Accessory Dwelling Units (ADUs)

ADUs are a secondary dwelling unit with complete independent living facilities for one or more person. They are an innovative, affordable, effective option to increase the value and space of your home. Today ADUs are known by different names: granny unit, granny flat, in-law unit, in-law cottage, mother-in-law apartment, sidekick home, laneway home, backyard guesthouse, backyard cottage or secondary dwelling unit. ADUs are affordable in California as they do not require paying for land, major new infrastructure, structured parking, or elevators. Further can provide additional source of income for homeowners.

The first step of ADU is to have an architectural plan, if you don’t possess one we can help you connect with one of our trusted Architect partners in your area to get the Architectural Permit set prepared.
