City Council approves new residential housing regulations for townhouses and duplexes

Maine's House Bill 1987 is making waves as it seeks to reshape the state's residential housing landscape. Introduced on March 6, 2025, the bill aims to expand the types of residential units permitted across various zoning districts, specifically allowing for the construction of townhouses on newly platted and vacant lots.

At the heart of the bill is a clear push to address Maine's housing shortage by permitting townhouses—defined as single-family units in attached groups—alongside traditional single-family homes, duplexes, and accessory dwelling units. This legislative move is designed to enhance housing availability while ensuring that municipalities maintain control over local zoning regulations to protect public health and safety.

Notably, the bill stipulates that townhouses can only be built on lots platted after June 1, 2025, or on vacant lots, which has sparked discussions among local officials and developers about the implications for urban planning and community development. Critics argue that the restrictions on accessory dwelling units on duplex lots could limit housing flexibility, while supporters emphasize the need for more diverse housing options to accommodate growing populations.

The economic implications of House Bill 1987 are significant, as it could stimulate construction jobs and increase property tax revenues for municipalities. However, the bill's success hinges on balancing development with environmental protections, as it explicitly prohibits residential projects in sensitive areas, including floodplains and historic sites.

As the bill moves through the legislative process, experts predict it could lead to a transformative shift in Maine's housing market, potentially easing the pressure on affordability and availability. With ongoing debates about the best path forward for housing in the state, House Bill 1987 stands as a pivotal piece of legislation that could redefine residential living in Maine for years to come.
