Full Breakdown
Village Code Chapter 7, Article 12, Plumbing Code, Section 7-12-1, Adoption, is the Village's own adopting and amending provision, enacted by Ordinance 15-179 on November 16, 2015. Subsection A adopts the current edition of the State of Illinois Plumbing Code, issued under 77 Illinois Administrative Code 890, by reference and makes it part of the Village Code as if fully set forth. Illinois has no separate statewide residential building code of its own outside this plumbing code, so plumbing work in the Village is governed by the state code as locally adopted, not an independent Oak Park plumbing chapter.
Subsection B requires the Village Clerk's office to keep three copies of the current State of Illinois Plumbing Code on file for public inspection, so a contractor or resident can review the exact standard being enforced. 5(g). A 2025 ordinance amending this article (Ordinance 25-120/25-154) further revised minimum-fixture-count and restroom-access rules tied to this adoption, showing the Village actively updates its local plumbing amendments rather than simply deferring to the state text. Any plumbing installation done without a permit or in violation of the adopted code is enforced through the Village's building permit and inspection process administered by the Development Customer Services Department.
Violations & Fines
Plumbing work performed in violation of the adopted State of Illinois Plumbing Code, including installing non-WaterSense fixtures, exposes the installer or property owner to the Village's general code penalty under Section 1-1-5: a fine of not less than $20.00 nor more than $750.00, with each day of a continuing violation a separate offense.
