Yes — Costco is coming to Mansfield. The first Mansfield Costco is under construction at the northeast corner of Lone Star Road and FM 917, with a targeted opening of May 2026, according to a project filing submitted by Costco’s architect to the Texas Department of Licensing and Regulation. The roughly 157,281-square-foot warehouse is backed by up to $8 million in performance-based incentives approved unanimously by the Mansfield City Council on May 12, 2025.

This will be Mansfield’s first Costco, ending years of Mansfield residents driving to the Arlington warehouse — or farther out to Hurst or Fort Worth — for a Costco run.

When does the Mansfield Costco open?

Costco itself has not issued a corporate press release with a public opening date, but the project filing with the Texas Department of Licensing and Regulation — submitted by Seattle-based MG2 Architecture on behalf of Costco Wholesale Inc. of Issaquah, Washington — lists:

• Construction start: October 13, 2025
• Substantial completion: May 21, 2026

That May 21, 2026 date is the contractor’s projected completion, not a guaranteed grand-opening date — Costco typically opens a warehouse a few days to a few weeks after substantial completion. Several local outlets, including the Mansfield Record and the Fort Worth Star-Telegram, have reported the opening as “May 2026.”

Bottom line: plan on late spring 2026, with the exact day to be announced by Costco closer to opening. As of May 2026, Costco has not posted the Mansfield warehouse on its official “New Locations” page with a firm opening day.

Where exactly is the Mansfield Costco being built?

The Costco site is at the northeast corner of Lone Star Road and FM 917, just off Texas 360 / U.S. 287 in southern Mansfield. The TDLR filing places it in the 76063 ZIP code and notes the site is in Johnson County — Mansfield straddles the Tarrant/Johnson/Ellis county lines, and this parcel sits on the Johnson County side.

(Note: the Fort Worth Report’s May 2025 coverage described the parcel as the corner of Lone Star Road and U.S. 287, while the TDLR filing and Mansfield Record use Lone Star Road and FM 917. Those references describe the same project — Texas 360, U.S. 287 and FM 917 all converge in this stretch of southern Mansfield.)

A specific street address has not been published in city records reviewed as of May 2026.

How big is the store?

According to the TDLR project record, the new construction is a 157,281-square-foot Costco Warehouse — a standard full-size warehouse, not a smaller Costco Business Center or gas-only outpost. Reporting from the Mansfield Record indicates the project also includes an attached fuel station valued separately at $2.9 million.

The Chapter 380 incentive agreement approved by city council requires Costco to deliver “a minimum of 150,000 square feet” — the 157,281-sq-ft filing comfortably exceeds that threshold.

What did the city approve, and how much is it costing taxpayers?

On May 12, 2025, the Mansfield City Council voted unanimously to approve a Chapter 380 economic development agreement with Costco, according to the Fort Worth Report and Mayor Michael Evans’ official recap of the meeting.

Under Texas Local Government Code Chapter 380, cities can offer grants and sales-tax rebates to private businesses to spur economic development. The Mansfield agreement is structured as a performance-based deal, meaning Costco only receives the incentives if it delivers on specific commitments. Per the agreement:

• Costco’s commitments:
  • Build a store of at least 150,000 square feet
  • Invest a minimum of $25 million in capital
  • Generate a minimum of $40 million in annual taxable sales
• The city’s commitments:
  • Reimburse Costco up to $1.5 million for infrastructure costs
  • Rebate 50% of the general-fund sales tax generated by the property back to Costco
  • Total city contribution is capped at $8 million over the life of the agreement

Jason Moore, executive director of the Mansfield Economic Development Corporation, told the Fort Worth Report that “Costco’s presence is expected to anchor the corridor and catalyze further development, with the $40 million minimum taxable sales threshold functioning as a robust baseline for long-term economic benefit.”

The total project cost listed in the state filing is $19.5 million for the warehouse itself, with the fuel station valued separately.

Was there opposition?

