A St. Petersburg panel replacement: hand-labeled old breakers, then the new panel with every circuit labeled.

The oldest panels in Pinellas County

St. Petersburg is the county’s largest city, with about 262,700 residents, and it has the oldest housing. The median home was built in 1969 (Census ACS 2020–2024), and in neighborhoods like Historic Kenwood, Old Northeast, Crescent Lake, Old Southeast and Roser Park, many houses date to the 1920s. That shows up at the panel:

Fuse boxes. Still in service in some pre-war bungalows and mid-century homes, often with oversized fuses screwed in to stop nuisance blowing, which defeats the protection entirely.
Federal Pacific (Stab-Lok) and Zinsco panels. Common in homes built in the 1950s through the ’70s in areas like Disston Heights, Jungle Terrace, Euclid–St. Paul, Tyrone and Lakewood Estates. Both have well-documented breaker reliability concerns. More on FPE & Zinsco →
60- to 100-amp services that were never meant to run central AC, a modern kitchen and an EV at the same time.
Exterior panels worn out by weather, with faded labels, rusted covers and loose wiring around them.
Panels in closets and bedrooms of older homes, sometimes in spots that wouldn’t meet today’s working-clearance rules.

Many Florida insurers won’t renew a policy on a home with a fuse box or a flagged panel brand, and 4-point inspections call them out. If that’s why you’re here, send us the report.

A recent St. Pete panel replacement

On one St. Petersburg job, the home’s exterior panel had breakers labeled by hand in marker, a printed label that had faded and peeled away, and loose wiring and old equipment on the wall around it. We replaced it with a new panel mounted beside the meter, ran the wiring in conduit, labeled every circuit, and left a clearly marked service disconnect. See the before and after →

Flood-exposed panels after Helene and Milton

Hurricane Helene’s surge in September 2024 put saltwater into homes in Shore Acres, Snell Isle, Venetian Isles, Riviera Bay and other low-lying neighborhoods along Tampa Bay and Boca Ciega Bay, and Hurricane Milton followed with wind damage and long outages. If your panel, meter or breakers were under water:

Don’t re-energize them. Saltwater-exposed breakers and bus bars usually have to be replaced. Corrosion keeps working inside the equipment after it looks dry.
Expect a permit and an inspection before Duke Energy reconnects in many cases. We handle both.
Raising equipment may be required. If your home is being substantially improved or rebuilt after storm damage, flood rules may require the panel and other electrical equipment to sit above a set elevation. We check this with you before quoting, and it’s often the right time to move an interior panel to a better location.

If you’re dealing with a wet panel right now, call our 24/7 emergency line for St. Pete.

Breaker replacement or a full panel upgrade?

Not every problem needs a new panel. If your panel is a sound, current brand with clean bus bars, we can often replace a worn breaker or add the AFCI/GFCI breakers your home needs. We recommend a full upgrade when:

It’s a fuse box, Federal Pacific, Zinsco or another brand where replacement breakers don’t fix the underlying risk
The bus bars are burned, pitted or corroded, including from flood exposure
Replacement breakers are obsolete or hard to find
There’s no room for the circuits you need

Panel, service upgrade or rewiring?

In older St. Pete homes, the panel is often one piece of a bigger picture. We’ll tell you plainly which of these you need:

A new panel on your existing service, when the service is big enough.
A service upgrade, when a 60- or 100-amp service can’t carry the home. That means a larger meter base and service conductors, coordinated with Duke Energy.
Rewiring, when the house still has knob-and-tube, cloth-insulated or ungrounded circuits. A new panel doesn’t fix old wiring behind the walls. If a full rewire isn’t in the budget right now, we’ll give you a phased plan.

Want circuit-level monitoring and control from your phone? A SPAN smart panel replaces your panel entirely. See SPAN in Snell Isle & Old Northeast. We’re a SPAN Authorized Installer with 20 SPAN installs. Solar and batteries are installed by our licensed partner installers; we do the electrical work and manage the project.

Permits in St. Petersburg

Inside city limits: City of St. Petersburg Building & Permitting, Municipal Services Center, One 4th Street N.
Local historic districts: interior panel work is a standard electrical permit, but moving or adding equipment on a street-facing exterior wall may need additional review. We plan for it.
Unincorporated addresses with a St. Petersburg mailing address, including parts of Lealman and Tierra Verde: Pinellas County.
Utility: Duke Energy Florida.

A panel replacement always needs a permit. Unpermitted panel work can cause problems with insurance claims and when you sell.

What a St. Pete panel upgrade includes

Site visit. Panel, meter, grounding and bonding, the wiring at the panel, and what you plan to add.
Itemized quote after the site visit. Every part of the job on its own line. No panel prices over the phone.
Permit and Duke Energy coordination.
Installation, usually in one day for a straight swap. Relocations and service upgrades take longer. Every circuit is tested and labeled on a printed directory.
Whole-house surge protection at the panel. The electrical code adopted in Florida requires it when a home’s service equipment is replaced.
Inspection. We schedule it and meet the inspector.

See our Good and Best panel options.

Hurricane season notes for this area

October is still hurricane season on the Gulf coast. For planned electrical work we keep the advice practical:

Standby generators need a listed transfer switch ahead of the panel. Portable-generator interlocks are a different product and are not installed in a SPAN Panel. See generator installation and hookups.
Whole-house surge protection is required by Florida’s adopted electrical code whenever a home’s service equipment is replaced, and it’s a smart add-on before storm season even when you’re not upgrading. See whole-house surge protection.
After a storm: do a visual check before restoring power if the house took on water, if you smell burning, or if the meter can or panel was submerged or damaged. Call us for a post-storm inspection rather than flipping the main back on and hoping. Emergency calls are answered 24/7; we do not promise a response time.
Permits: generator hookups, panel and service work still need the correct city or county permit. We pull those when we do the work.

Warranty, financing and scheduling

3-year workmanship warranty, extended to 5 years for Member Care Plan members.
Financing available through Acorn Finance, subject to credit approval. Check your options without affecting your credit score. Ask us and we’ll include the financing link with your itemized quote.
Hours: office 7 AM–5 PM, weekend service, and 24/7 emergency calls.

St. Petersburg panel upgrade FAQ

How much does a panel upgrade cost in St. Petersburg? It depends on the panel, your service size, the condition of the meter base and grounding, whether the panel needs to move, and any flood-related requirements. We give you an itemized quote after a site visit.

My insurer won’t renew because of my fuse box. How soon can you replace it? Call us with the inspection report or the insurer’s letter. We’ll schedule a site visit, give you an itemized quote, and pull the permit once you approve it. After the final inspection we can give you the documents your insurer asks for.

My panel was in the storm surge. Can it be cleaned and reused? Usually not. Saltwater-exposed breakers and panels are normally replaced. Leave the power off until it’s evaluated.

Do I need a service upgrade too? Only if a load calculation says so. Many St. Pete homes on 100-amp or smaller services do need one when they add central AC, an EV or a big kitchen, and we’ll show you the numbers.

My house is in a historic district. Can I still replace the panel? Yes. Interior panel replacements are standard permits. Exterior changes on a street-facing wall may need extra review, and we’ll plan the location with that in mind.

Who issues panel permits in St. Pete? The City of St. Petersburg inside city limits, and Pinellas County for unincorporated addresses. We pull the permit either way.
