Marbletown adopts zoning change to permit ADUs, approves negative declaration

The Town of Marbletown board adopted a zoning amendment (Local Law 1 of 2025) to allow accessory dwelling units (ADUs) as part of an effort to increase housing options. The board also completed a full environmental review and voted to file a negative declaration, finding no significant adverse environmental impacts from the proposed code changes.

During a public reading of the environmental assessment form, board member Tracy summarized the purpose of the amendment: to implement the town's comprehensive plan policy and to provide housing opportunities compatible with the town's scale while paying special attention to seniors, low-income households and young families. The EAF stated the changes would permit one ADU on a lot and allow a second ADU under larger-acreage and affordability conditions.

Board members discussed specific program mechanics and grant opportunities. Staff and board members explained that a RUPCO-administered county grant program will provide up to $125,000 per ADU for qualifying homeowners, with affordability covenants attached. The board clarified that a first ADU may be permitted by right if setback and health-department/septic requirements are met; second ADUs are subject to acreage thresholds (property size must be 125% of district minimum acreage) and affordability conditions (the second unit must be rented at 80% or less of area median income for 10 years when funded through RUPCO).

One board member described the change as a tool to create affordable, long-term housing while also limiting short-term rentals: ADUs will not be permitted for short-term rental under the new law. The board voted to adopt the negative declaration and then the local law; both motions passed.
