Section 1

Required Documents

Submit these with your initial project package.

Always required

  • Electrical Plans
    Electrical plans for the installation. A licensed electrical contractor may prepare unsealed plans for a system it installs within the limits of F.S. 471.003(2)(h). Plans prepared by an engineer carry the engineer's seal.
  • Equipment Specifications
    Manufacturer spec sheet with the UL 9540 listing and kWh capacity
  • Installation Location Plan
    Plan showing the installation location and clearances

Courtesy screen

Courtesy screen on every plan review

Every plan FCC reviews receives a limited courtesy screen for the items below when they are reasonably visible in the submitted documents. If we see an apparent issue that could cause the plans to fail review by another agency, we will identify it as a Courtesy Comment. Courtesy Comments alone do not cause FCC to fail or return the plan set unless the same condition also creates a building-code compliance issue within FCC's review scope. The responsible agency makes the final determination—for example, Planning and Zoning for setbacks, lot coverage, use, and other lot-compliance matters. The absence of a Courtesy Comment is not approval of those separate requirements.

  1. #01Plan and document coordination

    Obvious clerical, title-block, sheet-index, permit-description, or cross-sheet inconsistencies visible in the submitted documents. A Courtesy Comment on these items does not cause FCC to fail or return the plan set unless the same condition also creates a building-code compliance issue within FCC's review scope.

    FBC-B 107.2.1
  2. #02Zoning and site coordination

    Apparent setback, lot-coverage, use, or site-dimension conflicts visible in the submitted plans that could cause the plans to fail Planning and Zoning review. Planning and Zoning makes the zoning and lot-compliance determination. The absence of a Courtesy Comment is not approval of those separate requirements.

  3. #03Floodplain coordination

    Apparent inconsistencies or missing coordination in flood-zone, design-flood-elevation, finished-floor, or flood-opening information shown on the plans that could cause the plans to fail floodplain review. The floodplain administrator makes the determination. The absence of a Courtesy Comment is not approval of those separate requirements.

  4. #04Fire-authority coordination

    Apparent separately reviewed fire alarm, sprinkler, hood-suppression, smoke-control, or similar coordination issues visible on the plans that could cause the plans to fail fire review. The fire marshal makes the determination. The absence of a Courtesy Comment is not approval of those separate requirements.

Section 2

Approval criteria for this project type

These are the building-code criteria FCC uses to determine the plan-review result. An unresolved item may be issued as a Required Correction and cause the plan set to be returned for correction.

ElectricalConditional review scope

Conditional review scopePlan review is not required for this scope under FBC 107.3.5. FCC reviews these items only when the building department specifically requires it, or the client opts in.
  1. #01Grounding and bondingLife Safety

    Grounding electrode, equipment grounding, and bonding per NEC Article 250.

    NEC 250
  2. #02Energy storage system listing and installationLife Safety

    The energy storage system must be listed to UL 9540 and installed per NEC Article 706, including its inverter connections and disconnecting means.

    NEC 706UL 9540
  3. #03Service size and load calculationCode

    Electrical service and feeder sizing supported by NEC Article 220 load calculation.
