What's Required in Washington

  • Work must be performed by a DC-licensed Master Electrician.
  • Must specify the amperage (e.g., 100A to 200A upgrade).
  • Circuit directory must be clearly labeled.

  • Grounding and bonding to water/gas lines must be verified.
  • Arc-Fault (AFCI) protection required for modern code compliance.

Do You Need a Permit to Upgrade an Electrical Panel in Washington?

Yes — panel work is one of the least optional permits in Washington. Replacing or upgrading an electrical panel involves the service equipment for the whole house, so the city wants an inspection on the other side of it. Permit fees typically run $100–$250 through the Department of Buildings. Expect the work itself to be restricted to licensed electricians here. An unpermitted panel is also one of the first things home inspectors and insurers flag, so the permit protects the resale, not just the wiring.

Upgrading From 100 to 200 Amps in Washington

The classic project is moving from a 100-amp to a 200-amp service to feed an EV charger, heat pump, or induction range. In Washington that's a permitted service upgrade like any panel change: permit, inspection, and a licensed electrician doing the work. Because the utility's service connection is involved, plan for coordination with your power company on disconnect and reconnect timing. Inspectors typically verify grounding and bonding, working clearances around the panel, and a properly labeled circuit directory before signing off.
