How Much Does It Cost to Add a Garage to Your Home in 2024?


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. 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.

Consequences of COVID-19 on the construction and renovation sectors

*Many factors can influence the total cost of renovations, including, but not limited to, the type of work to be done, the area of the city, the type of building, the required labor, the needed materials, the protective measures, the length of the project (faster=higher cost) and contingencies.

Keep in mind that certain unforeseen events due to COVID-19 may affect the cost of renovation projects without notice. For example, the industry has come across a treated lumber shortage since the first lockdown, resulting in a massive fluctuation of prices. Other construction materials are likely to experience similar issues. For more details, read our article: Rising Lumber Prices: Another COVID-19 Effect?

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 $50,000, which is approximately between $200 and $350 per square foot. This includes insulation, electricity, plumbing and all necessary finishing. As for a “bare-bones” garage (a simple garage structure that doesn’t include any of the amenities mentioned above), the cost will be  anywhere between $240 and $290 per square foot. When it comes to a turnkey double car garage, that’s likely to cost about $120,000.

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 qualifed 53-point 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 $12,000 and $34,500, which is roughly between $90 and $120 per square foot.

Will a Detached Garage Allow You to Save?

A detached garage actually is cost-saving option. Your home’s structural integrity doesn’t need to taken into consideration when opting for a detached garage. 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 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.

Costs of a building permit

Before you can begin building yourself a 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 $1,800 and $2,500. However, if they believe you’ll need to plans to be drawn up by an architect, this can cost you anywhere between $2,500 to $6,000 — 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 53-point 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 $5 and $50 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 $10,300 and $15,300 for a bungalow that has about 10 casement windows. A standard aluminum front door costs anywhere between $2,500 and $5,000.

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.
