Cost per square foot is the benchmark contractors and appraisers both use, but it varies wildly by space. In 2026, a basic bathroom runs $150–$250 per square foot, a mid-range kitchen $250–$400, and a whole-house gut renovation of a Houston home typically lands between $100 and $200 per square foot.
The headline number only tells part of the story, however. Structural work, finish level, and whether you're moving plumbing or electrical all move the price dramatically. Here's our complete 2026 breakdown of renovation costs per square foot in Texas — and how to budget without surprises.
