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.

In recent years we have seen a huge jump in the demand for load shedding devices in Calgary. This is mainly driven by the City of Calgary Electrical inspections requiring load calculations on new installations of higher demand equipment. These are things like new air conditioning units, hot tubs, EV chargers and eclectic hot water tanks. Older houses usually have 60 – 100 amp services and weren’t designed to handle the type of electrical equipment we are installing today.

If you are planning on adding any of these larger loads to your house, you most likely have heard about load shedding devices. A few years ago these were not that common, but now we are seeing them everywhere

What a Load Shedding Device Actually Is (In Plain English)

A load shedding device is a large switch installed near your panel. It is connected to a selected high demand load like an EV charger or an air conditioner. It is also connected to the incoming service wires to your house with a device called a current transformer th at monitors the current moving through the wires. When the demand gets too high, like if the homeowner is cooking, using the dryer and has a lot lighting loads on, the load shedding device turns off the connected  load until a later time when the demand isn’t so high.

You don’t know this is happening, but your EV charger may end up charging in the middle of the night. It just manages things so you don’t overload your panel.

Why Calgary Inspectors Are Requiring These More Often

When we are installing larger equipment, like the EV charger, air conditioner, hot tub or electric heat, the City of Calgary inspectors are now asking us to complete a load calculation on your home. Its not optional, and it needs to be submitted to close the permit

With most 100 amp services, the load calculation comes back tight. When that happens, the inspector wants to see 1 of 2 things.

1. We can upgrade to a 200 amp service. This usually involves replacing the service conductors, digging up the yard, replacing the meterbase, and replacing the panel. Depending on the complexity, this can run well beyond $7500.00. This isn’t even including the fees from Enmax or Fortis, and thats only if your areas transformer can handle it.
2. We can also install a load shedding device. This is a code compliant way of passing an electrical inspection.

Most people choose the load shedding device because it’s cheaper, quicker, and doesn’t require tearing up the yard or dealing with the utility like Enmax or Fortis.

When You’re Likely Going to Need One

Here’s what we are seeing constantly in Calgary:

• • • EV chargers on 100A service, almost always need a load shedding device
    • A/C installs on older homes most likely need a load shedding device.
    • Hot tubs, almost certain a load shedding device will need to be installed
    • Basement developments with extra heat load depends, but trending upward

If the calculation shows you’re fine, we won’t recommend one. But if you’re close to the limit, it’s better to address it up front than have the inspector fail the job later.

How It Works Day to Day

The device is a box that sits connected to your panel. It is constantly monitoring how much power your home is drawing. If it gets close to the service maximum, it switches off the EV charger or air conditioner. When the household demand drops, usually when its not so busy, the load gets turned back on.

What It Costs in Calgary

Right now, to install a  load shedding device properly with the load calculation, programming, wiring, and permit runs about $1,900- $2,200. Prices vary depending on the house, type of load shedding device and what we’re tying into, but that’s a typical number.

Compare this to a full service upgrade (which can hit $6,000–$8,500+), it’s a great solution.

Why This Matters for Homeowners

The invisible issue is that Calgary homes are getting pushed harder electrically than they were designed for. And the city is noticing.

A load shedding device:

• Keeps your existing electrical service safe
• Gets your new equipment passed on inspection
• Saves you from a major service upgrade
• Lets you run EV chargers, air conditioners and hot tubs together without overloading the panel

We’re installing these constantly now and they always are always a big surprise at the end of a project when the air conditioner or new hot tub fails inspection and load calculation.

Final Thoughts

If you’re thinking about adding an EV charger or anything with a big electrical load, it’s worth getting a load calculation done before you book the install. It’s the easiest way to avoid surprises from the inspector. And if you do need a load shedding device, at least you’ll know ahead of time.

Crew Electrical Services handles the load calculations, permits, and installation across Calgary. If you have questions or want to know whether your home needs one of these devices, feel free to reach out. We are happy to take a look and point you in the right direction.

Power in Calgary is usually steady. It only takes one event to damage a furnace board, a fridge, a TV, or a charger. Whole home surge protection cuts that risk. Think of it as a safety net for everything that plugs in or ties into your electrical system.

Crew Electrical Services installs surge protection that fits your panel, your loads, and your plans. We keep the scope simple, the routing clean, and the labeling clear. You get a solution that works quietly in the background.

What Whole Home Surge Protection Actually Does

A surge is a short spike in voltage. It can come from utility switching, nearby lightning, a motor starting, or a fault. Sensitive boards do not like spikes. A whole home surge protective device sits at the service and diverts excess energy to ground. The result is fewer failures and fewer mysterious “it just died” moments.

This is not the same as a power bar. Strip protectors live at one outlet. A service-level device covers the entire home. It also protects circuits that do not use receptacles, like hard-wired appliances and HVAC equipment.

Where We Install It and How It Looks

Most Calgary homes get surge protection at the main panel. Sometimes we add a device at a subpanel that feeds a garage, a suite, or a shop. Placement depends on your layout and where sensitive gear lives.

What you will see:

• A compact rated device mounted next to the panel

• Short, tidy leads landed on dedicated spaces as required

• Clear labeling on the panel legend so future service is easy

No mess. No guesswork. It should look like it belongs.

What It Protects Day to Day

• Furnaces and air handlers

• AC condensers and heat pumps

• Fridges, freezers, ranges, and dishwashers

• Washers and dryers

• TVs, media gear, and gaming systems

• Office equipment and network gear

• EV chargers and smart home devices

Many of these have control boards. Boards are the first to go during a surge. Prevention is cheaper than board replacement and downtime.

Do You Still Need Point-of-Use Protection

A layered approach is best. Whole home protection handles the heavy lifting. Point-of-use protection adds a second layer for the most sensitive gear. We help you pick where to add strips or in-wall protectors. You do not have to put them everywhere.

How Crew Electrical Services Designs Your Setup

We start with a quick look at your panel and service. Then our team places a device that matches your service rating and available spaces. We keep conductors short for performance, land bonds correctly, and label everything so the next electrician understands the layout.

You will know:

• The device rating and where it sits

• Which panel or subpanel it protects

• How to read the status indicator at a glance

What Happens During Installation

Most installs take a single visit. Power is off for a short window while we land the device safely. We protect floors, route neatly, and seal any exterior penetrations if the meter area is involved. After we restore power, we verify status lights and walk you through what normal looks like.

Common Questions We Hear

Will a surge protector stop every event?
No single device stops everything, but a properly sized, properly installed whole home device handles most daily and seasonal spikes. For very sensitive gear, we add point-of-use protection.

Is this only for lightning?
Lightning is rare. Utility switching, motors starting, and neighborhood work can still cause spikes. Those are the events that quietly shorten the life of boards.

Will this help with flicker?
Flicker often points to load or connection issues, not surges. We can check for loose neutrals, shared circuits, and panel capacity while we are on site.

Do I need a panel upgrade first?
Not always. If your panel has space and the service is in good shape, we can install a device on the existing system. If space or capacity is tight, we will show options.

How will I know it is still working?
Most devices have a visual indicator. We show you how to check it. If you want extra peace of mind, we can include it in a yearly electrical check.

Why Whole Home Surge Protection Is Smart in Calgary

Weather swings, utility work, and modern homes full of electronics create real exposure. A simple device at the service reduces risk across the board. It protects your HVAC during heat waves and cold snaps. It protects your kitchen and laundry gear. It protects chargers and smart devices that are always connected.

This is not a flashy upgrade. It is a quiet one that pays for itself when nothing fails.
