Summary
Longmont adopts the 2024 International Plumbing Code by reference under Longmont Municipal Code § 16.16.010, with the city's own amendments controlling wherever they conflict with the model text. Ordinance O-2026-27 rewrote the plumbing chapter on June 9, 2026, resetting permit fees, valuations, refunds, appeal routing and violation penalties alongside the newer code edition.
Pursuant to C.R.S. title 31, article 16, part 2, as amended, and article IV, part 4.9 of the Charter, there is adopted as the plumbing code of the city, by reference thereto, the International Plumbing Code, 2024 edition, including appendices B, C, D, E and F, published by the International Code Council, Inc., 4051 West Flossmoor Road, Country Club Hills, IL 60478, that code to have the same force and effect as if set forth in this chapter in every particular, save and except such portions as are added, amended, deleted, or replaced in this chapter. All references in this Code to the International Plumbing Code are to the edition referenced in this section.
Full Breakdown
16 adds, amends, deletes or replaces a section. m. Monday through Friday, and a working copy stays with the chief enforcement officer; the public can also buy a copy at cost. 1 is amended to insert "the City of Longmont" as the jurisdiction name. 2, are deleted outright, so Longmont does not offer an annual blanket plumbing permit. 2 is replaced: a permit application lapses 365 days after filing unless pursued in good faith or a permit is issued, though the code official may grant one or more written-request extensions of up to 180 days each on a showing of justifiable cause.
3 must be stamped "Reviewed for Code Compliance," printed in color, and kept on site for inspection. 3). 6 return 80 percent of the permit fee if no work was ever done, or 80 percent of the plan review fee if an application is withdrawn before review concludes, minus any outside consultant cost; refund requests must be filed in writing within 180 days of payment. 1). Section 202 adds a local definition: a grease trap is a passive interceptor rated at 50 gpm or less.
Violations & Fines
Sections 114.1 through 114.4 make it unlawful to erect, install, alter, repair, relocate, add to, replace, demolish, use, occupy or maintain plumbing work in violation of the code. Each day or part of a day a violation continues is a separate offense, punishable under chapter 1.12 of the Longmont Municipal Code. Paying one penalty does not excuse the violation or allow it to continue; the responsible party must still correct or remedy the defect within a reasonable time. Every violation is also declared a public nuisance that a court of competent jurisdiction can enjoin, and the city attorney may separately pursue legal or equitable relief.
