Commercial electrical, where the building is older than the load.
Almost every commercial electrical problem in South Florida is the same problem wearing different clothes: a service sized for the loads of 1975, asked to carry the loads of 2026. Chargers, heat pumps, modern kitchens, life-safety equipment. The panel is not the bottleneck. The service is.
Academia holds its own Florida electrical license alongside its general contractor license. On commercial work that combination is the point — a service upgrade is rarely just electrical. It is a room, a riser, a slab penetration, sometimes a flood elevation problem. One licensed party carries all of it.
Florida is on the 2020 NEC — and that is newer than most buildings here have ever seen.
The Florida Building Code, 8th Edition (2023) took effect December 31, 2023, and it adopts NFPA 70, the 2020 National Electrical Code, through Chapter 27 of the Building volume. Florida does not adopt the NEC wholesale — it layers state amendments for wind zone, corrosion-resistant materials and coastal conditions on top, and those amendments carry the same force as the base code.
The previous code edition ran on the 2017 NEC. The jump is not cosmetic. Projects permitted from 2024 onward inherit provisions that simply did not apply to the building next door permitted in 2022:
- Surge protection at the service for dwelling units — NEC 230.67.
- Exterior emergency disconnect for one- and two-family dwellings, so first responders can kill power from outside — NEC 230.85.
- Substantially expanded GFCI scope under 210.8, and expanded AFCI coverage under 210.12.
- Article 625 for EV supply equipment and Article 706 for energy storage — both now enforceable Florida law rather than a design preference.
This is why “it was fine when it was built” and “it is compliant today” are different statements, and why a renovation that trips a permit threshold can pull a surprising amount of scope with it.
The 40-year recertification is an electrical inspection. Most owners think it is structural.
This is the single most commonly misunderstood item on this page, and it is worth money to understand it. Miami-Dade’s building recertification and Broward’s building-safety inspection program both certify a building as structurally and electrically safe. Electrical is not a footnote in these programs. It is half of them.
What the electrical inspection actually reaches — service type and size, whether protection is fuse or breaker, grounding, meter and electrical room clearances, every wiring method present in the building, branch circuits, feeders and their supports and mechanical protection, panels and gutters throughout, and equipment grounding. Broward’s program additionally reaches switchboards and motor control centers, disconnects, raceways, low-voltage and fire-alarm wiring, smoke detectors, generators, site wiring, pool and spa bonding, and the wiring feeding mechanical equipment.
Infrared thermography. Miami-Dade requires infrared thermographic inspection of electrical systems operating at 400 amperes or greater, performed with approved equipment by a certified technician. For most commercial and multifamily buildings that is not optional and not a line item to negotiate away — and every hot spot the scan finds converts directly into remediation scope with a deadline attached.
A written certification is due back to the building official inside a defined window from the notice, with an extension where repairs are required. Boards that treat the notice as a filing exercise and discover the electrical scope late are the ones that end up doing emergency work at emergency prices.
Worth separating clearly, because they are constantly conflated: the milestone inspection under Florida Statute 553.899 is structural only — electrical is not in it. County recertification is where the electrical obligation lives. Two different programs, two different scopes.
What owners are actually building.
Service capacity — the real project
A 1970s building was load-calculated for an era with window units, no EV, and modest kitchen loads. Put mini-splits in every unit, add chargers, add heat-pump water heating, and the original service is not close. Service and switchgear modernization is the most capital-intensive line item in South Florida commercial electrical work, and it is the one that determines whether every other upgrade on the wish list is even possible. It should be priced first, not last.
EV charging — and what a condo board may and may not do
Florida Statute 718.113(8) prevents a condominium declaration from barring a unit owner installing a charging station in their own limited common element parking space. The owner carries installation, operation, maintenance and insurance costs, and the electricity must be separately metered or measured. The association may impose reasonable safety and architectural requirements — it may not prohibit, and it may not make it prohibitively expensive. Separately, under 718.113(9), a board may install charging on common elements without the material-alteration vote that would normally be required. The practical bottleneck is almost never the charger. It is the service capacity above.
Solar and storage interconnection
FPL runs a tiered net-metering program: up to 10 kW AC at the first tier; 10–100 kW at the second, with an application fee and a liability-insurance minimum; and 100 kW to 2 MW at the third, with a higher fee, higher insurance minimum and Fast Track screening. Systems must be approved before installation and cannot operate in parallel until FPL sets a bi-directional meter, generation is capped relative to service capacity and historical consumption, and larger systems interconnect three-phase. Energy storage now falls under NEC Article 706, with NFPA 855 governing siting and separation on the commercial side. None of this is difficult — it is simply sequential, and projects that install before approval get to do it twice.
Electrical rooms and flood elevation
Most South Florida buildings put switchgear and meter banks at or below grade — garage, ground-floor mechanical room. New and substantially improved buildings in a flood hazard area must elevate service equipment to the design flood elevation. The trigger to watch is the FEMA 50 percent rule: once planned work exceeds half the building’s pre-improvement value, the floodplain administrator can require the building to come into compliance, and relocating an entire electrical room upstairs is an extraordinary cost that belongs in the feasibility conversation, not the change-order conversation.
What goes wrong, by the age of the building.
Main Service Upgrade
Your 1980s electrical room is one inspection away from becoming a violation.
