New Hampshire's updated state building code, which adopts the 2024 editions of the International Residential Code, International Plumbing Code and related codes with New Hampshire amendments, took effect on July 1, 2026. Through December 31, 2026, permit applicants may choose between the 2021 and 2024 editions. Beginning January 1, 2027, new permit applications must follow the 2024 codes. Next Step Property Services, a locally owned remodeling and handyman business based in Derry, is advising homeowners planning bathroom remodeling in Londonderry this winter or spring to account for the change in their planning.

A Transition Window That Closes December 31

The six-month concurrency period ends with the calendar year. A bathroom project that is still in planning in December and reaches permit application in January will be reviewed under the 2024 codes. For a homeowner scheduling a bathroom remodel in Londonderry for early 2027, the application date, not the date planning started, decides which edition applies.

The specific differences between the 2021 and 2024 editions, and whether a given scope of bathroom work needs a permit at all, are questions for the Londonderry building department. Next Step Property Services recommends a simple first step: before design decisions are final or materials are ordered, ask the building department which code edition will apply based on the expected application date.

Why Timing Matters for Winter and Spring Projects

Moving from an initial walkthrough to a defined scope, selections and a permit application takes time. A plan built around one assumption about the governing code can need adjustment if the application lands after January 1. Homeowners who plan early, ask about permit timing up front, and confirm requirements with the town are less likely to face scope changes late in the process.
