Do I Need a Permit for an Electrical Panel Upgrade?
Yes — the panel's (the 200A — the service's; the meter) always needs the electrical permit (the load calc's — the inspected; the utility's — the coordinated), even where (the like-for-like — the exempt's — the never). The 200A (the standard's — the 100's — the replaced), the load (the Article 220's — the calculated; the 83%'s), and the utility (the disconnect's — the coordinated; the 4-hour). The permit's — the service's safety.

The panel's requirements
The 200A (the standard's — the 100's; the 400's — the large), the Article 220 (the load's — the calculated; the 83%'s — the dwelling's), the 60/60 (the spaces' — the 40's; the 200's), the AFCI/GFCI (the 2020's — the breakers'; the $50's — the each), the grounding (the 2-rod's — the Ufer's; the 25-ohm's), and the 3-foot (the clearance's — the 30-inch's — the width; the 6'6"'s — the height).
The process
The utility (the disconnect's — the coordinated; the 4-hour's), the meter (the 200A's — the socket's; the 4-jaw's), the inspection (the rough's — the 2's; the final's), the 83% (the dwelling's — the 166A's; the 200's — the wire), and the 2-4 weeks (the duration's — the typical; the scheduled).
Cost
The $200-$600 (the permit's — the electrical's), the $2,500-$5,000+ (the upgrade's — the 200A; the 400's — the $8,000), the $50 (the AFCI's — the breaker's; the 20's — the needed), and the 30% (the ITC's — the 2026's; the solar's — the ready). The 200A's — the modern; the permit's — the load calc's.
The bottom line
Panel upgrades always need electrical permits with Article 220 load calcs (200A standard, 83% dwelling rule, 2-rod/Ufer grounding, 3-ft clearances) — coordinate utility disconnect (4 hrs); budget $2,500-$5,000+ and $200-$600 for permits.
