Total STR Ban for Properties with ADUs: The city strictly prohibits the issuance of a vacation rental license for any property that contains an ADU, regardless of the zoning district. This applies to the main home as well, not just the ADU. Guest House Distinction: Unlike ADUs, 'Guest Houses' (defined as having no kitchen) do not disqualify a property from vacation rental eligibility, provided they are rented combined with the main unit.
