Yes. The Virginia Residential Code exempts replacement of mechanical appliances only when they are not fueled by gas or oil, so a gas furnace or boiler needs a permit even as a straight like-for-like swap. Fairfax County handles this through a Household Appliance permit, which is issued automatically once the application and fee are submitted and requires a single inspection.
More than a simple appliance swap. A new HVAC system in Fairfax County requires a Residential HVAC Certification uploaded before the mechanical permit is issued, plus an Air Leakage and Duct Leakage Test form submitted online and approved before the final inspection can be scheduled. Replacing any fuel-burning appliance also requires a Chimney Vent Certification.
It is a Fairfax County filing tied to newer equipment. Heating and cooling appliances installed for human comfort in one- and two-family dwellings that use A2L refrigerants require an A2L Refrigeration System Certification submitted to the county.
Not always. The City of Fairfax is an independent city with its own permitting through its Office of Code Administration, and homes in the towns of Vienna and Clifton require separate town approval uploaded to the county’s PLUS record in addition to the county permit.
