Cost of Building a Garage Loft Apartment

Cost

• The cost of adding a garage apartment varies depending on its size and the materials you use. The size of the loft greatly depends on the size of the garage. For example, a 24-by-24 foot, or 576 square foot, two-car garage allows for a 300-square foot loft, usually accessed only by a drop down ladder. A larger 728 square foot two-car garage is a better starting point, allowing for a 380-square foot loft apartment with full stairs. The total garage square footage with the loft equates to 1108 square feet, and costs between $35,000 and $45,000 in building cost on average, which includes building the garage and furnished loft, according to the Housing Forum website.

Materials

• The quality of materials can have a significant effect on the total building cost for a garage loft apartment. The quality of the finishing materials such as toilets, tubs, sinks, appliances, light fixtures, flooring and other details like trim all affect the total cost. Upgrading materials can raise the cost as much as 15 to 20 percent, according to the Housing Forum website. Other material considerations include the roof style, siding, doors and other designer add-ons add up fast.

Other Cost Considerations

• The material prices for building a garage loft apartment also vary greatly depending on the seasonal influences and location. The building cost might vary greatly within regions from urban to rural areas. The southern states have the lowest cost, while the northeast states have the highest building costs in the nation. Buy the materials or a kit, and do as much of the labor as possible to save 15 to 20 percent. Hire a contractor to complete whatever work you can't do yourself.

Benefits

• Building a garage loft apartment has many worthy benefits, including curb appeal, designated space for guests, or space for a home business. The building cost may add value to the property and make it more appealing. A garage loft apartment can also bring in some extra rental income that can end up paying for the building cost and upkeep of the new addition to your garage.
