Primary-source summary
**Last reviewed**: April 2026
**Activity level**: Medium-to-High — long-standing statutory mandates on ADUs (RSA 674:72) and workforce housing (RSA 674:71) constrain every municipality; legislature has seen repeated 2023-2025 density-preemption attempts (HB 399 / HB 577 / HB 1661) and STR preemption bills (HB 1128). New Hampshire's zoning regime is grounded in the Town Meeting / Select Board governance model, so state mandates interact with a highly decentralized local process.Trigger predicate

Research notes
Enforcement: private right of action — appeal to ZBA, then Superior Court. Manufactured housing is presumptively allowed wherever conventional single-family is allowed, even if the local ordinance is silent on the topic. Cross-references HUD §5401 manufactured-home construction and safety standards.
