Summary
Lee's Summit enforces smoke alarm requirements by adopting the 2018 International Residential Code in full under City Code § 7-900, and the city's own list of local amendments confirms it left the IRC's smoke-alarm section untouched even while it rewrote neighboring fire-safety rules on sprinklers and egress. The Building Official enforces compliance through the standard permit and inspection process.
The 2018 edition of the International Residential Code, including appendices E, H, and J, and its most current errata as published by the International Code Council is hereby adopted and incorporated in this chapter as fully as if set forth herein, excepting only such parts or portions thereof as are specifically added or amended.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 55 | Unified Development Ordinance: Supplement 15).
Full Breakdown
City Code § 7-900 adopts "the 2018 edition of the International Residential Code, including appendices E, H, and J," incorporating it "as fully as if set forth herein, excepting only such parts or portions thereof as are specifically added or amended" (Ord. No. 8584, § 1, 3-19-2019). The IRC's Section R314, Smoke Alarms, is one of the code's unmodified chapters: the city's own sequence of amendment sections running from § 7-901 through § 7-945 rewrites dozens of other IRC provisions, from garage-door fire ratings (§ 7-903) to receptacle spacing (§ 7-945), but none of them touches R314, so the ICC's national smoke-alarm placement, interconnection and power-source rules apply in Lee's Summit exactly as the Council wrote them.
" Builders and remodelers folding smoke alarms into a permitted job therefore answer to the Building Official as part of the same inspection that checks wiring and framing on any permitted addition or renovation, rather than to a separate fire-alarm office.
Violations & Fines
Failing to comply with any adopted provision of Chapter 7, including the IRC smoke-alarm chapter incorporated by § 7-900, is punishable under § 7-177: a fine of up to $500, up to 90 days in jail, or both, with each day a violation continues after notice counted as a separate offense. The Building Official may also issue a stop-work order under § 7-178 on a project found out of compliance.
