Some homeowners opt to build an ADU above an existing detached garage or workshop. If you are looking to avoid giving up any yard space to build a new ADU, an above-garage unit could be right for you. You would be able to add livable space to your property without giving up and parking spots or storage.
Keep in mind, building an ADU above your garage may not be as simple as it sounds. Often times, existing garages pose problems because they’re poorly constructed or dilapidated. This means they will require a lot of reinforcement to become structurally sound and could cost just as much as building an entirely new unit.
