Kansas — Code Adoption Summary
Adoption model: Home-rule — no statewide building/electrical code for private construction; state adopted 2008 NEC only for state-owned buildings. County/city is the AHJ for everything else.

Statewide floor (narrow — state-owned only)
| Code family | Status | Notes | Source |
|---|
| Electrical (NEC) | 2008 NEC adopted for state-owned buildings only (2011-02-04) | NOT a general statewide mandate | bhs1.com |
| Building / Residential / Mechanical / Plumbing / Energy | No statewide code — 100% local adoption | | meltplan.com |
Adoption model & precedence
- Kansas is a true home-rule state (grouped with AZ, IL, NV, NY-outside-NYC as leave-it-to-locals per NFPA's own characterization) — the county or city decides, not the state.
- No safe statewide fallback exists for building/mechanical/plumbing/energy, and the state electrical floor applies only to state-owned buildings.
- Real-world variance is significant: a design compliant in Wichita may need real changes to permit in Overland Park.
Major cities / counties
| Jurisdiction | Notes | Building dept. |

| Wichita | 2018 IBC | wichita.gov |
| Overland Park | 2018 IBC (may differ in amendments from Wichita) | opkansas.org |

AHJ fallback (when local adoption is unverified)
- No safe statewide default exists for private construction.
- Action: identify the specific city/county AHJ and confirm its currently adopted IBC/IRC/IMC/IPC/IECC/NEC editions directly — never assume one KS jurisdiction's code applies in another.
