Full Breakdown
270(E)(4) of the San Clemente Municipal Code bars short-term rental of accessory dwelling units outright: no ADU or JADU may be rented for a term shorter than 30 days, and that prohibition applies regardless of when the unit was created, meaning it covers ADUs built decades ago under prior versions of the ordinance as well as new construction. That effectively forecloses using a backyard ADU or garage-converted JADU as a nightly or weekend vacation rental anywhere in the City. 5, No Separate Conveyance, adds a related but distinct restriction on ownership rather than rental term: while an ADU or JADU may be rented out to a tenant, it cannot be sold or otherwise conveyed separately from the underlying property, meaning an owner cannot subdivide title and sell the ADU on its own.
On a single-family lot, the ADU or JADU must stay bundled with the lot and the primary dwelling in any sale; on a multi-family lot, it must stay bundled with the lot and all of the dwellings on it. 26 independently authorizes a separate sale, a narrow state law allowance for qualifying affordable ADUs sold to income-qualified buyers. 8, recorded against the property before any building permit issues.
Violations & Fines
Renting an ADU or JADU for stays under 30 days, or attempting to sell or convey it apart from the primary lot outside the narrow state-law exception, breaches the recorded deed restriction and exposes the owner to enforcement by the Planning Division, which can pursue legal action including an injunction against the unlawful use or abatement of the violation. Because the restriction runs with the land, it binds future owners even if a prior owner created the violation.
