Summary
Carson requires the lot's legal or equitable owner to live in either the main house or the junior ADU as a permanent residence, with an exception for agencies, land trusts, and housing groups.
Owner Occupancy for Junior Accessory Dwelling Units. A natural person with legal or equitable title to the lot must reside in either the principal dwelling unit or the junior accessory dwelling unit as the person's legal domicile and permanent residence. However, this owner occupancy requirement shall not apply to any junior accessory dwelling unit owned by a governmental agency, land trust, or housing organization.
H. Deed Restriction and Recordation Required. Prior to the issuance of a building and/or grading permit for an accessory dwelling unit or junior accessory dwelling unit, the property owner shall execute a deed restriction, the form and content of which is satisfactory to the City Attorney. The City will record the deed restriction on the property with the County Recorder's Office, and the property owner shall pay all recording costs. The deed restriction shall notify future owners of the prohibition on separate conveyance, the restriction on short-term rentals, the approved size and attributes of the unit, and the owner occupancy requirements, if applicable. For junior accessory dwelling units, the deed restriction shall also include a restriction on the size and attributes of the unit that conforms with Government Code Section 65852.22. The deed restriction shall run with the land and remain in effect so long as the accessory dwelling unit and/or junior accessory dwelling unit exists on the lot.
I.
Full Breakdown
Carson Municipal Code § 9122.1(G)(3) imposes an owner-occupancy requirement specifically on junior accessory dwelling units (JADUs, the smaller units created within an existing house): a natural person holding legal or equitable title to the lot must make either the principal dwelling or the JADU their legal domicile and permanent residence. The requirement does not apply to a JADU owned by a governmental agency, a land trust, or a housing organization. Notably, this owner-occupancy condition applies to JADUs but is not imposed on full-size detached or attached ADUs under this section.
Violations & Fines
Renting out both the main house and the JADU with no owner living on-site breaches the occupancy condition recorded in the property's deed restriction, which can trigger code enforcement action and jeopardize the JADU's legal status.
