Tips

  • Lyons' published fee schedule does not distinguish a separate commercial tenant-improvement rate from the general valuation-based Building Permit Fee schedule — confirm directly with SAFEbuilt for any project-specific fee estimate on a commercial scope.
  • Confirm fire-suppression/alarm requirements directly with the Lyons Fire Protection District early in design, since it is a separate special district from the Town Building Department and is not covered by the Town's own submittal checklists.
