Interior and tenant build-out

Tenant build-out and interior finish-out in San Antonio and the Hill Country.

Office, medical, dental, and professional space finished on a tenant's schedule and a landlord's allowance, by a San Antonio commercial general contractor that answers the phone.

What is a tenant build-out?

Turning commercial space into your space.

A tenant build-out, also called tenant improvement or TI, is the interior construction that turns an empty, outdated, or shell commercial space into a finished space for a specific tenant. It covers layout, framing and drywall, ceilings, flooring, doors and millwork, plumbing, electrical, HVAC, lighting, and finishes, through to an inspected, occupiable space.

Trusted manages the whole sequence for tenants, landlords, and brokers: preconstruction, design coordination, permitting guidance, construction, and closeout. You deal directly with the people accountable for the job, and the schedule is built around your lease dates and your opening.

If the building itself does not exist yet, see ground-up construction. If you are buying an older property, see remodel and repositioning. And bring us in early: preconstruction is where a lease negotiation gets real numbers.

What we build out

Interior space for the way you work.

Every use has its own layout, systems, and finish expectations. Here is where tenants and landlords most often put us to work.

The tenant build-out process

Six stages from signed lease to opening day.

The same process whether the space is a small suite or a full floor. You always know what is next, what it costs, and who is accountable.

What is included

From empty suite to certificate of occupancy.

A build-out is a chain of dependent steps inside someone else's building. We manage each link and the handoffs between them.

Building a whole new structure instead? We handle ground-up commercial construction too.

Cost and schedule

What shapes the cost and timeline of a tenant build-out.

Every space is different, so we do not quote a price per square foot from a web page. These are the factors that move the number most, and the ones we price first.

  1. Existing condition

    What is already in the space, from ceilings and slabs to mechanical and electrical, changes the scope more than most tenants expect.

  2. Utilities and building systems

    Capacity for power, HVAC, plumbing, and data decides how much new work the space needs.

  3. Use and layout

    Medical, dental, and office layouts carry very different plumbing, mechanical, and wall requirements.

  4. Finish level

    Millwork, flooring, ceilings, and lighting drive cost as much as square footage does.

  5. Lease dates and allowance

    The TI allowance and rent start date set the budget ceiling and the schedule pressure.

  6. Permitting and long-lead items

    Review cycles, electrical gear, and storefront can control the start date and the finish date.

Common questions

Tenant build-out questions, answered.

What is a tenant build-out?

A tenant build-out, also called tenant improvement or TI, is the construction that turns an empty or outdated commercial space into a finished space for a specific tenant. It typically includes demising walls, framing and drywall, ceilings, flooring, doors, millwork, plumbing, electrical, HVAC, lighting, and finishes.

What is the difference between a tenant build-out and ground-up construction?

Ground-up construction creates the building itself, starting with the land. A tenant build-out finishes the interior of space inside a building that already exists, whether that is a shell, a second-generation space, or an older suite being repositioned.

What is a tenant improvement allowance?

A tenant improvement allowance, or TI allowance, is money a landlord contributes toward finishing a tenant's space, set out in the lease. We help owners and tenants price the work early, so the budget and the allowance can be compared before the lease is signed.

How long does a commercial tenant build-out take?

Timing depends on the size of the space, the condition of the building, permitting, and long-lead items such as electrical gear and storefront. During preconstruction we build a working schedule around your lease dates and target opening, so you know what is realistic before you commit.

How much does a tenant build-out cost in San Antonio?

There is no single price per square foot. Cost depends on the existing condition of the space, the amount of mechanical, electrical, and plumbing work, the finish level, and the use. We provide a preliminary budget with the assumptions spelled out, and the first conversation costs nothing.

Do you build out medical and dental offices?

Yes. Medical, dental, and professional offices are some of the most common spaces we finish. They need careful coordination of plumbing, mechanical systems, and finishes, so we plan the sequence with your design team early.

Can you work in an occupied building?

Yes. We plan access, noise, deliveries, and schedule with the property manager and neighboring tenants, so the work stays safe and disruption stays low.

Should I talk to a contractor before I sign a lease?

Yes. A build-out estimate during lease negotiation can change the deal, from the TI allowance to the delivery condition of the space. A call before you sign costs far less than discovering an issue afterward.

What does TIPS awarded contractor status mean for my project?

Trusted holds TIPS awarded contractor status through The Interlocal Purchasing System. For qualifying clients, that means we can be hired directly, without running a public hard-bid process, because we have already been publicly vetted.

Do you do tenant build-outs outside San Antonio?

Yes. We are headquartered in Spring Branch in the Texas Hill Country and build for owners across Bexar County, the Hill Country, the I-35 corridor, and South Texas, with experience in DFW, Houston, and the Rio Grande Valley. See where we build.
