Full Breakdown
Title 12, Chapter 5 of the Smyrna Municipal Code adopts the International Plumbing Code, 2024 edition, and modifications thereto, by reference as part of the municipal code, and calls it "the plumbing code" (§ 12-501). The Town Council enacted it with the rest of the new Title 12 in Ord. No. 26-13, adopted March 10, 2026, which repealed the former Title 12.
Section 12-502 lists the local modifications, each of which fills in a blank the model code leaves for the jurisdiction. Section 101.1 Title inserts "Town of Smyrna, TN" in place of the jurisdiction name. Section 106.6.3 Fee refunds inserts "100%" in lieu of the blank percentage in subsections 2 and 3. Section 305.4.1 Sewer depth inserts "12" in both locations. Section 603.1 Size of water service pipe inserts "1 inch in lieu of ¾." Section 903.1.1 Roof extension inserts "8 inches" in place of the blank number.
The residential code chapter carries matching entries for homes. Under § 12-602(20), Section P2603.5.1 Sewer depth replaces [NUMBER] with 12 in both places. Under § 12-602(21), Section P2902.5.3 Lawn irrigation systems deletes the words "an atmospheric-type vacuum breaker, a pressure type vacuum breaker or" from the first sentence.
Section 12-503 requires at least one copy of the plumbing code in the Town Clerk's office, kept there for the use and inspection of the public. Chapter 5 does not itself print permit fees or name the enforcing official. By contrast, the mechanical code chapter names the building official or designee for enforcement in § 12-402, so anyone pulling a plumbing permit should read the two chapters together with the fee schedule the Town Council adopts.
Violations & Fines
A violation of any provision of Chapter 5 subjects the offender to a penalty under the general penalty provision of the Smyrna Municipal Code, and each day an offense occurs constitutes a separate violation (§ 12-504). The chapter prints no dollar figure. For homes built under the residential code, § 12-604 separately makes it unlawful for any person to violate or fail to comply with any provision of the residential code as adopted and modified.
