Seattle electrical panel replacement & service upgrades

Request electrical panel replacement or a service-upgrade estimate in Seattle. We qualify the work and help coordinate an independent electrician, with scheduling and handoff support. Bring any Seattle City Light service-change requirements into the estimate.

PLAN YOUR SEATTLE PROJECT

Plan your Seattle electrical upgrade.

Choose the work you have in mind. Get the scope questions and a planning checklist, then send a request when you are ready.

Get an estimate for the panel work you need.

Have the electrician document the existing equipment and explain the replacement. The work may retain your current service capacity; separate any meter or utility-service changes in the estimate so you can compare the same scope.

Bring charging and heating into one electrical plan.

Share the charger specifications, heat-pump requirements and other planned loads with the electrician. A load calculation and suitable load-management options help establish the work your home needs before you commit to a larger service.

Compare a complete 200 or 400 amp project.

A larger panel label alone does not establish available service capacity. Ask the electrician to connect your load assessment with the meter equipment, conductors, utility requirements and inspection handoff, so the proposed upgrade covers the whole job.

Plan for the loads you want to keep running.

Tell the electrician what you want backed up and whether the system will operate in parallel with utility power. Generator transfer equipment, solar and batteries have different connection requirements; put the applicable utility review in the plan before installation.

ELECTRICAL PERMIT & INSPECTION

Who handles Seattle electrical permits?

Seattle issues electrical permits and performs electrical inspections inside its city limits.

  1. Use the Seattle electrical permit and inspection process.
  2. Keep the permit number and inspection release with the service-upgrade work order.
Permit jurisdiction reference

L&I lists Seattle as a city that issues electrical permits and performs inspections inside its city limits. Confirm the jobsite is in that city program before purchasing the permit.

02

UTILITY SERVICE & CONNECTION

How does utility work fit your upgrade?

Seattle City Light reviews new or upgraded service applications and coordinates its utility connection work. The electrical permit and inspection are handled separately by the jobsite’s inspection authority.

  1. Submit the service application with the electrical permit number.
  2. Include the site plan, one-line, load information and other drawings the project requires.
  3. Complete the municipal approval and City Light inspection steps before utility connection work.
Service-area reference and requirements

Official Seattle City Light page describes City Light delivery service in its service area; Seattle is the named municipal context. Confirm the electric account and service address before applying a provider’s requirements.

Confirm the provider for the exact address; city boundaries and electric-service boundaries can differ.

Coordinate the permit and utility steps in the same project plan, so the installation and reconnection can move in sequence.

How is electrical panel work permitted in Seattle?

Seattle is a current city electrical-permit jurisdiction. A permanent City Light connection requires the electrical permit number and local municipal approval, followed by the jurisdictional inspection and City Light inspection sequence.

What changes the electrical service-work plan in Seattle?

Seattle City Light's service-application guidance covers existing-service alterations/removals and new permanent or temporary service. The application can require a legal/electrical site plan, one-line riser, load calculations, building elevation and vault plans; the 2026 Standards for Electric Service is the current standards entry point.

What should a panel replacement estimate in Seattle include?

A complete Seattle panel replacement estimate identifies the equipment, circuit work, service capacity, permit holder and final inspection records. Meter and utility connection work should be priced separately from a panel-only replacement.

  • Confirm the serving utility for this King County address.
  • Include the load-review basis and the equipment you want to add.
  • Identify restoration, utility charges and inspection closeout in the written scope.

Seattle housing-age context

52.8% of housing units were built before 1980: 207,857 of 393,918 housing units. 2024 ACS 5-year estimates; universe: total housing units.

Calculation and uncertainty

Calculation: (B25034_007E+B25034_008E+B25034_009E+B25034_010E+B25034_011E)/B25034_001E. Variable: B25034 (year structure built). The derived share margin of error was not propagated. Source component and total margins of error are retained in the research data; this share is an estimate.

Building age does not establish electrical-panel condition or a need for replacement. Equipment condition and the planned work need their own assessment.
