed?
Yes. A Licensed Master Plumber inspects the prior work, files the proper permit, corrects it to current code, passes inspection, and certifies the correction. Work done by an unlicensed person typically has to be redone or verified by an LMP.
Do I really need a licensed plumber to remove the violation?
Yes. For DOB plumbing permits and the work required to clear the violation, NYC law requires a Licensed Master Plumber to file and supervise. Using an unlicensed contractor creates additional violations and does not clear the original issue.
How much will this cost in penalties?
Penalties stack — a work-without-permit penalty plus penalties for the underlying condition — and the exact amounts are set by the DOB penalty schedule, which varies by infraction code. Confirm against your summons.
