Full Breakdown
Section 7-4-2-030(C)(1)(f) applies the International Plumbing Code, as adopted and amended by the Georgia Department of Community Affairs, to every plumbing installation in Marietta, including alterations, repairs, replacements, equipment, appliances, fixtures, fittings, and appurtenances connected to a water or sewerage system. Anyone who wants to erect, install, enlarge, alter, repair, remove, convert, or replace a plumbing system regulated by the construction codes must apply to the building official and obtain a permit under Section 7-4-2-050(A)(1) before starting, with ordinary minor repairs allowed without a permit only if the building official approves.
Plumbing work goes through three inspections under Section 7-4-2-050(H)(6)(c): an underground inspection after trenches are excavated and piping installed but before backfill, a rough-in inspection after framing is in place and all soil, waste, and vent piping is complete but before walls or ceilings are closed, and a final inspection once all fixtures are connected and the structure is ready for occupancy, with required tests set by the International Plumbing Code itself. 0 gpm at 80 psi for shower heads. No work may proceed past a required inspection point without the building official's written release.
Violations & Fines
Plumbing work performed without a permit, or piping concealed before the required underground or rough-in inspection is released, violates Section 7-4-2-050 and adds a penalty equal to 100 percent of the normal permit fee under subsection (G)(2). The building official can order work stopped in writing, require concealed piping to be exposed for inspection, and refer construction-code violations for prosecution as a misdemeanor under Section 7-4-2-090.
