City guides in Mason County

Shelton

A city can cross county boundaries. The project address determines which local requirements apply.

ELECTRICAL PERMIT & INSPECTION

Who handles Mason County electrical permits?

Washington L&I is the electrical permit and inspection starting point in Mason County.

Match the project address to the permit authority, then coordinate its inspection release with the utility work.

Permit jurisdiction reference

L&I directs a property inside a listed city electrical-inspection program to that city, a property served by Tacoma Power to Tacoma Power, and other Washington jobsites to L&I. Confirm the exact jobsite before buying the electrical permit.

UTILITY SERVICE & CONNECTION

How does utility work fit your upgrade?

The electric provider on the account handles utility service changes; the inspection authority handles the electrical permit. Both processes belong in the upgrade schedule.

Identify the serving electric account and proposed equipment.
Include the utility’s required service application, meter review and connection steps in the scope.
Use the local procedure and official sources below for the utility-specific requirements.

Service-area reference and requirements

Mason PUD 3's official construction/remodeling page is a provider-specific Mason County electric-service source; it does not claim to cover every Mason County address. L&I separately lists Mason PUD No. 1 and No. 3, so the serving PUD must be verified by address.

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 does utility coordination affect a Mason County service upgrade?

PUD 3 requires an application for altered service/added load before a customer or electrician changes a panel, service type or electrical load. The application package includes building permit and State Electrical Inspector approval number, plot plan, deed/parcel number and marked parcel corners.

Its new-service process requires an application fee, plot plan, new address and building/inspection information, and its notice says the customer must notify PUD 3 after the L&I inspector approves the service.

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.
