Tips

  • Commercial plan review timing depends on project size and complexity per the county's Building Department FAQ — the general 7-10 business day estimate is a floor, not a ceiling, for larger commercial projects.
  • Cell towers are exempt from building permitting as of May 8, 2025 (per 2024 IBC exemption M #4), EXCEPT for electrical services, which still require Wyoming-Design-Professional-stamped, site-specific electrical plans.
  • Coordinate final inspections with Planning staff on commercial projects to ensure site plan, grading, and Certificate of Review requirements are all satisfied together.
