It will be easier for homeowners to build Accessory Dwelling Units (ADUs) as a result of new California real estate laws taking effect Jan 1, 2021.
ADUs are also called in-law units, granny units, secondary dwellings or simply backyard cottages. A Junior ADU (JADU) is less than 500 sq ft and built within an existing single family residence.
The new regulations require cities and counties to give automatic approval for ADUs without applying any local development rules for ADUs if:
- The ADU is created from existing space in a home or other structure, it has exterior access, and has setbacks sufficient for fire safety.
- The ADU is detached, under 800 sq ft, 16 ft in height, and has 4-foot side/rear setbacks.
- Both an internal JADU and one detached ADU are allowed to be added.
