ADU size depends on lot size and zoning.
In Santa Cruz county, ADUs inside the "utility zone" are limited to 10% for normal lot sizes up to a max of 640 sqft. Large lots can have an ADU up to 800 sqft.
Outside of the "utility zone" ADUs can be as large as 1200 sqft if your lot is greater than 1 acre.
