Full Breakdown
020(E) prohibits 'transient lodging uses for remuneration' in residential districts generally and defines 'transient' as a stay of less than thirty consecutive days, so an ADU rented for 30 days or less is treated the same as any other illegal short-term rental of a residential unit. 140 the unit falls under. 140(B), so the unit can be occupied under a longer-term lease but cannot be marketed as a separately owned or short-term rental property. Chino Hills has no separate short-term rental ordinance elsewhere in its code, making this 30-day floor inside the ADU chapter the operative local restriction on renting these units for less than a month.
Violations & Fines
Renting or listing an ADU or JADU for a stay of 30 days or less violates § 16.10.140(D) and, because the code treats such stays as prohibited transient lodging, § 16.10.020(E) as well. Under § 1.36.010 and § 1.36.020, that is enforceable as a misdemeanor with up to a $1,000 fine and six months in county jail, or the city may issue an administrative citation under Chapter 1.18, with fines set by council resolution and the right to an administrative hearing and Superior Court appeal.
