Tips

  • Mt. Crested Butte's mechanical permit fees are flat per-category charges ($50 per line item) set directly in the Town's ordinance — unlike the valuation-based Building Permit fee table, there is no scaling by project cost here.
  • If your mechanical work is part of a project already covered by a building permit, you may not need a separate standalone mechanical permit — confirm with the Building Division.
