- One ADU and one JADU may be built on any lot with an existing or planned singlefamily home.
- The single parking space requirement for the ADU is waived if the property is located within a half mile of public transit. Two parking spaces for the existing residence shall be maintained unless a garage or carport is demolished or converted to create an ADU. The space can be uncovered, tandem, and/or within setbacks.
- Total area for a detached ADU may not exceed 1,200 sq. ft.
- Total area for an ADU attached to a residence is capped at 50% of the size of the home.
- Take careful consideration of the location of the overhead power lines. Two-story ADUs often require greater rear yard setbacks to avoid overhead power lines.
- Utilities for the ADU may connect to the primary residence or, if you choose, separate services can be added.
- Ground-up ADUs are required to have a 4’ setback from the side and rear yard property lines.
- Existing garages that are converted to or replaced by an ADU are not required to meet setback requirements.
- For multifamily zoned properties, two detached ADUs can be added to the site and portions of the existing structure can be converted into ADUs.
- In the City of Los Angeles, ground-up ADUs must either be 10’ away or attached to any existing structures