Built before 1970
Ungrounded two-wire branch circuits are the norm, cloth and rubber insulation is decades past its service life and fractures when disturbed, and fuse panels invite the most dangerous legacy condition of all — over-fusing, where someone replaced a nuisance-blowing 15-amp fuse with a 25-amp one and the wiring behind it has had no real overcurrent protection since. Services of 60 to 100 amps were normal. Renovation in this stock is rarely a repair; it is a rewire, and it should be budgeted as one.
1965 to roughly 1973 — aluminum branch wiring
During the copper shortage of that period, solid aluminum was used for 15- and 20-amp branch circuits in a great many homes and small buildings, heavily in Florida tract construction. The failure mode is not the wire — it is the connection: aluminum creeps under the clamping pressure of a terminal, cycles thermally, and forms an oxide layer that raises resistance until the joint runs hot. It overheats without tripping anything.
The Consumer Product Safety Commission’s finding is precise, and precision matters here: homes built before 1972 and wired with aluminum branch circuits were found 55 times more likely to have one or more wire connections at outlets reach conditions the CPSC defined as “Fire Hazard Conditions” — cover-plate screws reaching 300°F, sparking, or charring of surrounding material. That is a finding about outlet connections, not a statement that the house will burn down.
The repairs CPSC recognizes as permanent are a complete copper rewire, a COPALUM crimp by a certified installer, or an AlumiConn connector. Wire-nut pigtailing is not among them — and it is extremely common in this market, which means a building can have been “repaired” and still carry the condition.
One distinction that saves owners real money: this is about solid aluminum branch-circuit wire of that era. Modern stranded aluminum alloy conductors used for service entrances and feeders are code-recognized, standard practice, and not a defect. “There is aluminum in the panel” is not a finding.
Legacy panels — what is documented, and what is folklore
We are careful here, because the internet is not. Federal Pacific Stab-Lok: a New Jersey court granted partial summary judgment in 2002 finding that the manufacturer knowingly distributed breakers that were not tested to the UL standard their label claimed. That is a consumer-fraud adjudication. It is not a recall — no U.S. recall of these panels has ever been issued. CPSC investigated in the early 1980s and closed the matter in 1983 without a recall, and has since clarified that the closure made no safety determination either way. Both halves of that are true and both get misquoted.
Zinsco and Sylvania panels carry a documented failure mode — breakers that can weld to an aluminum bus and fail to trip — but no recall and no judicial finding of the FPE kind. Challenger: the only recall covered roughly nine thousand GFCI breakers from a 1988 manufacturing window, affecting the ground-fault function; “Challenger panels were recalled” is a misreading of a narrow action.
What is practically true regardless of the legal record: Florida carriers routinely flag these panels on four-point inspections, and that is an underwriting practice rather than a code determination. If insurance is the problem, replacement is usually the answer — but you should know which of those things is driving the recommendation.
1990s and 2000s
Copper branch wiring throughout and 200-amp residential services as standard, so the failures here are subtler: GFCI and AFCI coverage far narrower than the 2020 NEC now requires, first-generation arc-fault devices with poor discrimination, no tamper-resistant receptacles, and — in coastal buildings — thirty years of accumulated corrosion at bus bars, lugs and neutral bars. That corrosion is the quiet one. Rising contact resistance generates heat at connections without ever drawing enough current to trip a breaker.
Coastal corrosion and water, at any age
Salt air drives corrosion inside enclosures, and the physics is unforgiving: resistance rises at a corroded joint, heat follows current squared, and the failure develops at a connection that no protective device is watching. Service entrances, panel bus, aluminum feeders landing on copper lugs, rooftop disconnects and sub-slab conduit that fills with water are the usual locations. After any flood, the industry guidance is blunt: submerged breakers, panels, meters and GFCIs are replaced, not dried out and re-energized.
Questions we actually get.
Is electrical part of the 40-year recertification?
Yes — it is half of it. Both Miami-Dade and Broward certify buildings as structurally and electrically safe. Miami-Dade also requires infrared thermography on systems at 400 amperes or greater.
Is electrical part of the milestone inspection?
No. Milestone inspections under FS 553.899 are structural. This is the distinction that catches most boards out.
Our building has aluminum wiring. Do we have to rewire?
It depends what kind. Solid aluminum branch-circuit wire from roughly 1965–1973 carries a documented connection-failure risk, and the repairs CPSC recognizes are a full rewire, COPALUM crimps, or AlumiConn connectors — not wire nuts. Modern stranded aluminum feeders and service conductors are standard and compliant.
Can our condo association refuse an owner’s EV charger?
Not outright. Florida Statute 718.113(8) prevents the declaration from prohibiting installation in the owner’s own limited common element space, at the owner’s cost and separately metered. The association can impose reasonable safety and architectural conditions. We are contractors, not counsel — have the association’s attorney review your specific documents.
Is a Federal Pacific panel recalled?
No. There has never been a U.S. recall. There is a 2002 New Jersey court finding of consumer fraud regarding UL testing claims, and a CPSC investigation closed in 1983 without a recall or a safety determination. Separately, many Florida insurers decline or surcharge these panels, which is often the practical reason to replace one.
Why does our panel run hot without tripping?
Usually corrosion at a connection. Resistance rises, heat develops at the joint, and the current never rises enough to trip the breaker. It is exactly what infrared thermography is designed to find.
Recertification notice on your desk?
Send us the notice, the engineer’s report, or the thermography findings. You will get a written scope that separates what the county requires from what is merely recommended — with the service-capacity question answered first, because it governs everything else.
