Tenant improvement buildouts are one of the most common commercial construction projects in Florida — and one of the most misunderstood in terms of permit requirements, cost responsibility, and CO implications. Here's the complete picture.
You've signed a commercial lease. Or you're about to. The space needs work before you can open — new walls, new flooring, updated electrical, maybe a kitchen or a reception area.
This is a tenant improvement buildout — and it has specific rules, processes, and pitfalls that catch Florida business owners and landlords off guard regularly.
What a Tenant Improvement (TI) Actually Is
A tenant improvement is construction work done to a commercial space to make it suitable for a specific tenant's use. It can range from painting and carpet replacement (cosmetic TI) to full gut-and-rebuild (significant TI).
The scope of TI is typically negotiated in the lease. Common structures: - Turnkey: Landlord builds to spec, tenant moves in - TI allowance: Landlord provides a dollar allowance, tenant manages the buildout - As-is: Tenant takes the space in current condition and handles all improvements
Each structure has different implications for who pulls permits, who owns the improvements, and who is responsible if something goes wrong.
The Permit Requirement
Any tenant improvement buildout that involves structural changes, electrical, plumbing, HVAC, or changes to the building's fire protection system requires permits.
This includes things that might seem cosmetic: adding a partition wall (structural), installing a new lighting circuit (electrical), adding a sink in a break room (plumbing).
The question of who pulls the permits — landlord or tenant — should be addressed explicitly in the lease and the construction contract. The entity pulling the permits is the contractor of record and bears legal responsibility for the work meeting code.
The Change of Occupancy Issue
If the tenant's intended use is different from the existing Certificate of Occupancy for the space, a change of occupancy is required before the business can open.
A former office space (Business occupancy) becoming a fitness studio (Assembly occupancy) is a change of occupancy. A former salon becoming a food service establishment is a change of occupancy.
Change of occupancy triggers: - Full plan review for the new occupancy classification - Fire marshal review - ADA compliance evaluation - New Certificate of Occupancy
This process takes 6-12 weeks minimum in most Florida jurisdictions. If your opening date doesn't account for this timeline, you will not open on time.

The Food Service Buildout — Special Category
Converting any Florida commercial space to food service use is one of the most permit-intensive commercial projects:
- Building permit (commercial construction)
- Plumbing permit (grease traps, commercial kitchen plumbing)
- Electrical permit (commercial kitchen equipment loads)
- Mechanical permit (Type I or Type II hood systems)
- Fire marshal approval (suppression systems for cooking equipment)
- Health department plan review and approval
- DBPR license
Timeline from plan submission to opening: 3-6 months minimum. Budget accordingly.
Landlord Responsibilities vs. Tenant Responsibilities
Typically landlord's responsibility: - Base building structural systems - Building-wide HVAC (though tenant distribution may be tenant's) - Building electrical service to the tenant's panel - Base plumbing to the space - Exterior and fire protection system (base building sprinklers)
Typically tenant's responsibility: - Interior improvements within the space - HVAC distribution within the space - Electrical from tenant panel through the space - Plumbing within the space - Interior fire protection modifications required by tenant's layout
Read the lease carefully before you sign.
The CO — Don't Open Without It
Operating a business in Florida without a valid Certificate of Occupancy for the specific use is illegal. Code enforcement can close you down. Your business insurance may not cover incidents at a location operated without a valid CO.
Do not commit to a public opening date until you have the CO in hand.
