Every project comes down to cost, so it only makes sense to start there. According to our garage remodeling cost estimator, the average garage remodel runs $8,582. Keep in mind, this takes the full garage into consideration. That includes the garage door, flooring, windows and plenty of other renovations. For those remodeling one aspect of their garage, of course, expect the final price to be much less. In fact, we have even seen garage remodels cost as low as $900.

Pick: Pick what your new room is going to focus on. Your small garage can either do one thing perfectly or a lot of things partially. Think of it like any small room in your home. Your small bedroom wouldn’t be able to be a bedroom, media room, work space, and storage area. Your small garage can’t do all of these things either. So pick one focus and ensure your plan addresses it. Some average room sizes to help you pick are:


The floors of your new space are a unique issue. Your garage is built with drainage in mind. Code requirements mandate that the concrete slab has a slope built into it to ensure water drains away from the home. The installation of the subfloor will correct the slope issue of your floor. Using a subfloor allows your new space to be converted back into a garage should the next home owner wish to do so.
The first step is often fixing a cracked floor or leveling it, and sometimes even staining it to make it look more attractive; the repairs cost $500-$12,500, and stains range from $2 to $10 per square foot. Drywall is typically put up, which costs from $1 to $2 per square foot. Adding boards for a storage space above the garage typically costs about $2 per square foot.
A garage can be so much more than a messy catch-all for items that don’t fit inside the home. Through a remodel, it can be made into an organized storage unit or a workshop, or simply made more functional, with room for at least one car. Turning a standard 600-square-foot, two-car garage into a well-organized, tidy space is less expensive than most remodeling projects. Because a garage already has a floor, walls and a roof, the primary tasks are finishing the framed walls and adding organizational systems.

A 'Ready to Sell' garage remodel will give you the best ROI possible without the need for a permit. It may include finishing interior texture (already sheetrocked), painting, and changing a few light fixtures. This level is perfect for those who are preparing their home for sale and tends to be cosmetic in nature in order to present the home well to potential buyers.
Homeowners who are used to house paints should have no trouble applying either and cleaning up afterward. First, apply some H&C cleaner degreaser, a mixture of heavy-duty detergent and phosphoric acid. You simply sprinkle it on the garage floor with a watering can, work it in with a broom and let it foam the floor clean. Then, rinse the floor and let it dry. The stain is applied with a roller. It's ready for foot traffic in one hour and car traffic in 72 to 96 hours depending on temperature and humidity.
A garage remodel is usually much cheaper than a home renovation because the foundation, roof, and walls are already built. Many garages also have electrical and plumbing installed to some extent. The actual cost of a garage remodeling project, however, depends on what the renovated space will be used for. While a new home gym won't require much in the way of amenities, converting a garage to an office, apartment, or bedroom requires adding significantly more creature comforts.
