Antioch FAQ
How many guests can I have at an Antioch short-term rental?
Antioch has no STR-specific guest cap. Practical limits come from § 9-5.203 (which keys a dwelling unit to permanent single-family occupancy), the California Building Code's occupant-load limits for the unit, and any business license conditions. A property that operates as if it had 6+ guest rooms for paid stays could be classified as a hotel use under § 9-5.203.
Is there a maximum number of days I can rent my Antioch home short-term?
The City of Antioch has not adopted a hosted/non-hosted annual day cap. Note that unincorporated Contra Costa County does impose 90/180-day caps under Chapter 88-32, but those rules do not apply inside Antioch city limits.
Does the Antioch Rent Stabilization Ordinance apply to short-term rentals?
No. The City's Rent Program FAQ states the RSO exempts 'Hotels, vacation rentals, and other properties used for short-term rentals of no more than 30 days,' per Antioch Municipal Code § 11-1.08.
