Do I Need Permits for Residential Electrical Work in Calgary?

Short answer: yes, you need permits for almost anything with residential electrical work in Calgary beyond swapping a like-for-like fixture. The City says an electrical permit is required for all new wiring and for extensions or alterations to existing branch circuits. Replacing a light fixture on the same wiring usually doesn’t need one.

In Alberta, this isn’t optional. The Safety Codes Act requires a permit before you install, alter, repair, or add to an electrical system. Municipalities like Calgary issue the permits and do inspections; in places that aren’t accredited, provincial agencies handle it.

Who can pull the permit?

• Licensed electrical contractor working on your home (that’s us). Calgary’s rules say contractors must be qualified, hold the right license, and apply before starting work.

• Homeowner permits are allowed for your own principal residence if you’re doing the work yourself and can pass the inspections (rough-in and final). Calgary’s homeowner guide spells out the process.

If Crew Electrical Services is doing the work, we pull the permit, schedule inspections, and meet the inspector. You don’t have to play permit ping-pong.

Work that typically needs a permit (examples)

• Adding a new circuit or extending an existing one

• Installing an EV charger, hot tub, garage heater, or AC disconnect

• Panel work beyond simple breaker replacements, or any service upgrade

• Basement development wiring, kitchen rewires, outdoor outlets, and most exterior lighting

Those are all new wiring or alterations to existing circuits, which Calgary explicitly flags as permit-required.

What usually doesn’t need one

• Replacing a light fixture or a receptacle on the same wiring with a similar device

• Swapping a switch for a dimmer without changing wiring

If you’re not sure, assume it might need a permit until we confirm. The City’s rule of thumb is simple: new wiring or alterations need permits; like-for-like device swaps generally don’t.

What an inspection looks for

• Correct breaker and conductor sizing

• Proper GFCI/AFCI protection where required

• Grounding and bonding that meet current code

• Clean, accessible junctions and box fill

• Safe clearances at the panel and equipment

Homeowner permits require two inspections (rough and final). Contractor jobs follow a similar flow; we coordinate timing so you’re not juggling schedules.

Why permits protect you

• Safety: Catches load, protection, or grounding errors before they become “mystery trips” or hot connections

• Insurance and resale: Documented, inspected work avoids ugly surprises during claims or sales

• Future work: A clean permit trail tells the next contractor what’s behind your walls so projects move faster

Calgary specifics you should know

• Calgary requires electrical permits for all electrical installations in new builds or renovations, and permits must be in place before work begins. Contractors must be qualified and licensed.

• The City’s homeowner electrical wiring guide outlines inspections and scheduling and confirms that homeowner electrical permits get rough and final inspections.
