Planning a bulk shopping run requires knowing exactly when warehouse doors open. The Fairfax location on West Ox Road sees heavy local traffic, so checking the schedule before you head out saves you from a wasted trip or a jammed parking lot.
Standard warehouse hours for Gold Star and Business members run from 10:00 AM to 8:30 PM Monday through Friday, 9:30 AM to 7:00 PM on Saturdays, and 10:00 AM to 6:00 PM on Sundays. Executive members get early entry starting at 9:00 AM on weekdays and Saturdays, and 9:00 AM on Sundays. Knowing these specific entry windows helps you bypass peak checkout rushes and grab what you need without a headache.
Weekly Schedule Breakdown by Department
Not every department inside the warehouse runs on the exact same clock. Specialty services like the pharmacy, tire center, and gas station operate on independent timetables that often extend past or shorten before main warehouse hours.

Holiday Schedule Closures
Costco closes its warehouse doors across the country on major holidays. If you're planning a holiday dinner or a weekend cookout, mark these closures on your calendar so you don't find yourself locked out.
The Fairfax warehouse shuts down completely on New Year's Day, Easter Sunday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. On Christmas Eve and New Year's Eve, the store typically closes early—usually around 5:00 PM or 6:00 PM—to give employees time to head home. Major holidays like Presidents' Day, Veterans Day, and Columbus Day operate on normal business hours. You can double-check active operational status directly through the Costco Warehouse Locator.
Smart Shopping Strategies for the Fairfax Location
The West Ox Road warehouse gets packed quickly, especially on weekends and right around the dinner hour on weekdays. A few tactical adjustments make your trip much smoother.
- Target the sweet spot windows: Arrive right when Executive member hours begin if you want to dodge the heaviest crowds. Alternatively, the final hour before closing (around 7:30 PM on weekdays) sees a sharp drop in foot traffic.
- Park near the side perimeter: The main entrance lanes fill up instantly. Parking closer to the tire service center or side perimeter lanes lets you pull in and out without getting stuck in gridlock.
- Use the gas station during off-peak times: Lines at the pumps peak between 4:00 PM and 6:30 PM as local commuters head home. Visiting early in the morning before 8:00 AM or later in the evening keeps your wait time under five minutes.
- Book tire and optical appointments online: Don't just walk into the tire center expecting immediate service. Use the Costco Tire Appointments portal to lock in a slot, as walk-ins depend entirely on daily bay availability.
