NYC Licensed Master Plumber
NYC Plumbing & Gas Violation Code Library
Plain-language guides to the DOB, ECB/OATH, and gas violations we clear most often — what each one means, why it was issued, the penalties involved, and the exact steps a Licensed Master Plumber takes to resolve it and certify the correction with DOB.
Most plumbing and gas violations in NYC follow two enforcement tracks at once: a DOB violation that must be cleared with a Certificate of Correction, and an ECB/OATH summons that carries a dollar penalty. Each must be resolved separately. The guides below explain both tracks for the conditions we see most.
