How much does commercial electrical rough-in cost per square foot in Calgary?

Commercial electrical rough-in in Calgary typically costs $8 to $25 per square foot, with the wide range reflecting the enormous variation between a basic office shell and a high-demand space like a commercial kitchen or medical facility. A straightforward office or retail space with standard lighting, outlets every 3.6 metres along walls, and basic data rough-in usually falls in the $8 to $14 per square foot range. More complex spaces — restaurants, dental clinics, hair salons, manufacturing bays — push into the $15 to $25+ range due to higher circuit density, specialized equipment circuits, three-phase power distribution, and additional code requirements.

The rough-in phase covers everything that goes behind walls and above ceilings before drywall and finishing: running NMD90 and AC90 cable through studs and joists, installing electrical boxes for outlets, switches, and fixtures, pulling wire for dedicated equipment circuits, roughing in panel locations and sub-panels, and setting up conduit runs for data and communication cabling. In Calgary's commercial market, AC90 armoured cable is standard for most exposed and accessible runs, which adds material cost compared to residential NMD90 wiring. Your electrician will work from an electrical plan that specifies circuit layouts, panel schedules, and load calculations — for commercial spaces, this plan often needs to be stamped by a professional engineer, adding $1,500 to $5,000 in design costs before the first wire is pulled.

Calgary's climate adds specific considerations to commercial rough-in work. If the space involves exterior wall penetrations, conduit runs through unheated areas, or connections to rooftop HVAC equipment, your electrician must account for Calgary's extreme temperature swings. Chinook-driven thermal cycling causes expansion and contraction in metal conduit, so proper expansion fittings and flexible connections are essential for long horizontal conduit runs. For spaces in older Calgary commercial buildings — particularly along the downtown core, Inglewood, Kensington, and 17th Avenue — existing electrical infrastructure may need significant upgrades before rough-in can proceed, potentially adding $3,000 to $10,000 for panel upgrades or service entrance work.

All commercial electrical rough-in in Calgary requires an electrical permit from the City of Calgary (or the applicable municipality for surrounding communities). Your electrician applies for the permit before starting work, and a Safety Codes Officer inspects the rough-in before walls are closed. Permit costs for commercial projects typically range from $150 to $500+ depending on the scope. Never allow walls to be closed before the rough-in inspection passes — opening finished walls for an inspector to verify wiring adds thousands in unnecessary cost. Make sure your electrician carries current WCB Alberta coverage and adequate commercial liability insurance before they begin work on your space.

For a reliable estimate, have at least two licensed commercial electricians walk your space with your architectural plans. The per-square-foot cost depends heavily on your specific layout, equipment requirements, and the condition of existing electrical infrastructure.
