Santa Rosa Planning Board discusses Missing Middle Housing initiative and zoning regulations

A pivotal discussion on "missing middle housing" took center stage at the Santa Rosa Design Review and Preservation Board meeting on August 21, 2025. City planners presented an initiative aimed at addressing housing shortages by introducing a new zoning district that encourages the development of smaller, multi-unit buildings in walkable neighborhoods.

Supervising Planner Amy Nicholson outlined the concept, which integrates into the recently adopted general plan. The initiative seeks to provide housing options that are more affordable and accessible, particularly for smaller households. While these units are not mandated to be affordable, their smaller size—typically around 1,000 square feet—could naturally lower costs for potential buyers or renters.

Nicholson emphasized that missing middle housing is characterized by its compatibility with existing neighborhoods, often resembling single-family homes, which helps to mitigate concerns about increased density. The proposed regulations would allow for developments that include duplexes, courtyard buildings, and other multi-unit structures, all designed to enhance community livability by reducing reliance on vehicles and promoting shared public spaces.

The board discussed the implications of this initiative, particularly in relation to the city’s eight historic preservation districts. Any new projects in these areas would still need to comply with existing landmark alteration permit requirements, ensuring that the character of historic neighborhoods is preserved.

The meeting concluded with a call for feedback from board members before the proposal moves to the planning commission and city council for further consideration. This initiative represents a significant step towards diversifying housing options in Santa Rosa, responding to evolving community needs and preferences.
