In 2025, we are seeing a spike in the number of homeowners considering adding a garage to a house, specifically by expanding to a third car garage or building a detached garage for extra space.
Before moving forward with this project, there are several factors to consider. A common concern is: How much of the garage addition cost can be recouped when selling a home? Homeowners also ask, How much value does adding to a garage contribute to a home’s resale price?
In this article, we’ll outline the key factors that influence how a garage addition to an existing garage or a new detached garage can impact your home’s value.
How a Garage Addition to an Existing Garage or a Detached Garage Affects Home Value
The value you can retain from adding a garage to a house largely depends on factors like location, construction quality, market conditions, and entry cost. However, what we have seen is that homeowners can recoup about 65-85% of the garage addition cost through an increase in home value, depending on certain factors.
How Does a Garage Add Value to a Home? 6 Key Factors
1. Location
In areas where homes with garages are highly sought after, homeowners may recoup a higher percentage of their investment. If garages are less common in your neighborhood, the impact on resale value may be lower.
2. Quality
A garage built with high-quality materials that complement the style of your home is more likely to attract buyers and contribute to a higher return on investment (ROI).
3. Market Conditions
In a hot real estate market, homes with additional features like a garage tend to attract more buyers and sell at a premium. If demand is high, sellers may see the benefits of a detached garage reflected in a higher selling price, as buyers often prioritize extra storage and parking space.
4. Size & Functionality
The size and design of the garage also play a role in its value. A well-designed, functional space that provides room for cars, tools, and extra storage is more attractive to buyers. For those considering adding a third-car garage, this addition can enhance both convenience and storage capacity, making it a desirable feature for many homeowners. A new garage door installation can further improve functionality while enhancing curb appeal, giving buyers even more reason to see value in the space.
5. Cost
If you are not wise with the contractor(s) involved in the project, you can end up way over traditional costs, making it much harder to recoup your investment. While going for “the lowest bid” may seem tempting, it often leads to issues down the line. There is a middle ground. Keeping the cost of building a detached garage or adding a third-car garage within a reasonable range will give you a better chance of maximizing your return.
The lower the entry cost, the more margin you have when you sell—but don’t sign up for a construction horror story! Be prudent in who you hire.
6. Design
There are some beautiful garage doors on the market! Pick one that will make your project pop. If you’re adding a detached garage, consider a design that complements your home’s exterior to enhance curb appeal. Remember, you are choosing a garage door that you love—and that the next buyer will love, too. So, choose wisely!
At the end of the day, your house is only worth what someone is willing to pay for it—regardless of what an appraisal says. If you’re considering adding a garage to a house, remember that more garage space or better curb appeal never hurts when selling a home. Most Americans value and covet garage space and are willing to pay a premium for a property that has undergone such a project.
Your Garage, Your Gain
From selecting the right contractor to choosing residential garage doors that enhance your home’s aesthetic, every detail matters. A poorly executed garage addition can be a costly mistake, while a thoughtfully designed one can boost both functionality and property value.
