Accessory Dwelling Units (ADUs) are secondary dwelling units that are built on the same lot as a primary dwelling unit. ADUs provide opportunities to expand housing options on existing residential lots. An ADU can either be attached or detached from the primary dwelling and can provide opportunities for additional income, multigenerational living, or housing for caregivers. To support residents, promote affordable and diverse housing choices, the City allows up to two ADUs per lot. The City also offers permit-ready building plans at no cost to city residents.

The City has created resources to help you plan, permit, and build an ADU on your lot. Use these resources to help make decisions on adding an ADU (or two!) on your property, like placement, layout, and approximate size. Consider consulting with City staff on your design before you finalize plans. Staff may be able to help with advice on converting an existing structure or any unique circumstances with the project or your property.
