New Brunswick Plumbing Permits and Inspection Requirements
In New Brunswick, plumbing work—whether for new construction, renovations, or repairs—must comply with the New Brunswick Building Code (NBC), which adopts the National Building Code of Canada (2015 edition) with provincial amendments. Plumbing permits and inspections are mandatory to ensure public health, safety, and water system integrity. The Technical and Skills Development Act empowers the Department of Post-Secondary Education, Training and Labour to regulate trades—including plumbing—while the Electrical Installation and Inspection Act (though primarily electrical) underscores the integrated oversight of building systems. All plumbing installations must be performed by licensed plumbers or under direct supervision of a licensed professional, unless exempted (e.g., minor repairs like faucet washer replacement). Permits are administered locally through municipal building departments or, in unincorporated areas, via Service New Brunswick (SNB) regional offices.

In New Brunswick, plumbing work—whether for new construction, renovations, or repairs—must comply with the New Brunswick Building Code (NBC), which adopts the National Building Code of Canada (2015 edition) with provincial amendments. Plumbing permits and inspections are mandatory to ensure public health, safety, and water system integrity. The Technical and Skills Development Act empowers the Department of Post-Secondary Education, Training and Labour to regulate trades—including plumbing—while the Electrical Installation and Inspection Act (though primarily electrical) underscores the integrated oversight of building systems. All plumbing installations must be performed by licensed plumbers or under direct supervision of a licensed professional, unless exempted (e.g., minor repairs like faucet washer replacement). Permits are administered locally through municipal building departments or, in unincorporated areas, via Service New Brunswick (SNB) regional offices.
Key Requirements
A plumbing permit is required for: installing, altering, extending, or replacing any water supply, drainage, venting, or sewage disposal system—including septic systems, backflow preventers, water heaters, and greywater systems. Exemptions are narrow and do not include fixture replacements involving pipe modifications. Licensed plumbers must hold valid certification issued under the Technical and Skills Development Act and be registered with the New Brunswick Apprenticeship and Occupational Certification Board. Plans submitted with applications must include detailed schematics, pipe sizing calculations, material specifications, and compliance statements referencing NBC Chapter 7 (Plumbing) and CSA B48 standards. Septic system designs require separate approval from the Department of Environment and Local Government.
Step-by-Step Process
1. **Determine Jurisdiction**: Confirm whether your project falls under municipal authority (e.g., City of Saint John, City of Moncton) or provincial oversight (rural/unincorporated zones). 2. **Prepare Documentation**: Complete the official Plumbing Permit Application (Form NB-PLUMB-01), attach stamped plans, proof of plumber’s license, and site-specific details (lot/block, legal description). 3. **Submit & Pay**: File online via SNB’s ePermit portal or in person at a designated office. Processing typically takes 5–10 business days. 4. **Schedule Inspections**: Required inspections include: rough-in (after piping installed but before concealment), final (post-fixtures and testing), and septic system installation (if applicable). Notify your local inspector at least 48 hours in advance. 5. **Obtain Certificate of Compliance**: Upon passing all inspections, the issuing authority provides a signed certificate—required for occupancy or utility connection.
Costs
Permit fees vary by municipality and project scope. As of 2024, base fees range from $120 (minor alterations) to $650+ (full residential re-plumb or commercial projects). Septic system permits incur additional fees ($300–$900) and may require third-party engineering review. Municipalities may charge inspection re-test fees ($75–$150) for failed inspections. Fee schedules are published annually on municipal websites and SNB’s Construction Licensing page.
Common Mistakes
Applicants frequently omit required documentation—especially signed plans or plumber license verification—causing delays. Installing non-compliant materials (e.g., non-CSA-certified fittings or undersized vent pipes) leads to failed inspections. Another frequent error is scheduling inspections before all required components (e.g., pressure tests, trap primers, backflow device commissioning) are completed and documented. Finally, performing regulated plumbing work without a licensed plumber—even on private property—violates the Technical and Skills Development Act and may void insurance coverage or future sale disclosures.

Do I need a permit to replace a water heater?
Yes. Replacing a water heater requires a plumbing permit because it involves connecting to potable water, drainage, and often gas or electrical systems. A licensed plumber must perform or supervise the installation, and both rough-in and final inspections are required.
Can I do my own plumbing work as a homeowner?
Only limited exemptions apply—such as replacing washers or repairing leaks without altering piping. Any work involving new connections, pipe extensions, fixture relocation, or septic systems requires a licensed plumber and a valid permit. Self-performed non-exempt work is illegal and may result in enforcement orders or fines.
What happens if I start plumbing work without a permit?
Work done without an approved permit is considered non-compliant. You may be ordered to halt work, expose concealed piping for inspection, or even拆除 and redo installations. Fines up to $10,000 per offence may apply under the Technical and Skills Development Act, and failure to obtain a Certificate of Compliance can delay property transfers or insurance claims.
