Attached or Detached Accessory Dwelling Units (ADU/DADU) dramatically increase the property value of a home while adding ample space for you to live and/or work. ADU’s also offer potential tax advantages compared to bedroom or basement home offices. Some clients transform former their garages into profitable apartment rental units, vacation rental spaces, yoga studios, recording studios, production or repair workshops and more.

Accessory Dwelling Unit
A legally permitted dwelling unit that is attached to a single family house, but has a separate entrance. These units typically have their own kitchens, bathrooms and living areas. ADU’s can be renovated from an existing part of the home or built onto an existing part of the home. They might also serve a special purpose as a commercial yoga or fitness studio, recording studio or rehearsal space.

- Off the street parking is required for ADUs except in certain lowrise zones or urban villages.
