Do You Need a Permit for a Commercial Tenant Improvement in Florida?

If you're opening a restaurant, fitting out a retail space, or renovating office interiors in Florida, the answer is yes — a permit is required. Commercial tenant improvement (TI) work in Florida — also called a buildout, fit-out, or interior renovation — almost always requires permits under the Florida Building Code, regardless of the size of the project. There is no dollar-threshold exemption for commercial work. The $7,500 residential permit exemption created by Florida HB 803 applies only to single-family residential properties; commercial tenants and property owners cannot use it.

What Is a Commercial Tenant Improvement Permit?

A commercial tenant improvement permit covers construction or renovation work performed inside a leased or owned commercial space — office buildings, retail centers, restaurants, medical offices, warehouses, and other non-residential properties. The permit allows the building department to verify that the work meets the Florida Building Code (8th Edition, 2023), life safety requirements, the Florida Fire Prevention Code, and applicable local amendments before occupancy. Without a permit and a final certificate of completion, you cannot legally occupy the finished space for commercial use.

What Commercial Buildout Work Requires a Permit in Florida?

Most interior work beyond cosmetic changes requires a permit. Here's how to think about the threshold:

• Always requires a permit: New walls, partitions, or framing changes; structural modifications; ceiling height changes; moving or modifying doors and windows; any work on plumbing, electrical, or HVAC systems; adding or relocating restrooms; installing a grease trap; fire suppression or alarm system work.
• Generally does not require a permit: Painting and wallcovering; replacing carpet or flooring in-kind on a flat slab; hanging signs, art, or display merchandise; replacing light fixtures in-kind without electrical modifications.

When in doubt, contact the local building department before starting. Starting work without a permit can result in stop-work orders and double fees — neither of which is welcome during a tight lease build-out timeline.

How Many Permits Does a Typical Commercial Buildout Need?

Most commercial tenant improvements require a building permit plus separate trade sub-permits. The building permit covers the structural and architectural scope. Trade permits are issued separately for each licensed trade:

• Electrical permit: New panels, circuits, outlets, lighting, and low-voltage systems
• Plumbing permit: New or modified drain lines, supply lines, restrooms, sinks, and grease interceptors
• Mechanical (HVAC) permit: New air handlers, duct modifications, exhaust hoods, and ventilation systems
• Fire review: Any fire sprinkler modification, fire alarm change, or kitchen hood suppression system requires review and approval by a certified fire inspector in addition to the standard plan review

A restaurant buildout — one of the most complex commercial TI projects — routinely involves all four trade permits plus fire review, and often a gas permit if cooking equipment runs on natural gas or propane. Budget extra time and fees for fire review in every Florida county.

How Much Does a Commercial Tenant Improvement Permit Cost in Florida?

Commercial TI permit fees in Florida vary by county and project scope. Based on regional data from Florida permit offices and permit consultants, typical ranges are:

• Building permit (base fee): $500 to $2,500+ depending on project value
• Plan review fee: Typically 50–65% of the base permit fee
• Trade permits (per trade): $50 to $500 per jurisdiction
• Fire review: $150 to $1,000+ depending on scope and jurisdiction

Total permit-related costs for a mid-size commercial TI often run $1,500 to $5,000 or more — separate from design fees, contractor costs, and construction. Counties with higher construction values, like Miami-Dade County and Broward County, tend to carry higher permit fees than smaller markets. For a broader look at permit fee structures across Florida, see our Florida building permit costs guide.

Under HB 803, effective July 1, 2026, local governments must limit inspection fees to actual costs and reduce permit fees when a Florida-licensed private provider handles plan review or inspections. If your commercial project uses a private provider under Florida Statute 553.791, the building department's fees are reduced accordingly — a useful option for projects where speed matters.

What Documents Does a Commercial TI Permit Application Require?

Commercial permit applications in Florida are more document-intensive than residential projects. Plan on assembling:

• Construction drawings signed and sealed by a Florida-licensed design professional — typically an architect or engineer — for any structural, mechanical, or complex scope
• Site plan showing the location of the tenant space within the building or center
• Energy compliance documentation (Florida Energy Code COMcheck or equivalent) for HVAC and lighting modifications
• Notice of Commencement — required for projects exceeding $2,500 to $5,000 (varies by county); must be recorded with the county clerk before construction begins
• Contractor license documentation — all contractors must hold active Florida DBPR state licenses; some counties also require local registration. Review our guide on how to verify a Florida contractor license before hiring.
• Business tax receipt (local occupational license) — required by many Florida municipalities as part of the permit application package

How Long Does Commercial Permit Review Take in Florida?

Commercial plan review in Florida takes longer than residential review because multiple departments — building, zoning, fire, and sometimes health or environmental — each review the same set of plans. Typical timelines:

• Simple TI (lighting, minor partitions, no trade work): 5–15 business days
• Mid-complexity TI (restroom addition, duct modifications): 3–6 weeks
• Complex TI (restaurant buildout, medical office, structural changes): 6–12 weeks or more

Large counties including Hillsborough County, Orange County, and Pinellas County accept commercial applications electronically and offer online portal tracking. Submitting complete, sealed plans on the first attempt is the single biggest factor in reducing review time — incomplete submittals that cycle back for corrections are the most common cause of delays on commercial TI projects.

Work cannot legally begin until the permit card is posted on site. Inspections must be scheduled and passed in sequence — later trade rough-ins cannot proceed until the prior inspection is approved. The building department issues a Certificate of Completion after the final inspection passes, which authorizes occupancy of the commercial space.

What Happens If You Skip the Permit for a Commercial Buildout?

Opening a commercial space without a permit is a serious code violation. Without a certificate of completion, the building department has no record that the space is safe to occupy. Code enforcement can issue a stop-work order or cease-and-desist after you've opened for business, forcing a closure and requiring you to expose completed work for retroactive inspection. Insurance coverage for incidents involving unpermitted work — fires, injuries, water damage — may be denied. And when you eventually vacate, an unpermitted buildout can become a liability issue with the property owner or an obstacle to the next tenant's permit.
