Do I need a permit to move a toilet or sink location during a bathroom reno in Metro Vancouver?

Yes, moving a toilet or sink to a new location during a bathroom renovation requires a plumbing permit in every Metro Vancouver municipality. Any time you relocate a fixture that requires new drain or supply rough-in — even shifting a toilet a few feet — you are modifying the plumbing system, which triggers permit requirements under the BC Building Code and the BC Plumbing Code.

When you move a toilet, the drain line must be extended or rerouted to the new location, and the vent stack connection may need to be adjusted to maintain proper drainage and prevent sewer gas from entering the home. Toilet drains are typically 3-inch ABS pipe with a specific slope requirement (1/4 inch per foot minimum), and relocating them often means cutting into the subfloor or concrete slab. In homes with a concrete slab-on-grade foundation — common in many Vancouver-area ranchers and ground-level condos — moving a toilet drain involves cutting and breaking concrete, which adds $1,500–$4,000 or more to the project depending on the distance moved and whether the slab needs structural repair afterward.

Moving a sink is generally less invasive than moving a toilet because sink drains are smaller (1-1/2 inch) and supply lines are easier to extend, but it still requires a plumbing permit. The new drain location must connect to the existing vent system, and the supply lines (hot and cold) must be extended to the new position. A typical sink relocation in Metro Vancouver costs $800–$2,500 for the plumbing work alone, depending on how far the fixture moves and whether the existing wall cavity provides a clear path for new piping.

The permit process in Metro Vancouver is straightforward but varies slightly by municipality. In the City of Vancouver, you apply for a plumbing permit through the Development, Buildings and Licensing department — fees typically run $150–$400 for a residential bathroom plumbing permit. Burnaby, Surrey, Richmond, and other Metro Vancouver municipalities have similar processes through their building departments. The permit triggers one or two inspections: a rough-in inspection before walls are closed up (to verify pipe sizing, slope, venting, and connections) and a final inspection after fixtures are installed.

All plumbing rough-in work must be performed by a licensed plumber in British Columbia. This is not optional — it is a legal requirement, and no municipality will issue a plumbing permit to an unlicensed individual for residential rough-in work. The licensed plumber will typically handle the permit application as part of the project.

For condo and strata bathroom renovations, moving fixtures adds another layer of complexity. You need written strata council approval before any plumbing modifications, and most strata corporations require proof that a licensed plumber is performing the work, along with evidence of contractor insurance (typically $2 million minimum liability) and WorkSafeBC clearance. Moving a toilet in a concrete-slab condo may also require an engineering assessment to confirm that cutting into the slab will not compromise structural integrity or waterproofing of the unit below.

Skipping the permit is never worth the risk. Unpermitted plumbing work creates liability issues, complicates insurance claims if water damage occurs, and will be flagged during a home inspection when you sell. The permit fee of $150–$400 is trivial compared to the $15,000–$40,000 cost of a typical Metro Vancouver bathroom renovation — and it ensures the work is done to code and inspected by a qualified professional.
