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.

Rock Hill runs its own permitting inside the city limits — not York County's rules — and historic-district properties may also need a Certificate of Appropriateness before any exterior change.

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.
