Building Log permit path for heat pump conversion work
Denver CPD says replacing a gas-fired warm-air furnace, unitary AC, or gas-fired hot water heater with heat pump or partial dual-fuel heat pump equipment cannot be permitted as a Quick Permit. The project must use the Building Log application in E-permits, and Denver notes that mechanical and electrical drawings plus zoning, wastewater, landmark, or structural review may be required depending on the scope.
