Full Breakdown
270(E)(7) of the San Clemente Municipal Code splits owner-occupancy treatment by permit date and unit type. An ADU permitted after January 1, 2020 but before January 1, 2025 carries no owner-occupancy requirement whatsoever, reflecting the period when state law suspended that condition statewide. For any ADU permitted on or after January 1, 2025, the code now requires that a natural person holding legal or equitable title to the property reside there as their legal domicile and permanent residence, unless another applicable law overrides it. Junior accessory dwelling units are treated more strictly regardless of when they were permitted: all JADUs require a natural person with title to reside on the property, in either the primary dwelling or the JADU itself, as their legal domicile and permanent residence.
That JADU owner-occupancy rule has one carve-out: it does not apply where the property is entirely owned by a governmental agency, land trust, or housing organization rather than an individual. 8, which is recorded against the property before a building permit issues, runs with the land, and binds future owners, and it is enforced by the Planning Division on behalf of the City.
Violations & Fines
A property owner who fails to comply with the recorded deed restriction, including its owner-occupancy terms, exposes the owner to legal action by the City, which may pursue any remedy available at law or equity, including an injunction against using the unit in violation of the recorded restriction or abatement of the illegal unit. The deed restriction can only be removed after the owner shows the Planning Division that the ADU or JADU has actually been eliminated, such as by removing the kitchen facilities, and a Planning Division determination on that request can be appealed under the code's standard appeal provisions.
