Full Breakdown

14(c) of the Downey Municipal Code reads in full: Rental Term. No ADU may be rented for a term that is shorter than 30 days. This prohibition applies regardless of when the ADU was constructed. 14(d), except where Government Code § 66341 requires otherwise. Because the 30-day floor applies retroactively to every ADU citywide, an owner cannot list an older, pre-2025-ordinance ADU on a short-term platform just because it predates the current chapter; the restriction attaches to the unit itself, not to the permit that created it.

14(f), filed with the Los Angeles County Recorder and the Community Development Department, that locks in owner-occupancy and bars separate sale of the JADU from the primary home. While that deed restriction applies specifically to JADUs, the 30-day minimum rental term in subsection (c) is written to cover ADUs generally, meaning both full ADUs and JADUs across every zone where they are permitted, R-1, R-2, R-3, R-3-O, and M-U, are locked out of nightly or weekly rental use. 14(f)(6).

Violations & Fines

Renting an ADU or JADU for fewer than 30 days violates § 9414.14(c) and exposes the property owner to code enforcement action by the Community Development Department, including citation and the same abatement remedies available for other zoning violations. For a JADU with a recorded deed restriction, the Community Development Director can additionally seek an injunction or abatement order under § 9414.14(f)(6) to stop the illegal short-term use.

Frequently Asked Questions

Can I rent my Downey ADU on Airbnb for a weekend?
No. Section 9414.14(c) sets a 30-day minimum rental term for every accessory dwelling unit in the city, so nightly or weekly stays are prohibited outright. The rule applies to all ADUs regardless of when they were built or permitted, so there is no grandfathering for older units.
Does the 30-day rental minimum apply to Junior ADUs too?
Yes, § 9414.14(c) covers ADUs generally, which includes JADUs. JADUs carry an additional recorded deed restriction under § 9414.14(f) requiring owner-occupancy of one unit on the property and barring the JADU from being sold separately from the primary home.
Can I sell my ADU separately from my house in Downey?
No, except in the narrow case Government Code § 66341 allows. Section 9414.14(d) bars selling or separately conveying an ADU from the primary lot, and JADUs carry the same restriction plus a recorded deed covenant enforceable by the Community Development Director under § 9414.14(f).
