G128–E1 – Modern Garage Apartment Plans


Having a functional modern garage apartment gives you several options. A short-term rental or long-term rental on your residential premises is convenient, with some revenue, and adds value to your property. Maybe you want to use the accessory building for an office or overflow for an out-of-town guest. This building solves the usual problem of accommodating your visitors, who will spend a few days with you.

We suggest building a DADU, which stands for a Detached Accessory Dwelling Unit. The G128 plan is an example of a 1 ½ story Garage Apartment DADU building, with the garage at 994 square feet and the living space upstairs at 700 square feet. The apartment square footage was calculated at 5′-0″ knee walls and above. This accessory building was built as a 2 car garage plan with an apartment above. However, it could be modified to be a 3 car garage plan with the apartment above.


The height of this modern garage apartment is under 25’-0” tall from the finish concrete slab with an eave height of less than 10’-0″ from the finish concrete slab. In Nashville, DADU’s cannot be taller than your home or are limited in height to 25′-0″ or 27′-0″ depending on your zoning. If you are in the Nashville area, we can help determine your zoning and allowable DADU accessory building.
