Which NFPA 10 edition has your state adopted?
Updated August 2026Reviewed August 2026
Ask what an extinguisher cadence is and you will get a number. Ask which edition of the standard that number came from, and in this trade the question usually goes unanswered, including by the people selling you software to schedule it.
Why the edition is the real question
An NFPA standard is a private consensus document. It becomes enforceable in a place only when that place adopts it, by statute or by administrative rule, and adoption names an edition. A jurisdiction that adopted a 2010 edition is working to a 2010 edition until it adopts another one, whatever the current edition says.
So "per NFPA 10" is an incomplete sentence. The complete one names the edition in force where the building is, and adds that the local authority may have amended it.
The adoption records this research could read
Of the fifty-one jurisdictions in the state licensing layer, twenty-eight carry an adoption record that this research was able to fetch and quote. Some name an edition of NFPA 10 directly. Others adopt a fire code, most often an edition of the International Fire Code or of NFPA 1, which then carries the extinguisher requirements through by reference.
The full record for each jurisdiction, with the rule or statute that made the adoption and a link to it, is on that jurisdiction's own page in the state licensing layer, and the whole set is filterable in the state requirement lookup.
Twelve years separate the oldest from the newest
Among the jurisdictions whose record names an NFPA 10 edition outright, Indiana sits at the 2010 edition, South Dakota at 2013, Texas, Nevada and Maine at 2018, Alaska referencing 2021, and Georgia and Illinois at 2022. That is a twelve-year spread across states whose buildings look identical from the kerb.
Fire codes spread similarly. Adopted International Fire Code editions on record here run from 2012 to 2024, and several states adopt an edition of NFPA 1 or NFPA 101 instead. A schedule built on the assumption of a single national edition is built on something that has never been true.
Twenty-three jurisdictions with no record here
The remaining twenty-three carry no adoption record in this data, and that is a statement about what could be read rather than a finding about what exists. Agency sites that refuse automated requests, guidance published only as a scanned document, and rules served as a file to download rather than a page to read all produce the same result: an honest blank.
A blank is not permission. Where this data names no edition, ask the state fire marshal and the local authority which edition is in force before you rely on an interval.
How to confirm the edition in force
Ask two questions of two different bodies, because the answers can differ. Ask the state fire marshal or the licensing agency which edition of the fire code and which edition of NFPA 10 the state has adopted, and ask for the rule number. Then ask the fire marshal for the city or county where the work is whether they enforce that edition or a later one, and whether there are local amendments.
Get both in writing where you can. An adoption record can be superseded between one job and the next, and legislation moves faster than the pages that summarise it. Cadences vary by jurisdiction — verify with your AHJ.
Why nobody else's page names an edition
Because naming one costs work. It means finding the adoption rule for each jurisdiction, reading it, and recording what it says, and it means writing "we could not confirm this" on the ones that refuse to be read. It is easier to write one national number and move on, which is what most of this niche does.
The adoption record is also the part of this data most likely to move, so it lives in a data module rather than in the sentences of a page: one edit updates every surface that renders it.
Frequently Asked Questions
- Which edition of NFPA 10 applies to my building?
- The one your jurisdiction has adopted, which is not always the current edition. Records read for this data name editions from 2010 through 2022 across different states. Check your state page and confirm with the state fire marshal and your local authority.
- Does the current edition of a standard apply automatically?
- No. A standard has force only through adoption, and adoption names an edition. A jurisdiction stays on the edition it adopted until it adopts another one.
- What if my state has no adoption record on this site?
- It means this research could not read one, not that none exists. Ask the state fire marshal for the rule number and the edition, and ask your local fire marshal whether they enforce a later edition or local amendments.
