Thank you for the site plan. For a property to have an ADU there must be a primary home. Since the existing structure is the primary then it cannot be classified as an ADU unless you are also building a primary. You can proceed with a remodel as is and not have to classify this as an ADU because it is the only dwelling unit. If you are wanting the existing unit to be classified as an ADU then you will need a primary use, such as the duplex or triplex you are proposing.Would you like to proceed with the ADU and the duplex/triplex application or just remodel the existing home as is and come back when you are ready to submit for an ADU with a duplex/triplex development?
