How Much Does It Cost to Add a Garage to Your Home?

Adding a garage will make your life easier and increase the value of your home. It will keep your car toasty warm in the winter, and the added storage space is a bonus that can’t be overlooked, especially if you have bikes, hockey nets, and any other outdoor activity sets really. Here’s a breakdown of the cost to build a garage:

But what does it cost to build a garage? It’s important to understand this kind of project’s costs before even deciding on your needs. Costs will vary depending on what you want to end up with: a single car garage, a double car garage, a garage with an apartment above it, a garage separate from your home, etc.

The Cost to Build a Garage:

Type of garage

Average cost (including materials and labour)

Single Car Garage (bare-bones) 12′ x 20′ $20,000$32,200
Single Car Garage (turnkey) 12′ x 20′ $27,000$41,400
Double Car Garage (bare-bones) 22′ x 20′ $35,000$57,500
Double Car Garage (turnkey) 22′ x 20′ $46,000$74,750

Note: these prices ranges are valid for both Greater Toronto & Greater Montreal

These prices are based on projects we’ve already completed, and they’ll vary depending on the kind of car garage you want.

The Cost of Adding a Single or Double Car Garage

The 2019 price for a turnkey single car garage – that is attached to your home – costs roughly $37,000, which is approximately between $120 and $175 per square foot. This includes insulation, electricity, plumbing and all necessary finishing. As for a “bare-bones” garage – basically a simple garage structure that doesn’t include any of the amenities mentioned above -, it’ll cost anywhere between $85 and $132 per square foot. When it comes to a turnkey double car garage, that’s likely to cost about $50,000. 

Simple & Double Garages

Adding a Garage with a Room Above it

When getting a garage added to their house, many homeowners decide to also get an extra room added above it. Adding more livable space to their home adds convenience and increases their house’s resale value. In fact, that’s exactly what the Dube family decided to do (see pictures below). The work was done by qualified 360° Verified Contractors. It allowed the family to add two extra bedrooms as well as a bathroom!

Cost of Adding a Carport

Adding a carport – as opposed to a garage – is much cheaper. However, keep in mind that it’s simply shelter for your car that’s comprised of a roof and no walls. Carports can vary in costs. Typically, we’ve seen some between $10,000 and $28,750, which is roughly between $40 and $50 per square foot

Will a Detached Garage Allow You to Save? 

A detached garage actually is cost-saving option as well as your home’s structural integrity doesn’t need to taken into consideration. However, there are many disadvantages to having a garage separate from your house. Firstly, your property needs to have enough space to add this separate & additional structure. Also, you’ll need to keep in mind that a detached garage cannot be converted into an extra room if ever your needs change and are looking for more livable space. Of course, you’ll need to go outside to access the garage, even in colder months! If you plan on using your garage as extra storage space, it’s usually more convenient when the space is attached to your home.

Other Costs to Consider: 

The costs mentioned above include labour and materials. However, other costs also need to be considered when planning such a project, like city permits, plans, etc. 

Costs of a building permit

Before you can begin building yourself a big beautiful garage, you need to first obtain the proper permits from the city or township. You’ll need to provide your certificate of location (from the purchase of your home) along with plans for your build.

Remember that most municipal rules require a specific amount of distance between your garage and your neighbour’s walls. Before you start, make sure you’ve checked to see what that distance is and that your plans adhere to it. The cost of a permit truly depends on your city and the borough you live in. 

Costs of Getting Plans done by an Architect or Technologist

An attached garage (whether it has a room above it or not) is considered an extension of your home. This means you’ll need plans from an architect or technologist. For a detached garage, you can buy prefabricated plans. Your best bet is to ask the municipality for the plans they require. If the city believes you’ll be fine with the plans being drawn up by a technologist, expect to pay between $1,500 and $2,000. However, if they believe you’ll need to plans to be drawn up by an architect, this can cost you anywhere between $2,000 to $5,000 – and maybe even more! Typically, the architect’s work will cost you about 10% of the total cost to build your garage. 

Once you have your plans in hand, you’ll be able to get your permits from the city. With the plans and permits in hand, you can then start getting quotes from 360° Verified Home Addition Contractors to find the right one for your project.

Costs for Siding and Windows & Doors

Some of our clients not only add a garage to their home, but take advantage of the opportunity to change their home’s overall look. If that’s the case for you, you’ll need to budget accordingly. The Gelinas family, for instance, converted their carport into a garage and also the decided to change their home’s siding and windows & doors since their home was going to be in a work site anyway. 

Changing your home’s siding typically costs anywhere between $4 and $40 per square food (labour and materials included) and will vary according to the siding material you’ve chosen. The cost of PVC double-paned windows is between $8,600 and $12,750 for a bungalow that has about 10 casement windows. A standard aluminum front door costs anywhere between $2,000 and $4,000.

The Cost of Tearing Down an Existing Garage

If you already have a garage, but want to tear it down and rebuild a new one, you’ll need to budget for $2,000 to $4,000 just for demolition. Demolition costs depend on many different factors, like the size of what you’re tearing down, the materials it’s made of, the kind of machinery used, how accessible your property is, if there are any hazardous materials to handle, etc. Costs also change when it comes to debris disposal. It’s important to get in touch with the city to get demolition permits as well. Also, be sure that you follow security protocols throughout the entire demolition phase.
