There are many types of ADU foundations. Abodu offers a stem wall foundation in our ADUs because it uses less concrete (which is more sustainable), lets you easily get to the utilities under the ADUs for any fixes or upgrades, and keeps moisture problems at bay better than the typical slab foundations, since stem walls raise the ADU off the ground.

ADUs usually come equipped with several essential appliances, including, but not limited to:

  • Stove or cooktop

  • Refrigerator

  • Oven

  • Dishwasher

  • Washer and dryer

  • Water heater
