After a hurricane, gasoline is usually still in the ground at Florida stations. What is missing is the electricity to pump it. That is exactly the problem Florida Statutes §526.143 was written to fix after the 2004–2005 hurricane seasons, when drivers on evacuation routes found station after station dark and dry.
This guide covers who the law applies to, what "generator-ready" actually means, the portable-generator fleet rule for multi-site owners, the paperwork inspectors ask for, and the penalties — in plain language, for the person who owns or runs the station.
Who must comply — the four groups
§526.143 does not treat every station the same. It creates four distinct obligations:
| Facility | Trigger | What §526.143 requires |
|---|---|---|
| New or renovated retail outlet | Certificate of occupancy issued on or after July 1, 2006 (new build, or renovation that raised assessed value by more than 50%) | Pre-wired with an appropriate transfer switch; capable of operating all fuel pumps, dispensing equipment, life-safety systems, and payment-acceptance equipment on alternate power |
| Outlet near an evacuation route | Within one-half mile of an interstate highway or a state or federally designated evacuation route, and at or above the fueling-position threshold for the county (table below) | Same pre-wiring and operating capability as above |
| Owner of 10+ outlets in one county | Ownership count, regardless of station age or location | Keep at least one portable generator for every 10 outlets, stored in Florida or within 250 miles, deployable within 24 hours after a major disaster |
| Motor fuel terminal or wholesaler | Sells motor fuel in Florida | Distribution loading racks operable on alternate power for at least 72 hours; the power source available within 36 hours after a major disaster |
Exemptions in subsection (4): automobile dealers, fleet operators, outlets that sell fuel exclusively to their own fleets, and outlets with a written agreement to receive alternate power from a public hospital.
The half-mile evacuation-route rule
The most common question is whether an existing, never-renovated station is caught by the law. It is only if it sits within one-half mile of an interstate or a designated evacuation route and is large enough:
| County population | Fueling positions that trigger the requirement |
|---|---|
| 300,000 or more | 16 or more |
| 100,000 to 300,000 | 12 or more |
| Under 100,000 | 8 or more |
A "fueling position" is generally counted as each spot where one vehicle can fuel at the same time — a dispenser serving both sides counts as two positions. The statute does not define the term in the section itself, so if your station is near a threshold, confirm the count with your county emergency management office before assuming you are exempt.
Evacuation-route designations come from the state. Check your route status with the Florida Division of Emergency Management or your county emergency management director — do not guess from road signage alone.
What "generator-ready" actually means
For most retail outlets, §526.143 is a wiring and capability law, not a "buy a generator" law. Compliance has three parts:
- Transfer switch, professionally installed. The wiring and transfer switch must be installed by a Florida certified electrical contractor. This is explicit in the statute — a handyman hookup does not comply.
- Full-load capability. On alternate power, the station must be able to run all fuel pumps (including submersible turbine pumps), dispensing equipment, life-safety systems (emergency lighting, leak detection, emergency shutoff), and payment-acceptance equipment. A generator that runs the pumps but not the point-of-sale system does not meet the standard, because a station that cannot take payment cannot sell fuel.
- Verified at inspection. For new and renovated outlets, the local building inspector checks the equipment and its operation before issuing the certificate of occupancy. Failing this check means no CO.
How you supply the actual power is your choice: a permanently installed standby generator, an owned portable unit with a documented connection point, or a rental arrangement. In practice, a permanent standby set is the only option that does not depend on post-storm logistics — rental fleets are typically spoken for within hours of a landfall, and a portable stored off-site competes with every other user on the road. Gas-fueled standby sets in the 30–60 kW class (for example, Cat Olympian OG-series units running on the station's piped natural gas or on-site LP) cover a typical full station without diesel refueling runs.
The 10-outlet portable fleet rule
If one entity owns 10 or more retail outlets in a single county, subsection (5) requires:
- One portable generator per 10 outlets, plus one more for any remainder above a multiple of 10. Sixteen outlets means two generators; twenty-one outlets means three.
- Storage in Florida or within 250 miles of the outlets they serve.
- Availability within 24 hours after a major disaster.
