Electrical service panel upgrades have become increasingly common as South Florida homeowners add electric vehicle chargers, solar systems, electric heat pump water heaters, and induction cooktops. Older 100-amp services are insufficient for modern electrical demand, and panel replacement triggers significant permit requirements.
This guide details electrical panel upgrade permits across Miami-Dade, Broward, and Palm Beach Counties, including coordination with FPL and other utilities.
WHEN PANEL UPGRADES ARE REQUIRED
Panel upgrades are typically necessary when: existing service is 100-amp or less and modern loads exceed capacity, EV charger installation requires dedicated 240V 50-amp or higher circuit, solar PV system installation exceeds service capacity, electric heat pump water heater or whole-home electrification, multiple appliance additions exceed available circuit positions, existing panel uses obsolete or recalled equipment (Federal Pacific, Zinsco, Sylvania), or evidence of overheating, burnt connections, or arc damage. Insurance carriers increasingly require panel updates for homes over 40 years old.
TYPICAL SERVICE SIZE OPTIONS
Modern residential service sizing options include: 100-amp service (insufficient for most modern South Florida homes), 150-amp service (adequate for older smaller homes with limited electrification), 200-amp service (current standard for most residential applications), 320-amp service or 400-amp service (required for larger homes, multiple AC units, EV chargers, or substantial solar installation), and 600-amp service (commercial and very large luxury residential). Service size is determined through electrical load calculation accounting for all major appliances and reasonable future expansion.
FPL AND UTILITY COORDINATION
Service panel upgrades require coordination with FPL or applicable utility: FPL notification before disconnection, possible meter relocation if existing location is non-compliant, possible service mast or weatherhead upgrade, transformer capacity verification (some areas require neighborhood transformer upgrades), and re-connection scheduling after panel installation passes inspection. FPL coordination typically adds 2 to 8 weeks to the project depending on scope and area capacity.
PERMITS REQUIRED
Electrical panel upgrades require: electrical permit covering the panel itself and any branch circuit modifications, building permit if the service mast or meter location moves, and utility re-connection authorization from FPL or applicable utility. Major service upgrades (400-amp and above) may trigger separate engineering review. Coordination with related permits (EV charger, solar, generator) is common since these often drive the upgrade decision.
TYPICAL PERMIT COSTS
Electrical panel upgrade permits in Miami-Dade County typically run $300 to $800 for the electrical permit alone. Building permits when required add $200 to $600. Broward County runs $250 to $700 electrical, $175 to $500 building. Palm Beach County runs $350 to $900 electrical, $225 to $650 building. Engineering review when required adds $500 to $2,000. Total installation cost (permits, equipment, labor) typically runs $2,500 to $6,000 for 200-amp service, $5,000 to $12,000 for 400-amp service.
APPROVAL TIMELINES
Electrical panel upgrade permits typically process within 1 to 5 business days in Miami-Dade County for standard residential upgrades. Broward County runs 1 to 4 business days. Palm Beach County runs 2 to 7 business days. Same-day permits are available in some jurisdictions through licensed contractor portals. FPL coordination and meter exchange adds 2 to 8 weeks beyond permit issuance to actual installation completion.
EV CHARGER INTEGRATION
EV charger installation increasingly drives panel upgrades: Level 2 chargers typically require 240V 50-amp dedicated circuit, Level 2 chargers for larger vehicles or faster charging require 60-amp or 80-amp circuit, multi-vehicle households may require multiple dedicated circuits, and load management systems can sometimes accommodate EV charging without panel upgrade. EV charger permits are typically included in the same submittal as the panel upgrade when both are happening simultaneously.
SOLAR AND BATTERY INTEGRATION
Solar PV systems require evaluation of existing panel capacity: solar interconnection requires a dedicated breaker space in the main panel, typical residential solar requires 25 to 50 amps of dedicated capacity, battery storage systems (Powerwall, Enphase) require additional electrical capacity, and whole-home backup capability typically requires service upgrade plus battery system. Planning panel upgrade and solar installation simultaneously reduces total cost.
