San Antonio build-out and renovation cost per square foot, 2026 guide

Six weeks was the number a restaurant group had in mind for new finishes in a space they had just leased off Loop 410. An electrical panel still running on original 1990s wiring behind the break room wall changed that number before we ever opened a finish sample. What is already inside a San Antonio space moves the build-out budget more than anything on a mood board.

What is already there decides more than what you are adding

A retail, office or restaurant space that already carries adequate electrical capacity, working HVAC and stubbed plumbing in roughly the right places is a build-out. A space that does not is a renovation with a mechanical upgrade riding along inside it, and the two price very differently even at the same square footage. We walk the existing conditions before we price anything, because a change-of-use build-out, a warehouse office converting to a showroom, a retail shell converting to a medical suite, often needs a bigger electrical service and a different HVAC zoning than the shell was built with.

Building type and the systems nobody sees

An office build-out with a straightforward layout and standard finishes sits at the light end of any square-foot number. A restaurant with a full kitchen, a medical suite with dedicated circuits and specialty plumbing, or a hotel guest-room renovation sits at the heavy end, because the space is mostly systems and finishes, not open floor. Owners tend to underestimate the mechanical, electrical and plumbing share of an interior budget most of all, since none of it is visible on a walk of the empty shell.

A planning range, and where it comes from

Owners still want a number to plan around, so here is one, offered carefully. In our planning for San Antonio interior work, a straightforward office or warehouse office build-out has run from the low tens of dollars per square foot on the light end to the low hundreds for a fuller finish, and restaurants, medical suites and hotel renovations from the middle hundreds up, depending entirely on the mechanical and plumbing scope involved. Hold this as a planning figure only, since scope, existing conditions, finish level and the bid year all move it, and it does not substitute for pricing your actual space. Only your drawings and a walk of the actual space produce a figure you can build to.

Why 2026 is its own year

The growth along the Austin corridor, around the medical center and near the military bases has not slowed, and the trade market shows it. Finding an open crew takes longer than it used to, certain materials still run behind on delivery, and permit counters across the metro are handling more submittals than they were staffed for. A cost figure from a couple of years back is not something you can simply carry forward. That is why we price close to the actual bid date: conditions shift enough between the planning conversation and mobilization to move the number.

Getting a number you can actually use

A floor plan of the existing space, photos or a walk-through, a program of what you want the space to do, and your target finish level give us what we need to build a trade-by-trade budget. Add your target opening date too, because the schedule shapes the price: a tight timeline can mean overtime hours, ordering long-lead fixtures and equipment early, or pulling crews from our own shop instead of waiting on a sub's calendar. Framing, drywall, paint, tile, stone and millwork all run through our own payroll, which lets us hold the schedule and the number together instead of waiting on someone else's availability to set either one.
