Solar PV / ESS / EV
| Item | Status | Source |
|---|
| NEC solar (690/705/706) | Enforced via NEC 2020 in FBC 8th Ed. | ICC FLBC |
| Statewide solar permitting | FL promotes expedited residential PV permits (§553.793 F.S.) — many jurisdictions use automated/expedited permitting | Florida Statutes 553.793 |
| EV charger (NEC 625) | Via NEC 2020; FBC-EC has EV-ready provisions for some occupancies | FBC-EC 2023 |
Adoption model & precedence
- The Florida Building Code applies statewide. Local governments cannot adopt weaker technical amendments; local amendments must be more stringent, address local conditions, and be filed/justified per §553.73 F.S. (with periodic sunset).
- The AHJ = the local (city/county) building department enforcing the statewide FBC + any approved local amendments.
- Electrical: the NEC edition is set within the FBC — statewide, not by a separate board.
Major cities / counties with their own amendments
| Jurisdiction | County | Own code? | Key amendments | Building dept. |
|---|
| Miami / unincorp. | Miami-Dade | FBC + HVHZ | High-Velocity Hurricane Zone — stricter wind, product approval (NOA) | miamidade.gov/permits |
| Fort Lauderdale | Broward | FBC + HVHZ | HVHZ wind provisions | broward.org |
| Orlando | Orange | FBC | standard statewide FBC | orlando.gov |
| Tampa | Hillsborough | FBC | standard | tampa.gov |
| Jacksonville | Duval | FBC | standard | coj.net |
HVHZ (Miami-Dade + Broward) is the biggest Florida-specific wrinkle: enhanced wind-load, impact-resistance, and Miami-Dade Notice of Acceptance (NOA) product approvals. Structural/envelope only — does not change NEC/IECC editions.
FL-specific energy-code amendments beyond the 2021 IECC base (8th Ed., verified 2026-07-03)
- Lighting power density (Table C405.3.2, space-by-space method): FL's 8th Edition reduced several space-by-space LPD allowances below the base 2021 IECC values — do not assume the base-IECC space-by-space table applies unmodified in FL; confirm the FL-specific value.
- High-efficacy lamps/luminaires requirement tightened from 90% to effectively ALL permanently installed luminaires/lamps (with a narrow exception for lamps in kitchen appliances) — stricter than the base IECC's historical 90% threshold.
- Functional testing evidence for lighting control systems is now required before final inspection passes — a FL-specific procedural/inspection requirement layered on top of the base IECC control-functionality mandate.
AHJ fallback (when local adoption is unverified)
- State baseline that always applies: 2023 FBC 8th Ed. (NEC 2020, IECC 2021 base, IPC-based plumbing).
- Likely AHJ: city building dept if incorporated, else county.
- Action: confirm HVHZ applicability (Miami-Dade/Broward) and any local wind amendments with the building department.
Change log
- 2026-07-02 — created; verified 8th Ed. (2023) FBC, NEC 2020, IECC 2021 via ICC + floridabuilding.org.
- 2026-07-03 — added FL-specific energy-code amendments beyond the 2021 IECC base (reduced space-by-space LPD in Table C405.3.2, tightened high-efficacy lamp requirement to effectively all luminaires, added functional-testing-before-final-inspection requirement for lighting controls), verified via floridabuilding.org change-summary documents.
