relative to uniform municipal standards for regulation of home-based businesses.

HB 1351 establishes statewide standards for home-based businesses in New Hampshire, directly affecting homeowners operating such businesses and local municipalities that regulate them. The bill defines "no-impact" businesses (e.g., invisible, no customer visits) as allowed without permits in all zoning districts, while "low-impact" businesses (with up to 4 non-resident employees and ≤20 daily customer visits) require only ministerial registration. It preempts local rules that conflict with these standards, such as banning outdoor storage compliant with the bill, imposing stricter employee limits, or requiring special permits. Municipalities can no longer enforce categorical bans on home businesses unrelated to health/safety, like 2-client caps or blanket signage prohibitions. The law aims to standardize regulations while preserving residential character and neutral nuisance standards.
