1. Permitting & Zoning Process

The City of Lake Oswego utilizes a structured review process to ensure all EV charging installations meet safety and building standards.
Required Permits

EV charger installations require one of the following permit types:

  • Electrical Permit: Required for the wiring and installation of the charging unit. Residential electrical permits are available online in only a few minutes.
  • Commercial Structural Permit: May be required for non-residential installations involving structural modifications or specific mounting requirements.

Application & Review

  • Online Submittal: Licensed contractors should apply for permits online via the Oregon state portal at BuildingPermits.Oregon.gov.
  • Reviewing Departments: Applications are primarily reviewed by the Building Department. If the project involves significant site changes, the Planning Department may conduct a concurrent zoning review.
  • Review Timeline: Reviews are typically completed concurrently to expedite the process. Standard residential electrical permits are often issued quickly through the online portal.
  • Triggers for Additional Review: 
    • Zoning Review: Triggered for commercial installations that alter parking configurations or impact landscaping.
    • Discretionary Review: Triggered if the installation occurs on a site with specific design district requirements or historic preservation status.

2. Application Checklist

Ensure your application includes the following information to avoid delays. While not all of these items are required for residential projects, the following items are generally useful for approving EVSE projects:

  • Required Forms: Completed Electrical or Structural permit application forms.
  • Required Fees: Permit fees based on the current City of Lake Oswego fee schedule. 
  • Technical Specifications: Ideally, include manufacturer data sheets for the EVSE, including charging level (Level 1 or 2), amperage, and voltage.
  • Site Plans: A scaled drawing showing the location of the charging station, proximity to the electrical panel, and parking space layout.
  • Supporting Materials: Load calculations to ensure the existing electrical service can support the new EVSE load.
  • Accessibility: For non-residential projects, plans must demonstrate compliance with ADA and Oregon structural specialty code accessibility requirements.

3. Inspection Steps

Once the permit is issued and the equipment is installed, an inspection is required before the system is energized.

  • Request Inspection: Schedule via the BuildingPermits.Oregon.gov portal or contact the Building Department.
  • Site Access: Ensure the inspector has clear access to the electrical panel and the EVSE unit.
  • Final Approval: The inspector will verify that the installation matches the approved plans and meets local building standards.
