Newburyport hearing on zoning overhaul spotlights clash over ‘mansionization’ fixes

Newburyport City officials and residents debated a wide-ranging proposal on April 15 to slow what sponsors called ‘‘mansionization’’—the redevelopment of modest homes into much larger single-family houses—by adding floor-area-ratio limits, lowering height limits and adjusting lot rules.

Sponsors of Ordinance 221 told a joint meeting of the Planning Board and the City Council’s Planning and Development Committee that the changes are intended to preserve smaller, naturally affordable homes and to offer incentives for two-family buildings. The presenters said the proposal would limit single-family houses in targeted R2 neighborhoods outside the city’s demolition-control overlay to a floor-area ratio (FAR) of 0.25 or 1,850 square feet (whichever is greater), lower single-family height to 25 feet (30 feet inside the DCOD), and permit two-family buildings at a 0.40 FAR with reduced lot-area and frontage requirements to encourage duplexes.

The sponsors said the plan would be targeted to zones mapped on a presentation and would grandfather applications already filed with the zoning administrator as of March 31, 2026. They cited local examples of houses that were replaced with much larger homes and said the package draws on goals in Newburyport’s 2017 master plan.

But the proposal drew a brisk and often critical set of public comments and technical questions from board members. Several planners, architects, builders and longtime residents said the measures as drafted were too broad, poorly notified to owners who might be affected, and likely to have unintended consequences for older homeowners who need modest additions or for owners looking to age in place.

"This 1,850 square foot maximum and 0.25 FAR is wrong," said real-estate professional Rick Zambrano, questioning whether the limits would prevent families from adding a small bedroom or a bathroom. "It tells people their homes are forever frozen." (Comment quoted during public comment; attribution per public-comment roll call.)

Other speakers, including architects and a former zoning board member, said the proposed height reduction to 25 feet could force awkward design compromises on sloped lots and might unduly narrow homeowners’ options. Several speakers asked for more analysis showing how many properties would be affected and urged a sampling approach before adopting citywide dimensional controls.

Planning board members and the city’s zoning administrator, Jennifer (first referenced as zoning administrator), answered detailed questions about what counts in gross floor area, how assessor records are used, and how exemptions would work. Staff explained proposed exclusions from gross floor area, including basements more than 50 percent below grade, attic space under 6 feet in height, detached accessory dwelling units (ADUs), up to 528 square feet of garage, and up to 200 square feet for small accessory structures. The sponsors said these exclusions were intended to focus limits on above-ground massing rather than storage or garages.

Several councilors and board members told sponsors they supported the goal of preserving neighborhood scale but wanted either more data or narrower, more targeted changes. Some suggested alternative or complementary strategies—such as allowing smaller conforming lot divisions, or creating explicit paths to build multiple small homes on a lot—rather than imposing a single numeric cap.

After hours of presentation, questions and public comment, the Planning Board and committee agreed to continue the public hearing on Ordinance 221 so staff and sponsors can post revisions and provide impact examples; the committee set a continuation for April 28. The hearing remains open and no final action was taken on Ordinance 221 at this meeting.

What happens next: Sponsors and staff said they will post revised language and sample parcel analyses in advance of the continuation. The Planning Board and Committee signaled they want at least one more meeting for public input and more time for staff to assemble a clearer, data-driven impact picture.
