Did you know that a new garage door has the potential to bring a 96 percent return on investment (ROI)?

Other garage renovations can bring in a great ROI as well, but it’s important to consider how much you’respending so you can know how much you’ll get back. Luckily, we’re here to take you through all the potential costs to expect.

Read on to learn everything you need to know about how much it’ll cost to remodel a garage.

Type of Renovation

The first thing you’ll need to determine is the level of work you plan on doing. There are always levels of work that affect your project’s final price, so it’s important to determine that before anything else.


The average cost of a partial garage remodel averages anywhere from $500 to $5,000.

Partial remodels can look different, but they often improve on one specific thing. This could mean a new garage door or floor coating (check out the best garage floor coating here). They’re usually meant to make an old garage look newer to improve saleability, but they don’t change much in terms of structure.


For a full garage conversion, you can expect to pay anywhere from $7,000 to $15,000.

This is the most common type of remodel if you plan on using your garage for something like car storage or as a workshop. That means new floor coating, high-quality cabinets, a new garage door, ceiling, and even walls.

The point here is to make your garage more appealing, functional, and easy to care for. 


Finally, you have the choice to convert your entire garage. This is often more affordable than adding on, ranging anywhere from $20,000 to $75,000. It has the potential to increase your property value.

It’s an especially appealing option if you’re about to list your home for sale. Buyers might lose out on car storage, but a well-done garage conversion will appeal to the right buyer.

Factors That Influence Cost

While the type of remodel you’re considering is what has the most effect on the price, there are other things to keep in mind. Here are a few of the most important factors to consider. 


The amount of labor you opt for is going to play a large role in the final cost of your garage remodel. Typically, though, the more time and people needed on-site, the more you can expect to pay.

General contractors will usually charge a flat rate depending on the project, ranging anywhere from 10 to 20 percent of your final costs.


Permits only matter if you’re changing the purpose or structure of your garage. You’ll need what’s known as a “conversion” permit, so be sure to check with your county, city, and state before you start.

If you find that it’s required, you can typically expect to pay around $1,400.


Plumbing only matters if you plan on converting your garage into an extra room, kitchen, utility room, or some other space that requires running water. This can look like adding an entire bathroom or a small sink to clean off after your projects are complete.

The final cost depends on the overall scope of your project, but you can typically expect to $1,500.


Most garages are going to be connected to electrical, so you won’t need a lot of work here. However, if you need new light switches, outlets, or even overhead lighting, you can expect to pay around $275 to $400.

Interior Walls

In your garage, you’ll likely have three of the four walls that are necessary to enclose it, but you’ll also need to consider things like drywall and paint. If you’re adding closets or bedrooms into that space, you’ll also need to consider the cost of supplies for those.

Typically, this will cost around $2,000.


While part of the interior walls, insulation is its category since it’s optional. However, if you plan on spending a lot of time in this room, it’s smart to at least consider it. This material will help keep the room comfortable throughout any time of the year, whether it’s hot or cold.

On average, you can expect your insulation to come in at around $1 per square foot, whether you opt for traditional or open-cell spray foam. 

Exterior Walls

If you have to close in a fourth wall, there are a lot of choices you’ll have for the material.

Typically, wooden boards will run you $7.50 per square foot, while stone or brick can range from $9-11 per square foot. Vinyl is a great choice for anyone on a budget, coming in at around $1.50 per square foot.

Door Removal

You can’t forget about properly disposing of that old garage door, though.

If the remodel crew won’t take care of things, you can expect to pay around $75 to $100 to have someone else come to professionally remove and dispose of it.

If you’d like to get crafty, you can opt to upcycle your old door to use the metal for things like end tables or outdoor decorations.
