In a move aimed at addressing the growing housing crisis in New Hampshire, the state legislature has introduced Senate Bill 84, which seeks to reform zoning procedures for residential housing. Introduced on January 22, 2025, the bill establishes maximum lot size requirements based on the availability of municipal or community sewer and water infrastructure, a response to increasing demands for housing amid concerns about environmental sustainability and infrastructure capacity.

The bill stipulates that for lots without municipal or community sewer, the maximum lot size is set at 66,000 square feet. For those with municipal water, the limit is reduced to 44,000 square feet, unless evidence shows inadequate water capacity. In areas with municipal sewer, the maximum lot size is further restricted to 22,000 square feet, contingent upon proof that the sewer system can support additional homes. This framework aims to streamline the development process while ensuring that local infrastructure can handle increased residential density.

However, the bill has sparked notable debates among stakeholders. Critics argue that the new regulations could impose significant costs on municipalities, which will need to amend local zoning ordinances and assess the adequacy of their water and sewer systems. The New Hampshire Municipal Association has indicated that these changes could lead to indeterminable increases in local expenditures as towns navigate the complexities of compliance and evidence gathering to challenge the new lot size requirements.

The implications of Senate Bill 84 extend beyond mere zoning adjustments. By potentially increasing the number of homes that can be built in areas with adequate infrastructure, the bill could alleviate some pressure on the housing market, which has seen prices soar in recent years. However, the bill's effectiveness will largely depend on how municipalities implement these changes and whether they can balance development with environmental concerns.

As the bill moves through the legislative process, its future remains uncertain. Supporters argue that it is a necessary step toward addressing housing shortages, while opponents caution against the potential strain on local resources and the environment. The bill is set to take effect on July 1, 2025, if passed, marking a significant shift in New Hampshire's approach to residential zoning and development.
