Land Use Committee Summary – May 7, 2026

Items Recommended for Full Council

Affordable Housing Overlay Amendment (Section 8.1) – Recommended 3-0 as amended

The committee recommended approval of changes to the city's Affordable Housing Overlay that would allow larger affordable housing buildings—up to eight stories—with additional dimensional flexibility and fewer use restrictions. The eight-story limit was specifically calibrated to enable mass timber construction, a newer building type that can be financially efficient at that height under the state building code.

Key points:

• Chair Ewen-Campen had previously considered raising the limit to nine stories but dropped that idea after Director Bartman explained that nine stories triggers a more expensive building code construction category (limiting exposed wood, requiring additional fireproofing).

• A previously discussed extra parking setback for affordable buildings was not included in the final language—the committee agreed it would be counterproductive to apply stricter standards to affordable housing than to market-rate buildings.

• Upper-story step-backs on the front are removed (they reduce unit count for little benefit), but side setbacks abutting NR/MR-3 districts are retained.

• The green score remains at status quo (Director Bartman noted higher numbers were possible but the committee chose not to increase them).

• Three technical amendments fixed typos and ambiguities in Table 8.1.6: changing "lot depth" to "lot width" in two places under side setback, and changing "greater than 100 feet" to "greater than or equal to 100 feet" to close a gap for lots exactly 100 feet wide.

Dormer / Upper-Story Zoning Amendment (Citizen Petition) – Recommended 3-0 as amended

The committee recommended approval of a citizen-initiated amendment (from 26 registered voters) that significantly relaxes restrictions on dormers in the Neighborhood Residence (NR) district, with two notable modifications from the original proposal:

Two-foot front setback retained. Despite the petitioners' request to remove the front setback entirely, the committee voted to direct staff to draft language keeping a 2-foot front setback for dormers. Director Bartman argued the setback preserves the visual character of pitched-roof homes (creating an "optical illusion" that the third story isn't a full floor) without meaningfully reducing usable space. Chair Ewen-Campen noted that all the example dormers shown in the petitioners' own presentation had this setback.

Three-story-by-right provision removed. The original petition would have allowed detached houses, semi-detached houses, and duplexes in NR to be built as three full stories by right (alongside the existing dormer rules). The committee voted to strip this from the amendment, with members arguing:

• Three-story-by-right would effectively moot the dormer standards (anyone could build a flat-roofed cube instead).

• Triple-deckers (already allowed by right) provide a path for three-story buildings.

• A change of this magnitude warrants its own broader public conversation.

• Councilor McLaughlin: "Allowing the dormer is what makes sense."

Backyard cottages excluded. The committee also voted to amend Table 3.1.13 to set gable and shed dormers to "N" (not allowed) for backyard cottages, deferring that question to the broader backyard cottage amendments expected in May/June. Members agreed adding full-width dormers to backyard cottages right now would exacerbate concerns already raised about cottage size.

Final language will be drafted by planning staff and presented as a floor amendment at the next full council meeting (May 14).

Items Kept in Committee

Transit-Oriented Height/Density Bonus Amendment – Kept in Committee

Director Bartman provided an update on the related Gilman Square / broader upzoning project. Planning staff are continuing the work behind the scenes and will:

• Meet with the Gilman Square Neighborhood Council to introduce newly hired planning staff.

• Present the four zoning map options at a Ward 4 "Slice of the City" pop-up open house.

• Hold a follow-up open house collaboratively with the neighborhood council.

Bartman noted his department is now fully staffed for the first time in a long time, including all senior planners and the recently hired deputy director.

Committee Discussion

Building Code and Mass Timber

Councilor McLaughlin asked detailed questions about why the building code limits mass timber to eight stories. Director Bartman explained the International Building Code's tiered construction types, the 70-foot high-rise threshold (triggering firefighter command centers, hose connections, etc.), and the trade-offs between fire-resistance categories. The eight-story / 85-foot limit represents the most cost-effective mass timber configuration.

Dormer Survey Results

Director Bartman shared results from a Planning Department survey conducted via SomerVoice and the department newsletter. About 90% of respondents supported relaxing dormer regulations, and one-third wanted to go even further than what staff proposed. A smaller group strongly opposed larger dormers, calling the 2-foot setback a "token ghost roofline reference." Bartman cautioned that response volume was not statistically representative of the city. Councilor Sait asked clarifying questions about how the survey was conducted and how residents could engage with future zoning changes.

Architectural Character

Significant discussion focused on whether to preserve Somerville's pitched-roof building stock. Bartman noted the city has thousands of gable-front homes from 1880-1920, gambrel-roof houses near Powderhouse, and flat-roof homes farther west—each reflecting eras of construction. The chair and several members expressed reluctance to make changes that would financially incentivize converting these into "cubes."

What's Next

• Full Council, May 14: Both items (affordable housing overlay and dormer amendment) head to full council. Chair Ewen-Campen will present the dormer amendment as a floor substitution using language drafted by planning staff (to avoid triggering a new public hearing).

• May/June: Backyard cottage amendments expected to come forward, including those filed by former Councilor Bill White and additional administration drafts.

• Near future: Gilman Square / upzoning open houses with Ward 4 residents and the Gilman Square Neighborhood Council.
