Summary
Fresno County requires the titled owner of a parcel with a junior accessory dwelling unit to live in either the main house or the JADU as a legal domicile, with a recorded deed restriction enforcing the rule, unless a government agency or housing organization owns the property.
Owner Occupancy Requirements. Junior Accessory Dwelling Units shall be subject to an owner-occupancy requirement. A person with legal or equitable title to the property shall reside on the property in either the primary dwelling or Junior Accessory Dwelling Unit as that person's legal domicile and permanent residence. However, the owner-occupancy requirement of this paragraph does not apply if the property is entirely owned by another governmental agency, land trust, or housing organization.
Full Breakdown
030(B)(4)(c)(2): "Owner Occupancy Requirements. Junior Accessory Dwelling Units shall be subject to an owner-occupancy requirement. A person with legal or equitable title to the property shall reside on the property in either the primary dwelling or Junior Accessory Dwelling Unit as that person's legal domicile and permanent residence. " This requirement applies only to Junior Accessory Dwelling Units (JADUs), the converted-space category limited to under 500 square feet with an efficiency kitchen, not to standard attached or detached ADUs. 030(B)(4)(c)(3) backs the rule with a recorded deed restriction: before a Building Permit issues for a JADU, the owner must record a deed restriction with the County Recorder stating the unit cannot be sold separately from the primary dwelling and is restricted to the approved size and attributes.
The deed restriction runs with the land, binds future owners, and can only be removed if the Director confirms the JADU has actually been eliminated, such as by removal of the kitchen facilities, subject to appeal from the Director's determination.
Violations & Fines
Failure of a property owner to comply with the recorded deed restriction, including the owner-occupancy condition, is enforceable by the Director for the benefit of the county through legal action, which can include an injunction against use of the JADU or abatement of the illegal unit.
