Last month, we spoke at length about “Planning A Home Addition”, while in November, we touched on the cost of a home extension in Calgary.
In today’s blog, we’re going to combine these topics to take a look at the cost of a home addition in Calgary. This guide will provide you with information on what can impact the costs and the average price in YYC.
But firstly…
What’s The Difference Between Calgary Extensions & Additions?
It’s important to know that while extensions and additions are similar, they are in fact, quite different.
Extensions refer to “extending the existing property” and basically means making specific parts of the home larger.
Additions, on the other hand, refer to adding floor areas to your home, whether as a second storey or an adjacent room that goes over your yard space. But in many cases, it’s the former not the latter.
In simple terms, additions means building upwards, and extensions refer to building outwards.
The Cost Breakdowns of a Home Addition in Calgary
Adding a home addition in Calgary is a significant investment because of the amount of work required. We take a look at some of the key factors that can impact the final cost:
Building structure – you might require extra foundation work to ensure that your house can hold up a second storey. This might mean additional depth to your walls and roof for the addition.
The type of renovations required – the design, layout and architectural structure of the addition, plus the additional need for plumbing, electrical and HVAC systems will impact the final cost. For example, a kitchen renovation will require two of the three systems above, while a simple bedroom only one. Thereby, the kitchen will cost more than a bedroom.

Interior and exterior elements – you’ll have to consider shingles, siding, insulation, windows, and flooring as part of the home addition. Specific materials (such as siding) will be impacted by the quality that you choose.
The labour hire – let’s face it, you won’t be building the addition yourself. You’re going to need a Calgary renovation company to handle it for you. That means paying for their labour, which will be determined by their experience, quality of work and the size and timeframe of the project.
Average Cost of a Calgary Home Addition
Having a rough idea on the estime can prepare you for your project. We have some figures for you below:
- HomeGuide states that “the average house addition costs $86 to $208 per square foot, with most homeowners spending between $22,500 and $74,000 per room, depending on the quality of renovations”
- Home Advisor offers similar figures, suggesting that “the average cost to build an addition or add a room to your home is $46,258. Most homeowners report spending between $20,724 and $71,804.
Remember that depending on what you choose for your property, from the material quality to the renovation themselves, will all impact the final cost of the home addition. Get the calculator out and start planning!
