Summary
El Monte requires any accessory dwelling unit or junior ADU to be rented for longer than 30 consecutive days, flatly prohibiting short-term rentals, and separately bars detached and attached ADUs from being sold apart from the main house.
L.Limitations to Sell, Convey or Rent an ADU.1.Detached ADUs shall not be sold or otherwise conveyed separate from the primary residence, except as otherwise provided in Section 65852.26 of the California Government Code.2.Attached ADUs or junior ADUs shall not be sold or otherwise conveyed separate from the primary residence.3.The rental of ADUs or junior ADU shall be for a duration longer than 30 consecutive calendar days. Short-term rentals shall be prohibited.
Full Breakdown
L, titled Limitations to Sell, Convey or Rent an ADU, sets three rules for how ADUs and junior ADUs can be occupied. 1). 2). 3 requires that any rental of an ADU or junior ADU run longer than 30 consecutive calendar days, and expressly states that short-term rentals are prohibited. This mirrors the minimum-stay threshold used elsewhere in California to distinguish a lease from a short-term or vacation rental, meaning an El Monte property owner cannot list a backyard ADU on a nightly or weekly booking platform.
The restriction applies regardless of whether the ADU is attached, detached, or a junior ADU, and applies on top of the separate owner-occupancy requirement for junior ADUs found in subsection R. 1, the city does not screen for rental intent at permitting, but the 30-day minimum remains a standing condition of the unit's lawful use once built.
Violations & Fines
Renting an ADU or junior ADU for 30 days or less violates Section 17.110.030.L.3 and is enforceable as a zoning violation under Title 17's general enforcement provision, Section 17.10.160.C, a misdemeanor punishable under Chapter 1.24 (General Penalty). The Community Development Department's Code Enforcement Division may cite the property, and the city may pursue abatement of the unlawful short-term rental use as a public nuisance, or seek a Superior Court injunction, under Section 17.10.160.D-E.
