Full Breakdown
I. 80 that updated the chapter's implementation of Government Code Sections 66310 through 66342. 1. There's no seasonal or occasional-use exception written into the text: any lease term of 30 days or less falls on the wrong side of the line, meaning month-to-month or longer leases are the only compliant rental structure for these units. The restriction sits alongside the chapter's other development standards, unit size, height, setback, parking, and design compatibility, all of which a building permit applicant must satisfy before an ADU or JADU can be created in the first place.
Violations & Fines
Renting an ADU or JADU short-term breaches one of the development standards that made the unit's ministerial building permit approval possible in the first place. Because Section 8.80.040 states the chapter's standards apply to any building permit for these units, a documented short-term rental use exposes the property to the City's standard Title 8 zoning enforcement process, which can require the owner to cure the violation before the unit's compliant status is restored.
