If you’re a plumber, contractor, or homeowner planning plumbing work in Massachusetts, you’ve likely encountered the Massachusetts Uniform Application for a Permit to Perform Plumbing Work. Navigating state regulations can feel overwhelming—but getting this right is essential to avoid fines, delays, or even work stoppages. In this guide, we’ll walk you through everything you need to know about this critical form, from where to find it to how to submit it correctly—so your project stays compliant and on schedule.
What Is the Massachusetts Uniform Application for a Permit to Perform Plumbing Work?
The Massachusetts Uniform Application for a Permit to Perform Plumbing Work is the standardized form required by the Board of State Examiners of Plumbers and Gas Fitters (part of the Massachusetts Division of Professional Licensure) for anyone seeking official permission to install, alter, or repair plumbing systems in the state.
This application ensures that all plumbing work meets the Massachusetts State Plumbing Code (248 CMR) and is performed by qualified individuals—either licensed plumbers or homeowners doing work on their own primary residence.
💡 Did You Know? According to the Massachusetts Division of Professional Licensure, over 12,000 plumbing permits are issued annually across the state—many delayed due to incomplete applications.
Who Needs to Submit This Application?
Not every plumbing task requires a permit—but most do. Here’s who typically needs to file the Massachusetts Uniform Application:
Licensed Master Plumbers – Required for commercial or residential projects beyond minor repairs.
Homeowners – Only if doing plumbing work on their primary residence (not rentals or second homes).
General Contractors – If they employ a licensed plumber or subcontract plumbing work.
Property Managers – When overseeing renovations that include plumbing changes.
⚠️ Important: Unlicensed individuals performing plumbing work on non-owner-occupied properties violate state law and risk penalties up to $1,000 per violation (per M.G.L. Chapter 142).

Step-by-Step Guide to Filling Out the Application
Follow these steps carefully to avoid common mistakes that cause processing delays:
Step 1: Identify the Permit Type
Check one of the following:
New Installation
Alteration
Repair
Replacement
Step 2: Provide Property Details
Include:
Full street address
County and city/town
Parcel ID (if known)
Step 3: Applicant Information
If you’re a licensed plumber: Enter your license number, name, and business details.
If you’re a homeowner: Check the “Owner-Builder” box and provide proof of ownership (e.g., property tax bill).
Step 4: Describe the Work
Be specific. Instead of “fix bathroom,” write:
“Replace 2-inch cast iron drain line under first-floor bathroom with PVC; install new P-trap and vent.”
Vague descriptions are the #1 reason for rejection.
Step 5: Attach Required Documents
You’ll typically need:
Two copies of plumbing plans (for jobs over $1,000 or involving new fixtures)
Proof of license (for professionals)
Owner affidavit (for homeowners)
Step 6: Pay the Fee
Fees vary by municipality but generally range from $50 to $200. Some towns accept online payments; others require checks.

Do not send it to the state board. Submit your completed application to your city or town’s Inspectional Services or Building Department. Processing usually takes 3–10 business days.

How Long Is the Permit Valid?
Once issued, your plumbing permit is valid for 6 months. If work hasn’t started within that time, the permit expires. You can request a one-time 90-day extension in writing—but don’t count on it.
After work begins, the permit remains active as long as inspections are scheduled within 180 days of the last approved inspection.
📊 Stat Insight: A 2025 study by the MA Municipal Association found that 32% of expired permits were due to missed inspection deadlines—not lack of progress.
Inspection Requirements After Permit Approval
Permits aren’t just paperwork—they trigger mandatory inspections:
Rough-in Inspection: After pipes are installed but before walls are closed.
Final Inspection: After all fixtures are installed and operational.
Schedule inspections through your local building department—usually online or by phone. Never conceal plumbing without approval; doing so can void insurance claims and lead to costly rework.
FAQs About the Massachusetts Plumbing Permit Application
Q1: Can I do my own plumbing as a homeowner in Massachusetts?
A: Yes—but only on your primary residence. You must still submit the Uniform Application and pass inspections. You cannot perform gas fitting work without a license.
Q2: Do I need a permit to replace a faucet or toilet?
A: Generally, no—if it’s a like-for-like replacement with no pipe modifications. But if you’re moving fixtures or altering drainage, a permit is required.
Q3: How much does the permit cost?
A: Fees are set locally. Expect $50–$150 for small residential jobs. Larger commercial projects may exceed $500.
Q4: Can I apply online?
A: It depends on your city. Boston, Worcester, and Cambridge offer online portals. Rural towns may require in-person or mail submissions. Check your municipality’s website.
Q5: What happens if I work without a permit?
A: You could face stop-work orders, fines up to $1,000, and be forced to open walls for inspection. Unpermitted work also complicates home sales.
Q6: Is the Uniform Application the same for gas fitting?
A: No. Gas work requires a separate application (Form G-1) and must be done by a licensed gas fitter—even homeowners cannot self-perform gas installations.
