Tips

  • Not every addition/remodel needs Planning Division review — the Town's guide says it depends on scope ('this permit may need to go through planning review initially') — confirm with the Community Development Coordinator (970-748-4012) before assuming either way.
  • Cosmetic interior work like cabinets, countertops, flooring, and interior paint is exempt from a building permit entirely in Avon — don't over-apply for a purely cosmetic scope.
