Permitting a Heat Pump

Overview

The permitting process for replacing existing mechanical or plumbing units has expanded beyond like-for-like or emergency replacements. A Quick Permit can be obtained to replace existing equipment with more efficient units, including upgrading gas-fired equipment with heat pumps. Eligible replacements now cover mechanical units with an input capacity of 300 MBH or less and water heaters below 200 MBH. Additional information can be found on the Quick Permit webpage.  

The permitting process for installing new heat pumps has not changed. Either heat pumps in new construction, or new heat pumps where there previously was not a mechanical unit. For example, removing baseboard heat and installing a new heat pump unit.

You will have to apply using the Building Log application in E-permits.  Some things to consider:

  • You will be asked to provide mechanical and electrical drawings prepared by a professional engineer.
  • A zoning review will be required for exterior equipment in new locations.
  • A wastewater review will be required for ground mounted equipment in new locations.
  • A landmark review may be required if the building is an individually designated landmark or within a historic district.
  • A structural review will be required for new roof mounted equipment.

Frequently Asked Questions

Can contractors or building owners still pull a quick permit for emergency replacements?

Yes. Quick permits are still allowed for emergency replacements. Emergency replacement is not based on a timeline. An emergency replacement is allowed if only one piece of equipment is failing. This includes heating, cooling, or service water heating equipment, or a ventilation system. To use a quick permit, you must replace it with the same heating or cooling capacity, with no other alterations. If you need to replace more than one piece of equipment, it will not be considered an emergency replacement.

What are the requirements for historical buildings?

Section C501.5 of the Denver Energy Code explains how the Energy Code applies to historic buildings. The permitting process is the same. The Landmark Team with Community Planning and Development would review any exterior work.

Is the Electrification Feasibility Report required to get a permit?

The Electrification Feasibility Report is one of several options you can use. It is NOT required to pull a permit for heat pump equipment.
