Estimated Value Added by Garage Type
The value a garage adds depends on its size, whether it is attached or detached, and what is standard in your neighbourhood. Here are typical ranges for the GTA market.
Single Attached Garage
$20K - $50KThe most common garage configuration in older GTA neighbourhoods. Provides covered parking for one vehicle plus some storage space. Valued for convenience and direct home access.
Double Attached Garage
$40K - $80KThe standard in most newer GTA subdivisions. Two-car families consider this essential, not a bonus. In suburbs like Churchill Meadows and Meadowvale, nearly every home has one.
Single Detached Garage
$15K - $35KCommon in older neighbourhoods like Streetsville, Clarkson, and parts of Etobicoke. Less convenient than attached but still provides covered parking and storage. Often accessed via a rear laneway.
Triple Attached Garage
$60K - $120KFound in higher-end properties and custom builds. Appeals to buyers with multiple vehicles, recreational equipment, or who want dedicated workshop space. Most common in premium Oakville and Lorne Park homes.
Why GTA Buyers Value Garages
A garage is more than just a place to park a car. In the Ontario market, buyers see garages as multi-functional spaces that serve several important purposes.
Winter Weather Protection
Ontario winters mean snow, ice, and freezing temperatures. An attached garage eliminates morning scraping, protects the vehicle from salt damage, and provides a warm transition between car and home.
Storage Space
With the average Canadian household accumulating seasonal equipment, tools, sports gear, and holiday decorations, garage storage is highly valued. Many buyers rank it alongside closet space in importance.
Vehicle Security
A locked garage provides protection against theft, vandalism, and weather damage. Insurance premiums can also be lower for vehicles stored in a garage versus parked on the street.
Workshop and Hobby Space
Many homeowners use their garage as a workshop, hobby room, or home gym. This versatility adds appeal, especially for buyers who need dedicated space for projects or fitness equipment.
EV Charging Capability
With the growing adoption of electric vehicles, a garage provides the ideal location for a Level 2 EV charger. This is becoming an increasingly important consideration for GTA buyers.
Resale Value Protection
Homes with garages consistently sell faster and for higher prices than comparable homes without. In competitive markets, a garage can be the deciding factor between otherwise similar properties.
Garage Value by Neighbourhood
The value a garage adds varies significantly by location. What is standard in one neighbourhood may be a premium feature in another.
Newer Suburbs
Churchill Meadows, Lisgar, Meadowvale Village
Double garage is standardIn these newer developments, a double attached garage is expected. Not having one puts your home at a disadvantage. The garage itself does not add premium value because it is the norm — but lacking one can reduce value by $40,000 to $60,000.
Established Urban
Port Credit, Lorne Park, Clarkson
Garage is a premium assetMany older homes in these areas were built with single or no garages. Adding a garage or having a larger one than neighbours can provide a competitive advantage and add $30,000 to $60,000 in value.
Condo and Townhouse Communities
Square One, City Centre, Cooksville
Parking type mattersFor condos and townhouses, having a garage parking spot versus an outdoor or underground spot can add $10,000 to $30,000. Indoor heated underground parking is particularly valued.
Premium Neighbourhoods
Lorne Park Estates, South Oakville, Old Oakville
Larger garages expectedIn upscale areas, a triple or oversized garage is common. The expectation is higher, so a standard double garage does not add as much relative premium. Custom features like heated floors and built-in storage add incremental value.
Garage Upgrades That Add Value
If you already have a garage, these upgrades can increase its appeal and your home's overall value.
Insulated Garage Door
$1,500 - $3,500Improves energy efficiency, reduces noise, and gives the exterior a modern look. High ROI upgrade.
Epoxy Floor Coating
$1,000 - $3,000Protects the concrete, is easy to clean, and gives the garage a finished, polished appearance that impresses buyers.
Built-In Storage Systems
$500 - $2,000Wall-mounted shelving, overhead racks, and pegboard systems maximise usable space and help the garage present well.
EV Charger Installation
$1,500 - $3,000A Level 2 (240V) EV charger is increasingly sought after. Forward-thinking upgrade that appeals to the growing EV market.
Heating System
$2,000 - $5,000A ceiling-mounted forced-air heater or in-floor radiant heat makes the garage usable year-round in Ontario's climate.
New Garage Door with Windows
$2,000 - $5,000A modern garage door with window inserts is one of the highest-ROI home improvements — often returning 90% or more of its cost.
Should You Build a Garage to Increase Value?
Building a new garage solely to increase your home's value is rarely a dollar-for-dollar investment. The ROI for new garage construction typically ranges from 40% to 85%, meaning you will not recoup the full cost at resale.
However, there are situations where it makes sense:
Important: Before building a garage, check your municipality's zoning bylaws, setback requirements, and lot coverage limits. In Mississauga, you will need a building permit and the project must comply with the City's zoning by-law. Consult with the City's planning department before committing to the project.
Frequently Asked Questions
How much value does a single-car garage add to a home?
In the Greater Toronto Area, a single-car attached garage typically adds $20,000 to $50,000 to a home's value, depending on the neighbourhood, overall condition, and what comparable homes in the area offer. In areas where most homes have double garages, a single garage may actually be seen as a shortcoming rather than an asset.
How much value does a double garage add compared to a single?
A double (two-car) attached garage generally adds $40,000 to $80,000 in value in the GTA market. The premium over a single garage is typically $20,000 to $40,000. In family-oriented suburbs like Mississauga, Brampton, and Oakville, a double garage is considered standard and its absence can be a significant disadvantage when selling.
Is it worth converting a garage into living space?
In most GTA neighbourhoods, converting a garage to living space is not recommended. The majority of buyers want a functional garage for vehicle parking, storage, and weather protection. A garage conversion can actually reduce your home's value if buyers in your area expect a garage. The exception may be areas where parking is available on the street or in a driveway and the additional living space is highly desirable.
Does a detached garage add as much value as an attached garage?
A detached garage typically adds less value than an attached garage of the same size — roughly 60% to 80% of the value an attached garage would add. Buyers generally prefer the convenience of an attached garage, especially in Ontario's cold winters. However, a well-built detached garage with electricity and heating still adds meaningful value to a property.
How much does it cost to build a garage in Ontario?
Building a new garage in Ontario typically costs $30,000 to $60,000 for a single-car detached garage and $50,000 to $100,000 for a double detached garage. An attached garage addition is more expensive, ranging from $60,000 to $150,000 or more depending on size and finishes. Municipal permits, site preparation, and foundation work are significant cost factors.
Does a heated garage add extra value?
A heated garage is a desirable feature in Ontario's climate and can add a modest premium — typically $5,000 to $15,000 — beyond the value of an unheated garage. Buyers appreciate the comfort, the protection it offers vehicles in winter, and the ability to use the space as a workshop year-round. However, the heating system should be energy-efficient to avoid concerns about operating costs.
