What the Stony Point code says

In SR-R, RR and R-1, a separate dwelling for a caretaker or servant may be permitted as an accessory use to an existing single-family home by Town Board special permit. It can only be occupied by full-time employees of the household, and the owner must live in the main house.

Conditions the code attaches:

The allowance is limited to the single-family districts named in § 215-88.1, so it does not reach R-W, PW, BU, O, LI, LI-2 or RRBR.
A freestanding unit needs at least two acres. A unit inside the principal house needs a lot meeting the district's required area and a primary dwelling of 3,000 square feet or more of living area.
A separate building is capped at the lesser of 1,500 square feet or 25% of the primary dwelling including garage space.
A separate building must meet the same yard and setback requirements as a primary residence in that district and cannot sit between the primary residence and the access road.
Proof of employment must be provided to the town each January and again whenever ownership of the property changes.
The Town Board can revoke the special permit if any condition is violated or ceases to exist, and can attach further reasonable conditions when it is granted.

ADUs vs. short-term rentals in Stony Point

Short-term rentals prohibited for Town of Stony Point. Stony Point bars rentals of less than 29 days in its residential districts, and transient rental of a dwelling unit is not a listed permitted use in any district under Chapter 215. 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.
