Tacoma panel replacement and residential service upgrades

Bring your Tacoma electrical panel replacement or service-upgrade plans to an independent electrician. We qualify the request and help coordinate the handoff, with Tacoma Power engineering and cutover steps included where it serves your home.

PLAN YOUR TACOMA PROJECT

Plan your Tacoma 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 Tacoma electrical permits?

Tacoma Power issues electrical permits and performs inspections for the Tacoma properties it serves.

  1. Use Tacoma Power’s electrical permit and inspection process for its service territory.
  2. Coordinate the inspection release with the utility’s separate engineering and connection work.
Permit jurisdiction reference

For Tacoma properties served by Tacoma Power, L&I directs electrical permitting and inspection to Tacoma Power. Confirm the utility account and exact project address before selecting the route.

02

UTILITY SERVICE & CONNECTION

How does utility work fit your upgrade?

Tacoma Power engineering reviews service changes and added loads; its crews handle authorized disconnect and reconnect work. Electrical inspection, engineering and crew scheduling are separate steps.

  1. Provide the planned loads and proposed service equipment for review.
  2. Coordinate the electrical inspection release and scheduled disconnect/reconnect.
  3. Confirm the project’s engineering review package directly; published Tacoma sources differ on some thresholds.
Service-area reference and requirements

Official Tacoma document states Tacoma Power serves Tacoma and University Place and parts of Lakewood and the Puyallup-area communities. 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.

Does Tacoma Power handle every step?

Tacoma Power handles electrical permits and inspections in its service territory, but engineering review and crew scheduling are separate functions. A contractor’s permit does not reserve a disconnect or reconnection.

  • The project plan should identify who submits each request, what Tacoma Power must approve before work, and what must be complete before service is reconnected.

What changes for a larger residential service?

Tacoma Power New Services Engineering determines available service sizes and locations and assesses utility facilities for added loads. A 400 amp request needs a complete equipment and utility scope.

  • Tacoma Power should confirm which engineering-review threshold applies to the actual project.
  • Use that review to define the estimate; an amp rating alone is not an approved design.
  • Tacoma Power publishes construction standards for meter sockets, meter-socket adapters, customer-owned generation, residential underground service boxes, overhead clearances, underground conduit and joint utility trenches.
  • Those standards are the utility-side reference when a panel/service change crosses the meter or service entrance.

What can affect the cutover plan?

A meter move, overhead-to-underground conversion, access route or easement can add utility dependencies. Tacoma Power prohibits unauthorized handling of meters, seals and service conductors.

  • The proposal should name disconnect and reconnection responsibilities and explain how inspection corrections or unfinished site work could delay service restoration.

What should you ask about an overhead-to-underground change?

Tacoma’s handbook directs owners to New Services Engineering before proceeding with that conversion. The utility’s approval and crew sequence matter alongside the contractor’s work; route, access and easements can also affect the project.

  • Ask for the customer site-work boundary and utility tasks in writing, including restoration and the readiness conditions for cutover.
  • This guide does not prescribe trenching or wiring methods; the utility and qualified contractor establish the approved design.

Tacoma housing-age context

64.3% of housing units were built before 1980: 62,605 of 97,298 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.
