Not if the ADU is within half a mile of high-quality transit or is part of an existing structure or garage conversion. Otherwise, one off-street space per unit or bedroom may be required.
How long does ADU approval take?
State law requires ministerial action within 60 days of a complete application. Plan check timing varies, and building permit inspections follow separately.
