Soledad-specific factors that can change the answer
State law sets the floor, but these local conditions often decide whether a specific parcel works.
Fire sprinklers not required for ADUs if not required for primary dwelling
ADUs do not trigger new fire sprinkler requirements unless the main home is also required to have them.
Soledad limits detached ADUs on multifamily lots to two, below the state default of eight. The city explicitly sets a 1,200 sq ft maximum for both detached and attached ADUs, and requires owner occupancy only for JADUs.
