Garage Apartment Plan Examples

Are you looking to create a garage apartment to add extra living space to your property? Could you use a rental unit, an in-law suite, or even a home office? Garage apartments are an excellent idea for people who want to add extra living space without cutting into their yard area. You can “go up” and build an apartment unit on top of the existing garage. Or convert the garage itself into an apartment.

Garage Apartment 3D Plan Examples

With garage apartment plans, you can create:

  • A separate rental apartment to generate extra income
  • An in-law suite for parents or relatives
  • A guest suite
  • An office or teen area
  • An empty nester living space on your property so that you can rent out the main house
  • A garage gym

One significant consideration is whether to build on top of the existing garage or remodel the current space. Let’s take a look at some options.

Garage Apartment Plans With Living Quarters Above

If you use your garage - perhaps for a car, as a workshop, or for storage - you may want to keep that area as it is. In that case, the best option for you may be to build extra living space above the garage. One consideration will be how to access the apartment - will you have an interior stairway or exterior? Additionally, the existing garage’s size will dictate how many square feet or square meters you have in which to work.

One Car Garage

If you have a single car garage, the living space above works best if it is a studio or 1 bedroom. One car garages are typically just 14-16 feet (about 4-5 m) wide and 20-22 feet (about 6-7 m) deep. You’ll likely be able to choose an open layout studio with a small kitchen area, one bathroom, and even some closet space. This size unit is best for one or two people. If you aren’t looking to create a sleeping area, it’s also a good size for a home office, art studio, teen hang-out room, or home gym.

Two Car Garage

If you have a 2 car garage, you have a lot more options. 2 car garages are typically 22-24 feet (6-7 m) wide by 20-30 feet (6-9 m) deep. You have enough space to create a 2 bedroom suite complete with a living room, kitchen, dining area, and bathroom. This size unit has more flexibility. You could have a single person or couple in the master bedroom, with a child in the second bedroom. Or, set up the spare bedroom as an office, study, or guest room.

Three Car Garage

If you have a 3 car garage, you have even more options. 3 car garages are typically 31-34 feet (9-10 m) wide by 20-30 feet (6-9 m) deep. With this more generous size, the floor plan could include a more extensive 2 bedroom suite complete with a living room, kitchen, dining area, and bathroom. Imagine a spacious living area for a couple. This size suite could also work for a family with one or two children. Another option would be for two roommates, each with their own master bedroom suite.

Single Level Garage Apartment Plans

If you do not use your garage for one or more cars, a much less expensive option may be to convert part or all of the actual garage into an apartment. After all, you already have the walls, roof, bare floor, electricity, and perhaps even plumbing. Another benefit of converting an existing garage is that the resulting living space will be on the ground floor. This may be important if you are creating an in-law suite or granny flat.
