Do I need a permit to add heated flooring in a bathroom in the City of Vancouver?

Yes, installing electric radiant heated flooring in a bathroom in the City of Vancouver requires an electrical permit. The heating element is an electrical device that must be wired to a dedicated circuit with a GFCI-protected breaker, and all electrical work in BC requires a permit and inspection by Technical Safety BC (TSBC).

Electric in-floor radiant heating is one of the most popular upgrades in Metro Vancouver bathroom renovations, and for good reason — stepping onto a warm tile floor on a damp November morning is a genuine luxury. The systems use thin electric heating cables or mats embedded in thin-set mortar beneath the tile. They are energy-efficient for the small area of a bathroom floor and operate on standard 120-volt or 240-volt circuits depending on the floor area.

The permit requirement is triggered by the electrical work, not the heating mat itself. A licensed electrician must install a dedicated circuit from the electrical panel to the bathroom, install a GFCI-protected breaker (required by the Canadian Electrical Code for in-floor heating systems), and connect the heating cable or mat to a thermostat/controller mounted on the bathroom wall. The electrician files a Declaration of Work with TSBC, and an inspection is scheduled to verify the installation meets code before the floor is tiled over. This is critical — once tile is laid over the heating system, it cannot be inspected without destructive removal, so the inspection must happen before the tile goes down.

If the heated floor installation is part of a larger bathroom renovation that also involves plumbing changes or structural modifications, you will need a building permit and possibly a plumbing permit in addition to the electrical permit. If you are simply adding heated flooring to an existing bathroom without moving any plumbing or modifying the structure, the electrical permit is typically the only permit required.

Cost breakdown for heated bathroom flooring in Metro Vancouver:

• Heating mat or cable system: $10–$20 per square foot for quality brands (Nuheat, Schluter Ditra-Heat, SunTouch). A typical 40-square-foot bathroom floor runs $400–$800 for the heating element
• Thermostat/controller: $150–$350 for a programmable thermostat with floor sensor
• Electrical installation: $400–$800 for the dedicated circuit, GFCI breaker, and thermostat wiring
• Electrical permit and TSBC inspection: $100–$250
• Total installed cost: $1,500–$4,000 depending on bathroom size, system selected, and electrical panel accessibility

The heating mat installation itself — laying the mat in thin-set on the subfloor — is sometimes done by the tile installer rather than the electrician. However, all electrical connections (wiring the mat to the thermostat and the thermostat to the panel) must be done by the licensed electrician. Some homeowners purchase the heating mat and lay it themselves to save on labour, then have the electrician make all electrical connections. This is acceptable as long as the electrical work is professionally done and inspected.

Important considerations for Metro Vancouver installations: ensure your electrical panel has capacity for the additional circuit (older homes in East Vancouver, Kitsilano, and other established neighbourhoods may have panels at or near capacity). The Schluter Ditra-Heat system is particularly popular in Metro Vancouver because it combines a waterproofing membrane with the heating element — an efficient two-in-one solution that addresses both heated flooring and the critical waterproofing needs of Vancouver's humid climate. Whichever system you choose, confirm that your tile installer has experience working over in-floor heating systems, as the thin-set application and tile installation technique differs slightly from standard floor tile work.
