What Is a Custom ADU?
A custom ADU is a secondary, independent living space built on your property, designed specifically to fit your lifestyle and preferences. It can be a detached home, a garage conversion, or an attached addition. Custom ADUs offer versatile options — from guest houses and home offices to rental units.

- Maximum Size: Up to 1,200 square feet for detached ADUs; attached ADUs can be up to 50% of the existing home’s living area.
- Maximum Height: Typically 16 feet for detached ADUs.
- Setbacks: Minimum 4 feet from rear and side property lines.
- Parking: Required for detached ADUs unless located near public transit.
- Utilities: ADUs must share utility connections with the primary residence; separate meters are not allowed.
- Owner Occupancy: Not required for ADUs, but junior ADUs (JADUs) require the owner to live on-site.
