How Much Does a Commercial Build-Out Cost in Houston in 2026?

One of the first questions we hear from business owners planning a commercial build-out in Houston is: "How much is this going to cost?" It is a fair question — and one that deserves a straight answer. At Primal Construction, we have completed hundreds of commercial projects across Houston's diverse neighborhoods, from the Energy Corridor to EaDo, Midtown to the Medical Center. In 2026, commercial build-out costs in Houston range widely depending on the type of space, the condition of the shell, and the level of finish you need. This guide breaks it all down.

What Is a Commercial Build-Out?

A commercial build-out — sometimes called a tenant improvement or TI — is the process of converting a raw or partially finished commercial space into a fully functional business environment. This can mean building out an empty shell space from the ground up, reconfiguring an existing office layout, or transforming a vanilla retail box into a full-service restaurant. The scope of work, and therefore the cost, varies enormously between these scenarios.

Houston Commercial Build-Out Costs by Space Type (2026)

Based on current market conditions in the Houston metro area, here are realistic cost-per-square-foot ranges you should plan around for 2026. Keep in mind these figures reflect Houston's competitive labor market — which generally runs 5 to 10 percent lower than Austin and Dallas-Fort Worth, giving Houston businesses a meaningful cost advantage. Office build-outs typically run between $75 and $200 per square foot for a standard tenant improvement, or up to $330 per square foot for ground-up corporate office construction. Retail spaces run $120 to $250 per square foot for basic build-outs, with higher-end boutique or experiential retail reaching $300 or more. Restaurant build-outs are among the most expensive category due to commercial kitchen requirements, ventilation, grease traps, and specialized plumbing — expect $200 to $450 per square foot for a full-service restaurant, or $150 to $300 per square foot for a fast-casual concept. Medical office construction is the highest-cost category, ranging from $270 to $440 per square foot in Houston, driven by specialized plumbing, electrical, and code compliance requirements.

Key Factors That Drive Build-Out Costs in Houston

The condition of your existing space is one of the biggest cost drivers. A "vanilla shell" space — one that has concrete floors, exposed ceilings, and basic MEP (mechanical, electrical, and plumbing) rough-ins already in place — will cost significantly less to build out than a true cold dark shell with nothing inside. Second-generation restaurant spaces, where a prior tenant already installed a grease trap, hood system, and ventilation infrastructure, can save a new restaurant operator $50,000 to $150,000 or more compared to building from scratch. Location also matters. Projects in high-density areas like Uptown, Downtown Houston, or the Texas Medical Center corridor often face higher subcontractor costs and tighter site logistics. Suburban markets like Sugar Land, The Woodlands, Katy, and Pearland tend to offer more competitive pricing and faster permitting timelines.

What Does a Build-Out Budget Actually Include?

A comprehensive commercial build-out budget should account for: general construction labor and materials (framing, drywall, flooring, ceilings); mechanical, electrical, and plumbing systems; HVAC — a significant line item in Houston given the climate; permit fees, which for commercial projects in Houston typically range from $500 for small remodels to $20,000 or more for large ground-up construction; architect and engineer fees, generally 8 to 15 percent of total construction costs; furniture, fixtures, and equipment (FF&E), which is separate from construction costs; and a contingency buffer of 10 to 15 percent to cover surprises. Many business owners are surprised to learn that construction costs represent only part of total project costs. At Primal Construction, we walk every client through a complete project budget during our pre-construction process so there are no surprises when invoices arrive.

Tenant Improvement Allowances: Reducing Your Out-of-Pocket Cost

If you are leasing rather than owning your commercial space, your landlord may offer a tenant improvement allowance (TIA) — a per-square-foot contribution toward your build-out costs. In Houston's current market, TIA offerings vary widely based on lease length and landlord motivation. Longer leases in spaces that have been sitting vacant often command stronger TIA packages. A well-negotiated TIA can offset a substantial portion of your construction budget, but it rarely covers everything. Understanding what your TIA actually covers — and what it does not — is critical before you sign a lease.
