Antioch, CA Short-Term Rentals: Occupancy Limits (2026)

California Health and Safety Code and the California Building Code set baseline occupancy standards that Antioch applies to all residential uses including short-term rentals. The common "2+1" formula — two persons per bedroom plus one additional occupant — or similar variations is the default, though Antioch may also reference the California Uniform Housing Code minimum square footage requirements (typically 70 sq ft for the first occupant and 50 sq ft for each additional occupant in a sleeping room). Short-term rental hosts should post the maximum occupancy clearly inside the unit and on their listing. Antioch Municipal Code addresses disorderly houses and nuisance properties, and properties that generate repeated complaints for excessive guests, noise, parking overflow, or party behavior may be declared a public nuisance under Chapter 4-1 and abated through code enforcement. The city's noise ordinance (Chapter 4-5) applies equally to STRs, and amplified music or large gatherings after 10 PM can result in citations. Hosts should also consider that CC&Rs in HOA communities often impose their own occupancy limits stricter than the city's. Commercial events (weddings, parties, corporate retreats) are generally prohibited at residential STRs without a Special Event Permit. Violations can result in fines, TOT license revocation, and in repeated cases, abatement action against the property owner.
