Overcoming Permitting Barriers for Rooftop Solar

A recent report by the Institute for Local Self-Reliance (ILSR) highlights how inconsistent and cumbersome permitting processes at the local government level hinder the adoption of residential rooftop solar. ​The new report Overcoming Permitting Barriers for Rooftop Solar in Minnesota breaks down how local governments often slow residential solar projects with cumbersome or confusing permitting rules.

Key Findings:

  • Dual Permit Requirements: Most Minnesota municipalities mandate both building and electrical permits for rooftop solar installations.​

  • Varied Approval Timelines: Permit approval durations vary significantly, with some local governments taking up to six weeks, while others process permits in under a week.

  • Instant Electrical Permits Unutilized Locally: The Minnesota Department of Labor and Industry offers instant electrical permit approvals, yet no local governments have adopted instant permitting systems.​

  • High “Soft Costs:” Permitting and related non-hardware expenses constitute over half of the total costs for residential solar projects.​

Recommendations for Improvement:

  • Adopt Instant Permitting Platforms: Implementing automated systems like SolarAPP+ can expedite approvals and reduce administrative burdens.​

  • Provide Clear Documentation: Offering straightforward guidelines and checklists can streamline the application process.​

  • Enable Online Permitting: Transitioning to digital applications and payments can enhance efficiency for both applicants and municipal staff.​
