Somerville Land Use Committee Meeting - October 16, 2026

The Somerville Land Use Committee convened on October 16, 2026, to discuss and advance several zoning amendments. The meeting focused on routine approvals, a technical fix to parking maximums, and extensive deliberation on accessory dwelling units (ADUs), including a proposed amendment to comply with state regulations. The committee voted to recommend approval on several items and left the ADU discussion open for further refinement.

Discussion Items

• Removal of Ground Story Elevation Requirement (Items 26-1259 & 26-1373): The committee discussed an amendment to remove the mandatory two-foot ground story elevation requirement for residential buildings. Planning Director Bartman explained that the requirement, originally intended for stylistic consistency, has created accessibility issues, particularly with ramps, and that such decisions should be left to property owners. Councillor Klingon raised concerns about potential flooding and pipe freezing, but Director Bartman noted these are handled through other permitting processes. Councillor Sae inquired about flood-prone area considerations for large developments, and Director Bartman confirmed that the Engineering Division manages site-specific stormwater and flood concerns. Councillor Kampen proposed an amendment to the mayor's version to also strike related language in the non-binding architectural design guidelines, which was approved. The amended item was then recommended for approval.

• Clarification of Principal Entrance Requirements (Item 26-1373): This amendment allows principal entrances to be on the side of a building if a ground-story unit has a front door, and permits principal entrances on any side of an external accessory dwelling unit (ADU). Director Bartman explained that this is to accommodate modern triple-decker designs and ADU flexibility. Councillor Kampen questioned the logic of allowing a rear door on an ADU, but Director Bartman clarified that building codes regulate proximity to lot lines. Councillor Sae requested visuals for future discussion. The committee recommended approval.

• Fixing Parking Maximum Typos (Item 26-1258): The committee approved a technical correction to fix typos in the parking maximums in the zoning code. Director Bartman confirmed it reflects the original intent of a prior amendment.

• Updating Terminology for Affordable Dwelling Units (Item 26-1338): The committee approved a name change from "ADU" (affordable dwelling unit) to "Price-Restricted Dwelling Unit" (PRDU) and standardized related terminology to avoid confusion with the state's use of "ADU" for accessory dwelling units. This was a streamlining effort triggered by the state ADU law.

Accessory Dwelling Units (ADU) – Item 4

This was the main focus of the meeting. The committee discussed a proposed amendment (Item 4) to bring the city into compliance with state ADU regulations. The mayor's proposal allowed for a 1,728-square-foot maximum (three 576-square-foot floors), which led to significant debate.

• Director Bartman's Overview: He explained that the state regulations require municipalities to permit at least one ADU per lot, with dimensions that must match the principal structure's building type. The 1,728-square-foot figure was a starting point based on measuring existing backyard cottages.
• Councillor Davis: Expressed strong frustration, stating the current implementation is not what the council intended. He said the mayor confirmed that the 1,500+ square-foot figure was not a firm position, and that the mayor has no objection to reducing it. He advocated for significant reductions, including a 900-square-foot cap, a 1.5-story height limit, and other levers to ensure ADUs remain "backyard cottages," not full-sized houses.
• Councillor McLaughlin: Defended the overall policy, rejecting claims of widespread displacement. He requested data from the city solicitor on the legal interpretation of the state law, and data on demolitions and condo conversions since the new zoning code.
• Councillor Klingon: Questioned the complexity of the state law, noting that it appears to require matching the principal building's dimensions, which could allow three-story ADUs. He expressed a desire to limit size and height.
• Councillor Sae: Shared concerns that the state version could lead to "boxes" in backyards, supporting a 900-square-foot cap and a 1.5-story limit. She asked if the city had submitted comments to the state.
• Councillor Kampen: Proposed capping the total square footage at 1,152 square feet (two floors of 576 square feet each) to naturally limit the building to a 1.5-story cottage. He argued this would be a straightforward solution and more likely to produce the intended housing type.
• Councillor Davis: Raised concerns that developers will find ways to exclude basements from square footage calculations, and requested a review of green score requirements to address stormwater runoff.

Committee Decision: The item was left in committee for further refinement. Councillor Kampen will work with staff to prepare revised language with a 1,152-square-foot cap, a 1.5-story height limit, and provisions to ensure basements are counted toward the total.

Key Outcomes

• Items 26-1259 and 26-1373 (Ground elevation & Principal entrances): Recommended for approval with amendment to strike architectural guidelines.
• Item 26-1258 (Parking maximums): Recommended for approval.
• Item 26-1338 (Terminology update): Recommended for approval.
