Do I need a permit for hvac replacement or installation in Unincorporated Union County?

Permit required

Yes. In Oregon, hvac replacement or installation generally requires a permit, and Unincorporated Union County is no exception.

ORSC R105.1 requires a permit to install, alter, repair, or replace any gas or mechanical system; the mechanical exemptions in R105.2 cover only portable appliances, minor parts, and small self-contained refrigeration units. BCD lists installing or changing any part of a heating or cooling system that must be vented, and installing or altering gas piping, as work that needs a mechanical permit. Minor labels are low-cost permits sold only to licensed contractors; an owner doing the work buys a regular permit from the local building department or BCD. BCD notes that State Fire Marshal licensing law requires anyone, including homeowners, who installs or alters an LP gas appliance, piping, or vent to be licensed.
