If you’re renovating a bathroom, installing new pipes, or completing any plumbing work in New York City, you’ll eventually need official approval from the Department of Buildings (DOB). The DOB NOW Inspections: How to Request for Plumbing Sign Off process can feel overwhelming—especially if you’re navigating it for the first time. But don’t worry: this guide breaks it down into simple, actionable steps so you can get your plumbing project legally cleared without delays or fines.
What Is a Plumbing Sign-Off in NYC?
A plumbing sign-off is the final approval from the NYC Department of Buildings confirming that your plumbing work complies with local codes and safety standards. Without it, your project remains incomplete in the city’s eyes—and you risk penalties, failed resale inspections, or even water shutoffs.
According to the NYC DOB, over 30% of plumbing permits in residential buildings face delays due to incomplete or incorrect sign-off requests. Getting it right the first time saves both time and money.
💡 Pro Tip: A plumbing sign-off is required for any work involving water supply, drainage, gas piping, or sewer connections—even minor upgrades.
When Do You Need a Plumbing Inspection?
Not all plumbing work needs a DOB inspection—but most does. Here’s a quick reference:
| Work Type | Inspection Required? |
|---|---|
| New water heater installation | ✅ Yes |
| Replacing a faucet or showerhead | ❌ No |
| Relocating a toilet or sink | ✅ Yes |
| Installing a new gas line | ✅ Yes |
| Fixing a leaky pipe (same location) | ❌ No |
If your project required a plumbing permit (which you’d file via DOB NOW: Build), then you must schedule an inspection for sign-off.
For more on NYC plumbing codes, refer to the International Plumbing Code (IPC), which NYC adopts with local amendments.
Step-by-Step: How to Request a Plumbing Sign-Off via DOB NOW Inspections
Follow these 5 precise steps to request your plumbing inspection through the official DOB NOW portal:
Step 1: Confirm Permit Approval & Work Completion
Before requesting an inspection:
- Your plumbing permit must be approved and active in DOB NOW: Build.
- All work must be 100% complete and accessible for inspection (e.g., no drywall covering pipes).
- Required third-party inspections (like for gas piping) must already be passed, if applicable.
Step 2: Log In to DOB NOW: Inspections
Go to https://a810-bisweb.nyc.gov/bisweb/ and log in with your DOB NOW account (the same one used for permit filing).
🔐 Security Note: Only the permit holder (owner or licensed contractor) can request inspections.
Step 3: Select “Request Inspection”
- Navigate to “Inspections” > “Request Inspection.”
- Enter your job number (found on your permit).
- Choose “Plumbing” as the inspection type.
- Select available dates (typically within 2–5 business days).
Step 4: Submit Required Documents (If Prompted)
Some plumbing inspections require:
- Photos of pipe installations
- Pressure test results (e.g., 50 psi for water lines held for 15 minutes)
- Gas piping certificates (from a Licensed Master Plumber)
Upload these directly in the portal before submitting.
Step 5: Prepare for the Inspector’s Visit
On inspection day:
- Ensure clear access to all plumbing fixtures and pipes.
- Have your approved plans and permit on-site.
- A licensed plumber or permit holder must be present.
If the inspector approves, you’ll receive an “Inspection Passed” status in DOB NOW within 24–48 hours—your official sign-off.
⏱️ Average Wait Time: Most plumbing inspections are scheduled within 3 business days of request, per NYC DOB 2025 performance data.
Common Reasons for Plumbing Inspection Failures
Even experienced contractors get tripped up. Here are the top 3 reasons plumbing inspections fail in NYC:
- Improper Venting – Every drain must connect to a vent to prevent sewer gas buildup.
- Missing Shut-Off Valves – Required within 3 feet of every plumbing fixture.
- Unapproved Materials – Using non-Code-compliant pipes or fittings (e.g., non-listed PEX).
📊 According to a 2024 NYC DOB audit, 42% of failed plumbing inspections were due to venting errors—often overlooked in DIY projects.
DOB NOW vs. Old Paper Process: What’s Better?
The city phased out paper inspections in 2020. Here’s why DOB NOW is superior:
| Feature | DOB NOW Inspections | Old Paper System |
|---|---|---|
| Scheduling Speed | 2–5 days | 2–3 weeks |
| Real-Time Status | ✅ Yes | ❌ No |
| Document Upload | Digital | In-person only |
| Rescheduling | Online, instant | Phone/waitlist |
Verdict: DOB NOW is faster, transparent, and mobile-friendly—ideal for today’s contractors and homeowners.
What If Your Inspection Fails?
Don’t panic. You can:
- Review the inspector’s comments in DOB NOW.
- Fix the issues (usually within 10 days).
- Reschedule a re-inspection (same portal, no extra fee for first re-inspection).
⚠️ After two failed attempts, your permit may be suspended—so get it right the second time.

There’s no separate fee for the inspection—it’s included in your original permit cost. However, re-inspections after two failures may incur penalties.
Q3: Who can be present during the inspection?
