Introduction

Tri-Cities, Washington homeowners considering rooftop or ground‑mounted solar must navigate local permit rules, utility interconnection, and incentive programs administered by city building departments and local utilities. This guide explains typical permit steps, documentation, inspections, and where to find official forms in Kennewick, Pasco, and Richland. It highlights compliance points, enforcement pathways, and practical next steps so you can plan installations that meet municipal bylaws and interconnection rules.

Permits & Typical Steps

Most solar installations require a building permit and an electrical permit from the city where the property is located. Common steps include plan preparation, permit application, third‑party plan review (if applicable), scheduling inspections, and obtaining final approval.

  • Prepare site plan, equipment cut sheets, and single‑line electrical diagram.
  • Submit building and electrical permit applications to the local city permit center.
  • Provide installer license and product approvals as required by the city.
  • Schedule required inspections after installation stages: structural, electrical rough, and final.
  • Pay permit fees and any plan review fees set by the city.
Start permit conversations with your local building department early to avoid rework.

Interconnection & Utility Steps

After permit issuance, coordinate with your electric utility for interconnection and net metering or crediting. Utility requirements and incentive programs vary; confirm requirements with your local utility and follow their interconnection application process.Benton PUD solar information[1]
