Summary
Pleasanton bars short-term rentals of accessory dwelling units: Municipal Code Section 18.106.030 sets a 30-day minimum rental period for every non-exempt and statewide-exemption ADU, and Section 18.106.080 requires junior ADU stays to run longer than 30 days. Owners must also join the city's rent-monitoring program.
The rental period for statewide exemption accessory dwelling units and non-exempt accessory dwelling units shall be at least 30 days.

Full Breakdown
" The rule applies to every ADU permitted in the R-1, RM, MU, C-C and A districts and to units built in planned unit developments zoned for residential use, closing the door on nightly or weekly vacation rentals of a backyard cottage or converted garage unit. 070(E), giving planning staff an ongoing record of what ADUs actually rent for. 080(F) caps occupancy of the JADU/primary-unit pair at one other party per rented unit and requires that "the rental period shall be longer than 30 days," with the owner-occupant serving as a signatory on any lease so the city can verify compliance.
Because a JADU owner may rent either the primary house or the JADU but not sublease either through a third party, the ordinance functions as Pleasanton's local bar on Airbnb-style stays for both ADU types. 140.
Violations & Fines
Section 18.140.010 makes any use of a site contrary to Title 18 "unlawful and a public nuisance," directing the city attorney to pursue abatement, removal or injunctive relief in court, with available remedies treated as cumulative rather than exclusive. A short-term-rental listing for an ADU or JADU is a permit-condition violation the planning division can refer for code enforcement, and repeat violations can support revocation of the underlying zoning approval.
