Swapping a furnace or air handler feels like routine maintenance, but mechanical work is one of the trades that almost always needs a permit and an inspection. The "like-for-like" exemptions people cite usually cover electrical fixtures and water heaters, not HVAC equipment.

Fort Mill publishes no online exemption list and has no online permit portal, so anything beyond the plain South Carolina baseline should be confirmed by phone with the town's Building & Codes office before you start.

Permits, inspections, and the repairs that trigger them all add time and cost to a sale. If you would rather skip the whole process, RobinOffer buys homes across the Carolinas as-is — no permits to pull, no repairs to make.
