NYC Plumbing Permit Expediting

A plumbing permit from the NYC Department of Buildings is required before performing most plumbing installations, alterations, repairs, or replacements. We work with licensed master plumbers to prepare and file DOB plumbing permits quickly and keep your project compliant.

What Is a Plumbing Permit?

A plumbing permit authorizes plumbing work on a building or property in New York City. DOB requires a permit to ensure work meets the NYC Plumbing Code and is performed by a licensed master plumber. Unpermitted plumbing work can result in violations, stop work orders, and failed inspections.

Plumbing Permit vs. LAA — Which Do You Need?

• Full plumbing permit: Required for most new installations, major alterations, and work tied to a construction or alteration job.
• LAA (Limited Alteration Application): Used for limited-scope plumbing repairs and replacements that qualify under DOB LAA rules without general construction.
• We review your scope of work and file the correct application to avoid delays and rejections.

When You Need a Plumbing Permit

• New plumbing fixtures, piping, or drainage systems
• Replacing or relocating water lines, gas lines, or sanitary lines
• Boiler, water heater, or oil burner installations
• Legalizing prior unpermitted plumbing work cited on a DOB violation
• Plumbing work required to clear a stop work order or pass inspection

Steps to Obtain a Plumbing Permit

• Define the scope: Identify whether the work requires a full plumbing permit or qualifies for an LAA filing.
• Hire a licensed master plumber: NYC requires plumbing work to be performed under a valid master plumber license.
• Prepare plans and documents: Submit drawings, specifications, and supporting forms required by DOB.
• File with DOB: Submit the application through DOB NOW or at the appropriate borough office and pay required fees.
• Plan review & approval: DOB reviews the filing for code compliance before issuing the permit.
• Inspections: Schedule rough-in and final plumbing inspections; approved work may require sign-off before a Certificate of Occupancy.
