What to Expect Inside the New Costco in West Roseville

What does the new Costco in West Roseville offer — and what’s missing (like diesel)?
The long‑awaited West Roseville Costco has finally opened on Baseline Road. Shoppers are excited about the new warehouse, gas station, car wash, and more — but there’s one notable absence for diesel drivers.

A Long Anticipated Opening for West Roseville

After years of planning and anticipation, Costco officially opened its new West Roseville warehouse at 5200 Baseline Road on January 23, 2026 — anchoring the Baseline Marketplace retail project. Costco’s expansion has been a major local topic because there wasn’t a Costco location conveniently located on the west side of Roseville until now.

This new location is expected to be a big draw for West Roseville residents and nearby communities — cutting down travel time for Costco members who used to drive to the Stanford Ranch or other area warehouses.

Warehouse Features & Inside Highlights

Here’s a snapshot of what you’ll find inside and around the new Costco:

🛒 Full Warehouse Shopping

Like every Costco, the West Roseville warehouse offers bulk groceries, Kirkland Signature products, seasonal items, home goods, electronics, apparel, and more — all at Costco pricing and value.

⛽ Large Gas Station — Minus Diesel

The Costco gas station next to the warehouse has opened ahead of the main store. It offers a large set of gasoline pumps — about 40 positions — so even busy times move quickly.

However, diesel fuel is not available at this location, which has disappointed local drivers who hoped to fill up closer to home.

🚗 New Car Wash Facility

One of the unique features of this Costco is the on‑site car wash, located adjacent to the gas station. It’s operational now and usually priced around $8.99 per wash — a popular choice for members driving through after filling up.

🍔 Food Court & Services

Like other Costco warehouses, you’ll find a food court serving classics like hot dog and soda combos, frozen treats, pizza slices, and more, perfect for a quick bite during your shopping trip.

The location also has departments for:

• Pharmacy

• Optical

• Tire service

• EV charging stations

• Membership services
