Is Costco open on Labor Day 2026? Opening and closing hours for the holiday

L abor Day weekend is often one of the final major shopping periods of summer, with retailers offering discounts on everything from appliances and electronics to furniture, clothing and outdoor products.

But Costco members hoping to make a last-minute trip to their local warehouse on Monday will find the doors closed.

Costco will be closed on Labor Day 2026, which falls on Monday, September 7. The closure applies to Costco warehouses across the United States, meaning shoppers should plan their trips around the holiday rather than expecting their usual Monday opening and closing schedule.

Costco's own customer-service information confirms that September 7 is a closure date for its warehouse and membership services. Individual warehouse pages also list Labor Day as "Closed," removing some of the uncertainty that can arise when holiday schedules differ between retailers.

For shoppers, that means there will be no regular Costco warehouse opening hours on Monday. The retailer's normal schedules, which can vary between locations and between Executive and Gold Star/Business members, will resume after the holiday.

The decision is particularly notable because many competing retailers remain open on Labor Day .

Walmart and Target, for example, are among the major chains expected to operate, while several grocery stores and other retailers will also welcome customers. Costco is instead maintaining its tradition of closing on a number of major holidays.

Costco's Labor Day closure doesn't mean the deals disappear

The closure comes at a time when Costco shoppers may still be looking for Labor Day savings.

Costco's holiday promotions can extend beyond the physical warehouse schedule, meaning members can still find offers through Costco's online operation even when they cannot visit a warehouse.

However, customers should distinguish between warehouse availability and online shopping.

A Costco deal advertised online does not mean a local warehouse is open on Labor Day, and shoppers who need groceries, household supplies or other products in person should complete those trips before Monday.

Current September promotions also mean members have an incentive to check Costco's offers before and after the holiday. Recent deal coverage has highlighted discounts on food, personal-care products and household essentials running into the month.

The timing of Labor Day is also worth remembering. In 2026, the federal holiday is observed on Monday, September 7, creating a three-day weekend for many workers.

Government offices, banks and financial markets are also observing holiday closures, although many private retailers have chosen to remain open.

For Costco members, the safest approach is therefore to treat September 6 as the final opportunity to visit a warehouse before the holiday.

Regular Sunday hours vary by location, so customers should check their individual warehouse rather than assuming every Costco follows exactly the same schedule.

The retailer's official warehouse listings provide the most reliable way to check normal operating times for a particular location.

For example, Costco's warehouse pages display separate schedules for Executive members and Gold Star and Business members, while also identifying specific holiday closures.

Costco's other services are affected as well. Its customer-service page states that warehouse and membership phone support will be closed on September 7, while Costco.com online-order customer service, Costco Business Center support, technical support and Costco Travel will also be closed for the holiday.

Gas stations can also be affected. Costco's warehouse listings show that gasoline departments normally operate on schedules separate from the main warehouse, but individual location pages explicitly list Labor Day as closed at locations such as Sacramento and Alhambra.

When does Costco reopen after Labor Day?

Costco should return to its normal schedule on Tuesday, September 8, after Labor Day. Because opening times can differ depending on the warehouse and membership category, members should check their local Costco listing before setting out.

The bottom line is straightforward: Costco is closed on Monday, September 7, 2026, for Labor Day. There are no standard warehouse opening or closing hours to follow that day because the warehouses are not operating.

Anyone hoping to take advantage of Costco's Labor Day-related promotions should therefore shop ahead of the holiday, investigate available online offers, or wait until Tuesday when warehouses reopen.

With most of the retail sector remaining active over the holiday weekend, Costco's closure is one detail members will want to know before making a shopping trip.