Alternative: entities with 10 or more outlets in a single domestic security region may instead hold a written reciprocal agreement with a similarly equipped entity for generator access. Payment for the shared units is permitted, but the agreement must be in writing — a phone-call understanding with a neighboring chain does not comply.
Testing and records
The statute requires facilities to keep, and produce on request:
- Documentation of the transfer switch installation by a certified electrical contractor.
- A written attestation of periodic testing and of the operational capacity of the alternate power system.
These records must be available to the Florida Division of Emergency Management and to the county emergency management director on request. §526.143 does not set a test interval, so "periodic" is what you can defend after a storm. A sensible baseline is the NFPA 110 habit — monthly exercise under load, with dated log entries. See our guide to NFPA 110 generator testing requirements for the full cadence.
Penalties and enforcement
Chapter 526 is enforced by the Florida Department of Agriculture and Consumer Services (§526.09), with the Department of Legal Affairs and state attorneys assisting. Penalties come from §526.11:
| Violation | Classification | Exposure (per §§775.082–775.083) |
|---|---|---|
| First violation | Second-degree misdemeanor | Up to $500 fine and up to 60 days |
| Second or subsequent violation | First-degree misdemeanor | Up to $1,000 fine and up to 1 year |
The more immediate lever for a new or renovated station is administrative: the building inspector will not issue a certificate of occupancy without the wiring and transfer switch in place.
Compliance checklist
- Pull the certificate-of-occupancy date for the site. On or after July 1, 2006 (including a renovation that raised assessed value by more than 50%) means the pre-wiring rules apply.
- Measure the distance to the nearest interstate or designated evacuation route. Under half a mile, count your fueling positions against the county-population table above.
- Confirm route designations and position counts with the county emergency management office.
- Have a Florida certified electrical contractor install (or certify) the transfer switch and wiring; keep the installation documentation on file.
- Verify the backup source actually carries the full required load: pumps, dispensers, life-safety systems, and payment equipment, all at once.
- Test periodically and sign a written attestation after each test; file it where a manager can produce it for FDEM or the county.
- If you own 10+ outlets in one county: do the portable-generator math (1 per 10 plus remainder), confirm storage within 250 miles, and document the 24-hour deployment plan — or execute a written reciprocal agreement.
- Recheck your status after any renovation, dispenser addition, or change in evacuation-route designations.
Common questions
Are gas stations in Florida required to have a generator?
Not all, and for most covered stations the law technically requires generator readiness — transfer switch, wiring, and the capability to run on alternate power — rather than a permanently installed unit. The exceptions are owners of 10 or more outlets in one county, who must physically keep portable generators, and terminals, which must be able to run loading racks for 72 hours. Many operators choose a permanent standby set anyway, because readiness without a guaranteed power source fails exactly when it matters.
What size generator does a gas station need?
Most stations land between 20 and 60 kW. The load includes submersible turbine pumps (usually the largest motor loads, and their starting current drives the sizing), dispensers, canopy and store lighting, POS and network equipment, coolers and freezers, and fuel-management systems. If you want a quick, load-by-load starting point, use our sizing tool with the gas-station profile.
Does a rental contract satisfy §526.143?
The statute requires the station to be "capable of operating" on alternate power and requires documentation and testing attestations — it does not name rentals one way or the other for individual outlets. A documented rental arrangement plus installed transfer switch is a common reading, but availability after a regional storm is the practical weakness. Confirm your specific setup with your county emergency management office and FDACS before relying on it.
What counts as "substantially renovated"?
The statute defines it as a renovation that increases the assessed value of the outlet by more than 50%. If your remodel is anywhere near that line, ask the county property appraiser and building department before pulling permits — crossing it triggers the full pre-wiring requirement at CO.
Who checks compliance, and when?
Local building inspectors verify the wiring and transfer switch before issuing a certificate of occupancy for new or renovated outlets. After that, the Division of Emergency Management or your county emergency management director can request your installation records and testing attestations at any time, and FDACS enforces the chapter. The most common failure found after storms is paperwork: a switch exists, but no one can produce a signed testing attestation.
