Tips

  • Mechanical permits are billed as a percentage (15%) of the Building Permit Fee in Avon, the same structure as plumbing — there is no separate standalone mechanical fee table.
  • Gas fireplace work may fall under a separate 'Fireplace Permit' category on Avon's own permit-types guide rather than the general mechanical/gas permit — confirm which category applies to your specific scope with the Building Division.
