How Davis's pre-designed ADU plans work

The City of Davis offers free pre-designed ADU plans in three sizes (300 sq ft studio, 565 sq ft one-bedroom, 740 sq ft two-bedroom) and three styles: Adobe, Agrarian and Mid-Mod.
The plans are already plan-checked, so review is quicker and plan check fees are reduced. They are treated as Type 1 ADUs, so lot coverage, floor area ratio and open space limits don't apply.
The City doesn't accept changes to its pre-designed plans, and they must meet the 4 ft minimum setback.
A California licensed general contractor is required before the building permit is issued.
