A full-scale apartment or guest house will take you to the top of your budget and beyond at an average between $15,000 to $30,000. You'll need to make all the upgrades mentioned for a family room, along with a separate bath and kitchen. You'll need to run a gas line or a 220 outlet for the stove. You'll also want a private entrance for your apartment, which usually entails adding a fire door.

The first step in planning a garage conversion is deciding upon the room's new intended purpose. Do you need a place for teens to hang out at home with friends? Are you dreaming of a large, luxury man cave? Maybe you'd just enjoy an upgraded space to park your cars in winter - one that's fully insulated and climate controlled? Before you decide, keep a few factors in mind:

Is your garage currently only being used for storing things? Well, if it is, maybe you should consider putting it to better use. This article will explore the many possibilities a garage could give you, how to remodel it, and how to make sure you don’t break the bank doing it. We’ve divided it into different sections, each can be accessed through the links below, or you can simply scroll in order to read it in its entirety.


Look for a contractor who specializes in garage remodels - or at least one who has experience remodeling garages. Ask to see pictures of previous jobs such as the before and after garage conversion picture shown here. A good contractor should be able to show you garage conversion designs and you can also get some inspiration from looking online at garage remodeling ideas. Remodeling a garage is different than remodeling other areas of the home, and it helps to have a contractor who understands that.
Have a ballpark figure in mind. Determine what you can comfortably afford to spend on your garage remodeling or building project. Where does it fall in your list of home improvement priorities? Will you be spending 100% of your remodeling and construction budget on it? Having a clear idea of your price ceiling will help you avoid making choices that are too expensive or elaborate and having to scale back in the process.

Know your priorities. Will your garage be purely functional? If so, durable surfaces and systems trump expensive trappings. Make a list of what you’ll need, from storage to appliances to furnishings, and then rank every item in order of importance. That way, if you have to cut things as you get farther into the process, it will be easier to make choices.
You may have to drill holes through studs or through the top plate of walls to reroute wires. If so, be sure to center the holes on the stud. If the plastic-sheathed cables are too short to reach the next box when you reroute them, you can add a junction box and splice on a length of cable. The new box must be accessible either in the attic space or through a blank cover on the wall or ceiling.
If you're planning to maximize the space, add useful features, and otherwise make changes that are likely to appeal to a majority of homeowners, your renovation may end up being a worthwhile investment in your home's resale value. However, the quality of the work matters, especially if you're planning a major change such as converting the garage into a bedroom. Trading your garage space for a poorly insulated "bedroom" with no windows and the garage door intact won't do much to boost resale value.
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.
