Manitoba Plumbing Permits and Inspection Requirements
Plumbing work in Manitoba is strictly regulated to ensure public health, safety, and environmental protection. All plumbing installations, alterations, repairs, or replacements—except minor maintenance (e.g., faucet washer replacement)—require a valid plumbing permit issued by the Manitoba Building Authority (MBA). Permits are mandatory for residential, commercial, and institutional projects, including new construction, renovations, and additions involving water supply, drainage, venting, or sewage systems. The Manitoba Building Code (MBC), which adopts the National Building Code of Canada (NBC) with provincial amendments, serves as the primary regulatory framework. Importantly, plumbing permits are separate from electrical or structural permits—even if work overlaps—and must be obtained before any plumbing activity begins.

Importantly, plumbing permits are separate from electrical or structural permits—even if work overlaps—and must be obtained before any plumbing activity begins.
Key Requirements
A plumbing permit is required for: installing or relocating fixtures (toilets, sinks, showers), altering water supply or drainage piping, connecting to municipal sewer or private septic systems, installing backflow prevention devices, and installing water heaters or hydronic heating systems. Only licensed Master or Journeyman Plumbers registered with the Manitoba Labour and Immigration’s Skilled Trades and Apprenticeship Branch may apply for and sign off on permits. Homeowners performing their own plumbing work must meet strict eligibility criteria—including proof of residency and completion of the MBA’s homeowner plumbing education module—and still require a permit. All work must comply with CSA B45.1 (plumbing fixtures), CSA B125.1 (valves), CSA B181 (drainage systems), and applicable sections of the MBC. Backflow prevention devices must be certified and tested annually by a certified tester.
Step-by-Step Process
1. **Determine Permit Need**: Confirm whether your project requires a permit using the MBA’s online Permit Determination Tool. 2. **Prepare Documentation**: Gather site plans (showing pipe routing, fixture locations, slope, venting), product specifications, soil test reports (for septic), and proof of plumber’s licence or homeowner eligibility. 3. **Submit Application**: Apply online via the MBA’s ePermit portal or in person at an MBA office. Include application form, plans, fees, and supporting documents. 4. **Review & Approval**: MBA reviews submissions within 5–10 business days; revisions may be requested. 5. **Commence Work**: Begin only after permit issuance and display the permit card visibly onsite. 6. **Schedule Inspections**: Request inspections through ePermit or phone (204-945-4663) for key stages: rough-in (before wall/ceiling enclosure), final (after fixture installation), and septic system installation (if applicable). Inspections must occur within 48 hours of request during business hours. 7. **Close Permit**: Upon passing final inspection, the permit is closed and a Certificate of Completion is issued.
Costs
Permit fees vary by project scope and building type. As of 2024, base fees range from $125 (minor residential alteration) to $1,200+ (large commercial projects). Fees include plan review, inspections, and administration. Additional charges apply for expedited review ($150) or re-inspection after failure ($75). Fee schedules are published annually in the MBA’s Fee Regulation (Man. Reg. 57/2023).
Common Mistakes
• Starting work before permit approval — results in stop-work orders and fines up to $10,000 under The Building Code Act. • Submitting incomplete or non-compliant plans — especially missing vent sizing, improper slope (must be ≥1% for drains), or unlabelled cleanouts. • Failing to schedule mandatory inspections — leading to concealed work violations and costly demolition for verification. • Using uncertified materials (e.g., non-CSA-approved PEX or fittings) or omitting required backflow preventers on irrigation or fire-sprinkler connections.

Do I need a permit to replace a water heater?
Yes. Replacing a water heater — whether tank-type or tankless — requires a plumbing permit because it involves connection to water supply, drainage, venting, and gas lines (if applicable). A licensed plumber must perform or supervise the work, and a final inspection is mandatory.
Can a homeowner obtain a plumbing permit without a licence?
Yes, but only if they meet all MBA homeowner eligibility requirements: occupying the dwelling as their principal residence, completing the free online Homeowner Plumbing Education Module, and submitting an affidavit. They cannot perform work on rental properties or for compensation.
What happens if my inspection fails?
You’ll receive a written deficiency notice. Correct the issues and request a re-inspection. A $75 fee applies for each re-inspection. Three consecutive failures may trigger a formal compliance review and referral to enforcement.
