If you are leasing commercial space in San Antonio, the phrase "tenant finish-out" hides an enormous range of possible cost. Two suites of identical size on the same street can differ by two or three times in price to build out, depending on what the landlord hands you and what your business needs behind the walls. This guide breaks down realistic per-square-foot estimates for the San Antonio market and, more importantly, explains what actually moves those numbers so you can budget before you sign.
What Tenant Finish-Out Actually Covers
A tenant finish-out (also called a build-out or tenant improvement, TI) is the work that turns raw or previously occupied lease space into a functioning location for your business. That can mean framing and drywall for new rooms, flooring, paint, ceilings, lighting, electrical and data, plumbing, HVAC distribution, storefront glass, restrooms, and any specialty systems your use requires. It is different from ground-up construction because you are working inside an existing building envelope, which helps on cost but also means you inherit whatever the previous tenant or the base building left behind.
That inheritance is the whole ballgame. The single biggest variable in any finish-out estimate is the condition of the space on day one, and understanding those conditions is the key to reading any price quote you receive.
San Antonio Finish-Out Cost Ranges Per Square Foot
The figures below are estimates for the San Antonio and Central Texas market and will vary with your specific scope, finishes, and space condition. San Antonio tends to run more affordable than Austin, Dallas, or Houston: local labor rates are generally 10 to 20 percent lower than those metros, and the region overall prices commercial construction at roughly 0.85 to 0.98 times the national average. Use these as planning brackets, not quotes:
- Cosmetic refresh (paint, flooring, lighting, minor finishes in already-finished space): roughly $15 to $35 per square foot.
- Moderate office or retail remodel (some new walls, moderate MEP changes, better finishes): roughly $35 to $70 per square foot.
- Full build-out of a vanilla-shell or lightly finished suite: roughly $60 to $130 per square foot.
- Specialty spaces such as restaurants, bars, and medical/dental: roughly $150 to $300+ per square foot, driven by kitchen, grease, gas, plumbing, and equipment loads.
For a typical San Antonio office or retail tenant, most projects land somewhere in the $45 to $135 per-square-foot band once you account for a realistic finish level and code work. Restaurants and clinics sit well above that because of the mechanical, plumbing, and health-code infrastructure they require.
The Factors That Move Your Price the Most
Two projects with the same square footage rarely cost the same. Here is what separates a low estimate from a high one:
- Shell condition: A cold dark shell (bare concrete, no HVAC, no restrooms, stubbed utilities) can run 30 to 50 percent more than a vanilla shell that already has basic walls, a finished ceiling, lighting, HVAC, and a restroom. Second-generation space from a prior tenant can save money, or cost more if their layout and systems do not fit you.
- Mechanical, electrical, and plumbing (MEP): Reusing the previous tenant's HVAC and electrical is the most expensive assumption in the business. Undersized units, worn rooftop equipment, and insufficient electrical service often have to be replaced, and that swings budgets hard.
- Your use type: Restaurants, medical, and salon/spa uses carry heavy plumbing, ventilation, grease, and gas requirements. General office and retail are far lighter and cheaper per foot.
- Finish level: Builder-grade paint and vinyl plank sit at one end; custom millwork, stone, glass partitions, and designer lighting sit at the other. Finishes alone can double a per-foot number.
- Code and accessibility upgrades: Changing the use of a space, or exceeding certain thresholds, can trigger ADA and Texas Accessibility Standards work, fire-sprinkler or alarm upgrades, and updated exits, costs that are not obvious when you first walk the space.
Do Not Forget Soft Costs and San Antonio Permitting
The per-square-foot numbers above are hard construction costs. On top of those, budget another 10 to 15 percent for soft costs: architectural and engineering drawings, permit and plan-review fees, and project management. These are frequently excluded from a landlord's allowance, so read your lease carefully.
On the permitting side, plan on the City of San Antonio's Development Services commercial plan review taking roughly four to eight weeks depending on complexity and department workload. Commercial permit fees are set by occupancy group and square footage. Any project valued at $50,000 or more must also be registered with the Texas Department of Licensing and Regulation (TDLR) for accessibility review, which carries a state filing fee and requires plans to reach a Registered Accessibility Specialist within a set window. You will not get a Certificate of Occupancy, and cannot legally open, until all inspections pass and fees are paid. These estimates reflect current San Antonio practice and can change, so confirm fees with Development Services for your address.
How to Get a Number You Can Trust
The reliable path is simple: get the space's shell condition in writing, nail down exactly which soft costs your TI allowance covers, and have a contractor walk the suite before you commit to a lease term. Texas landlords commonly offer TI allowances in the $20 to $50 per-square-foot range for office and retail, and the gap between that allowance and your true build-out cost is money out of your pocket, so you want that gap quantified before signing, not after.
An experienced local contractor can spot the expensive surprises early: an HVAC unit near end of life, an electrical panel that will not carry your equipment, or a layout change that trips accessibility requirements. For a straight, San Antonio-grounded estimate on your specific suite, TexPro Contracting's commercial finish-out team can walk the space, flag the cost drivers before you sign, and give you an honest range for your scope, so your budget reflects the real building, not a generic per-foot average.
Frequently Asked Questions
What is the average commercial finish-out cost per square foot in San Antonio?
Most San Antonio office and retail finish-outs land in the $45 to $135 per-square-foot range, with cosmetic refreshes as low as $15 to $35 and full build-outs of raw shell space reaching $130 or more. Restaurants and medical spaces typically run $150 to $300+ per square foot. These are estimates that vary with shell condition, finishes, and your use type; a walkthrough is the only way to get an accurate number.
Does the landlord pay for the tenant finish-out?
Sometimes, partly. Texas landlords commonly offer a tenant improvement (TI) allowance of roughly $20 to $50 per square foot for office and retail leases. If your build-out costs more than the allowance, you cover the difference. Allowances also frequently exclude soft costs like architecture, engineering, and permits, so confirm exactly what is included in your work letter before signing.
Why is a vanilla shell cheaper to finish out than a cold dark shell?
A vanilla shell already includes basic essentials: framed and finished walls, a ceiling grid, lighting, HVAC distribution, and often a restroom, so you are building on top of usable infrastructure. A cold dark shell is essentially bare concrete with stubbed utilities, meaning you pay to add all of that from scratch. The same space can cost 30 to 50 percent more to finish out as a cold dark shell.
How long does the San Antonio permitting process take for a commercial build-out?
City of San Antonio commercial plan review typically takes about four to eight weeks depending on project complexity and current department workload. Projects valued at $50,000 or more also require TDLR accessibility registration and review, which runs in parallel. You cannot receive your Certificate of Occupancy or open until all inspections pass, so build permitting time into your schedule from the start.
What hidden costs surprise San Antonio tenants during a finish-out?
The most common surprises are mechanical: an HVAC unit that is near end of life, an electrical service too small for your equipment, or plumbing that does not match your layout. Beyond that, accessibility (TDLR and ADA) upgrades, fire-sprinkler or alarm work triggered by a change of use, and soft costs (design, engineering, permits at 10 to 15 percent of construction) catch tenants off guard. A pre-lease walkthrough with a contractor flags these early.
Is it cheaper to build out commercial space in San Antonio than in Austin or Dallas?
Generally, yes. San Antonio labor rates tend to run 10 to 20 percent lower than Austin and Dallas, and the region prices commercial construction at roughly 0.85 to 0.98 times the national average. Combined with predictable permitting and year-round building weather, San Antonio is usually the most cost-effective of the major Texas metros for tenant finish-out work.
