W. Katy, TX - Gas Expansion

Costco Gasoline at 23645 Katy Freeway in Katy, Texas, completed a fuel facility expansion. The project, filed with the Texas Department of Licensing and Regulation (TDLR) as W. Katy, TX - Gas Expansion, converted an existing four-lane fuel site into an eight-lane facility. The construction added 25,782 square feet of canopy coverage, increasing the total area by 11,100 square feet. The building passed its final TDLR accessibility inspection in September 2026, confirming the work is complete.

Scope and Cost

The scope of work involved adding four multi-product dispensers to the existing structure, resulting in a total of eight dispensers. This expansion included all associated site improvements required for the new layout. The estimated cost for this addition was $4,268,324. Based on the 25,782 square feet of new canopy area, the cost equates to $166 per square foot. This figure is above the Harris County median of $100 per square foot for similar additions to existing buildings.

MG2 Architecture Corporation served as the design firm of record for the project. Joshua T Ronson was the registered accessibility specialist responsible for ensuring compliance with state standards. The project was privately funded on private land for private use. It was registered with TDLR in April 2025, and plan review was completed that same month. Construction began in June 2025, with a scheduled completion date of August 2025. The final inspection passed in September 2026, marking the end of the regulatory process for this specific filing.
