New Hampshire Bill Would Define and Regulate Tiny Houses and Yurts
New Hampshire's HB1681 would give tiny houses and yurts their first formal legal definition under state law, with six Republican sponsors pushing the bill through the House Housing Committee.
Six Republican members of the New Hampshire General Court have introduced legislation that would establish a formal statutory home for tiny houses and yurts, treating them as a recognized category of innovative housing under state law for the first time. House Bill 1681, amended and revised in mid-March 2026, would create a new framework within RSA 674, the chapter of state law governing land use and zoning. The bill is before the House Housing Committee.
The bill's official subject covers three distinct areas: the definition, inspection, and local approval of tiny houses and yurts as innovative housing structures. Rep. George Grant leads the sponsorship, joined by Reps. Brian Cole, Lisa Post, Michael Aron, Sherri Reinfurt, and Skip Rollins, all Republicans.
One of the bill's more consequential provisions, according to regulatory guidance published for New Hampshire builders, would allow third-party inspections for off-site builds, a change that could meaningfully speed up modular and prefab projects. Currently, tiny house permits in New Hampshire involve multi-stage approvals starting with zoning clearance, followed by inspections at foundation, framing, mechanical, and final stages. Permit fees range from $500 to $5,000 depending on the municipality, and rural projects can trigger additional environmental reviews for septic systems.
The regulatory baseline for permanent tiny dwellings in New Hampshire is the 2021 International Residential Code Appendix Q, which caps structures at 400 square feet, not counting loft space, and sets a minimum ceiling height of 6 feet 8 inches. THOWs, tiny houses on wheels, are classified separately as RVs and treated as temporary use rather than permanent dwellings.
HB1681 arrives in the wake of earlier state-level movement on the issue. House Bill 588, which took effect in 2024, explicitly defined tiny houses and required municipalities to permit them in single-family zones. HB 577 addressed ADU conversions. No statewide ban on tiny homes exists in New Hampshire; enforcement has operated through local zoning ordinances and building permits, a patchwork that HB1681 appears aimed at standardizing from the top down.
The bill had recorded three legislative actions as of this week, with the House Housing Committee serving as its primary venue for review.
