Under South Carolina law (S.C. Code Ann. 40-59-260(A), (B), (C), (E), (F); 40-59-265; 40-59-280; 40-59-20(6), (7); 40-59-30(A)): South Carolina licenses residential builders and residential specialty contractors under S.C. Code Title 40 Chapter 59, and 40-59-260 exempts the owner of record who builds for himself. The exemption applies only if the owner does the work himself, with his own employees, or with licensed contractors or registered entities, if the structure is intended for the owner's sole occupancy or occupancy by the owner's family and is not intended for sale or rent, and if the general public does not have access to it. The owner must personally appear and sign the building permit application, and the local permitting agency must hand over a disclosure statement whose statutory text reads in part: You must supervise the construction yourself. You may build or improve a one-family or two-family residence. The building must be for your own use and occupancy. It may not be built for sale or rent. The sale restriction is two years and is a presumption rather than a flat bar: 40-59-260(B) makes proof of sale or rent, or of offering for sale or rent, within two years after completion or issuance of a certificate of occupancy prima facie evidence that the project was undertaken for sale or rent, which forfeits the exemption and exposes the owner to the chapter's penalties. South Carolina then adds a step no other state in this wave has: 40-59-260(E) requires the owner to promptly record a notice with the register of deeds, indexed under the owner's name in the grantor index, stating that the building was constructed by the owner as an unlicensed builder, and failure to record revokes the statutory exemption. The exemption is from the licensing chapter, not from the permit, and 40-59-280 requires the building official to refuse a permit unless the applicant furnishes evidence of licensure, registration, or exemption.

How to apply in Greenville County

In Greenville County, replacing a residential water heater needs a permit before work starts, because swapping the appliance counts as installing regulated plumbing and fuel gas work, not an exempt repair. The application itself stays light: it identifies the work and its location, and most offices only ask for extra fuel or capacity details when the replacement changes fuel type or input size.

What most water heater permit applications include:

For Greenville County, a permit must be obtained before an owner or contractor installs, alters, or replaces any plumbing, fuel gas, or electrical system regulated by the code, which covers putting in a new water heater (IRC R105.1).
Water heater replacement is not on the code's short list of exempt plumbing work, and replacing defective piping with new material is expressly defined as new work that needs a permit and inspection (IRC R105.2).
For Greenville County, the application itself only has to identify and describe the work and describe the location of the building or work, which is why most offices can process a water heater permit as a short form rather than a full plan set (IRC R105.3).
Once a complete application is on file, the building official must act on it and issue the permit as soon as practicable if the proposed work conforms to code, which is the basis for the same-day or next-business-day turnaround many permit offices offer for a straight swap (IRC R105.3.1).
For Greenville County, the permit only stays valid if the work starts within the code's default window before it lapses, so scheduling the replacement and its inspection soon after the permit issues matters (IRC R105.5).

Inspections and closing out your permit

In Greenville County, a water heater swap normally draws one inspection, a final, since the work is exposed rather than buried behind new framing. That single visit confirms the relief valve and its discharge pipe, thermal expansion control and seismic strapping where the installation requires them, and, on gas units, adequate combustion air and an approved vent connection.

In Greenville County: the lifecycle has one required visit, the final inspection, made after the permitted work is complete and before the water heater goes into service; because a straight swap conceals nothing behind framing, offices typically do not schedule a separate rough-in visit for it (IRC R109.1.6).
In Greenville County: the inspector confirms the water heater is protected by either a separate pressure relief valve and temperature relief valve, or one combination valve rated for the appliance (IRC P2804.1).
In Greenville County: the relief valve's discharge pipe is checked for an unobstructed, un-trapped gravity path that ends through an air gap no more than 6 inches above the floor or pan, since a wrong discharge pipe is one of the most common reasons a water heater fails inspection (IRC P2804.6.1).
In Greenville County: where the water heater feeds a closed system, for instance behind a backflow preventer or check valve, the inspector looks for a thermal expansion control device sized to absorb the resulting pressure increase (IRC P2903.4.2).
In Greenville County: on a gas-fired unit, the inspector verifies the space provides enough combustion air, sized at 50 cubic feet per 1,000 Btu per hour of the appliance's input rating unless an engineered alternative method is used (IRC G2407.5.1).
In Greenville County: the gas unit's vent must tie into an approved venting system, which the inspector checks along with the vent's physical connections and support (IRC G2427.1, G2427.2).
In Greenville County: where site conditions call for them, the inspector also checks for a drain pan under a tank whose leakage would cause damage, and for seismic strapping in the upper and lower thirds of the tank in the seismic design categories and townhouse conditions where the code requires it (IRC P2801.6; P2801.8).

Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Greenville County permit portal or by phone at 864-467-7060.
