relative to the administration and enforcement of the state fire code.
HB 1555 modifies New Hampshire’s fire code administration to provide relief for existing buildings and streamline variance processes. It grants property owners a 20-year exemption from retroactively updating construction to meet new fire codes after receiving a certificate of occupancy (for permits issued July 1, 2026, or later). Local fire chiefs can approve variances from fire code requirements if safety is maintained, requiring property owners to provide fire safety engineer certification and sign an indemnification waiver assuming full liability for deviations. The bill also creates a new appeal path: decisions on variances can be reviewed de novo by the state fire marshal, with further appeals to the building code review board.

MODERATE
This diff reflects the standard transition from a bill adopted by both legislative bodies to its final enacted chapter form (Chapter 231). No substantive policy changes were made; all modifications are formatting, renumbering, and structural. The fiscal note was removed as it is not part of the enacted law, and approval/effective dates were added.
TECHNICAL
Section numbers changed from sequential (1, 2, 3) to chapter-prefixed format (231:1, 231:2, 231:3), which is standard when a bill becomes an enacted chapter.
The entire fiscal note section was removed, as it is not included in the final enacted version of a law.
Approval date (July 02, 2026) and effective date (July 01, 2027) were added at the end, which is standard for chaptered laws.
Header changed from 'VERSION ADOPTED BY BOTH BODIES' to 'CHAPTER 231 - FINAL VERSION,' and various whitespace/line-wrapping adjustments were made throughout.