The May 12, 2025 council vote was unanimous. The first close vote came at the Mansfield Planning and Zoning Commission on June 2, 2025, where commissioners approved the required zoning change 5-1, according to the Fort Worth Report. Commission Vice Chair Blake Axen cast the lone “no” vote; Commissioner Jennifer Thompson was absent.

The site was already inside an existing planned development, but the previously approved plan called for a mix of 60 townhomes, 275 multifamily units and 14 acres of commercial use — a substantially different land use than a single big-box anchor. The zoning change was needed to swap that mix for the Costco footprint.

Specific concerns raised by commissioners or residents during the public hearing were not detailed in the reporting reviewed as of May 2026. Mansfield Observer has reached out to the city’s planning department for the full commission minutes.

How many jobs will it bring to Mansfield?

Specific employment numbers for the Mansfield warehouse have not been publicly confirmed by Costco or the city as of May 2026. The Chapter 380 agreement references “local hiring” as a commitment but does not specify a headcount.

For comparison, Costco’s Weatherford warehouse — which opened in March 2025 — brought “more than 200 jobs” to Parker County, per WFAA. Costco’s standard hiring pattern for a new warehouse typically ranges from 200 to 250 employees, but Mansfield-specific figures will need to come from Costco’s eventual hiring announcement, which usually happens roughly six months before opening.

How will this change traffic at Lone Star Road and FM 917?

A formal Costco-specific traffic impact analysis has not been published in materials reviewed for this article. Separately, TxDOT has a long-planned project to widen FM 917 from I-35W to south of BU 287P from two lanes to an interim four lanes — and ultimately six lanes — across a 9.4-mile stretch. That widening project depends on available funding and could begin as early as 2029, meaning it will arrive after Costco opens.

Residents along FM 917 should expect a noticeable traffic increase during peak weekend hours, particularly Saturdays, which are historically the busiest day for any Costco warehouse.

What this means for the corridor

Mansfield’s planners are clearly positioning the Lone Star Road and FM 917 corridor as a major retail and entertainment node. Other recent or planned arrivals in the same general area, per Living Local Texas, include Chuy’s (already open), LongHorn Steakhouse, Hideaway Pizza and BoomerJack’s Grill & Bar.

The Fort Worth Report noted in a separate January 2026 piece that the council approved a $2.5 billion Staybolt Street entertainment district, signaling that Costco is one piece of a much larger commercial buildout for southern Mansfield.

About 157,281 square feet — a full-size Costco warehouse, not a smaller Costco Business Center. The project also includes an attached fuel station, per the Mansfield Record.

How many jobs will Costco bring to Mansfield?

When did the City of Mansfield approve Costco?

Up to $8 million total, structured as a performance-based incentive. That includes up to $1.5 million in infrastructure reimbursement plus a 50% rebate of general-fund sales tax generated by the property. Costco only collects if it builds at least a 150,000-square-foot store, invests at least $25 million, and generates at least $40 million in annual taxable sales.

What does this mean for the Arlington, Hurst and Fort Worth Costcos?

Today the closest Costco to Mansfield is the Arlington warehouse, with the Hurst and Fort Worth stores farther out. Once the Mansfield store opens, it will become the default Costco trip for most local residents — cutting a drive that now runs into the tens of minutes down to a few. Those existing warehouses will likely see lighter weekend volume from Mansfield-area shoppers but will continue to serve their own trade areas.

How much does a Costco membership cost?

As of 2026, a Costco Gold Star (basic) membership is $65 per year, and an Executive membership is $130 per year, according to publicly listed Costco pricing. Executive members earn a 2% reward on qualified Costco purchases, capped at $1,250 per year, and get earlier shopping hours.

Is this a regular Costco or a Costco Business Center?

A regular, full-size Costco Wholesale warehouse. The TDLR filing describes it as a “new 157,281 sq ft Costco Warehouse” — Costco Business Centers are typically smaller and serve commercial customers, while the Mansfield store is sized as a standard membership warehouse with a fuel station.
