Do I need a permit for hvac replacement or installation in Littleton?
Yes. In Colorado, hvac replacement or installation generally requires a permit, and Littleton is no exception.
Littleton issues mechanical permits through eTRAKiT and enforces the 2024 International Mechanical Code and 2024 International Fuel Gas Code. Furnace or AC changeouts and gas line work are inspected by the city building division. Confirm mechanical submittal items with the Littleton Building Division. Most Colorado jurisdictions require a mechanical permit to change out a furnace, air conditioner, or heat pump, even for a like-for-like swap; the exact permit type and inspections depend on the locally adopted code. Gas piping and electrical connections for the equipment fall under Colorado's state Plumbing and Electrical Boards and may require their own state permits in addition to the local mechanical permit.
