Steps
Scope the project across all applicable permit tracks: structural/building permit for the pergola or carport frame, electrical permit for the PV system, and (where the jurisdiction has a solar ordinance) a dedicated solar permit
Have a licensed engineer stamp structural calculations for the frame carrying panel dead load plus wind/snow load, since solar carports/pergolas are commonly flagged for missing engineering above a certain system size threshold
Coordinate utility interconnection approval in parallel with the building permit process, since final inspection typically requires both the AHJ sign-off and the utility's interconnection agreement
Confirm with the local planning department whether the solar pergola/carport is classified under residential accessory-structure rules (ancillary to the main building) or under separate vehicle-canopy rules, since clearance and drainage requirements can differ by classification
Sequence inspections correctly: footing/foundation, structural framing, electrical rough-in, then final inspection with interconnection approval
Known gotchas
Solar carports/pergolas get treated simultaneously as a structure, a solar installation, and sometimes a vehicle canopy; missing any one of the three permit tracks (building/electrical/solar) is a common delay cause
Utility interconnection approval and AHJ final inspection are separate approvals that both have to close out before the system can be energized; plan the timeline (commonly cited as 8-16 weeks total) around both, not just the building permit
