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.


Is your garage currently only being used for storing things? Well, if it is, maybe you should consider putting it to better use.

Garages have minimal insulation, so if you’re renovating your garage to turn it into an office or family room, you’ll certainly need to add insulation and HVAC. Your insulation pro will start with the ceilings and floors. Beyond that, they may or may not choose to add insulated garage doors (if doors are being kept). All in all, adding new HVAC and insulation can add $2,000 to $3,000 to your garage remodel cost.
Besides a brand new room, there are plenty of other benefits that come with remodeling garages. First and foremost, if you simply update your garage with new flooring, windows, insulation or garage organizers, you instantly increase the value of your home. While you may not see a 100% return on investment the day you sale, you will surely get more than you would have before the garage renovation.
Purge: Look at your pictures, think of them in terms of a small space. Purge anything that doesn’t work in a small space. With minimal square feet to work with, you don’t need a spa bathroom. While a game room sounds great, the space needed for a pool table is probably not there. Take out anything from your plan that doesn’t fit in a smaller space.

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.
A garage remodel can take many different forms. Some finished garages are transformed into guest bedrooms, game rooms, man caves or even master bathrooms. Others go the traditional route and clean it up to just keep their cars inside. The traditional route is certainly more cost-effective, but after analyzing national garage remodeling costs, the average price to renovate a garage is roughly $10,000.
Determine needs vs wants: There is always a difference between what you WANT in your garage, and what you NEED. While you may want a high end entertainment complex, do you need it? Before you begin your project sit down and make a list of needs, and wants. By creating a prioritized list you keep yourself from overspending. Once you have your needs addressed, throw in a few wants.

An insulated garage will stay cooler in the summer and warmer in the winter. The first step is to be sure the attic is well ventilated. Check to see how many attic and roof vents you have. A good rule of thumb is a total of 1 sq. ft. (144 sq. in.) of vent opening per 300 sq. ft. of attic divided between the soffit and roof vents. For a typical 20 x 22-ft. garage, you’d need about six 4-in. x 12-in. soffit vents and two standard square roof vents. Make sure your ventilation is effective by installing vent chutes between the trusses. Vent chutes have a channel that prevents blown insulation from blocking the airflow from the soffit vents to the attic space. Plug the area under the vent with wood blocking or plastic and a chunk of fiberglass insulation to prevent wind from blowing up through the insulation or insulation from filling the soffit.
Leaky doors and windows let in uncomfortable drafts and increase heating and cooling costs. Check your garage service door to be sure it has good weather stripping and a threshold that seals tightly to the bottom of the door. In most cases, if your service door is missing a threshold and weather stripping, it’s more efficient to replace the door with a new, weather-tight version. You can buy an inexpensive prehung metal exterior door at home centers and lumberyards.
