Counting Every Dollar: A Line-by-Line Look at Commercial Construction Budgets in McAllen, Corpus Christi, and San Antonio
Every commercial project starts the same way: an owner with a vision and a rough idea of what it should cost. Too often, that rough idea comes from a national average or a figure heard at a chamber of commerce meeting three years ago. By the time real bids arrive, the gap between expectation and reality has already derailed the project.
At SouthTexa Contracting, we believe owners deserve transparency before the first conversation with a builder. Here is what commercial construction actually costs across our region right now — and how to budget for the parts nobody can fully predict.
Where the Money Goes: Hard Costs vs. Soft Costs
Most owners focus on hard costs — the visible expenses like concrete, steel, and labor. But soft costs routinely add 25 to 35 percent on top of a construction budget, and forgetting them is the single most common budgeting mistake we see.
Hard costs include site preparation, foundation work, structural systems, exterior envelope, mechanical and electrical systems, interior finishes, and general conditions like equipment rental and site supervision.
Soft costs cover architectural and engineering fees (typically 6 to 12 percent of construction cost), permit and impact fees, surveys and geotechnical studies, legal and accounting services, insurance and bonding, and financing costs during the build.
Then there's land. In McAllen's fast-growing north side, commercial parcels in developed corridors can run $4 to $8 per square foot. Corpus Christi waterfront-adjacent and industrial-zoned land varies widely with flood zone designations. San Antonio's northwest and northeast growth corridors command the region's highest land prices, often exceeding $10 per square foot near major intersections.
Current Per-Square-Foot Ranges by Market
These figures reflect typical recent experience for conventional commercial construction — retail, office, and light industrial — excluding land purchase:
McAllen / Rio Grande Valley: Shell construction generally lands between $110 and $165 per square foot, with finished office space reaching $180 to $240. The Valley's competitive subcontractor market keeps pricing favorable, but border-region supply chains can add lead time on specialty materials.
Corpus Christi: Expect $120 to $175 per square foot for shell work. Coastal wind zone requirements — impact-rated glazing, enhanced roof anchoring, elevated structural connections — add real money, often 8 to 15 percent compared to inland construction.
San Antonio: As the region's largest market, San Antonio sees the widest range: $115 to $180 for shell, $200 to $275 for Class A office finishes. Labor rates run higher than the Valley, but the subcontractor pool is deeper, which helps on schedule-driven projects.
Add 10 to 20 percent for site work depending on drainage, utility extensions, and paving scope — and in South Texas, never skip the geotechnical report. Expansive clay soils from San Antonio through the Coastal Bend make foundation design a genuine cost variable, not a line-item afterthought.
Budgeting for Volatility: Steel, Lumber, and Labor
Material pricing has not returned to pre-2020 stability, and smart owners budget accordingly. Three practical approaches:
Use current quotes, not historical data. Steel pricing can move 20 percent within a quarter. Ask your contractor for material pricing valid at bid time and clarify how long that pricing holds.
Include a contingency you actually respect. We recommend 8 to 12 percent for projects in design development and 5 to 7 percent once drawings are complete. Owners who spend their contingency early on upgrades routinely find themselves short when the unexpected arrives.
Consider early procurement. For steel buildings and long-lead electrical equipment, ordering materials before full design completion can lock pricing — at the cost of some flexibility. It is a trade worth discussing with your builder early.
Labor is the quieter inflation story. Skilled trades across Texas remain in short supply, and prevailing wage dynamics mean contractors with established subcontractor relationships often deliver better pricing than the low bidder who must build a crew from scratch.
A Sample Cost Worksheet Before You Request Bids
Fill this out before your first contractor meeting. It sharpens every conversation that follows.
- Land cost: Purchase price + closing costs + survey
- Site development estimate: $8–$20/sf of site area (adjust for utilities and drainage)
- Building shell: Building square footage × market rate from above
- Interior finish allowance: Building square footage × $40–$90 depending on use
- A&E fees: 6–12% of items 2–4
- Permits and impact fees: $2–$6/sf depending on jurisdiction
- Insurance and bonding: 1.5–2.5% of construction cost
- Financing carry: Your lender's estimate for the construction period
- Contingency: 8–12% of construction costs
- Total project budget: Sum of all the above
If your financing and this worksheet don't align, it is far better to discover that on paper than halfway through a slab pour.
The Bottom Line
Numbers on a webpage are a starting point, not a substitute for a site-specific estimate. Soil conditions, wind exposure, utility availability, and municipal fee schedules will move your project up or down from these ranges. But owners who walk into the bidding process with a structured budget — one that accounts for soft costs and volatility — negotiate from strength.
