The Harwich Zoning Board of Appeals (ZBA) signaled a significant shift in town housing policy as members received updates on a proposed bylaw overhaul that would permit Accessory Dwelling Units (ADUs) up to 1,000 square feet by right. Member Chris Murphy, reporting from the Zoning Bylaw Committee, noted that the group has reached a consensus on the size increase and a mandate to prohibit short-term rentals of these units for periods of less than 31 days. The committee is meeting every Wednesday. We've agreed to a revised Accessory Dwelling Unit statute,
Murphy said, adding that the committee is also evaluating shape factors and the town’s 25% improvement rule.
The update comes amid internal efforts to clarify the ZBA’s authority within the town’s shifting administrative landscape. Chair Brian Sullivan informed the board that he drafted a formal memo to the Select Board to address perceived misunderstandings of the ZBA's quasi-judicial role. Based on correspondence and discussions, I'm not totally confident that the Select Board shares a common understanding of our statutory role and responsibility,
Sullivan stated. Member John August supported the outreach, remarking that this can't hurt. It's well written,
while Kenneth Dixon added, It's important that we are all on the same page.
Infrastructure and neighborhood character concerns emerged during the review of Case 2026-02 for 62 Sugar Hill Drive. Applicant Jeffrey Sulcen of Forest Hill Builders sought a special permit to increase site coverage from 25.8% to 27.4% for a 241-square-foot addition. The only increase in non-conformity is site coverage,
Sulcen explained, noting the project would not add a bedroom but would convert existing space for a new bathroom. To mitigate neighborhood impact, the board imposed a condition that all construction vehicles remain on-site. Motion Made by B. Sullivan to accept the documents, findings of fact, and conditions. Motion Passed (5-0-0). Following the closing of the public hearing, the board moved to the final vote. Motion Made by A. Donoghue to grant the special permit for 62 Sugar Hill Drive. Motion Passed (5-0-0). Clerk Alexander Donoghue noted that granting is consistent with the Gail and related cases as there will be no intensification of existing non-conformities.
The board also addressed environmental constraints at 32 Bellbrook Lane, where builder Benjamin Dill of Outermost Building and Renovation presented a request to downsize a previously approved project. We removed a mudroom and laundry area from the original plan because it put us in the flood zone,
Dill told the board, explaining the modification was necessary to avoid substantial changes to the existing structure. Motion Made by B. Sullivan to accept the documents and findings of fact. Motion Passed (5-0-0). The board subsequently finalized the request. Motion Made by A. Donoghue to grant an administrative modification for Case 2025-43. Motion Passed (5-0-0).
Longer-term policy discussions touched on the town’s traditional summer construction ban between Memorial Day and Labor Day. Dixon questioned the consistency of the restriction, noting, If a project is 'by right,' they can build in July, but if they need a special permit, we stop them. It should be the exception, not the rule.
While Sullivan agreed the board needs more flexibility, Donoghue cautioned that on small streets, construction vehicles and lawn services really inhibit traffic and pedestrians in the summer.
The board also reviewed a draft advertisement for the Cape Cod Chronicle to recruit alternate members, with Sullivan agreeing to revise the text to clarify that while prior zoning experience is helpful,
it is not strictly required for the volunteer positions.
