What's the best location to mount an EV charger in a Calgary detached garage?

Mount your EV charger on the wall nearest to your vehicle's charge port, at a height of 1.0 to 1.3 metres from the floor, on the side that allows the charging cable to reach the port without crossing a walkway or draping over the vehicle. For most EVs, the charge port is on the driver's side rear quarter panel (Tesla, Hyundai, Kia) or front left fender (Chevrolet), so the ideal mounting wall is typically the left wall when facing into the garage from the driveway.

In a detached Calgary garage, the mounting location also needs to account for the wire route from your house. Power comes from your main panel inside the house — typically in the basement — and runs to the detached garage either underground through conduit or overhead on a mast. The charger should be mounted near where the electrical feed enters the garage to minimize the length of internal wiring. If the underground conduit enters through the rear wall of the garage, mount the charger on or near that rear wall. If the feed comes overhead and enters through the ceiling or upper wall, the charger can be mounted on whichever wall is closest to both the feed entry point and the vehicle's charge port.

Height matters for both usability and Calgary's climate. Mounting at 1.0 to 1.3 metres puts the charger at a comfortable height for plugging and unplugging with winter gloves on — you do not want to bend down to floor level or reach up overhead when it is -30°C and you are wearing bulky gloves. The charging cable should hang in a gentle loop with the connector at roughly bumper height. Most chargers include a cable management hook or holster — mount this so the cable hangs neatly without touching the floor, where it can freeze into ice puddles tracked in on tires during winter.

Calgary's detached garages present specific considerations. Most detached garages in older communities like Inglewood, Ramsay, Hillhurst-Sunnyside, and Bridgeland are unheated and uninsulated. The charger unit must be rated for -30°C or colder — the Tesla Wall Connector, ChargePoint Home Flex, and Grizzl-E all meet this requirement. Mount the charger on an interior wall rather than an exterior wall if possible, as interior walls provide slightly more thermal buffering from extreme cold. Avoid mounting directly next to the garage door where cold air intrusion is greatest and where the charger is most exposed to wind-driven snow and rain when the door is open.

Moisture protection is critical in a detached garage. Calgary garages accumulate significant moisture from snow and ice melting off vehicles, spring rain, and condensation during chinook-driven temperature swings. Mount the charger high enough that it is above any potential water splash from vehicles, and ensure the electrical connections are sealed against moisture. If the garage floor drains poorly and standing water is an issue, consider mounting the charger higher (up to 1.5 metres) to keep it well clear of any water accumulation. Your electrician should install the circuit with appropriate weatherproofing at all junction points.

Proximity to the vehicle's charge port saves cable wear. The charging cable on most Level 2 chargers is 5 to 7.5 metres long. In a single-car detached garage, this is more than enough to reach from any wall-mounted position to the charge port. In a two-car garage, measure the distance from your preferred mounting location to the charge port with the vehicle parked in its normal position — you want the cable to reach comfortably without stretching taut, which stresses the cable and connectors over time. Leaving 1 to 2 metres of slack allows for easy handling.

Consider future needs. If you might add a second EV charger, mount the first one off-centre to leave room for a second unit on the same wall. If you are running underground conduit to the detached garage, have your electrician size the conduit to accommodate a second circuit in the future — pulling a second set of wires through existing conduit is far cheaper than trenching again. This forward-thinking approach is especially valuable given Calgary's frost depth requirements, which mandate conduit burial exceeding 1.2 metres.

Your licensed electrician will assess the specific layout of your detached garage and recommend the optimal mounting location based on the electrical feed entry point, your vehicle's charge port position, and the structural conditions of the garage walls.
