Leasing a commercial space in Jacksonville? Turning that bare shell into a working storefront, office, or restaurant is called a commercial build-out (or tenant improvement) — and getting it right keeps your opening on schedule and on budget. Ofir Engineering is a licensed Florida general contractor (License #CGC 1540016) serving Jacksonville, Ponte Vedra, St. Johns, and Northeast Florida.

What Is a Commercial Build-Out?
A build-out, or tenant improvement (TI), is the interior construction that converts a vacant commercial shell into a finished, functional space — adding walls, electrical, plumbing, HVAC, flooring, lighting, and finishes for your specific use. It’s typically faster and less costly than ground-up construction.
What a Build-Out Includes
- Space planning and design to fit your operations and code.
- Demolition of existing partitions if needed.
- Framing, electrical, plumbing, and HVAC for the new layout.
- Flooring, ceilings, lighting, fixtures, and finishes.
- Signage coordination, final inspections, and certificate of occupancy.
Commercial Build-Out Cost and Timeline in Jacksonville
Because the shell already exists, build-outs cost less per square foot than ground-up work, with the range driven mostly by use and finish level (a basic office vs. a restaurant with a commercial kitchen). Timelines typically run 6 to 12 weeks, with permitting and long-lead equipment as the main variables. See our commercial construction guide for full cost context.

Permits for a Jacksonville Build-Out
Most commercial build-outs require permits through the City of Jacksonville, with plan review for life-safety, accessibility, electrical, and mechanical work. A licensed commercial contractor handles submission and inspections so you avoid delays.
Who Pays — Landlord or Tenant?
Build-out costs are often shared through a tenant improvement allowance negotiated in your lease. Knowing your real build-out cost before you sign helps you negotiate the right allowance — something we can help you scope early.
