Superior ADUs has pre-designed, developed, and engineered these Model ADUs so you don’t have to. A great amount of time and money goes into custom designing an ADU from scratch, which can make building an ADU quite costly. Superior ADUs has already developed the plans for each model, so you don’t have to spend the time and money to work with an architect, one on one. You simply select a model and the plans are ready to be submitted to the city for approval. This greatly speeds up the process and reduces the expense of paying an architect to draw up a new set of plans. Thus, our Model ADUs are less expensive than if you were to have a custom ADU built on your own.
