Commercial Buildout / Tenant Improvement

$65–$180 per sq ft

A tenant improvement, or TI, turns a leased space into a working office, clinic, or shop. It only goes smoothly if one contractor keeps the permit, the trades, and the landlord on the same schedule. We build office, medical, dental, professional, and light-industrial TI space across Katy and west Houston. That includes demising walls, ADA-compliant restrooms, HVAC zoning, and electrical and data rough-in. We coordinate the plumbing, electrical, and HVAC ourselves, pull the City of Katy permit, and put a named project manager on your job.

What We Do

  • Office, medical, dental, professional, and light-industrial tenant improvements
  • Demising walls and ADA-compliant restrooms for new tenant layouts
  • Dedicated HVAC zoning and electrical and data rough-in
  • Specialized plumbing and gas for medical and food tenants
  • Permit and inspection scheduling, so occupancy is not delayed
  • A named project manager and a schedule built around your move-in

Why hire one contractor for the whole project?

We handle mechanical, electrical, and plumbing work in-house. We also handle City of Katy and Harris/Fort Bend County permits ourselves. That means one contractor instead of three. Every job gets a named project manager and a clean, documented permit record. No hidden change orders. No chasing separate subs.

Frequently Asked Questions

How much does a commercial tenant improvement cost in Katy, TX?

Commercial tenant improvements in the Katy area typically run about $65 to $180 per square foot. Basic office space is at the lower end, while medical, dental, and food-service spaces cost more because of the extra plumbing, gas, and HVAC work. We give a free, line-item estimate so you can see where the budget goes.

How long does an office or medical tenant improvement take?

A standard office TI in Katy usually takes about 6 to 12 weeks. Medical and dental fit-outs take longer because of the added plumbing, electrical, and HVAC work, equipment coordination, and inspections. The City of Katy permit and plan-review timeline is the main variable, which is why we handle permitting ourselves and put a named project manager on the job.

What's included in a commercial buildout?

A commercial buildout covers everything needed to turn a leased shell into a working business. That includes demising walls, ADA-compliant restrooms, code-compliant egress, HVAC zoning, electrical and data rough-in, finishes, and any specialized plumbing or gas the tenant needs. We coordinate the plumbing, electrical, and HVAC trades under one contract, so they don't collide in the field.

Do you build out medical and dental offices in the Katy area?

Yes. Medical, dental, and other healthcare tenant improvements are a regular part of our commercial work, including dedicated plumbing and gas, specialized HVAC, lead-shielded areas where required, and equipment coordination. We schedule inspections so occupancy isn't held up, and we assign one project manager you can call with any question.

Will my buildout be ready by my lease commencement date?

We build the construction schedule around your lease start date and target move-in date. We handle the permit ourselves, since plan review can otherwise cost you two to six weeks. You get a named project manager and regular schedule updates, so you can plan your move instead of guessing.
