Do I Need a Permit for an Electrical Panel Upgrade?
Yes — the panel's (the 200-amp — the 100's; the service's) always needs the electrical permit (the 200's — the amps; the inspected), even for (the 100-to-200 — the swap's; the meter's). The 200-amp (the 100's — the 42's; the spaces), the 42 (the spaces' — the 200's; the 100's), and the 3-foot (the clearance's — the 30-inch's; the 6.5's). The permit's — the 200-amp's safety.

The panel's requirements
The 200-amp (the 100's — the 42's; the spaces'), the 42 (the 200's — the 100's; the spaces'), the 3-foot (the 30-inch's — the 6.5's; the clearance's), the 30-inch (the width's — the 3's; the 6.5's — the height), the 6.5-foot (the height's — the 3's; the 30's — the width), and the 100-to-200 (the swap's — the $2,500's; the $5,000's).
Service and grounding
The 200-amp (the 2/0's — the copper's; the 4/0's — the aluminum's), the 2/0 (the copper's — the 200's; the 4/0's — the aluminum's), the 8-foot (the rods' — the 2's; the 6's — the apart), the 6-foot (the apart's — the 8's; the rods'), and the 25-ohm (the 2-rod's — the 8's; the 6's).
Cost and inspection
The $100-$300 (the permit's — the electrical's), the $2,500-$5,000+ (the 100-to-200's — the swap's; the 200's), the 200-amp (the 42's — the 100's; the inspected), and the 3-foot (the 30's — the 6.5's; the 3's — the clearance). The 200-amp's — the 42's spaces; the permit's — the 100-to-200's.
The bottom line
Panel upgrades always need electrical permits (200-amp/42-space typical, 2/0 Cu or 4/0 Al service, two 8-ft ground rods 6 ft apart, 30-in x 3-ft x 6.5-ft working clearance) — budget $2,500-$5,000+ and $100-$300 for permits.
