Representative Alexander advocates for HB 577 to streamline accessory dwelling unit regulations

A proposed bill aimed at addressing New Hampshire's housing crisis took center stage during the Senate Commerce meeting on March 25, 2025. House Bill 577 seeks to streamline the process for homeowners to build accessory dwelling units (ADUs), a critical solution to rising housing costs and displacement issues affecting families, young professionals, and seniors.

The bill aims to create a more uniform framework for ADUs across the state, allowing property owners to construct one unit up to 950 square feet by right, without facing overly restrictive municipal regulations. Proponents argue that this change will empower homeowners to utilize their properties more effectively, providing additional living space for aging relatives or young adults, and potentially generating rental income to offset rising costs.

Representative Alexander, a key supporter of the bill, emphasized the importance of balancing local control with property rights. He noted that many municipalities impose confusing and unnecessary barriers that hinder homeowners from taking advantage of ADUs. "For too long, municipalities have made it nearly impossible for people to exercise their private property rights," he stated.

During the meeting, concerns were raised about potential negative impacts, such as communities becoming overrun with duplexes and declining property values. In response, Alexander dismissed these fears as exaggerated, asserting that the bill would not infringe on local oversight regarding safety and zoning standards.

The bill is set to take effect in three months, prompting discussions about whether municipalities should be given more time to prepare for its implementation. While some argued for a delay to ensure successful rollout, Alexander maintained that immediate action is necessary to quickly increase housing availability.

Support for HB 577 also came from the Business Industry Association, which highlighted the financial challenges of building ADUs, noting that the costs can be significant. They pointed out that while the bill expands the ADU statute to allow detached units, the financial burden remains a critical factor for many homeowners.

As New Hampshire grapples with a housing crisis, the passage of HB 577 could provide much-needed relief by enabling homeowners to create additional living spaces, thereby addressing the pressing issues of affordability and displacement in communities across the state.
