Fast forward to 09/16/22, this location now requires appointments. Yes, West Sacramento PO Passport Office is also open on Monday to Saturday and no appointment necessary. But be patient since usually there's a wait. They don't have any amenities, such as bathrooms or food court. So eat before and use bathroom prior to coming in, unless your fasting that day and or have a strong bladder, then you're golden!
Sacramento P&DC in west sacramento has a passport office.
