Only in some situations. As of October 1, 2025, Loudoun County requires plan submittal and review for certain residential fuel gas permits. Replacement permits that do not increase the appliance’s BTUs or change its physical location are not required to submit plans. If your new furnace is larger than the one it replaces or is moving to a different spot in the house, plan on that extra review step and a little more lead time.
Possibly, and that approval is separate from the county’s. Loudoun County states that applicants are responsible for contacting their homeowners association or property owners association for any additional requirements or approval. Plenty of Ashburn neighborhoods have architectural standards covering where outdoor equipment can sit and whether it needs screening. Tell us early if the outdoor unit is moving to a new location.
The county sets the bar. Loudoun requires that contractors hold a valid Virginia State Contractor’s License along with a Loudoun County business license, and you can ask any company for both before scheduling work.
