Zoning Reform Bill Splits Lawmakers Along Local-Control Lines

A bill that would limit how large a minimum residential lot size municipalities may require has emerged as the most closely watched housing measure of the current legislative session, drawing hours of testimony from both housing advocates and municipal officials defending local zoning authority.

Supporters argue that oversized minimum lot requirements in many New Hampshire towns function as an effective ban on the kind of moderate-density housing the state most needs, pricing out the starter homes and smaller lots that once characterized many of its town centers. Opponents, including several municipal associations, counter that the bill overrides local decision-making on an issue towns are better positioned to judge based on infrastructure capacity, such as septic systems and rural road networks.

Legislative leadership has not indicated when a floor vote might occur, and several amendments have already been proposed that would carve out exceptions for towns without municipal water or sewer systems. Housing advocates say even a narrowed version of the bill would represent meaningful progress after similar proposals stalled in prior sessions.
