Zoning Density and Multi-Family Variances
Repeated variance requests for ADUs, detached duplexes, and multi-family definitions on non-conforming lots are driving calls for clearer zoning definitions and potential ordinance amendments.
Repeated variance requests have tested agricultural zoning limits on density and multi-family definitions across three ZBA meetings. The board has approved multiple requests by treating lot nonconformity as hardship while acknowledging the need for ordinance clarification. Amendments are now slated for Planning Board review and a March warrant vote.
The issue of zoning density and multi-family variances in agricultural zones emerged from repeated applications seeking relief from lot-size, use, and density rules on non-conforming parcels. On 2026-04-07 the Zoning Board of Adjustment considered a multi-family request at 40 Henry Bridge Road that sought exceptions for use, dwelling units per acre, and septic systems; the board approved all three variances 3-2 after determining that wetlands and slopes created hardship.
That decision illustrated how unbuildable land could be treated as justification for higher density, prompting further applications that tested the definition of multi-family development itself. On 2026-05-05 the board heard the Jordan Dupree request for a variance from the multi-family definition to allow a detached duplex; despite neighbor objections over historic character and precedent, the board approved the variance and sent the matter to the Planning Board.
By 2026-06-02 the board explicitly recognized that ambiguous definitions were generating “glossary variances” and agreed that the Planning Board should draft clearer language on dwelling types and density. The same meeting approved an ADU variance at 521 Mountain Road on a sub-five-acre lot of record, reinforcing the pattern of granting relief based on pre-existing nonconformity.
These successive approvals have raised stakes for agricultural-zone preservation versus accommodation of accessory and multi-family housing on legacy lots. The board has signaled that ordinance amendments addressing definitions will be prepared by December for a March warrant vote, after joint discussion with the Planning Board.
On 2026-07-07 the Zoning Board of Adjustment continued its focus on ambiguous definitions by reviewing multi-family use, ADU requirements, and home occupations, noting that current rules may exceed state law under House Bill 544. The board agreed to compile a list of items, specifically citing Section 5.12, for a joint workshop with the Planning Board.
The board plans to prepare a list of items to discuss during a potential Planning Board workshop in October or November.
