Commercial Tenant Improvements & Build-Outs in Port St. Lucie, FL

Gizze Construction Commercial Contractor

Commercial Tenant Improvement Contractor Serving Port St. Lucie, Stuart, Jensen Beach, Fort Pierce & the Treasure Coast

Moving into a new commercial space is exciting—but turning an empty shell into a fully operational business requires experience, planning, and a licensed General Contractor who understands every step of the process.

At Gizze Construction, we specialize in commercial tenant improvements, commercial remodeling, office renovations, retail build-outs, restaurant construction, medical office remodeling, and change of occupancy projects throughout Port St. Lucie and the Treasure Coast.

Whether you're opening your first business or expanding into a larger location, our team manages the entire process—from planning and permitting to the final Certificate of Occupancy—allowing you to focus on launching and growing your business.

What Is a Tenant Improvement?

A tenant improvement (TI), also known as a commercial build-out, is the renovation or construction required to customize a leased commercial space for a tenant's specific business.

Many commercial spaces begin as an empty shell with:

  • Concrete floors

  • Open ceilings

  • Minimal lighting

  • No interior walls

  • Limited plumbing

  • No finished offices

  • No reception area

Every business has different operational requirements.

A restaurant has very different needs than a law office, salon, medical clinic, fitness center, or retail store.

Our job is to transform that empty space into a professional, code-compliant facility designed around your business.

Change of Occupancy Specialists

Changing a commercial property's use often requires much more than cosmetic remodeling.

A former retail store becoming a restaurant—or an office converting into a medical practice—may require significant code upgrades.

These projects often involve:

  • Occupant Load Calculations

  • ADA Modifications

  • Additional Plumbing Fixtures

  • Exit Signage

  • Fire Alarm Upgrades

  • Accessibility Improvements

Our team works closely with architects, engineers, landlords, and local building departments to help move these projects efficiently through the approval process.
