What the Pine Plains code says

An accessory dwelling needs a special use permit from the Planning Board in all eight base districts. The unit may be rented, but the principal dwelling must be owner-occupied for the duration of the permit.

Conditions the code attaches:

It must be accessory to an existing single-family detached dwelling, one per lot, attached or detached, and not in a front yard or a required side or rear yard (§ 100-56D).
Floor area is capped at 75% of the principal dwelling's gross floor area or 1,250 sq ft, whichever is less, with a 250 sq ft minimum.
The Planning Board may waive up to the 75% figure if the waiver is requested before the public hearing opens.
The applicant must show adequate sewer and water to Dutchess County Health Department standards.
In the Hamlet - Business district a single-family detached dwelling is prohibited, so the unit is possible only on a lot that already has one.
Accessory dwellings are not permitted in a New Neighborhood Development district, a floating district created by § 100-28.

ADUs vs. short-term rentals in Pine Plains

No local short-term-rental law on record - which is not the same as permission for Town of Pine Plains. As of June 2026 the Town of Pine Plains has no local short-term rental law, and that is not the same as permission. Confirm with the Town of Pine Plains Building Department before counting on short-term rental income. These are separate questions from whether you can build an ADU — a unit you're allowed to add isn't automatically one you're allowed to rent nightly, so check both.
