The agency must act within 60 days of a complete application — and the ADU is deemed approved if it does not.
Owner-occupancy
CA state lawOnly for a JADU
No owner-occupancy requirement for ADUs (the prior sunset was removed). A JADU may require owner-occupancy, principally where it shares sanitation with the main house.
Impact-fee waiver
CA state lawWaived under 750 sq ft
An ADU of 750 sq ft or less pays no impact fees (the 750 sq ft threshold itself is exempt under § 66311.5); larger ADUs pay fees proportional to the primary dwelling. JADUs (≤ 500 sq ft) are exempt.
Permits required
CA state lawBuilding permit
Only a ministerial building permit — no conditional use permit or discretionary design review for a qualifying ADU.
Lemoore-specific factors that can change the answer
State law sets the floor, but these local conditions often decide whether a specific parcel works.
Pre-approved ADU plans (Cottage Home program)
City offers pre-approved building plans for ADUs to streamline permitting.
Lemoore limits detached ADUs on multifamily lots to 2 and requires a 15 ft front setback for detached ADUs, but allows pre-approved 'Cottage Home' ADU plans to expedite permitting.
