Full Breakdown
Yuba County's Development Code requires that a person with legal or equitable title to the primary dwelling live on the property, in either the primary house or the junior accessory dwelling unit (JADU), as their legal domicile and permanent residence. The requirement doesn't apply if the property is entirely owned by a government agency, land trust, or nonprofit housing group. Before the county issues a building permit for a JADU, the owner must record a deed restriction in the chain of title barring the JADU from being sold separately from the primary home. This applies only outside Marysville and Wheatland, both of which enforce their own codes.
Violations & Fines
Skipping the deed restriction blocks JADU permit issuance outright; violating owner-occupancy after the fact is a recorded-covenant breach the county can enforce as a code violation.
