Showing Nevada County rules
These are Nevada County's own ADU rules on file, shown with the California state rules they build on. Each item says which is which.
Where a Nevada County rule may conflict with state law or is being challenged, we show the California state rule instead. This covers limits on combining ADU types, size limits for attached ADUs, a deed restriction on every ADU, stricter city rules in city spheres of influence, height limits and owner-occupancy rules for junior ADUs.
