IFC —	NOT ADOPTED — NO INTERNATIONAL FIRE CODE, OF ANY EDITION, IS IN FORCE IN NEW HAMPSHIRE. NEW HAMPSHIRE IS AN NFPA FIRE STATE AND THE STATUTE SAYS SO IN ITS OWN DEFINITION. RSA 153:1, VI-a, QUOTED VERBATIM: "'New Hampshire fire code' or 'state fire code' means the adoption by reference of the Life Safety Code, NFPA 101, 2024 edition, and the Uniform Fire Code NFPA 1, 2024 edition, as published by the National Fire Protection Association and as amended by the state board of fire control and ratified by the general court pursuant to RSA 153:5." "INTERNATIONAL FIRE CODE" AND "IFC" APPEAR NOWHERE IN RSA 153:1 — CHECKED AGAINST THE STATUTE TEXT ITSELF THIS RUN, NOT ASSUMED. * THE NEGATIVE IS DOUBLY SEALED, AND THAT IS WHAT MAKES IT STRONG. (1) THE FIRE STATUTE AFFIRMATIVELY NAMES A DIFFERENT PUBLISHER'S BOOKS, SO THERE IS NO VACANCY FOR AN IFC TO FILL. (2) THE BUILDING STATUTE INDEPENDENTLY OMITS IT: RSA 155-A:1, IV ENUMERATES THE ADOPTED I-CODES ONE BY ONE — IBC 2021, IEBC 2021, IPC 2021, IMC 2021, IECC 2018, ISPSC 2021, IRC 2021, PLUS NEC 2023 — AND THE IFC IS NOT AMONG THEM (enumeration already transcribed verbatim on the NH IMC row c5b17531 and NOT re-fetched this run). NEW HAMPSHIRE RUNS ICC FOR BUILDING AND NFPA FOR FIRE, AS TWO SEPARATE STATUTORY PROGRAMS UNDER TWO SEPARATE BOARDS, AND RSA 155-A:2 BINDS BOTH AT ONCE: "All buildings, building components, and structures constructed in New Hampshire shall comply with the state building code AND state fire code." * CONSEQUENCE FOR THE READER: EVERY NEW HAMPSHIRE FIRE QUESTION IS AN NFPA 1 (2024) OR NFPA 101 (2024) QUESTION AS AMENDED BY SAF-FMO 300, AND SERVING IFC TEXT TO A NEW HAMPSHIRE READER IS WRONG ON THE PUBLISHER, NOT MERELY ON THE EDITION. A CROSS-REFERENCE FROM THE ADOPTED 2021 IBC TO "THE INTERNATIONAL FIRE CODE" POINTS A NEW HAMPSHIRE READER AT A BOOK THAT IS NOT LAW HERE — SAME TRAP AS MAINE (NFPA 1/101 2018, row 2f17df48) AND NEBRASKA (NFPA 1/101 2012, row c3b5559b). THREE NFPA FIRE STATES NOW EVIDENCED IN THIS TABLE, ON THREE DIFFERENT NFPA EDITIONS — 2012, 2018 AND 2024. NEVER INFER ONE FROM ANOTHER. *** EDITION DISCIPLINE: THE CURRENT NEW HAMPSHIRE FIRE EDITIONS ARE NFPA 1 2024 AND NFPA 101 2024 — READ FROM THE CURRENT STATUTORY TEXT THIS RUN.

Dual-compliance mandate: RSA 155-A:2 ("All buildings, building components, and structures constructed in New Hampshire shall comply with the state building code and state fire code."). The separate building-code track, which independently omits the IFC, is RSA 155-A:1, IV with the state building code review board at RSA 155-A:10 and local amendment power at RSA 674:51. *** NEW HAMPSHIRE IS A LEGISLATURE-NAMES-THE-EDITION STATE FOR BOTH PROGRAMS: the fire editions sit in RSA 153:1 and the building editions in RSA 155-A:1, so NEITHER CAN MOVE WITHOUT A BILL and the session laws are the only first signal — an agency page will never be one.
