The Short Answer
A full bathroom remodel in Greer requires a permit if you're moving plumbing fixtures, adding electrical circuits, installing a new exhaust fan, converting a tub to a shower, or moving any walls. Surface-only work (new tile, vanity swap in place, faucet replacement) is exempt.
Greer's Building Department follows the South Carolina Building Code (currently aligned with 2015 IBC), which requires permits for any work that alters the plumbing, electrical, or structural system of a bathroom. Unlike some nearby municipalities that bundle cosmetic and structural permits into a single application, Greer Building Department treats fixture relocation and new electrical circuits as separate permit triggers — meaning a homeowner replacing a toilet in place pays nothing, but moving that toilet even 18 inches requires a full plumbing permit. The city's online permit portal (accessible through the City of Greer website) allows over-the-counter applications for straightforward projects, but plan review for bathroom remodels typically takes 2-5 weeks because the city requires detailed waterproofing specs (cement board brand, membrane type, drain pan detail), GFCI/AFCI circuit diagrams, and exhaust duct termination confirmation — details that often get missed on first submission. Greer's piedmont clay soil means drainage and trap-arm slopes are scrutinized during rough plumbing inspection. Owner-builders are permitted under SC Code § 40-11-360, but the city still enforces inspections at rough plumbing, rough electrical, and final stages.

What happens if you skip the permit (and you needed one)

Greer SC bathroom remodel permits — the key details

The primary code driver for bathroom remodels in Greer is the South Carolina Building Code, which adopts the 2015 International Building Code with state amendments. For plumbing, IRC P2706 (fixture trap requirements) and IRC P3005 (water heater connections) apply directly. The critical local wrinkle: Greer's Building Department requires a waterproofing detail sheet before rough plumbing inspection if you are converting a tub to a shower, installing a new shower, or moving a shower location. This detail must specify the membrane system (e.g., RedGard, Schluter, Wedi, or equivalent) and show that it extends 6 inches above the highest point of water spray (IRC R702.4.2 compliance). Cement board alone is not acceptable as a waterproofing assembly in Greer; you must show a secondary membrane. Many homeowners and small contractors submit plans showing only cement board and drywall, forcing a rejection and plan resubmission — adding 2-3 weeks to the timeline. The waterproofing schedule matters because Greer's piedmont clay soil can hold moisture, and improper shower pan construction has been a source of secondary damage claims in older homes.
