Full Breakdown
050, Standards for Ministerial ADUs, conditions ADU approval on the owner living on-site. Junior ADUs are different. 030(E)(7) keeps the state-authorized residency condition: the JADU or primary residence shall be occupied by the owner of record unless the owner is a governmental agency, land trust, or housing organization. 030(C)(3), the property owner must record a declaration of restrictions stating that, if there is a JADU on the property, either the JADU or the primary dwelling will be owner-occupied. 030(C). Because the requirement travels with title rather than with any individual approval, a subsequent buyer of a property with a JADU inherits the same occupancy obligation unless the code or state law is amended.
The city verifies compliance through the recorded covenant rather than through periodic inspection, so enforcement is typically triggered by a complaint or by a title search showing noncompliance.
Violations & Fines
Occupying neither the JADU nor the primary home violates the recorded declaration of restrictions and is enforceable as a code violation under Temecula Municipal Code Section 1.20.030, punishable as a misdemeanor, up to a $1,000 fine and six months in jail, or more commonly through the administrative citation process in Chapter 1.21, which lets code enforcement staff impose escalating civil fines without a criminal filing.
