Antioch, CA Home Business: Customer Traffic Restrictions (2026)

901 sets the conditions a home occupation must meet to operate legally in an Antioch residential unit, and division (B)(10) is the flat rule on foot traffic: no customers or clients shall be permitted to visit the home at any time in conjunction with the home occupation. The only carve-out is for in-home music lessons, academic tutoring, or similar instructional uses, which may host no more than six students total in any 24-hour period, a cap that counts every student across all sessions that day, not per session.

The same section layers on other traffic-adjacent limits: employees at the site are restricted to residents of the unit plus one nonresident under division (B)(7), inclusive of all home occupation permits issued for the property, and delivery vehicles are limited to those which typically make deliveries to single-family neighborhoods, such as USPS, UPS, pickup trucks, and light vans, under division (B)(8). Division (B)(9) caps commercial vehicles at one per home, owned by the occupant, with a one-ton payload maximum, and bars food trucks, utility trailers, cargo trailers, and food carts outright.

A home occupation use permit is required before starting, and operators must sign an affidavit under division (D) committing to ongoing compliance; violating the client-visit rule can lead to enforcement or revocation, since permits are not transferable and are tied to continued compliance with division (B).
