Required Documents

Submit these with your initial project package.

Always required

  • Construction Plans
    Plans showing generator installation, electrical connections, and fuel supply. Plans prepared by a Florida-registered architect or engineer carry that professional's seal. Plans prepared by a contractor or owner are accepted without a seal unless Florida law or the building department requires professional plans.
  • Equipment Specifications
    Manufacturer specifications for the generator including capacity, fuel type, and output rating
  • Electrical Load Calculations
    Electrical load calculations showing generator capacity relative to the loads it will serve
  • Site Plan
    Site plan showing generator placement, clearances, and fuel supply routing

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.

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. #01Generator disconnect, transfer switch, and labelingLife Safety

    Standby generator installation requires approved transfer switch, disconnect, and required labeling per NEC 702 / 445.

    NEC 445NEC 702NEC 230.82
  2. #02Grounding and bondingLife Safety

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

    NEC 250
  3. #03Plan review applicability (FBC 107.3.5 minimum criteria)Documentation

    Commercial standby/emergency systems fall under NEC 700/701/702 compliance. FCC performs this review only when the building department requires plan review or the client opts in.

    FBC-B 107.3.5

Items marked Conditional review scope are non-blocking. Per FBC 107.3.5, plan review isn't required for these scopes — FCC reviews them when the building department requests it or the client wants the extra set of eyes.
