Years of rumors in New Braunfels are finally turning into a very big-box reality. Costco is officially on the way, slated to open in mid-May as the retail anchor of the Mayfair “town-within-a-town” development, bringing a large gas lot, a food court and the bulk-buy staples that have long sent Hill Country shoppers down the highway to other cities.
When and where
The New Braunfels warehouse is scheduled to open May 15, 2026, according to Community Impact. State project filings list the address as 235 Kohlenberg Road, Building 2, just off I-35 inside the Mayfair development, per the Texas Department of Licensing and Regulation.
Big building, big fuel lot
Builder Robinson Construction has the project listed as a roughly 160,000-square-foot, single-level warehouse and shows construction milestones on its project page. Robinson Construction Co. details the site scope and timing, while local coverage and photos have tracked the fuel island taking shape with about 32 members-only pumps. MySA reported the pump count as crews wrapped up exterior work.
What you'll find inside
Costco warehouses typically combine bulk groceries with a slate of extra services that regulars know by heart: pharmacy, optical, tire center, hearing-aid center and a busy food court. Company filings note that each warehouse carries fewer than 4,000 active SKUs, a tight assortment by big-box standards that is part of the chain’s model. Those companywide details and the ancillary-services approach are summarized in Costco.
Jobs and the incentive deal
To help land the warehouse, New Braunfels City Council approved multi-part sales-tax rebate agreements tied to the project. The structure and caps on those incentives are laid out in the council’s meeting file on New Braunfels Legistar. Local reporting and earlier filings have put direct store jobs in the low hundreds, with roughly 150 positions cited in paperwork related to the development, and warehouse management said in local statements the company is "thrilled to be bringing Costco's low warehouse prices to New Braunfels residents."
Membership, hours and early access
Costco membership currently costs $65 a year for a Gold Star personal plan and $130 for an Executive membership, according to the company’s membership page at Costco. The retailer recently reinstated early-shopping hours for Executive members at many warehouses, offering a 9 a.m. entry window that was reported by the San Francisco Chronicle, so shoppers will want to check the New Braunfels warehouse page for the exact schedule on May 15.
Traffic and neighborhood impact
The Mayfair master plan, combined with the Costco site, is reshaping traffic and retail expectations along the I-35 corridor, and city planning and incentive documents show officials coordinating road and intersection upgrades to absorb the new demand. Local project and council records outline both those infrastructure steps and the sales-tax rebate arrangements tied to the store, which are detailed in the council file on New Braunfels Legistar.
When doors open, Costco’s New Braunfels debut will put a noticeable new dot on the Hill Country’s retail map, bringing closer access to bulk goods, gas at member pricing and several in-store services. Members and job seekers should keep an eye on Costco’s site for membership details and hiring updates ahead of the May 15 opening. Expect parking and peak-day traffic to be heavy in the early weeks as the region’s Costco faithful converge on the new warehouse.
