Yes, all ADUs will require a new address! If you apply for a building permit under your current address, the building permit will be put on hold and require you to create a street numbering request (SNCA) before we're able to issue a building permit for the project. To apply for a street numbering slip, you must provide a plan that shows the location of the ADU relative to the existing structure, and/or floor plans showing the relationship to other unit(s) in the building, on a plot plan. Please note that adding an ADU to your property will increase its assessed value but the property record card through the Assessor's Office will not be updated to reflect the ADU's address.
