QUICK ANSWER
State Code-Edition Lookup
Code answers depend on which edition your jurisdiction enforces. New York might still be on 2018 IFC while California is on 2022 — citing the wrong edition gets your inspection failed. Pick a state to see every adopted code, the rule reference, the verified date, and the gotchas (CMS healthcare carve-outs, home-rule states, NYC + Chicago + Phoenix amendments, etc.).

HOW WE SOURCE THIS DATA
- Editions are pulled from the state authority (OCI / DCA / SBCCI equivalents) and cross-referenced against ICC Code Adoption Map + NFPA Compliance Tracker. Each row carries a last-verified stamp.
- Local amendments override the state-adopted edition in many jurisdictions. NYC, Chicago, Phoenix, Atlanta, and Boston all layer city-level amendments on top of the state code. Always confirm with the local fire marshal for city/county-specific requirements.
- CMS healthcare carve-out: Hospitals and Medicare-participating facilities enforce federal CMS-adopted editions of NFPA 101 (2012), NFPA 99 (2012), and NFPA 110 (2010) regardless of state adoption. State editions still apply to non-CMS occupancies.
- Home-rule states (TX, MO, IL, AZ, CO) have no statewide commercial code; each city or county adopts independently. We flag this in the keyNotes.
- If a code isn’t shown for a populated state, it’s either not adopted by that state or we haven’t verified it yet.
