Calgary Electricians · Residential & commercial · Calgary, Alberta
The City issued 35,712 electrical permits last year. Here is where that work happens, what it costs, which rules apply, and a straight way to get your job quoted.
Each shape is a Calgary community, lit by the electrical permits issued there 2023–2025. Hover to read one. The data →
Residential
Panels and service upgrades, EV chargers, basements, lighting, rewiring, generators and solar.
Commercial
Fit-outs, LED retrofits, switchgear, industrial power, EV charging, towers, data centres and standby power.
Circuit 01 · 15 A · Wire
Most electrical work in Calgary happens in buildings that already exist: basements, kitchens, suites and additions, each wired, inspected and closed in.
Read the guide
Circuit 02 · 200 A · Build
Every new house, row, tower and warehouse gets its own electrical permit, from the utility application to the final inspection before the power is turned on.
Read the guide
Circuit 03 · 40 A · Sun
Rooftop solar is the fastest-growing kind of electrical permit in the city, and most of it is retrofitted onto roofs that are already there.
Read the guide
Circuit 04 · 800 A · Power
Switchgear, transformers, feeders and the planned shutdowns that let a building change its electrical system without losing a day of business.
Read the guideElectricity reaches a Calgary building through equipment owned by three different parties. Knowing where one stops and the next starts tells you who to call, who pays, and which work needs a permit. Tap a symbol.
Transmission owners
High-voltage lines carry power across Alberta from generators to the substations around the city. Nothing on this side of the diagram is work for an electrician you hire; if you see a downed line of any kind, stay back and call 911.
Utility
Substations step transmission voltage down to distribution voltage and feed the lines that run along Calgary’s streets and lanes. Outages that start here are restored by the utility.
ENMAX Power
ENMAX Power owns and operates the distribution system inside Calgary: the overhead and underground feeders that reach every block. Your retailer sends the bill; ENMAX Power moves the electricity.
ENMAX Power
The pole-top or pad-mounted transformer steps the voltage down for the buildings it serves. When a service is added or enlarged, ENMAX invests a set amount toward the new load: for 2026 that is $3,168 per residential service1, and the customer pays the actual connection cost above it. Residential services of 400 A or larger must supply their own service cables1.
Utility meter · owner’s base
The revenue meter is the utility’s. The meter base it plugs into is part of the building’s service, and a homeowner permit cannot be used to install or alter it2. ENMAX does not charge to temporarily disconnect a site3; reconnecting afterwards is $166 an hour3, and a meter upgrade is $128 an hour for single phase3.
Owner · contractor permit
From the main breaker inward the equipment is the owner’s. Changing the main panel, the main breaker or the service needs a contractor’s permit2, priced at $112 plus $9.79 per $1,000 of job value plus the Safety Codes Council fee4.
Simplified single-line diagram for a typical Calgary service. Large commercial services, primary-metered sites and private substations draw the boundary differently. Fees and investment amounts are ENMAX Power’s 2026 approved schedule and the City’s 2026 permit fee schedule; see each source.
Electrical permits issued by the City of Calgary. The count has nearly doubled since 2019, and solar has gone from a sliver to thousands of permits a year.14

Most of an electrical quote is labour and material, and those are priced job by job. These are the parts that are published: the City’s permit fees and ENMAX Power’s approved charges.
Construction costs, not prices: Statistics Canada’s electrical-trade price index for Calgary residential buildings was 109.9 in Q2 2026 (2023 = 100), up 0.6% in a year5, against 2% for the 15-city composite5. Every cost guide →
Who may do the work, which permit it needs, which code applies and what happens when it is skipped. Each summary links to the source.
Alberta has used the 2024 Canadian Electrical Code, Part I, for work permitted since April 1, 2025. Existing installations that met the code of their day do not have to be upgraded just because the code changed.678
The electrical code in Alberta →In Calgary every new circuit and every extension or alteration of an existing one needs an electrical permit. Swapping a fixture on an existing box does not.2
Electrical permits in Calgary →Contractor electrical permits in Alberta go to Safety Codes Council master electricians. The public can check a tradesperson’s certificate in Alberta’s Tradesperson Lookup Tool.910
Hiring an electrician →You may wire the home you live in under a $116.50 homeowner permit, but not the service, main panel or meter base, solar, battery storage, EV-charger wiring or air conditioning.24
Homeowner permits →Request locates 3 to 5 full working days before digging for a garage feed or hot tub. In Alberta, 811 is Health Link, not a dig line: use Utility Safety Partners.1112
Click before you dig →Starting work before the permit is issued multiplies the City permit fee by 2, and a first offence under the Safety Codes Act can bring a fine of up to $100,000.413
Permits and penalties →Is 100 A enough? How far can the garage be before voltage drop matters? How long will the car take to charge? Every calculator shows its formula and its assumptions.
