JurisdictionCity limits or county decides your reviewer
Greenville has a city building and permitting department, and Greenville County has its own for unincorporated addresses. Greer, Simpsonville, Mauldin and Travelers Rest run their own as well. Two spaces four minutes apart can sit under different reviewers with different submission requirements and different queues. Confirming jurisdiction is the first item on the walkthrough, not a detail sorted out later.
ApprovalsSpecialty reviews run on separate tracks
The building permit is rarely the only approval. Food service brings a retail food establishment plan review through the South Carolina Department of Public Health. Hood suppression and egress go to the fire marshal. Medical and dental add their own layers. These run parallel to building plan review and they do not wait for each other, so a project that treats them as sequential loses weeks it never had to lose.
UtilitiesUtility capacity and fees are real line items
Renewable Water Resources handles regional sewer and Greenville Water handles the taps. Capacity and tap fees are owner costs that get discovered late on projects nobody checked early. On a change of use, whether the existing electrical service and sanitary connection carry the new load is the single most expensive assumption on the job, and it is verified on the first walkthrough here — before a number is written down.
Design reviewDowntown carries a design review layer
Work in the downtown design review districts can require review of exterior changes, signage and storefront alterations by the city’s design review board panels. That is a calendar item with its own meeting schedule. It rarely kills a project, and it regularly adds weeks to one that assumed a storefront change was a permit-and-go.
